Pre-Delivery and Installation  
Checklist  
Most cities and counties require permits for exterior construction and  
electrical circuits. In addition, some communities have codes requiring  
residential barriers such as fencing and/or self-closing gates on property to  
prevent unsupervised access to the property by children under the age of  
5. Your dealer can provide information on which permits may be required  
and how to obtain them prior to the delivery of your Cal Spa®.  
We strongly recommend you have a qualified, licensed contractor perform  
the installation of your in-ground or ported spa. The installation instructions  
contained in the manual are for the use of a qualified contractor or  
installer.  
Consumers who choose to install their own in-ground spas bear sole  
responsibility for any performance or warranty issues and may void portions  
of their warranty as a result. For this reason, we strongly recommend they  
hire an experienced professional for their installation.  
For additional operating and installation information, please see your  
selling dealer. To locate a dealer nearest you call 800-CALSPAS or visit

Planning the Best Location  
Safety first  
Do not place your spa within 10 feet (3 m) of overhead power lines.  
Make sure the spa is positioned so that access to the equipment  
compartment and all side panels will not be blocked. Be certain that your  
installation will meet all city and local safety codes and requirements.  
Consider how you will use your spa  
How you intend to use your spa will help you determine where you should  
position it. For example, will you use your spa for recreational or therapeutic  
purposes? If your spa is mainly used for family recreation, be sure to leave  
plenty of room around it for activity. If you will use it for relaxation and  
therapy, you’ll probably want to create a specific mood around it.  
Plan for your environment  
If you live in a region where it snows in the winter or rains frequently, place  
the spa near a house entry. By doing this, you will have a place to change  
clothes and not be uncomfortable.  
Consider your privacy  
In a cold-weather climate, bare trees won’t provide much privacy. Think of  
your spa’s surroundings during all seasons to determine your best privacy  
options. Consider the view of your neighbors as well when you plan the  
location of your spa.  
Provide a view with your spa  
Think about the direction you will be facing when sitting in your spa. Do  
you have a special landscaped area in your yard that you find enjoyable?  
Perhaps there is an area that catches a soothing breeze during the day or  
a lovely sunset in the evening.  
Keep your spa clean  
Prevent dirt and contaminants from being tracked into your spa by placing  
a foot mat at the spa’s entrance where the bather’s can clean their feet  
before entering your spa. You may also consider keeping a small water-  
filled basin nearby for bathers to rinse their feet before entering your spa.  
In planning your spa’s location, consider a location where the path to and  
from the house can be kept clean and free of debris.

Allow for service access  
Many people choose to install a decorative structure around their spa. If  
you are installing your spa with any type of structure on the outside, such  
as a gazebo, remember to allow access for service. It is always best to  
design special installations so that the spa can still be accessed.  
Consider the best place for the outdoor equipment pack  
(in-ground spas only)  
The Designer Spa series requires an external equipment pack. When  
locating the outdoor equipment pack, you will want to consider the  
following:  
•
•
•
•
The equipment pack must be located within a maximum of 15 feet  
from the spa.  
Ensure the equipment running its normal filtration cycles does not  
make too much noise for spa owners and/or neighbors.  
Ensure the equipment can be easily serviced for filter cleaning and  
periodic inspections in the location chosen.  
If you are using a gas heater, you will need to consider wind and drafts  
as well as heater exhaust for proper heater placement. (See heater  
owner’s manual for important location and safety information.)  
•
•
•
The equipment base and heater must be placed on either a 3 1/2”  
cement slab or 3” paving stones.  
Make sure the equipment area selected will not be in an area where  
water could run or stand.  
If the area receives direct sunlight, you will want to provide some  
protection for the equipment portion of the equipment pack.  
The equipment pack and heater are delivered separately. Do not cover gas  
heaters unless properly vented. (See heater owner’s manual for important  
safety information.)

Portable Spa Site Preparation  
Your spa needs a solid and level foundation. The area that it sits on must  
be able to support the weight of the spa, with water and the occupants who  
use it. If the foundation is inadequate, it may shift or settle after the spa  
is in place, causing stress that could DAMAGE YOUR SPA SHELL AND  
FINISH.  
Note: Damage caused by inadequate or improper foundation support is  
not covered by the warranty. It is the responsibility of the spa owner to  
provide a proper foundation for the spa.  
Place the spa on an elevated foundation (preferably a 3” - 4” concrete  
slab). Pavers, gravel, brick, sand, timbers or dirt foundations are not  
adequate to support the spa. If you are installing the spa indoors, pay  
close attention to the flooring beneath it. Choose flooring that will not be  
damaged or stained.  
If you are installing your spa on an elevated wood deck or other structure, it  
is highly recommended that you consult a structural engineer or contractor  
to ensure the structure will support the weight of 150 pounds per square  
foot.  
To properly identify the weight of your new spa when full, remember water  
weighs 8.33 lbs. per gallon. For example, an average 8’ spa spa holds  
approximately 500 gallons of water. Using this formula, you will find that  
the weight of the water alone is 4,165 lbs. Combined with the dry weight  
of the spa you will note that this spa will weigh approximately 5,000 lbs.  
when full of water.  
Note: It is strongly recommended that a qualified, licensed contractor  
prepare the foundation for your spa.  
Your Cal Spas® retailer can help you with your foundation and more. Your  
retailer has a wealth of information and experience about how to get the  
most out of your spa and can provide you with a full line of accessories  
that are designed to complement your spa and increase your enjoyment.  
In-Ground Spa Site Preparation  
•
•
Ensure there is enough room for the spa and equipment.  
The equipment pack must be located within a maximum of 15 feet  
from the spa.  
•
•
Plan for proper electrical and gas service to both the equipment area  
and spa side.  
Ensure the required flat, level foundation can be constructed in the  
area chosen.

•
•
The spa must be properly back-filled with wet sand, underneath and  
on all four sides.  
The final architecture must include permanent ground coverage within  
a 10 feet radius of the spa.  
Never place any spa in a sealed area. Water must be able either to be  
absorbed into the surrounding area or channeled away. Water build-  
up under and/or around the spa, will cause the spa to float out of the  
ground.  
Grading Prior to Excavation  
Selection of the Designer Spas site will determine how much grading will  
have to be accomplished prior to the actual dig for the spa. Naturally, a  
level area is best because it will require the least amount of preparation for  
the dig, but in many cases there is no level area, therefore, the site must  
be prepared to accept the Spa prior to dig. The spa site should be elevated  
slightly higher than the surrounding area  
When dealing with slopes, the severity of the slope will determine if  
retaining walls must be built in order to have a level area for the spa. If the  
slope is relatively minor, contact your local building safety.  
Site Excavation – Hard Bottom  
For hard bottom placement for in-ground spas, you will need a smooth and  
flat concrete surface at least 4” thick as large as the bottom contact points.  
Be sure not to seal the bottom off and making a sealed box. You will need  
adequate water drainage for escape under the spa. A gravel beds around  
the concrete base will help with this.  
Site Excavation – Sand Bottom  
With the spa area and all elevations planned including your decided type  
of decking, you are now ready to proceed with the dig. An ideal excavation  
is one that is as close as possible to the dimensions of the spa shell, but  
with the following rules in mind. The excavation should be 2” to 4” deeper  
than the actual spa for your sand bed. The sand bed is to level the spa  
shell and provide a perfect support base with no voids when the spa is  
lowered into the hole. Your excavation should be approximately one foot  
longer and one foot wider than the spa shell. This will allow for a six inch  
over dig all the way around the spa once it is in place. Additional hand  
excavation will be required to insure the skimmer will fit in the excavation  
when attached to the spa.  
Sand or rock dust must be used to bed the shell into the excavation and  
for backfill. In no event is dirt to be used. One of the easiest ways to know  
how much sand is needed to be placed on the bottom of the excavation is  
to set a grade stake at all four corners, and one on each side of the center  
line in the bottom of the hole. If there are areas that are deeper than 2” to  
4”, these can be filled with sand and are of no consequence.

Getting the Spa Into Your Yard  
Check the Dimensions of Your New Cal Spa®  
The Cal Spas® specification chart lists your spa’s model and its dimension  
as it sits on the delivery cart. During delivery, the spa must remain on the  
delivery cart at all times. Compare the dimensions to the width of the gates,  
sidewalks, and doorways along the delivery route. It may be necessary for  
you to remove a gate or partially remove a fence in order to provide an  
unobstructed passageway to the installation location.  
Plan the Delivery Route  
Consider the following when planning your delivery route:  
•
Check the width of gates, doors and sidewalks to make sure your spa  
will pass through unobstructed. You may have to remove a gate or  
part of a fence to allow for adequate width clearance.  
•
Are there low roof eaves, overhanging branches or rain gutters that  
could be an obstruction to overhead clearance?  
•
•
8’ spas need at least 42” wide gate and 9’ height clearance.  
If the delivery route will require a 90º turn, check the measurements at  
the turn to ensure the spa will fit.

•
•
Are there protruding gas meters, water meters or A/C units on your  
home which will cause obstructions along the delivery path to your  
yard?  
Are there stairs in your delivery route? If so, you must consult your Cal  
Spas® dealer prior to delivery to make adequate preparations.  
Special Circumstances  
The use of a crane for delivery and installation may become necessary if  
you are unable to provide an adequate delivery route. It is used primarily  
to avoid injury to your spa, your property or to delivery personnel. Your Cal  
Spas® dealer may be able to assist you with the arrangements. If your spa  
delivery requires the use of a crane, the cost of a crane is generally not  
included in the standard delivery service.

Electrical Requirements  
Electrical Requirements – US and Canada  
240 Volt Electrical Installation  
All 240V spas must be permanently connected (hardwired) to the power  
supply. These instructions describe the only acceptable electrical wiring  
procedure. Spas wired in any other way will void your warranty and may  
result in serious injury.  
This is the only acceptable electrical wiring procedure. Spas wired in any  
other way will void your warranty. See the wiring diagram on page 9.  
When installed in the United States, the electrical wiring of this spa must  
meet the requirements of National Electric Code, ANSI/NFPA 70-2008 and  
any applicable local, state, and federal codes. The electrical circuit must  
be installed by an electrical contractor and approved by a local building /  
electrical inspector.  
GFCI and Wiring Requirements  
The power supplied to the spa must be on a dedicated GFCI protected  
circuit as required by ANSI/NFPA 70 with no other appliances or lights  
sharing the power.  
Use copper wire with THHN insulation. Do not use aluminum wire.

Test the GFCI breaker prior to  
first use and periodically when the  
spa is powered. To test the GFCI  
breaker follow these instructions  
(spa should be operating):  
Control System  
The 6300 control system requires  
higher power than other 240V sys-  
tems. Dip switch #10 is factory set  
in the ON position. This causes the  
heater to shut off when any pump  
is running in high speed. To allow  
the heater to continue operating,  
dip switch #10 must be set to the  
OFF position.  
1. Press the TEST button on the  
GFCI. The GFCI will trip and  
the spa will shut off.  
2. Reset the GFCI breaker by  
switching the breaker to the full  
OFF position, wait a moment,  
then turn the breaker back on.  
The spa should have power  
again.  
To ensure your spa functions prop-  
erly, ensure the following steps are  
performed before starting your spa:  
•
When installing the electrical  
system, use a 60 amp GFCI.  
Follow the GFCI wiring diagram  
on the next page.  
•

Plumbing Connections  
IMPORTANT! Always check local codes prior to any in-ground spa  
installation.  
Once the spa and equipment are properly located, you will want to lay out  
the plumbing run.  
Trenches should be deep and wide enough to allow all pipes to be buried  
below the frost line and should be in as straight a line from the spa to the  
equipment as possible. Check local code requirements for underground  
pipes. Always know what is under the ground before you dig anywhere.  
You will need 2” flex or PVC lines for your suction, intake, and air line. In  
ground spas have marked intake and suction lines, making it easy find and  
connect to and from the spa and equipment pack.  
The plumbing run should not be any longer than 15 feet to maximize  
water pressure. Another way to maximize water pressure is to limit (or  
even eliminate) the use of 90˚ elbows in your plumbing run. A more direct  
plumbing run using 45˚ elbows is more efficient, and promotes increased  
water pressure.  
Identifying Plumbing Lines  
The spa’s plumbing lines are clearly marked during water testing at the  
factory.Thisisdonetoassistinstallersinproperlyidentifyingtheinstallation.  
We still recommend that the installers verify plumbing lines prior to gluing.  
This can be done by using one of the following techniques.  
Air Test  
The air test requires a wet/dry vacuum. Locate the plumbing line you  
wish to identify and secure the vacuum hose to cut open end. Turn on the  
vacuum, enter the spa and listen for vacuum suction sound from inside the  
spa side filter canister. If you hear the suction sound in the canister, the  
line is properly marked and can be connected to the suction side of the  
pump on the equipment pack.  
Water Test  
The water test requires a garden hose and water source. Locate the  
plumbing line you wish to identify and secure the outlet side of the garden  
hose to cut open end. Turn on the water supply to the garden hose, enter  
the spa and look for water inside the spa side filter canister. If you see  
water in the canister the line is properly marked and can be connected to  
the suction side of the pump on the equipment pack.  
If any plumbing line is not properly marked or not marked at all, follow  
either the air or water test procedure until all lines are identified prior to  
gluing.

NOTE: Once complete, water test the plumbing run for at least three  
days prior to covering any plumbing trenches and back-filling spa cavity  
completely.  
NOTE: Some local inspectors require pressure testing the plumbing lines.  
Although the spa is pressure tested at the factory, local inspectors may  
insist on pressure testing the plumbing run between the spa and equipment  
pack.  
Gate/Slice Valves  
The use of gate valves is recommended on all plumbing lines (both suction  
and return lines). These valves are used to contain the spa’s water in either  
the equipment or the spa. This will assist in the pump priming process and  
future servicing without needing to drain the spa.  
NOTE: When draining the spa to perform maintenance, always close the  
gate valves prior to draining. This will maintain the pumps prime.  
Connecting Plumbing to Remote Equipment  
Connecting the plumbing from the spa to the equipment pack must be  
performed in accordance to local and city codes.  
NOTE: Most codes require plumbing to be rigid PVC schedule 40 or heavier  
in both above and below ground installations. In most cases, the use of  
flexible PVC plumbing is acceptable when properly buried in trenches.  
Most water plumbing lines are 2” or larger and must be schedule 40 or  
heavier PVC. When plumbing, minimize the use of 90˚ elbows as much as  
possible. The use of 45 ˚ elbows will increase the amount of jet pressure  
you will have over the use of 90˚ elbows.  
The plumbing on the spa shell is labeled by the factory in the following  
manner:  
Pump 1 Suction: 2” line that connects the spa filter and bottom drain  
assembly to the front of pump 1.  
Pump 1 Return: 2” line that connects the top of pump 1, through the  
equipment filter and heater back to selected jets in the spa.  
Pump 2 Suction: 2” line that connects the spa filter and bottom drain  
assembly to the front of pump 2.  
Pump 2 Return: 2” line that connects the top of pump 2 back to selected  
jets in the spa.  
Ozone Line: 1” line that connects to a 1” flexible line extending off the  
bottom of the equipment pack filter canister through an ozone injector (If  
ozone equipped) and connected to ozone port on the spa.  
Air Blower: 1 1/2” line that is plumbed out of the air blower (located on  
the equipment pack) and extended up 18” above the spas water level to  
prevent water flooding the air blower.

Air Venturi: 1/2” line that is plumbed 18” above the spa’s water level.  
Topside Control Panel and Temp Sensor: 1” line that connects to the  
bottom of the control box located on the equipment pack.  
Electrical and Electronic Connection  
Remote Equipment Topside Control Panel  
The next few steps to complete the installation should be performed  
along with installation of the temperature sensor and 12V spa light wiring  
(if applicable). All of these components are generally installed using the  
same conduit.  
1. Locate the topside control  
panel extension loom in the  
control box mounted with the  
equipment pack. This extension  
loom and attached black  
terminal connector (see figure  
at right) will be used to connect  
the topside control panel to the  
control box.  
2. Connect one end of the black  
terminalconnectortothetopside  
control panel cable.  
3. Connect the other end of the terminal connector to the extension  
loom.  
NOTE: This connection must be kept dry. We recommend that a waterproof  
junction box be used in installations where moisture could penetrate this  
terminal connector.  
4. Lay out the extension loom to verify that you have enough length to  
reach the control box. Remember that conduit runs are not generally  
run in a straight line. Every bend, and up and down run consumes  
line length. Take this into consideration when verifying electrical and  
plumbing runs.  
5. Connect the extension loom to the control panel location on the circuit  
board located inside the control box. You will also need to connect  
both the temperature and high limit sensors to the circuit board prior to  
testing. (See the temperature and high limit installation instruction on  
the next page for proper identification and see the wiring diagram on  
the inside cover of the control box for proper placement.)  
6. Turn on the power supply to the spa equipment and briefly test all  
functions on the topside control panel to verify that both connections  
and extension loom are in working order before proceeding with the  
installation.

NOTE: Circuit board programming will not allow spa operation without  
both the temperature and high limit sensors being properly connected to  
the circuit board.  
7. Once topside panel operation is verified. Turn off power, disconnect  
the extension loom from the circuit board and GENTLY route through  
conduit to complete installation.  
NOTE: This loom and its connector are not meant to withstand heavy  
pulling. Make sure, when routing the extension loom and temperature  
sensor lines through conduit, you exercise extreme caution.  
Once properly run through the conduit, repeat steps 5 and 6 above.  
In-Ground Spa Light Installation Instructions  
On spas ordered with in-ground lights, the factory installs the light niche  
for you. The next steps of installation should be performed by a qualified  
licensed electrician.  
Always read and follow light manufacturer’s safety and installation  
instructions prior to installation and operation. Incorrect installation may  
damage the light and void its warranty.  
The light circuit must be on a GFCI protected service (alone or with a  
switch).  
The water resistant junction box (or for 12 volt models, the low voltage  
transformer) must be located:  
•
•
•
at least 8” (20 cm) above water level  
at least 4” (10 cm) above ground level, and  
at least 48” (121 cm) away from the spa.  
See figure below.  
22  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Light niche and any metallic items in a 5’ (152 cm) radius must be properly  
bonded with #8 AWG grounding wire.  
1. Connect rigid conduit to the 3/4” hub located at the back of the light  
niche and run to a water resistant junction box (or for 12 volt models  
to a low voltage transformer) no further than 25’ (7.6m). Remember  
this is a water cooled light, so the conduit and all connections must be  
leakproof.  
2. Feed the light cord through the rigid conduit to the junction box, leaving  
at least 4 feet of cord at the end of the light fixture. This slack in the  
light cord will allow servicing without draining the spa in the future.  
3. Wrap light cord slack around back of light housing and attach light to  
niche with mounting screw.  
4. Cut the cord at the junction box, leaving at least 6” (15 cm) of cord to  
make connections.  
5. Strip 6” (15 cm) of the out cord jacket to expose the three insulated  
wires. Be careful not to damage the insulation on the three inner  
wires.  
6. Connect the three wires to the corresponding circuit wires in the  
junction box and secure the junction box cover in place.  
7. Replace the light assembly in the niche and tighten the special pilot  
screw.  
8. Fill the spa until the underwater light is completely submerged in water  
before operating the light for more than 10 seconds. Turn on the main  
switch or circuit breaker, as well as the spa light control, to check for  
proper operation  
Important: Make sure spa light is submerged in at least 18” of water  
prior to testing.

Pouring the Deck  
Itisrecommendedthatallelectricalhookupsandallplumbingbecompleted  
before pouring the concrete. Make certain all electrical inspections on  
lights, bonding and all other electrical work have been completed and  
checked off by the local inspectors prior to proceeding with your concrete  
or finish work. It is a good idea to run the spa for at least 24 hours before  
pouring the concrete to insure there are no leaks. We understand you  
want to enjoy your spa now, but a 24-hour period with your spa running will  
let you know of any problems before they will be extremely hard to fix.  
The type of decking you have selected will have determined the grade of  
the spa. If you are pouring a regular deck up to the spas coping, then the  
top of the coping should be 4” above the surrounding area. In either event,  
it is recommended to dig out an area around the spa exposing the flange  
of the coping and just under it. This is important, as concrete should be  
packed under and over the flange of the spa, as the deck is poured. This  
will lock the spa into the concrete and provide for a much stronger bond  
of the spa to the deck. It will also eliminate cracking of the deck where it  
meets the spa.  
When setting your outside forms, remember you want any water from rain  
or splash out to run off the deck, not into the spa. If your deck is going to tie  
into an existing deck, than some type of drain system should be planned to  
handle the run off. Proper drainage planning is very important.  
An experienced concrete finisher should always be used when pouring  
spa decks, especially when you are doing a cantilevered deck, as the  
forms must be taken off at the proper time to allow finishing of the inside  
of the form.
