SAFETY INFORMATION
IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS
AVOIDING THE RISK TO CHILDREN
DANGER:
• RISK OF CHILD DROWNING. Extreme caution must be exercised to prevent unauthorized access by children. To avoid accidents, ensure that children cannot
use a spa unless they are supervised at all times.
WARNING:
• To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times.
• To reduce the risk of injury, lower water temperatures are recommended for young children. Children are especially sensitive to hot water.
DO:
• Make sure you always lock the child resistant locks after using the spa for your children’s safety. Every Caldera® spa is equipped with a locking cover that meets
the ASTM F1346-91 Standard for Safety Covers.
• Test the water temperature with your hand before allowing your child to enter the spa to be sure that it’s comfortable. Children are especially sensitive to hot
water.
• Remind children that wet surfaces can be very slippery. Make sure that the children are careful when entering or exiting the spa.
DON’T:
• Allow children to climb onto the spa cover.
• Allow children to have unsupervised access to the spa.
AVOIDING THE RISK OF ELECTROCUTION
Risk of electrocution
• Connect only to a grounded source.
• Do not bury the power cord. A buried power cord may result in death or serious personal injury due to electrocution if direct burial-type cable is not used, or if
improper digging occurs.
• A ground terminal (pressure wire connector) is provided on the control box inside the unit to permit connection of a minimum No. 10 AWG solid copper bonding
conductor between this point and any metal equipment, metal water pipe, metal enclosures of electrical equipment, or conduit within five feet (1.5 m) of the unit
as needed to comply with local requirements.
WARNING:
• To reduce the risk of electrical shock, replace a damaged cord immediately. Failure to do so may result in death or serious personal injury due to electrocution.
• Your spa is provided with a Ground Fault Circuit Interrupter for user and equipment protection. To ensure proper operation of this important safety device, test
according to the following instructions per electrical configuration.
Cord-Connected 115 volt, 20 amp models: The GFCI is located at the end of the power cord. Before each use, with the unit operating, push the TEST button.
The unit should stop operating and the GFCI power indicator will go out. Wait 30 seconds and then reset the GFCI by pushing the RESET button. The GFCI
power indicator will turn on, restoring power to the spa. If the interrupter does not perform in this manner, there may be an electrical malfunction and with it, the
possibility of an electric shock. Disconnect the power until the problem has been corrected.
230 volt, permanently installed or converted models:
• A ground terminal is provided on the terminal block located inside the control box. To reduce the risk of electric shock, connect this terminal to the grounding
terminal of your electrical service or supply panel with a continuous green, insulated copper wire. The wire must be equivalent in size to the circuit conductors
supplying the equipment. In addition, a bonding terminal (pressure wire connector) is provided on the outside of the control box for bonding to local ground
points. To reduce the risk of electric shock, this connector should be bonded with a No. 10 AWG solid copper wire to any metal ladders, water pipes, or other
metal within 5 feet (1.5 m) of the spa to comply with local requirements. The means of disconnection must be readily accessible, but must be installed at least 5
feet (1.5 m) from the spa.
• Your spa is provided with a suitably rated circuit breaker to open all ungrounded supply conductors.
• Your spa uses ground fault circuit interrupters in the electrical subpanel. Before each use of the spa and with the unit operating, push the Test button on each
breaker. The switch should click over to the “Trip” position. Wait 30 seconds and reset each GFCI breaker by switching it completely off and then completely on.
The switch should then stay on. If either of the interrupters does not perform in this manner, it is an indication of an electrical malfunction and the possibility of
an electric shock. Disconnect the power until the fault has been identified and corrected.

SAFETY INFORMATION
DANGER: RISK OF ELECTRICAL SHOCK
• Install spa at least 5 feet (1.5 m) from all metal surfaces. A spa may be installed within 5 feet of a metal surface if each metal surface is permanently connected
by a minimum No. 10 AWG solid copper conductor attached to the wire ground connector on the terminal box that is provided for this purpose if in accordance
with National Electrical Code ANSI/NMFPA70-1993.
• Do not permit any electrical appliances, such as a light, telephone, radio, or television within 5 feet (1.5 m) of a spa. Failure to maintain a safe distance may
result in death or serious personal injury due to electrocution if the appliance should fall into the spa.
• Install your spa in such a way that drainage is away from the electrical compartment and from all electrical components.
DO:
• Be sure your spa is connected to the power supply correctly - use a licensed electrical contractor.
• Disconnect the spa from the power supply before draining the spa or servicing the electrical components.
• Test the Ground Fault Circuit Interrupter(s) before each use.
DON’T:
• Use the spa with the equipment compartment door removed.
• Place electrical appliances within 5 feet (1.5m) of the spa.
• Use an extension cord to connect the spa to its power source. The cord may not be properly grounded and the connection is a shock hazard. An extension
cord may cause a voltage drop, which will cause overheating of the jet pump motor and motor damage.
• Attempt to open the electrical control box. There are no user serviceable parts inside.
RISKS TO AVOID
DANGER: RISK OF INJURY
• To reduce the risk of injury to persons, DO NOT remove floating weir, basket, and filter located in the filter compartment while the spa is running.
• The suction fittings in the spa are sized to match the specific water flow created by the pump. Never replace a suction fitting with one rated less than the flow
rate marked on the original suction fitting.
• There is a danger of slipping and falling. Remember that wet surfaces can be very slippery. Take care when entering or exiting the spa.
• Never operate spa if the suction fittings are broken or missing.
• People with infectious diseases should not use the spa.
• Keep any loose articles of clothing or hanging jewelry away from rotating jets or other moving components.
Increased side effects of medication
• The use of drugs, alcohol or medication before or during spa use may lead to unconsciousness with the possibility of drowning.
• Persons using medications should consult a physician before using a spa; some medication may cause a user to become drowsy, while other medication may
affect heart rate, blood pressure, and circulation.
• Persons taking medications which induce drowsiness, such as tranquilizers, antihistamines or anticoagulants should not use the spa.
Health problems affected by spa use
• Pregnant women should consult a physician before using spa.
• Persons suffering from obesity or with a medical history of heart disease, low or high blood pressure, circulatory system problems, or diabetes should consult a
physician before using spa.
Unclean water
• Keep the water clean and sanitized with correct chemical care. The recommended levels for your Caldera® spa are:
Free Available Chlorine (FAC):
Water pH: 7.4-7.6
3.0-5.0 ppm
Total Alkalinity:
Calcium Hardness:
125-150 ppm
150-200 ppm
(Refer to Water Quality and Maintenance section for complete instructions.)
IMPORTANT: Turn jet pump on for at least ten minutes after adding ANY spa water chemicals into the filter compartment.
• Clean the filter cartridge monthly to remove debris and mineral buildup which may affect the performance of the hydromassage jets, limit the flow, or trip the
high-limit thermostat which will turn off the entire spa.
AVOIDING THE RISK OF HYPERTHERMIA
Prolonged immersion in hot water can result in HYPERTHERMIA, a dangerous condition which occurs when the internal temperature of the body reaches a level above
normal (98.6°F). The symptoms of hyperthermia include unawareness of impending hazard, failure to perceive heat, failure to recognize the need to exit the spa, physical
inability to exit the spa, fetal damage in pregnant women, and unconsciousness resulting in a danger of drowning.
WARNING:
The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia in hot tubs and spas.

SAFETY INFORMATION
TO REDUCE THE RISK OF INJURY:
• The water in the spa should never exceed 104°F (40°C). Water temperatures between 100°F (38°C) and 104°F (40°C) are considered safe for a healthy adult.
Lower water temperatures are recommended for extended use (exceeding 10 minutes) and for young children. Extended use can cause hyperthermia.
• Pregnant or possibly pregnant women should limit spa water temperatures to 100°F (38°C). Failure to do so may result in permanent injury to your baby.
• Do not use spa immediately following strenuous exercise.
AVOIDING THE RISK OF SKIN BURNS:
• To reduce the risk of injury, before entering a spa the user should measure the water temperature with an accurate thermometer, since the tolerance of
temperature-regulating devices may vary by as much as 5°F (2°C).
• Test the water with your hand before entering the spa to be sure it’s comfortable.
SAFETY SIGN
Each Caldera® spa is shipped with a SAFETY SIGN in the owner’s package. The sign, which is required as a condition of Product Listing, should be permanently
installed where it is visible to the users of the spa. To obtain additional SAFETY SIGNS, contact your Caldera dealer and request Part #003021.
IMPORTANT SPA INSTRUCTIONS
The following contains important spa information, and we strongly encourage you to read and apply them.
DO:
• Use and lock the vinyl cover when the spa is not in use, whether it is empty or full.
• Follow the Spa Care and Maintenance recommendations stated in this manual.
• Use only approved accessories and recommended spa chemicals and cleaners.
DON’T:
• Leave the spa exposed to the sun without water or the vinyl cover in place. Exposure to direct sunlight can cause solar distress of the shell material.
• Roll or slide the spa on its side. This will damage the siding.
• Lift or drag the cover by using the cover lock straps; always lift or carry the cover by using the handles.
• Attempt to open the electrical control box. There are no user serviceable parts inside. Opening of the control box by the spa owner will void the warranty. If you
have an operational problem, carefully go through the steps outlined in the Troubleshooting section. If you are not able to resolve the problem, contact your
authorized Caldera dealer. Many problems can easily be diagnosed over the telephone by an Authorized Service Technician.
SAVE THESE INSTRUCTIONS
INSTALLATION
SITE AND SELECTION PREPARATION
You probably have a spot picked out for your new spa, whether it’s indoors or outdoors, on a patio or on a deck. Just make sure you check the following:
• Always put your spa on a structurally sound, level surface. A filled spa can weigh a great deal. Make certain that the location you choose can support the weight
of your filled spa.
• Don’t forget to level your spa before filling it (see the spa leveling preparation on the next page).
• Locate your equipment compartment, which houses all of the electrical components, in a place where water will drain away from it. Allowing water into the
equipment compartment can damage the electronics, or may result in tripping your house’s circuit breaker.
• Leave yourself easy access to the Ground Fault Circuit Interrupter (GFCI) for testing. The GFCI is located at the end of the power cord, or at the subpanel of a
hard-wired spa.
• Never let water get into the subpanel or into the electrical outlet that your spa is plugged into. Consult your local code authority to determine if an electrical
outlet with a cover is required for your installation.
• Leave access to the equipment compartment for periodic spa care and maintenance.
WARNING: Damage to the spa’s equipment compartment components or internal plumbing as a result of rodent infestation is NOT covered under your
warranty!

INSTALLATION
OUTDOOR AND PATIO INSTALLATION
No matter where you install your new spa, it’s important that you have a solid foundation to support it. Structural damage to the spa, resulting from incorrect installation
or placement on an inadequate foundation, is not covered under the spa’s limited warranty.
If you install the spa outdoors, we recommend a reinforced concrete pad at least four inches thick. The reinforcing rod or mesh in the pad should be attached to a bond wire.
DECK INSTALLATION
To be certain your deck can support your spa, you must know the deck’s maximum load capacity. Consult a qualified building contractor or structural engineer. To find
the weight of your spa, its contents and occupants, refer to the Spa Specifications chart on the back cover. This weight per square foot must not exceed the structure’s
rated capacity, or serious structural damage could result.
INDOOR/BASEMENT INSTALLATION
Be aware of some special requirements if you place your spa indoors. Water will accumulate around the spa, so flooring materials must provide a good grip when wet.
Proper drainage is essential to prevent a build-up of water around the spa. When building a new room for the spa it is recommended that a floor drain be installed. The
humidity will naturally increase with the spa installed indoors. Water may get into woodwork and produce dry rot, mildew, or other problems. Check for airborne
moisture’s effects on exposed wood, paper, etc. in the room. To minimize these effects, it is best to provide plenty of ventilation to the spa area. An architect can help to
determine if more ventilation must be installed.
Your spa dealer can help you with local information such as zoning regulations and building codes.
WARNING: Please keep the area around your spa well ventilated when it is installed indoors or in a confined area. Inadequate ventilation around the spa could
cause a build-up of a higher-than-normal concentration of spa chemicals and/or bacterial fragments. These dispersed spa chemicals and/or bacterial fragments can be
inhaled, and may result in breathing difficulties or lung damage in certain people suffering from a compromised immune system or respiratory infection. If you or other
bathers are affected by this condition, please seek medical attention as soon as possible.
In addition to the above, properly clean and maintain your spa as follows:
• Follow all procedures in this owner’s manual and printed instructions on all water care (chemical) products packaging.
• Test the water regularly to ensure proper levels of sanitizers, pH, and other water care requirements.
• Drain, clean, and refill your spa with fresh water on a regular schedule, and in accordance with this owner’s manual.
• Clean the filter(s) at least once per month.
• Check to make sure you have proper circulation throughout your spa water system.
• Have spa users bathe before entering the spa water.
SPA LEVELING PREPARATION
Concrete sloped at 1/2 inch (1.3 cm) per 10 feet (305 cm) is preferred so that rain water and water spillover will run off and not puddle underneath the spa (water under
the spa for long periods of time may cause the wood to deteriorate). Other options are brick, stepping stone, or blocks.
It is important to note that soft surfaces, even when stepping stones are used to evenly distribute the weight of the spa, will have a tendency to settle, thus resulting in
an unleveled spa.
NOTE: Placing the spa on grass or dirt may increase the amount of debris which is inadvertently brought into the spa water and may cause harm to your equipment as
well as the spa surface, which is not covered under warranty.

COVER INSTALLATION
SPA COVER INSTALLATION
• Place the cover squarely on the spa.
COVER
• Position the tie-down locks included with your cover on the side of the spa so that they are easily reached by the cover
TIE-DOWN STRAP
tie-down straps. Allow for about 1/2” to 3/4” slack in the straps to make it easy to insert straps into locks and to
compensate for vinyl shrinkage in cold weather.
LOCK
KEY
• Attach the locks with the screws provided and insert the cover tie-down straps into the locks.
SCREW (2)
NOTE: Keeping the cover in place any time the spa is not in use will reduce the amount of time the heater operates, thereby
minimizing operating costs.
DANGER. RISK OF INJURY.
• Never leave a spa uncovered or unattended.
• Never leave a spa cover unlocked.
• Do not stand, sit, or lie on the cover.

ELECTRICAL INSTALLATION
SELECTING THE VOLTAGE FOR YOUR SPA
The Cumberland® and Aventine™ spas are designed to operate at either 115 or 230 volts, 60 Hz, while the Olympia spa model requires a dedicated 230 volt power supply.
When the spa is connected to 115 volts, the heater will provide approximately 1000 watts of heat only when the pump is operating in LOW speed and the thermostat is
calling for heat. When the spa is connected to 230 volts, the heater will provide approximately 4000 watts of heat when the pump is operating in LOW or HIGH speed and
the thermostat is calling for heat.
All electrical connections must be made in accordance with the wiring information contained in the electrical control box or on the back of the field wiring access panel
of the equipment module.
115 VOLT INSTALLATION
Spas provided with a factory- installed power supply cord are to be plugged into a grounded, grounding type, 115 volt, 20 ampere receptacle (Cumberland and Aventine
model). No other electrical appliance or fixture can be used on this circuit.
IMPORTANT: Under NO circumstances should an extension cord be used. Use of an extension cord will seriously degrade the performance of the equipment module
and can create an electrical hazard.
230 VOLT INSTALLATION
When using 230 volt power supply, installation of a 50 amp dedicated circuit is required. Your spa must be hardwired direct to a GFCI-protected subpanel by a licensed
electrician. A wiring diagram is provided inside the equipment module showing where the connections are to be made.
ELECTRICAL REQUIREMENTS AND PRECAUTIONS
Your Caldera® spa has been carefully designed to give you maximum safety against electrical shock. Connecting the spa to an improperly wired circuit will negate many
of the spa’s safety features. Improper wiring may also cause electrocution, risk of fire, and other risks of injuries. Please read and follow the electrical installation
requirements and instructions for your spa completely!
115-230 VOLT CONVERSION
(CUMBERLAND® AND AVENTINE™ MODELS)
Refer to the following instructions to convert your 115 volt Highland series spa to a 230 volt spa.
NOTE: Converting the spa to 230 volts operation should only be done by an authorized service agent or a qualified electrician.
The conversion requires a subpanel (230 volt) which may be purchased from your Authorized dealer. Ask for part # 38661
1. Disconnect the power cord from the house receptacle.
2. Remove the screws and open the equipment compartment door.
3. Remove the screws from the control box.
4. Open the control box cover.
5. Remove the power cord wires, and the power jumper wire (from line 2 and neutral) on the line side of the terminal block.
6. Locate Program Jumper JMP 1, using a pair of needle nose pliers, carefully move the jumper from pins 2 and 3 and move to pins 1 and 2 (see Figure below).
A licensed electrician must install the subpanel (available from your dealer) to supply power to the spa. The subpanel must be placed in sight of the spa at a minimum
distance of 5 feet away.

START-UP AND REFILL PROCEDURES
Your Caldera® spa has been thoroughly tested during the manufacturing process to ensure reliability and long-term customer satisfaction. A small amount of water may
have remained in the plumbing after testing and, as a result, may have spotted the spa shell or the spa siding prior to delivery. Before filling the spa, wipe the spa shell
clean with a soft rag.
The following instructions must be read and followed exactly to ensure a successful start-up or refill.
CAUTIONS
• Do not fill the spa with hot water, as tripping of the high-limit thermostat may result.
• DO NOT CONNECT POWER TO AN EMPTY SPA. Power to the spa automatically activates critical components within the spa, such as controls,
heater, and other systems. If power is supplied to these components prior to the spa being filled, the components will be damaged, and this may
result in a non-warranty component failure.
• Do not use your spa after filling until all of the steps listed below are completed.
• Do not add chlorine if treating your spa with polyhexamethylene biguanide (Biguanide, PHMB, eg. BaquaSpa®) sanitizer.
• Before filling your spa for the first time, remove the equipment compartment door and check to ensure that the unions on either side of the pump(s)
and heater are hand-tight.
1. Ensure that the drain is closed and remove the filter compartment cover, skimmer basket, weir, and filter. Then insert the end of a garden hose into the filter canister
and begin filling the spa. The water level of your Caldera spa should be maintained at a level one inch above the highest jet in the spa. Reinstall the filter and then
the skimmer basket, and weir once the spa is filled.
IMPORTANT: Watkins® Manufacturing Corporation does not recommend that the spa be filled with “softened” water, as this may damage the spa’s equipment.
2. AFTER the spa has been filled with water and the equipment compartment door is secured, power must be applied to the spa.
• 115 volt models: Connect the GFCI to the waterproof receptacle and push the RESET button on the GFCI.
• 230 volt models: Open the door of the electrical subpanel and reset the GFCI breaker. Close and secure the subpanel door.
3. The jet pump(s), heating system and all internal plumbing will achieve a partial prime as the spa is filled. To check the operation of the jet system and to purge any
remaining air from the heating system, push the “JETS” button on the control pad twice (three times for the Olympia) to make the jet pump(s) run on high speed for
one minute. Once the jet system is fully operational (as indicated by strong, non-surging jets), priming of the spa is complete. If you do not feel a steady stream of
water from your jets, refer to the instructions for priming the pump in the SPA TROUBLESHOOTING section in the back of this manual.
4. Adjust Total Alkalinity (TA) to 125 ppm, Calcium Hardness (CH) to 150 ppm, then spa water pH to between 7.4 and 7.6. These procedures are listed in the “Water
Quality and Maintenance” section.
IMPORTANT: Activate the Clean cycle (Press “SET”, then “JETS” button) before adding spa water chemicals directly into the filter compartment.
OPERATION NOTE: Adjusting the Total Alkalinity as the first step is important, as out-of balance TA will affect your ability to adjust the pH correctly and will prevent
the sanitizer from operating effectively.
5. Activate the Clean cycle then superchlorinate the spa water by adding 1-1/2 teaspoons of chlorine (sodium dichlor) per 250 gallons (950 liters) of spa water.
6. Set the temperature control to the desired temperature between 100°F (38°C) and 104°F (40°C), then place the spa cover on the spa and allow the water
temperature to stabilize (approximately 24 hours). Make sure you secure the cover in place using the cover locks. Periodically check the spa water temperature.
When the water temperature climbs above 90°F (32°C), proceed to the next step.
7. Test the spa water for Free Available Chlorine (FAC) residual. If the residual is between 3 and 5 ppm on the test strips go on to the next step. If the residual is less
than 3 ppm, activate the Clean cycle then superchlorinate the spa water by adding 1-1/2 teaspoons of chlorine (sodium dichlor) per 250 gallons (950 liters) of spa
water.
8. Recheck the Total Alkalinity (TA) at 125 ppm, Calcium Hardness (CH) at 150 ppm, then spa water pH at between 7.4 and 7.6.
OPERATION NOTE: Make sure you adjust your Total Alkalinity first, as an out-of-balance condition will affect your ability to adjust the pH correctly, and will affect
the sanitizers effectiveness. The spa is ready for use when the spa water has circulated and the chlorine level remains between 3 ppm and 5 ppm.
9. The spa temperature is pre-programmed to reach 102F (39°C), and will normally do so within 18 to 24 hours. You may raise the water temperature by pressing the
Temp Plus (▲) button on the control panel, or lower it by pressing Temp Minus (▼) button. After a few hours, the water temperature will remain within 3˚F (1.5°C) of
your selected temperature.
OPERATION NOTES:
1. Your spa is equipped with a ten-minute timer delay on the heating/maintenance mode. Whenever the jet pump has been turned off (and a three-degree temperature
drop has occurred) or the temperature control has been turned up, it will take ten minutes before the low speed of the jet pump and heater become activated.
Always push the “JETS” button to turn off the jet pump when exiting the spa. In the standard 115 volt, 20 amp electrical configuration, the heating system does not
operate simultaneously with the high speed pump. On the other hand, on the 230 volt system, the heating system does operate simultaneously with the high speed
pump.
2. The spa controller has an automatic one-hour “time-out” feature should the high speed jet mode be left on inadvertently. After one hour of continuous operation,
the controller will automatically return to the maintenance/heating mode.
3. The spa controller also has a six-hour “time-out” feature should the light be left on inadvertently. After six hours of continuous operation, the controller will
automatically turn the light off.

OPERATING INSTRUCTIONS
SPA-SIDE CONTROL OPERATION
Your spa-side control panel consists of an LED display and convenient
touch pads that allow you to set the water temperature and adjust the
skim/filter cycle settings, as well as control the hydrotherapy jets, and light
from
spa-side.
LED DISPLAY
The LED display on your spa-side control panel continually shows the spa’s
actual water temperature. In certain situations, it will also display other
messages. See TROUBLESHOOTING section.
TEMPERATURE CONTROL
The set temperature range is from 80°F (27°C) to 104°F (40°C). Higher
temperatures can be reached which is indicated by one of these four
settings: uT1,uT2, uT3, & uT4. These settings get progressively warmer, with
uT4 the highest at approximately 107.5°F (42°C). (Temperatures of any
setting may rise slightly depending on the current use and condition of your spa, and on outside temperature.) To reach the u1-u4 temperature range, press the TEMP
▲ button until 104°F (40°C) is displayed, then push down and hold the TEMP ▲ button for 5 seconds until the uT1 is illustrated.
The factory-set temperature is 102°F (39°C). Whenever power is disconnected and then reconnected to the spa, the water temperature will automatically seek this
temperature, unless you set it otherwise using the temperature controls.
Pressing the TEMP ▲ button displays the spa’s set temperature. To increase the set temperature, press the TEMP ▲ button again, once for each degree of increased
temperature desired. If you hold the button down, the set temperature will increase by one degree every half second. When the set temperature has been reached, the
“READY” icon will diplay.
Pressing the TEMP ▼ button displays the spa’s set temperature. To decrease the set temperature, press the TEMP ▼ button again, once for each degree of
decreased temperature desired. If you hold the button down, the set temperature will decrease by one degree every half second. When the set temperature has been
reached, the “READY” icon will diplay.

OPERATING INSTRUCTIONS
MYSTIQUE® LED LIGHTING (OPTIONAL)
The Mystique LED lighting system allows you to brighten up your spa experience through different multi-colored lights: blue, aqua, green, amber, red, and magenta. You
can choose one stationary color or you can cycle through all the colors with the automatic color wheel.
To install Mystique LED lighting system, you will need to contact your Caldera Dealer.
To activate, press the “SET” button, then the “LIGHT” button on the control panel. The LIGHT icon will flash once color wheel is active. To select a specific color, push
the “LIGHT” button (within 5 seconds) while the desired color is displayed. If 5 seconds have passed after color wheel activation, you will need to press “SET”, then
“LIGHT” to select a specfic color. The Mystique LED lighting option is a great way to personalize your spa experience.
LOCK FEATURES
The locking features, TEMPERATURE LOCK and SPA LOCK, are enabled from the control panel by a specific combination of buttons. Once enabled, a lock will remain
active until the specific button combination is applied to disable the lock. Even if power is disconnected from the spa and soon thereafter reapplied (such as a power
outage), the lock will remain in place.
SPA LOCK
The Spa Lock feature deactivates all of the functions of the control panel. It is generally used to prevent unwanted use of the spa.
To activate the Spa Lock, press “SET” button then “TEMP ▼” button. The word “SLOC” in the display will confirm activation.
To deactivate the Spa Lock, press “SET” button then “TEMP ▼” button. At this point, the “SLOC” will no longer be illuminated in the display.
TEMPERATURE LOCK
The Temperature Lock feature deactivates the temperature control function from the control panel. All other functions on the control panel will operate normally.
Temperature Lock is most often used by those who do not want others to change the set temperature of the spa water.
To activate the Temperature Lock, press “SET” button then “TEMP ▲ “ button. The word “TLOC” in the display will confirm activation.
To deactivate the Temperature Lock, press “SET” button then “TEMP ▲ “ button. At this point, the “TLOC” will no longer be illuminated in the display.
FILTER CYCLES
Your spa will automatically turn the filter cycle on twice each day. When the spa is first powered up the automatic filter cycle will wait 10 minutes before
starting. A 1.5 hour filter cycle using the low speed of the jet pump is the programmed default filter cycle time. The display will read 1:30. The filter
cycle occurs twice a day (every 12 hours).
®
NOTE: The optional Monarch and PureWaterTM ozone systems only work during the filter cycles.
To modify the length of either filter cycle:
A. Press and hold the “SET” button for approximately three seconds (The filtration ion will flash during programming).
B. Press the “LIGHT” button to select the Filter Cycle 1 or 2 (a F1 or F2 will flash in the display). NOTE: Each filter cycle can be set independently.
C. Using the TEMP ▲ or the TEMP ▼ button, adjust the length of filtering time desired (0 to 6 hours).
D. Programing will then be saved 10 seconds after the last button is pushed.
The filter cycle will activate the low speed of the jet pump for the entire cycle. When activated, the filter cycle icon on the display is turned on. If the temperature
exceeds the set point by three degrees F for more than three hours, the system will cancel the FILTER cycle and the filter cycle icon will blink for the remaining filter
cycle time. Should the temperature cool down to 1.5 degrees F within the set point before the end of the cycle, the cycle will resume for the rest of the time. Should you
use the spa during the filter cycle by placing the jet pump on high speed, the filter cycle icon will blink. Once the jet pump has been shut off, a ten minute tranquil mode
begins (filter cycle icon will be blinking during tranquil mode) before the filter cycle will resume. The blinking filter cycle icon indicates that the filter cycle timer is still
counting, but the cycle has been temporarily interrupted.
NOTE: The interrupted time of a filter cycle is not extended after the filter cycle resumes. Power interruptions of the spa will reset the filter cycle to the default 1.5 hour
cycle time and begin 10 minutes after spa regains power.
OPERATION NOTE: For proper water-circulation during filtration cycles, rotate the air control valves counterclockwise to the off position.
MANUAL CLEAN CYCLE
The clean-up cycle operates in the following manner: Jet pump 1 runs for ten minutes on high speed.
This system is initiated by pressing the “SET” button, then “JETS” button. The Filter and Jets icon will flash.

WATER QUALITY AND MAINTENANCE
SLEEP MODE
The Sleep Mode operation is a feature that minimizes pump operation during evening hours. For example, if Filter Cycle 1(F1) is set to activate at
8:00am, by default, Filter Cycle 2 (F2) will be set to activate at 8:00pm (12 hrs. later). During 8:00pm to 8:00am, if the spa should call for heat, the
pump and heater will activate to heat the spa. However, when in Sleep Mode, should the spa call for heat, the pump and heater will be
suspended until the activation of Filter Cycle 1 at 8:00am, to minimize pump activation during evening hours. NOTE: If water temperature drops below 80 degrees,
pump and heater will automatically activate to prevent temperature from dropping further.
To activate the Sleep Mode feature, press and hold “TEMP ▲ “ and “TEMP ▼“ buttons together for 3 seconds. This will activate the feature and override the normal filter
cycle operation. When these buttons have been engaged, the Sleep Mode icon will illuminate on the control panel display, indicating the feature is active. To deactivate
this feature, simply press and hold the specific buttons in the same manner once again.
AIR CONTROL
The Air Control(s) located next to your spa-side control panel allows you to change the power of the jets by regulating the amount of air that is mixed with the water
coming out of the jets.
HYDRO JETS
MagnaTM Jets – The larger jets in your spa allow you to re-direct the jet stream by changing the position of the nozzle.
You can also regulate the force of the massage by rotating the jet face clockwise to reduce the force or counter-clockwise to increase the force. Notice that turning off
the flow to some jets increases the flow to the other jets. To avoid damage to your spa’s plumbing and components, do not turn off more than half of these jets at
the same time.
MagnaSsageTM rotating nozzles are available from your dealer, to replace the directional adjustable nozzles in the Magna Jets.
®
Euro Directional Jets – The small euro jets deliver a direct, precision massage. You may also purchase Euro-Pulse assemblies from your dealer that would replace the
Euro directional jets to provide a pulsating, rotary massage. This can be accomplished by simply twisting off the Euro jet face, adding the nozzle and nozzle retainer,
then reinstalling the Euro jet face.
DIVERTER VALVE
®
The diverter valve on the Cumberland spa model allows you to direct the flow of water from the pump to several combinations of jets. The functions of this diverter
valve can best be learned by experimentation as follows:
1. Set all air controls to the “ON” position by rotating counterclockwise.
2. Turn on the pump.
3. Turn the handle on the diverter valve and see which groups of jets are affected. (Note that you can adjust the diverter valve to any position between the two possible
extremes to achieve the jet pressure that feels best to you.)
IMPORTANT: Your spa is not designed to provide full power to all jets when the diverter valve is in the “mid” position.
WATERFALL VALVE
The OlympiaTM spa is equipped with the cascading waterfall feature. It is activated by turning JETS2 and turning the valve, located on the front interior wall,
counterclockwise. The flow is regulated by turning the waterfall valve to the desired position.
WATER QUALITY AND MAINTENANCE
It’s important to have clean water. Water maintenance is one of the least understood, yet most important areas of spa ownership. Your dealer can guide you through the
process of achieving and maintaining perfect water in your spa, given your local conditions. Your program will depend on your water’s mineral content, how often you
use your spa, and how many people use it.
GENERAL INFORMATION
THE THREE FUNDAMENTAL AREAS OF WATER MAINTENANCE:
• Water Filtration
• Chemical Balance/pH Control
• Water Sanitation
Water Sanitation is the responsibility of the spa owner, achieved through the regular and periodic (daily, if necessary) addition of an approved sanitizer. The sanitizer will
chemically control the bacteria and viruses present in the fill water or introduced during use of the spa. Bacteria and viruses can grow quickly in undersanitized spa
water.
The water’s chemical balance and pH control are also the responsibility of the spa owner. You’ll have to add chemicals to maintain proper levels of Total Alkalinity (TA),
Calcium Hardness (CH) and pH. Proper water balance and pH control will minimize scale buildup, extend the life of the spa, and allow the sanitizer to work at an
optimum level.

WATER QUALITY AND MAINTENANCE
METHODS FOR TESTING THE SPA WATER
Accurate water testing and analysis is an important part of effectively managing your spa water. You must have the ability to test for:
•
•
Total Alkalinity (TA)
Calcium Hardness (CH)
•
•
pH
Sanitizer
Two types of testing methods are recognized and recommended by Watkins® Manufacturing Corporation:
The Reagent Test Kit is a method which provides a high level of accuracy. The reagents come in either liquid or tablet form.
Test Strips are a convenient testing method used by many spa owners. Keep in mind that test strips are susceptible to heat and moisture contamination, which will
result in inaccurate readings.
IMPORTANT: Always read and carefully follow the directions included with the Test Kit or Test Strips to ensure the accuracy of the test results.
BASIC CHEMICAL SAFETY
When using chemicals, read the labels carefully and follow directions precisely. Though chemicals protect you and your spa when used correctly, they can be hazardous
in concentrated form. Always observe the following guidelines:
• Allow only a responsible person to handle spa chemicals. KEEP THEM OUT OF THE REACH OF CHILDREN.
• Accurately measure the exact quantities specified, never more. Do not overdose your spa.
• Handle all containers with care. Store in a cool, dry, well ventilated place.
• Always keep chemical containers closed when not in use. Replace caps on their proper containers.
• Don’t inhale fumes or allow chemicals to come in contact with your eyes, nose, or mouth. Wash your hands
immediately after use.
• Follow the emergency advice on the product label in case of accidental contact, or if the chemical is swallowed.
Call a doctor or the local Poison Control Center. If a doctor is needed, take the product container along with you
so that the substance can be identified.
• Don’t let chemicals get on surrounding surfaces or landscaping.
• Don’t use a vacuum cleaner to clean up chemical spills.
• Never smoke around chemicals. Some fumes can be highly flammable.
• Don’t store any chemicals in the spa equipment compartment.

HOW TO ADD CHEMICALS TO THE WATER
IMPORTANT: All spa water chemicals, including granulated dichlor, MPS (monopersulphate) granulated pH increaser or decreaser, granulated total alkalinity increaser,
calcium hardness increaser, liquid stain and scale inhibitor, and liquid de-foamer must always be added directly into the filter compartment while the jet pump is running,
and it must run for a minimum of ten minutes.
To Administer Spa Water Chemicals:
1. Fold back the cover. Carefully remove and set aside the filter compartment cover (if applicable).
2. Press the “JETS” button twice to turn the jet pump on high.
3. Carefully measure the recommended amount of chemical and slowly pour it into the filter compartment. Use care not to splash chemicals on your hands, in your
eyes, on the spa shell surface or on the siding.
4. Replace the filter compartment cover (if applicable). After ten minutes, shut off the jet pump(s) and close and lock the cover to complete the procedure. Risk of
Drowning: Never leave an open spa unattended!
WARNING: High sanitizer levels can cause discomfort to the user’s eyes, lungs and skin. Always allow the sanitizer level to fall to the recommended range before
using the spa.
IMPORTANT “SUPER CHLORINATION/NON-CHLORINE SHOCK TREATMENT” NOTE: After administering a super chlorination treatment or non-chlorine shock to
your spa, leave the cover open for a minimum of 20 minutes to allow the oxidizer gas to vent. A high concentration of trapped oxidizer gas which may exist as a result of
the shock treatment (not daily sanitation) may eventually cause discoloration or vinyl degradation to the bottom of the cover. This type of damage is considered chemical
abuse and is not covered under the terms of the limited warranty.
THE WATKINS® SPA WATER MAINTENANCE PROGRAM
Each step in your water maintenance program is dependent on the completion of the previous steps. Omitting a step or failing to reach the recommended range may
cause an imbalance in your water’s chemistry. Unbalanced water chemistry can damage the spa and its components, as well as cause discomfort for the user.
BALANCING THE TOTAL ALKALINITY (TA)
A. The recommended Total Alkalinity (TA) for your spa water is 125-150 ppm.
B. Total Alkalinity is a measure of the total levels of carbonates, bicarbonates, hydroxides, and other alkaline substances in the water. TA is referred to as the water’s
“pH buffer”. In other words, it’s a measure of the ability of the water to resist changes in pH level.
C. If the TA is too low, the pH level will fluctuate widely from high to low. Fluctuations in pH can cause corrosion or scaling of the spa components. Low TA can be

WATER QUALITY AND MAINTENANCE
corrected by adding sodium hydrogen carbonate (pH/Alkalinity Up).
D. If the Total Alkalinity is too high, the pH level will tend to be high and may be difficult to bring down. It can be lowered by using sodium bisulfate (pH/Alkalinity
Down).
E. Once the TA is balanced, it normally remains stable, although the addition of more water with a high or low alkalinity will raise or lower the TA reading of the water.
F. When the Total Alkalinity is within the recommended range, proceed to the next step.
BALANCING THE CALCIUM HARDNESS (CH)
A. The recommended Calcium Hardness (CH) level for your spa is 150-200 ppm.
B. Calcium Hardness is a measure of the total amount of dissolved calcium in the water. Calcium helps control the corrosive nature of the spa’s water. That’s why
calcium-low water (commonly known as “soft” water) is not recommended. It is very corrosive to the equipment, and can cause staining of the spa shell.
C. If the CH is too high (commonly known as “hard water”), formation of scale on the spa’s shell surface and equipment can result. CH can be decreased by
dilution–a mixture of 75% hard and 25% soft water will usually yield a reading within the correct range. If soft water is not available or practical for you, a
stain and scale inhibitor should be added to the spa water, according to label instructions.
D. If the CH is too low add CH Increaser.
E. Once the CH is balanced, it normally remains stable, although the addition of more water with a high or low calcium content will raise or lower the CH reading of the water.
F. When the Calcium Hardness is within the recommended range, proceed to the next step.
BALANCING THE pH
A. The ideal pH level for your spa water is 7.4-7.6.
B. The pH level is the measure of acidity and alkalinity. Values above 7 are alkaline; those below 7 are acidic. Maintaining the proper pH level is extremely important for:
• Optimizing the effectiveness of the sanitizer.
• Maintaining water that is comfortable for the user.
• Preventing equipment deterioration.
C. If the spa water’s pH level is too low, the following may result:
• The sanitizer will dissipate rapidly.
• The water may become irritating to spa users.
• The spa’s equipment may corrode.
If the pH is too low, it can be increased by adding sodium hydrogen (pH/Alkalinity Up) carbonate to the spa water.
D. If the pH level is too high, the following may result:
• The sanitizer is less effective.
• Scale will form on the spa shell surface and the equipment.
• The water may become cloudy.
• The filter cartridge pores may become obstructed.
If the pH is too high, it can be decreased by adding sodium bisulfate (pH/Alkalinity Down) to the spa water.
NOTE: After adding sodium hydrogen carbonate, or sodium bisulfate, wait two hours before testing the water for pH. Measurements taken too soon may not be
accurate.
E. It is important to check the pH on a regular (weekly) basis. The pH will be affected by the bather load, the addition of new water, the addition of various chemicals,
and the type of sanitizer used.
F. When the pH is within the recommended range, proceed to the final step.
MAINTAINING THE SANITIZER LEVEL
A. Sanitizer is extremely important for killing algae, bacteria and viruses, and preventing unwanted organisms from growing in the spa. At the same time, you don’t
want too high a sanitizer level, or it can irritate your skin, lungs, and eyes.
B. Always maintain the sanitizer level in your spa at the recommended level for each type of sanitizer.
C. Watkins® recommends only the following sanitizers:
• Sodium Dichloro-s-Triazinetrione (sodium dichlor or chlorine)
• Baqua Spa® (please consult your Baqua Spa manual for instructions on the use of this product).
• Brominating Concentrate™ (one step granular bromine)
WARNING: DO NOT use tri-chlor chlorine, bromo-chloro-dimethyl-hydantoin (BCDMH), or any type of compressed bromine or chlorine, acid or any type of sanitizer
which is not recommended by Watkins® Manufacturing Corporation.

MONARCH® WATER CARE SYSTEM
The Monarch system is comprised of the following products:
• Monarch silver ion purifier introduces silver ions into the spa water, inhibiting bacteria growth. When combined with MPS or chlorine, oxidizes particulates in
the spa water.
• Monarch CD Ozone Generator - The Monarch high output ozone system is the only ozone purification system approved for installation in your Caldera® Spa.
The Monarch ozone system utilizes Corona Discharge (CD) technology to produce a higher concentration of ozone than is produced by competing chip style
CD or ultraviolet light ozone systems.
• Monopersulfate (MPS), Caldera Monarch Chlorine - Free Oxidizer is an oxidizing chemical used to prevent the buildup of contaminants, maximize sanitizer
efficiency, minimize combined chlorine, and improve water clarity.
• Sodium Dichlor (chlorine) is the only recommended sanitizer that will work in conjunction with all of the other products in this system..It is important to follow
the recommended application and maintenance programs outlined for each product’s use.
If the spa is being used over an extended period or time, such as a whole afternoon or evening, additional sanitizer will be needed.
A weekly “shock treatment” is required.
The shock treatment quickly destroys any remaining contaminants while revitalizing the silver ion purifier, allowing the silver ions to continue to be released into the
water. Without this weekly shock treatment, the silver ion purifier may stop releasing silver ions into the water.
To weekly “shock treat” your spa you may use either MPS or sodium dichlor. It will require much less sodium dichlor to administer the shock treatment than MPS (1
teaspoon of sodium dichlor has oxidizing capabilities comparable to 2 tablespoons of MPS). Sodium dichlor may be a more appropriate weekly shock for those users
that experience heavy bather load conditions.
IMPORTANT NOTE: MPS is an oxidizer, not a sanitizer.
MONARCH SILVER ION PURIFIER INSTALLATION INSTRUCTIONS
When replacing the silver ion purifier (every four months), it is highly recommended that the spa be drained and refilled at the same time. After refilling the spa with water,
balance the Total Alkalinity (TA), Calcium Hardness (CH) and pH to the recommended levels. Shock the spa by adding sodium dichlor.
1. Release the cover locks and fold back the cover.
2. Remove the filter compartment cover.
3. Make sure the filter compartment is clear of any floating objects.
4. Drain the spa using the recommended procedures found in the Owner’s Manual.
PLEASE NOTE: The Monarch® silver cartridge cannot be used with bromine, sodium bromide or biguanides. If you have previously used any of these products in the
spa, it is recommended that the shell and filter compartment be cleaned. It is also recommended that the filters be cleaned with a filter cleaner before the Monarch
cartridge is installed. (Review the shell and filter cleaning procedures.)
5. Push down slightly and turn filter basket counterclockwise to unlock, then pull out the basket and weir.
6. Grab handle and lift filter straight up and out.
IMPORTANT NOTICE: If you have used the spa prior to this installation, clean the filter to ensure optimal performance from the Monarch silver ion purifier. It is
recommended to clean the filter each time you replace the Monarch cartridge.

WATER QUALITY AND MAINTENANCE
7. FOR THE OLYMPIA AND CUMBERLAND: Insert the Monarch silver cartridge, into the 2.5” diameter standpipe at the bottom of the filter canister.
8. FOR THE AVENTINE: For initial silver ion installation only, a round gray adpator (PN 73770), will need to be glued onto the bottom of the filter basket. (See pg. 21)
9. Carefully replace the filter, the filter basket and weir.
10. Fill the spa as recommended (see Start-Up and Refill Procedures).
11. Replace the filter compartment cover.
12. Fold the cover back into place.
WARNING: Never use the spa with the filter cartridge, basket, or weir removed.
SILVER ION QUESTIONS AND ANSWERS
Questions: How are the silver ions added to the water?
Answers: The silver cartridge contains ceramic beads that are infused with silver. By placing the cartridge in the filter standpipe, it is subject to the flow of water created
by the operation of the jet pump. The flowing water, through a chemical erosion process, carries with it the silver ions necessary to add a sanitizing residual to the spa
water.
Questions: What happens if I do not add the weekly shock treatment?
Answers: The contaminants in the water may coat the silver cartridge’s ceramic beads, blocking the silver ions’ release into the water. When this occurs, there will be no
residual of silver ions present in the water, eliminating them from the sanitizing process.
Questions: How often should the Monarch silver cartridge be replaced?
Answers: The cartridge must be replaced every four months. Please refer to the instructions provided with each Monarch silver cartridge.
Questions: Why can’t I use bromine or biguanides instead of MPS or chlorine?
Answers: Bromine or biguanides will chemically react with the sanitizing action of the silver ions. This will eliminate their beneficial sanitizing effect.
DOS AND DON’TS
• DO check your MPS or dichlor chemical level prior to each use.
• DO change the Monarch silver cartridge every 4 months
• DO test Total Alkalinity and pH weekly.
• DO check your sanitizer prior to each use.
• DO use Monopersulfate (MPS) chlorine-free oxidizer for spas only.
• DO store all chemicals in a tightly sealed container in a cool, dry place.
• DON’T use bromine, sodium bromide or biguanides. These are an active sanitizer and will combine with the silver
ions to inactivate them.
• DON’T use a water clarifier; Clarifiers will cause the spa water to become cloudy.
CHLORINE (SODIUM DICHLOR)
A. Sanitizing chemicals, such as chlorine, are oxidants that kill bacteria and viruses in the water. The Free Available Chlorine
(FAC) is a measure of the amount of spa. unused chlorine available to sanitize the spa. The recommended FAC for your spa
water is 3.0-5.0 ppm.
B. Watkins® Manufacturing Corporation recommends the use of sodium dichlor type granated chlorine for sanitizing the water.
Sodium dichlor is preferred because it is totally soluble, dissolves quickly and is nearly pH neutral.
C. Maintaining the proper level of chlorine during use is extremely important.
D. If the FAC is too low, bacteria and viruses can grow rapidly in the warm water. Increase the FAC by adding granulated
sodium dichlor.
E. If the FAC is too high, the water can cause discomfort to the user’s eyes, lungs and skin. Simply allow some time to pass. The FAC level will drop naturally over
time.
F. When the Free Available Chlorine is within the recommended range, the spa is ready to be enjoyed.
WARNING: There are several forms of stabilized chlorine available for use in spas and swimming pools and each form has specific chemical characteristics. It is
extremely important that the one you choose is specifically designed for use in spas. Use of an incorrect product such as tri-chlor, which has a very low pH (2.6),
dissolves too quickly in hot water resulting in extremely high levels of chlorine, and is designed for concrete or plaster swimming pools, WILL cause damage to your
Use of a liquid, or any type of compressed bromine or chlorine, acid or any type or sanitizer which is not recommended by Watkins® Manufacturing Corporation WILL
damage your spa and is specifically not covered under the terms of the limited warranty.
IMPORTANT: Granulated chlorine (sodium dichlor) will degrade if stored improperly. We recommend purchasing chlorine in one, two, or five pound containers and
storing it in a cool, dry place to maintain its potency.
SUPER CHLORINATION
16
Download from Www.Somanuals.com. All Manuals Search And Download.
WATER QUALITY AND MAINTENANCE
Super Chlorination is designed to “burn-off” the build-up of chloramines (used chlorine), to eliminate the chlorine smell and to allow the proper level of free chlorine to
be maintained.
When giving your water a super chlorination treatment, open the cover at least half way for twenty minutes to allow the chlorine gas to vent off. The high
concentration of chlorine gas which may exist as a result of super chlorination (not daily sanitation) may eventually cause discoloration or degradation to
the bottom of the cover, which would not be covered under the terms of your warranty.
IMPORTANT: Always allow the Free Available Chlorine to fall below 5 ppm before using the spa.
WARNING: Never leave an open spa unattended, especially if there are children present!
BUILDING A SANITIZER ROUTINE
During the first month of ownership, measure the sanitizer residual daily in order to establish standards for User Load and Usage Time versus Sanitizer
Needed.
• The User Load of the spa is the number of times anyone enters the spa.
• The Usage Time is simply the amount of time a user spends in the spa.
• Sanitizer Needed is the amount of Free Available Chlorine (FAC) needed to accommodate the number of users and their combined usage time.
For example, two spa users who regularly use the spa once an evening for twenty minutes create a specific and somewhat consistent demand on the
sanitizer. During the first month of ownership, these two users can determine exactly how much sanitizer to use in order to maintain the proper residual. If,
at any time, the user load and/or usage pattern changes dramatically (invited guests), the amount and frequency of sanitizer required increases
dramatically.
The greater the usage time, or the bather load, the faster the residual value is diminished.

SUPPLEMENTAL WATER MAINTENANCE
Proper water sanitation and mineral balance (pH control) are absolutely essential for a complete spa water maintenance program. Here are three other
popular water additives that are optional:
Mineral Deposit Inhibitors
As water evaporates from your spa and new water is added, the amount of dissolved minerals will increase. (Minimize evaporation by keeping the cover
on the spa whenever possible.) The spa water may eventually become “hard” (Calcium Hardness too high) enough to damage the heater by calcifying its
surface. Proper pH control
can minimize this.
Normal soap build-up will require water replacement regularly enough that mineral deposits normally are not a problem.
Occasionally, high iron or copper content in the water may produce green or brown stains on the spa. A stain and scale inhibitor may help to reduce these
metals.
NOTE: Well water may contain high concentrations of minerals. The use of a low water volume, extra-fine pore water filter will help to remove many of the
larger particles during the filling of the spa.
Foam Inhibitors
Spa water requires changing due to the buildup of soap in the water. Typically, soap will cause the spa water to foam when the jets are used. Soap is
17

WATER QUALITY AND MAINTENANCE
introduced into the spa water from two sources: users’ bodies, which retain a soap residue after showering, and swimming apparel, which retains soap after washing.
Foam inhibitors can suppress foam, but cannot remove soap from the water. Soap is very difficult to remove from the water because soap is not oxidized by any
chemical added to the spa. Only ozone can oxidize soap.
Eventually the soap build-up in the water will be concentrated, resulting in an unclean feeling on the bather’s skin, which is impossible to remedy. When this occurs, it’s
time to drain and refill the spa. Depending on the soap input, the water should last about 4 months before needing to be drained.
MONARCH® OZONE SYSTEM (OPTIONAL)
The Monarch high output ozone system is the one of two ozone purification system approved for installation in your Caldera® spa. The Monarch ozone system utilizes
Corona Discharge (CD) technology to produce a higher concentration of ozone than is produced by competing ultraviolet light (UV) ozone systems.
The Monarch high output ozone system unit is less susceptible to the effects of freezing temperatures because it is installed in the equipment compartment. To access it
for inspection, remove the equipment compartment door to check the unit operation (this is usually done prior to disconnecting the power to the spa before draining).
Simply listen for the buzz of the transformer to verify operation of the Monarch high output ozone system.
The Monarch high output ozone system greatly enhances the quality of the spa water when used to supplement the spa owner’s regular water maintenance program.
Contrary to some information circulated throughout the pool and spa industry regarding ozone systems, ozone CANNOT be used as a single-source sanitizer, water
clarifier, anti-foamer, and mineral chelating agent. Watkins® Manufacturing Corporation recommends that a chemical maintenance program based on recognized and
documented industry standards still be followed when using an ozone purification system to assure water sanitation and the highest quality purified water.
Cleaning the Ozone Injector
On occasion, a mineral build up may clog the ozone injector, causing a lack of flow or low flow, of ozone bubbles. To prevent this, refer to the following instructions to
clean the injector:
1. Disconnect power to the spa.
2. Access the equipment compartment.
3. Locate the ozonator in the equipment compartment and unplug the ozonator from the control box.
4. Place 16 ounces of white vinegar into a container such as a cup or bucket. Place the container on the equipment compartment floor. NOTE: White vinegar will not
damage any of the spa components.
WARNING
WARNING
Nitric acid accumulates in the air lines of the ozonator and injector. Nitric acid
will cause severe chemical burns if direct skin contact is made, so always
wear protective gloves, glasses and clothing when working on the ozonator
or injector lines. To prevent inhalation or ingestion of the nitric acid, DO NOT
blow or inhale with your mouth to any of the adapters, fittings or tubing of
the ozonator or injector air lines.
5. Carefully loosen the long Norprene® tubing to the bottom of the ozonator. A liquid substance may be found inside the tubing. If a liquid substance is present,
BE CERTAIN NOT TO COME INTO CONTACT WITH THE LIQUID (SEE WARNING ABOVE).
6. Place the end of the tubing into the vinegar, making certain that the end of the tubing sits at the bottom of the container.
7. Reconnect power to the spa.
8. Run the spa until all 16 ounces of the vinegar are gone. This should allow an ample flow of vinegar to be run through the injector and clear the blockage.
9. Disconnect power to the spa.
10. Remove the empty cup or bucket.
11. Reinstall the tubing to the bottom of the ozonator.
12. Plug the ozonator into the control box.
13. Close the equipment compartment door.
14. Reconnect power to the spa.
TM
PUREWATER OZONE SYSTEM (OPTIONAL)
The PureWater ozone system operates during filter cycles to disburse ozone into the spa through an ozone jet located in the footwell of the spa. Water flow from the
ozone system should be checked periodically; small bubbles should be seen rising from the ozone jet.
DOS AND DON’TS
• DON’T use swimming pool (muriatic) acid to lower pH.
• DON’T splash pH increaser additives on the siding.
• DON’T misuse Compressed Sanitizers.

WATER QUALITY AND MAINTENANCE
The use of bromine sticks or tablets in floaters, which may become entrapped in a lounge or cooling seat (or sink to the spa floor), have been known to cause
discoloration of or surface distress to a spa’s shell.
• DON’T use a floater type sanitization system as a low or no maintenance solution to your spa maintenance program.
The spa shell can easily withstand the effects of a properly administered sanitizer. Floating dispensers can become trapped in one area and cause an over-sanitization
(or chemical burn) of that particular area.
If the dispenser setting is too high, the high concentration can discolor the spa shell and damage the underside of the cover.
Automatic floating dispensers have a tendency to either over-brominate or under-brominate as the rate of erosion varies greatly. Damage to the spa and cover can occur
very quickly.
WARNING: Watkins® Manufacturing Corporation does not recommend the use of any floating chemical dispenser. Damage to the spa shell or components caused
by a floating chemical dispenser is specifically not covered under the terms of the limited warranty.
• DON’T use a sanitizer which is not designed for spas.
• DON’T use household bleach (liquid sodium hypochlorite).
• DON’T broadcast or sprinkle the chemicals onto the water surface. This method may cause chemically-induced spa surface blistering (chemical abuse).
• DO add all chemicals slowly into the filter compartment with the jet pump operating for ten minutes.
• DO use special care if using baking soda to clean either the interior or exterior plastic surfaces.
• DO use only a granular form of sanitizer (chlorine).
COMMON WATER CHEMISTRY QUESTIONS
Question: Why is the use a floater not recommended to sanitize my spa water?
Answer: Watkins® Manufacturing Corporation does not recommend the use of a floater for three reasons:
1. The floater is unable to control the rate at which the sanitizer is dissolved into the water. When a floater is first placed in a spa, the sanitizer level can be extremely
high. High sanitizer levels can chemically burn or discolor the spa’s shell or the underside of the cover. Then, after a period of time, the sanitizer level dispensed by
the floater will fall to near zero. A low sanitizer level will allow viruses, bacteria or algae to grow.
2. Floaters tend to stay in one area of the spa most of the time (usually over the cool down seat), causing this area to be exposed to extreme sanitizer levels.
3. The floater may allow pieces of the highly concentrated sanitizer to fall out and settle on the floor or seat of the spa shell. These pieces of sanitizer will chemically
burn (blister) the spa shell. Although your spa shell is specifically designed to resist the effects of spa chemicals, no spa surface can withstand this type of highly
concentrated chemical. Remember, chemical abuse is specifically not covered under the terms of the warranty.
Question: When I open my spa, I smell chlorine. How do I get rid of this smell?
Answer: There are two types of chlorine in your spa. The first is the Free Available Chlorine, which is the chlorine available to sanitize your spa. This free Available
Chlorine does not have an odor. The second is Chloramine, which is residue from chlorine already expended. Chloramines have a strong chlorine odor. The smell from
Chloramines can be eliminated by “shocking” the water. If you smell chlorine in the water, your spa is reminding you to add a shock treatment.
Question: Why can’t I fill my spa with soft water?
Answer: Soft water is essentially the same as regular water except that most or all of the calcium has been replaced by sodium. Soft water may be corrosive to the
heater and other components. Replacement of spa components damaged by soft water is extremely expensive.
Question: I am trying to reduce the number of chemicals to which my family is exposed. Do I really need to use so many chemicals and in such large amounts?
Answer: While over-exposure to any chemical can be unhealthful, many low levels of chemicals are effective and beneficial. In the case of spa water, the chemicals
recommended in the Caldera® Spa Water Maintenance program are needed to protect the user from water-borne pathogens (disease-causing microbes) and to prevent
corrosion of spa components.
Question: Why isn’t water chemistry damage covered by the warranty?
Answer: The chemical levels and water quality of the water in the spa are under your direct control. With proper basic care, the spa will provide many years of hot water
relaxation. If you are unsure about any chemical or its usage in the spa, contact your Authorized Caldera dealer or Watkins® Manufacturing Corporation.
WATER TERMINOLOGY
The following chemical terms are used in this Water Quality and Maintenance section. Understanding their meaning will help you to better understand the water
maintenance process.
Bromamines: Compounds formed when bromine combines with nitrogen from body oils, urine, perspiration, etc. Unlike chloramines, bromamines have no pungent
odor and are effective sanitizers.
Bromine: A halogen sanitizer (in the same chemical family as chlorine). Bromine is commonly used in stick, tablet, or granular form. See the DO’s and DON’Ts of Spa
Water Maintenance for additional information.
Calcium Hardness: The amount of dissolved calcium in the spa water. This should be approximately 150-200 ppm. High levels of calcium can cause cloudy water and
scaling. Low levels can cause harm to the spa equipment.
Chloramines: Compounds formed when chlorine combines with nitrogen from body oils, urine, perspiration, etc. Chloramines can cause eye irritation as well as having
a strong odor. Unlike bromamines, chloramines are weaker, slower sanitizers.

WATER QUALITY AND MAINTENANCE
Chlorine: An efficient sanitizing chemical for spas. Watkins® Manufacturing Corporation recommends the use of sodium dichlor-type granulated chlorine. This type is
preferred because it is totally soluble and nearly pH neutral.
Chlorine (or Bromine) Residual: The amount of chlorine or bromine remaining after chlorine or bromine demand has been satisfied. The residual is, therefore, the
amount of sanitizer which is chemically available to kill bacteria, viruses and algae.
Corrosion: The gradual wearing away of metal spa parts, usually caused by chemical action. Generally, corrosion is caused by low pH or by water with levels of TA, CH,
pH or sanitizer which are outside the recommended ranges.
DPD: The preferred reagent used in test kits to measure the Free Available Chlorine.
Halogen: Any one of these five elements: fluorine, chlorine, bromine, iodine, and astatine.
MPS: Monopersulfate is a non-chlorine oxidizer.
Oxidizer: The use of an oxidizing chemical is to prevent the buildup of contaminants, maximize sanitizer efficiency, minimize combined chlorine and improve water clarity.
Pathogen: A microorganism such as bacterium that cause disease.
pH: The measure of the spa water’s acidity and alkalinity. The recommended pH for the spa water is 7.4 to 7.6. Below 7.0 (considered neutral), the spa water is too
acidic and can damage the heating system. Above 7.8, the water is too alkaline and can result in cloudy water, and scale formation on the shell and heater.
ppm: The abbreviation of “parts per million”, the standard measurement of chemical concentration in water. Identical to mg/l (milligrams per liter).
Reagent: A chemical material in liquid, powder, or tablet form for use in chemical testing.
Sanitizer: Sanitizers are added and maintained at recommended residuals to protect bathers against pathogenic organisms which can cause disease and infection in
spa water.
Scale: Rough calcium-bearing deposits that can coat spa surfaces, heaters, plumbing lines and clog filters. Generally, scaling is caused by mineral content combined
with high pH. Additionally, scale forms more readily at higher water temperatures.
Shock Treatment: Also known as “super-chlorination” when chlorine is used. Shock treatment is a process of adding significant doses of a quick dissolving sanitizer
(sodium dichlor is recommended) to oxidize non-filterable organic waste and to remove chloramines and bromamines.
Total Alkalinity: The amount of bicarbonates, carbonates, and hydroxides present in spa water. Proper total alkalinity is important for pH control. If the TA is too high,
the pH is difficult to adjust. If the TA is too low, the pH will be difficult to hold at the proper level. The desired range of TA in spa water is 125 to 150 ppm.

FILTER MAINTENANCE
At least once a week, check and clean the skimmer basket and weir to ensure proper filter flow. Remove leaves, foreign matter, and debris. It is very important to keep
your spa filter cartridge clean and free of particles to ensure proper water flow. A clean filter permits the hydrotherapy system to function properly and also allows more
efficient filter cycles. Depending on how frequently your spa is used, we recommend cleaning the spa filter cartridge every four weeks. If this is not done, the filter may
clog and restrict water flow, which causes improper filtration and poor jet performance.
WARNING: The frequency and duration of use, and the number of occupants all contribute to determining the appropriate time between filter cleanings. More use
means that more frequent filter cleanings will be required.
FILTER CARTRIDGE REMOVAL AND CLEANING
Turn the power to the spa OFF, then proceed as follows:
1. Push down slightly and turn filter basket counterclockwise to unlock, then pull the basket and weir out.
2. Carefully pull up the filter cartridge and bring it out of the spa.
3. Rinse cartridge using a garden hose. Rotate and separate filter pleats while spraying water to remove all debris possible. Let the filter dry and then look for calcium
deposits (scaling) or an oil film. If you find these, you will need to deep clean your filter cartridge with a “spa filter cleaning” solution to break down and remove
mineral deposits and oils.
4. Install filter then replace basket and weir by inserting and rotating clockwise to lock into position.
CARE OF THE SPA PILLOWS
Spa pillows will provide years of comfort if treated with care. They have been positioned above the water level to minimize the bleaching effects of chlorinated water and
other spa water chemicals. To extend their life, whenever the spa shell is being cleaned, the spa pillows should be removed and cleaned. Body oils can be removed with
a mild soap and water solution. ALWAYS rinse off the spa pillows thoroughly to remove any soap residue. If the spa is not going to be used for a long period of time
(that is during a vacation or if the spa is winterized), or when the spa water is being super-chlorinated, the spa pillows should be removed until the next use of the spa.
To remove and replace the spa pillows:
1. Carefully lift one end of the pillow away from the spa shell.
2. Continue lifting one end until all pillow retainers are released from the pillow.
IMPORTANT: Just pulling the pillow straight up and out of the shell recess will eventually damage the pillow. This abuse is not covered under warranty.
3. To reinstall the spa pillow, carefully bend the pillow slightly to allow one of the pillow retainers to slip into the recess in the back of the pillow.
4. Keeping the pillow slightly bent, slide the other pillow retainer into the recess in the back of the pillow.
5. After all the pillow retainers are in place, press the pillow down into the recess in the spa shell.

MAINTENANCE
DIVERTER VALVE MAINTENANCE
If your spa’s diverter valves become difficult to turn, it is likely that sand or grit has become lodged inside the valve body. It is very important that this debris is removed
as soon as possible to avoid damage to the valve. To accomplish this, follow this procedure:
1. Turn off power to the spa.
2. Remove the diverter valve’s handle by pulling upward while rocking it back and forth.
3. Unscrew the cap ring.
4. Remove the valve body by pulling it upward.
5. Wipe the valve body and the interior walls of the valve clean.
6. Lubricate the o-rings with a waterproof lubricant available from your Caldera dealer.
7. Reassemble the valve and turn on power to the spa.
CARE OF THE EXTERIOR
SPA SHELL
Your Caldera® spa has a granite-like or smooth acrylic shell. Stains and dirt generally will not adhere to your spa’s surface. A soft rag or a nylon scrubber should easily
remove most dirt. Most household chemicals are harmful to your spa’s shell. Watkins® Manufacturing Corp. recommends Soft Scrub® and Windex®. These are the only
products which have passed the manufacturer’s tests. Sodium bicarbonate (baking soda) can also be used for minor surface cleaning. Always thoroughly rinse off any
spa shell cleaning agent with fresh water.
SERVICE NOTES:
1. Iron and copper in the water can stain the spa shell if allowed to go unchecked. Ask your Caldera dealer for a stain and scale Inhibitor to use if your spa water has a
high concentration of dissolved minerals.
2. The use of alcohol or any household cleaners other than those listed to clean the spa shell surface is NOT recommended. DO NOT use any cleaning products
containing abrasives or solvents since they may damage the shell surface. NEVER USE HARSH CHEMICALS! Damage to the shell by the use of harsh chemicals
is not covered under the warranty.
IMPORTANT: Some surface cleaners contain eye and skin irritants. Keep all cleaners out of the reach of children and use care when applying.
CARE OF THE SPA COVER
WARNING: The cover is a manual safety cover that meets or exceeds all prevailing requirements of ASTM Standards for spa safety covers when installed and used
correctly as of the date of manufacture. Non-secured or improperly secured covers are a hazard. Open the cover to its fully open position before use.
VINYL COVER
The vinyl spa cover is an attractive, durable foam insulation product. Monthly cleaning and conditioning are recommended to maintain its beauty.
To clean and condition the vinyl cover:
1. Remove the cover from the spa and gently lean it against a wall or fence.
2. With a garden hose, spray the cover to loosen and rinse away dirt or debris.
3. Using a large sponge and/or a soft bristle brush, and using a very mild soap solution (1 teaspoon dishwashing liquid with 2 gallons of water) or baking soda (sodium
bicarbonate), scrub the vinyl top in a circular motion. Do not let the vinyl dry with a soap film on it before it can be rinsed clean.
4. Scrub the cover’s perimeter and side flaps. Rinse clean with water.
5. Rinse off the underside of the cover with water only (use no soap), and wipe it clean with a dry rag.
SERVICE NOTE: To remove tree sap, use cigarette lighter fluid (not charcoal lighter fluid). Use sparingly, and rinse with a saddle soap solution immediately
afterwards, then wipe dry.
Important reminders:
• DO remove snow buildup to avoid breakage of the foam core from the additional weight of the snow.
• DO lock cover lock straps to secure the cover when the spa is not in use.
• DO NOT drag or lift the spa cover using either the flaps or the cover lock straps.
• DO NOT walk, stand, or sit on the cover.
• DO NOT place any metal or heat transferring object on the cover or place any type of plastic tarp or drop cloth over the cover as this may result in a melted
foam core, which would not be covered under the warranty.
• DO NOT use any lifting mechanisms, chemicals or cleaners except those recommended by Watkins® Manufacturing Corporation or its Authorized Sales and
Service Dealer

WOOD SPA CABINET STANDARD (OPTIONAL ON OLYMPIA &
CUMBERLAND®)
The spa cabinet on Highland series spas is constructed of high-quality wood. The wood cabinet is factory-sealed with a lightly tinted stain for beauty and protection. As
with all wood products, prolonged exposure will cause discoloration and drying. Do not use wood sealers or wood furniture-type oils such as tung, teak or lemon to seal
the cabinet, as they will cause the wood to blacken. Discoloration or aging of the redwood cabinet is considered natural and is not covered by the limited warranty.
NOTE: Always test a small area (such as one or two vertical corner boards) of your spa cabinet for stain compatibility before applying a non-recommended stain.
ECOTECH® SPA CABINET (OPTIONAL ON OLYMPIA &

TM
CUMBERLAND AND STANDARD ON AVENTINE )
The EcoTech cabinet consists of rigid polymers that combine the durability of plastic, with the beauty of wood. EcoTech won’t crack, peel, blister, or delaminate even
after prolonged exposure to the elements.
Cleaning your EcoTech cabinet is as easy as spraying the cabinet with a mild soap and
water solution to remove any stains and residue.
DRAIN CAP
DRAINING YOUR SPA
1. TURN OFF OR DISCONNECT POWER FROM THE SPA.

6. After your spa is empty, clean the shell and filter cartridge.
7. After cleaning, remove garden hose and put drain cap back in place.
8. Replace the equipment compartment access door.
NON-OPERATION IN COLD CLIMATE
If the spa is to be left unused for an extended period of time in areas where FREEZING
PUMP DOOR
TEMPERATURES DO NOT OCCUR, it may be desirable to turn the heater to the lowest
temperature. The automatic filter cycles will keep the spa water clean and sparkling. When
GARDEN HOSE
preparing the spa for use, check the water chemistry to assure correct chlorine or bromine
and pH levels.
You can keep the water in the spa during the time of year when freezing at the spa location may occur. If a freeze condition is detected, the pump and heater will be
activated automatically to circulate the water in low speed. However, CAUTION must be used with this approach. In the event of electrical power interruption, regardless
of the cause, the heater and pump will stop operating and freeze protection will be lost, possibly resulting in freeze damage to the spa, spa plumbing and/or
components. Such damage is not covered by warranty.

MAINTENANCE
NOTE: When removing the water from jet openings, you may notice suction coming from another jet. With the help of a second person, block off any suction from
the other jet using a large rag or cloth. This will help pull out the water that is trapped deep inside the main line.
4. Thoroughly dry the spa shell with a clean towel.
5. Pour Propylene glycol anti-freeze into the filter suction fitttings and jet outlets. Add enough anti-freeze until the liquid starts to come out of the bottom drain.
CAUTION: Use only Propylene glycol as your anti-freeze. This is non-toxic. NEVER use automobile anti-freeze since it is toxic.
6. Close the spa cover and fasten the cover tie downs. If your area recieves a lot of snow or ice, it is recommended to cover the spa cover with two pieces of
plywood forming a pitched roof top to prevent snow and ice build-up. Secure a plastic sheet or tarp over the spa cover and one over the plywood.
WARNING: When not in use, the spa must be covered with an insulating spa cover. Damage caused by either sun exposure or freezing is not covered under
warranty.
7. In the pump side of the equipment control bay, remove the pump drain plug located on the front of the pump housings. Allow all water to drain out. Place the drain
plug in a ziplock bag and store near the pump. Replace the drain plugs on start-up. (Refer to the Figure above)
8. Unscrew the suction/discharge pump and heater unions and allow the water to drain. Leave union loose. NOTE: Tighten unions before filling spa.
9. Replace the equipment and pump doors and secure with screws.

Priming the pump(s): Upon filling or refilling the spa, if a pump is operating and water is not flowing from any of its jets, the pump may not be
properly primed. To correct, perform the following procedures:
• Turn off power to the spa at the breaker and remove the equipment compartment door (as seen on page 24).
• Loosen the union on the top of the pump(s) (as seen on page 24) to allow the air to escape, the hand-tighten the union(s).
• Turn power back on, activate the pump and check to make sure union is tight enough to keep it from leaking. Re-install pump and equipment
doors.
