Important Safety Instructions
WARNING:
To reduce the risk of drowning, electric shock, or serious injury, read the fol-
lowing important precautions before using the hydrotherapy spa.
READ AND FOLLOW ALL INSTRUCTIONS
1. It is the responsibility of the owner to ensure
that all users of the hydrotherapy spa are
adequately informed of all precautions.
10. Never insert any object into any opening.
11. Do not use breakable containers in or near
the hydrotherapy spa.
2. Use the hydrotherapy spa only as described
in this manual.
12. Do not sit on the spa cover or place objects
on it; it is not designed to support weight.
3. The hydrotherapy spa is intended for home
use only. Do not use the spa in a commercial,
rental, or institutional setting.
13. Remove any water or debris that may collect
on the spa cover.
14. Keep children under the age of 12 and pets
away from the hydrotherapy spa when it is
not in use.
4. Use the hydrotherapy spa only on a level sur-
face. Do not use the spa on carpet or other
materials that could be damaged by moisture.
15. Keep all chemicals away from children and
pets.
5. The hydrotherapy spa will weigh approxi-
mately 3,300 pounds when it is filled with
water. Make sure that the location you select
for the spa will support this weight, plus the
weight of the occupants.
16. The pH and chemical balance of the water
must be maintained as explained in this man-
ual (see pages 10 and 14). Failure to do so
may cause injury to users or damage to the
hydrotherapy spa, and will void the warranty.
6. Inspect and tighten all parts regularly.
Replace any worn parts immediately.
17. Individuals with infections and open sores or
wounds should not use the hydrotherapy
spa. Bacteria thrive in warm and hot water.
Always keep your spa disinfected and main-
tain the proper chemical balance.
7. DANGER—Risk of injury: Do not remove or
alter the covers on the suction fittings. Never
operate the hydrotherapy spa if the suction
guard is missing or broken. If you need to
replace a suction fitting or pump, make sure
you use only manufacturer recommended
replacement parts. Keep hair and body parts
away from the suction guard. Do not allow
long hair to float freely in the water; long hair
should be restrained with a bathing cap.
18. Shower before and after using the hydrother-
apy spa. This will remove any deodorant, per-
spiration, or body oils that could contaminate
the water. Showering after will remove any
residual chemicals and any bacteria that may
have been in the spa.
8. IMPORTANT: Do not allow the hydrotherapy
spa to be exposed to direct sunlight when it
is empty. The surface of the spa shell can
reach temperatures as high as 150°F in a mat-
ter of minutes if exposed to the sun while it is
empty. These high temperatures can cause
significant damage, such as blistering of the
shell surface and warping of the spa shell.
Any damage caused by sun exposure is not
covered under the warranty.
19. WARNING—The Ground Fault Circuit
Interrupter (GFCI), must be tested before
each use. To test the GFCI, press the “test”
button while the hydrotherapy spa is running.
The spa should shut off. Press the “reset”
button. The spa should resume normal opera-
tion. If the spa continues to run after the
“test” button is pressed, then the GFCI is
damaged. Do not use the spa until the GFCI
has been repaired or replaced by a qualified
electrician.
9. Do not bring any object into the hydrotherapy
spa that could damage the spa shell.

electrical appliances such as radios, tele-
phones, televisions, and lights at least five
feet away from the water.
physician before using the hydrotherapy spa.
Pregnant women should not use the spa if
the water temperature is above 100°F; the
unborn child could be seriously harmed. This
is especially important during the first 90
days of the pregnancy.
21. A wire connector is provided on the electron-
ics pack of the hydrotherapy spa to connect a
minimum No. 6 AWG (13.3 mm2) solid copper
conductor between the spa and any metal
equipment, electrical enclosure made of
metal, metal water pipes, or conduit within
five feet of the spa.
29. DANGER—To reduce the risk of drowning:
Prolonged immersion in the hydrotherapy spa
may cause hyperthermia. The causes, symp-
toms and effects of hyperthermia may be
described as follows: Hyperthermia occurs
when the internal temperature of the body
reaches a level several degrees above the
normal body temperature of 98.6°F. The symp-
toms of hyperthermia include an increase in
the internal temperature of the body, dizzi-
ness, lethargy, drowsiness and fainting. The
effects of hyperthermia include failure to per-
ceive heat; failure to recognize the need to
exit the spa or hot tub; unawareness of
impending hazard; fetal damage in pregnant
women; physical inability to exit the spa or
hot tub and unconsciousness resulting in
danger of drowning. WARNING: The use of
alcohol, drugs or medication can greatly
increase the risk of fatal hyperthermia.
22. DANGER—Risk of electric shock: Do not set
the hydrotherapy spa within five feet of any
metal objects or surfaces. As an alternative,
you may use the spa within five feet of metal
objects if each metal object is permanently
connected to the wire connector on the elec-
tronics pack of the spa by a minimum No. 6
AWG (13.3 mm2) solid copper conductor (see
instruction 21).
23. Do not operate the pump motor when the
hydrotherapy spa is empty. The pump motor
may be seriously damaged if it is operated
without water circulating.
24. DANGER—Risk of drowning: Exercise
extreme caution to prevent unauthorized and
unsupervised use of the hydrotherapy spa by
children. Children must always be supervised.
30. WARNING—To reduce the risk of drowning:
Do not use the hydrotherapy spa if you are
under the influence of alcohol or drugs. Heat
from the water, in conjunction with alcohol or
drugs, can cause loss of consciousness.
25. DANGER—To reduce the risk of drowning:
• Never use the hydrotherapy spa alone.
• Children should not use the spa unless they
are supervised by an adult.
31. WARNING—To reduce the risk of injury or
drowning: Consult your physician about pos-
sible side-effects of any medications you may
be taking before using the hydrotherapy spa.
Heat from the water, in conjunction with some
medications, may cause drowsiness and
increase the risk of drowning. Other medica-
tions can effect blood pressure, heart rate,
and circulation.
• Keep pets away from the spa at all times.
• Always replace and lock the spa cover when
the spa is not in use.
26. WARNING—To reduce the risk of injury: The
water temperature should never exceed
104°F. Temperatures between 100°F and 104°F
are considered to be safe for healthy adults.
However, if you plan to remain in the hydro-
therapy spa for more than 10 to 15 minutes, a
lower temperature is recommended. Lower
temperatures are also recommended for chil-
dren. Children should not be allowed to swim
under the surface of the water in the spa.
32. Do not use the hydrotherapy spa immediately
after strenuous exercise.
33. If you feel pain or dizziness at any time while
using the hydrotherapy spa, discontinue use
and contact a physician.
34. WARNING—To reduce the risk of injury: It is
especially important for persons over the age
of 35 or persons with pre-existing health
problems, such as obesity, heart disease,
high or low blood pressure, circulatory prob-
lems, or diabetes to consult their physician
before using the hydrotherapy spa.
27. WARNING—To reduce the risk of injury:
Before entering the hydrotherapy spa, always
use an accurate thermometer to determine
the water temperature.

Choosing a Location for the Hydrotherapy Spa
There are many factors to consider when choosing a location to set up the hydrotherapy spa. These factors vary
depending on whether you plan to use the spa inside or outside. We have listed several factors you may wish to
consider as you decide where to set up the spa.
If you set up the hydrotherapy spa inside:
If you set up the hydrotherapy spa outside:
1. The spa will increase the level of humidity in your
home. The location you choose should be well
ventilated. You may need to install a ventilation fan
or use a dehumidifier.
1. Check local building codes concerning the use of
outdoor spas.
2. The spa should be located near a 240-volt power
source. It must be wired directly into a grounded
circuit with a Ground Fault Circuit Interrupter
(GFCI) capable of carrying 40 amps. No other
appliance should be on the same circuit.

Using the Hydrotherapy Spa
The hydrotherapy spa is designed to seat seven
adults. The spa holds approximately 375 gallons of
water and offers a heating system (80°F to 104°F), a
filtration system, and adjustable hydrotherapy jets.
Follow the guidelines below to use and maintain the
spa for your long-term enjoyment.
Once you have tested the GFCI, you should verify the
water flow from the pumping unit. Set the air control
on the console to the lowest setting (see USING THE
CONTROLS on page 12). The pumping unit will heat
the water as it pumps. Cover the hydrotherapy spa
with the spa cover. The spa cover must be tight
(see SECURING THE SPA COVER ON THE SPA on
this page). The water will heat at about 6°F per hour
with the cover on. If you are using the spa indoors,
and the room temperature is maintained at 70°F, it will
take approximately 6 to 8 hours for the water to reach
the set temperature.
WIRING THE HYDROTHERAPY SPA
The hydrotherapy spa is designed to operate with a
240-volt power source. It must be wired directly into a
grounded circuit with a Ground Fault Circuit
Interrupter (GFCI) capable of carrying 40 amps. No
other appliance should be on the same circuit.
Connection of the spa to the 240-volt power
source must be performed by a qualified, licensed
electrician and must comply with all local, state,
and federal electrical codes. Please refer to the
instructions on the inside of the electronics package
for information about connecting the spa to a 240-volt
power source.
The temperature and the water flow can be set or
changed with the controls on the console (see USING
THE CONTROLS on page 12).

WATER CHEMISTRY
The maintenance of the pH level is very important to
the operation of the spa. To maintain the proper pH
level and to sanitize the spa, you can purchase a
chemical starter kit from your local pool and spa sup-
ply store.
MAINTAINING THE SPA EXTERIOR
The premium cedar surround has been treated at the
factory. For information and supplies to maintain the
beauty and color of the premium cedar surround, con-
tact your local pool and spa supply store.
CAUTION: The chemicals used to maintain the pH
balance of the water and to sanitize the water can
be dangerous. Always follow these basic guide-
lines when handling the chemicals:
CLEANING THE SPA SHELL
1. Always read and follow the directions on the
label, unless directed otherwise.
The spa shell should be cleaned with a mild soap
solution; do not use solvents. The spa should always
be clean and dry before being moved or stored.
2. Never mix different chemicals.
3. Do not exceed the recommended amounts of
chemicals—follow the directions on the label
closely.
MAINTAINING THE SPA COVER
4. Keep all chemicals out of the reach of children
and pets.
The spa cover should be cleaned monthly. To clean
the spa cover, use water and a non-abrasive cleaner
on the entire cover. Rinse the cover with a garden
hose to remove any cleaner residue. Dry the cover
5. Keep containers closed tightly when not in use.
6. Never add water to the chemicals—always add
the chemicals to the water as directed.
7. Always store chemicals in a cool, dry place.

MAINTAINING THE PROPER PH BALANCE
REMOVING AND ATTACHING THE ACCESS PANEL
The pH factor is a measure of the relative acidity or
alkalinity in the water, and is measured on a scale of
1 to 14. Pure water has a value of 7, which is neutral.
Any value above 7 is alkaline, and any value below 7
is acidic. You should maintain a slightly alkaline pH
level, between 7.2 and 7.8, in the hydrotherapy spa.
To locate the access panel, refer to the drawing on
page 6. Turn off the power to the spa. To remove the
access panel, first remove the four indicated screws.
Slide the access panel down and then pull the bottom
of it away from the spa. Note: Be careful not to
damage the spa shell as you remove the access
panel.
Severe problems can occur when the pH balance is
not maintained within this range. If the pH level
exceeds 7.8, dissolved minerals can build up and clog
the plumbing in the spa jet unit. If the pH level falls
below 7.2, the acid level in the water will begin to cor-
rode the metal parts in the spa jet unit. Also, the sani-
tation agents in the water will not be effective if the pH
level is not properly maintained. Damage caused by
improper pH levels is not covered under the warranty.
46
To maintain the proper pH level, test the pH of the
water regularly. To test the water, purchase a pH test
kit at a pool and spa supply store. The pH reading
should be between 7.2 and 7.8. If the level is too low,
add a pH increaser (usually soda ash). If the level is
too high, add a pH reducer (usually sodium bisulfate).
Test the water again after five minutes. See the
instructions with your pH test kit for additional infor-
mation about testing and adjusting the pH.

To re-attach the access panel, insert the top of the
access panel under the edge of the spa shell. Slide
the access panel up until the bottom of the access
panel clears the trim along the bottom of the spa.
Then, slide the access panel into place and re-attach
the four screws.
SANITIZING THE HYDROTHERAPY SPA
The most common sanitizing agent is a solid bromine
concentrate. The amount required varies according to
several factors, such as user load, temperature, and
water conditions. Proper water maintenance is a com-
plex process. Contact your local pool and spa store
for information concerning which chemicals you
should use in your area to sanitize the spa.
DRAINING THE HYDROTHERAPY SPA
The hydrotherapy spa should be drained at least four
times per year and refilled with clean water. You may
need to drain the spa more often, depending on the
user load. This must be done because after repeated
chemical treatment the water becomes chemically
saturated. Once this happens, additional chemical
treatment of the water is no longer effective. The spa
should also be drained if you will not be using it for
long periods of time. The spa must always be drained
before major repairs are made.
CHANGING THE FILTER CYCLE
The spa will filter the water every 12 hours. The dura-
tion of the cycle can be adjusted to last 2 to 5 hours.
Press the temperature up or temperature down button
on the console. When the display begins to flash,
press the pump button. The display will read F2. To
change the time, press the temp up button until the
desired time is reached. Press the pump button to
confirm the selection. As spa usage increases, the
duration of the filter cycle may need to be increased.
The hydrotherapy spa should always be covered
when it is empty. Direct sunlight can cause exten-
sive damage. The surface of the spa shell can
reach temperatures as high as 150°F in a matter
of minutes if exposed to the sun while it is empty.
These high temperatures can cause significant
damage, such as blistering of the shell surface
and warping of the spa shell. Any damage caused
by sun exposure is not covered under warranty.

To drain the hydrotherapy spa, follow the steps below:
WINTER USE AND CARE
1. Using the console, adjust the temperature to the
lowest setting.
The hydrotherapy spa is designed for year-round use.
If you decide to store the spa for the winter, store it in
2. Shut off the power to the spa, at the circuit breaker a warm, dry location. Follow the steps below to winter-
or GFCI.

3. Remove the access panel from the spa (see
ATTACHING AND REMOVING THE ACCESS
PANEL on page 14).
4. Pull the hose out and hold it above the waterline.
Remove the cap, open the valve knob, and attach
a garden hose to the drain hose. Lower the hose
and drain the spa.
1. Make sure the power to the spa is turned off.
2. Drain the spa (see DRAINING THE HYDROTHER-
APY SPA on the previous page and this page).
3. Remove all remaining water from the spa shell. Dry
the spa shell with towels.
4. Set the air controls to the lowest setting. Use a
wet/dry vacuum to pull any remaining water from
the system. To do this, place the vacuum nozzle
over each jet, starting with the highest jet and fin-
ishing with the lowest jet.
5. Set the air controls to the highest setting and
repeat step 3.
6. Drain the pumps (see DRAINING THE PUMPS on
this page). Once the water is drained from the
pumps, place the vacuum nozzle over the drainage
hole in the pumps and vacuum any additional
water from the pumps. Note: For additional pro-
tection, remove the pumps/motors from the spa
and store them in a climate-controlled room.
7. Clean the spa shell (see page 13).
8. Clean the filters (see page 13).

Make sure the spa power is turned off. Next, locate the
light housing. Turn the light housing counterclockwise
and remove it from the spa shell.
DRAINING THE PUMPS
After the hydrotherapy spa is drained, the jet pumps
should also be drained if the spa will be stored for
more than thirty days or if it may be exposed to freez-
ing temperatures.
