Important Safety Instructions
When installing and using this electrical equipment, always follow basic safety precautions. Following these
instructions will help make your first spa session a pleasurable one.
READ AND FOLLOW ALL INSTRUCTIONS
WARNING: To reduce the risk of injury, do not allow children to use the spa unless they are supervised at all
times.
All 110V spas require a DEDICATED 20 AMP GFCI SERVICE. Do not use extension cords.
NOTE: This may require a licensed electrician to upgrade your standard receptacle and/or circuit breaker.
All 220V spas require a DEDICATED 50 AMP GFCI SERVICE WITH FOUR #6 AWG COPPER WIRES.
DANGER -- RISK OF ACCIDENTAL DROWNING: Use extreme caution to prevent unauthorized access by
children. To avoid accidents, ensure that children cannot use the spa unless they are closely supervised at all
times. (Keep the spa cover on and locked when not in use. See instructions enclosed with your cover.)
DANGER -- RISK OF INJURY: The suction fittings in this spa are sized to match the specific water flow
created by the pump. Should the need arise to replace the suction fittings, or the pump, be sure the flow rates are
compatible.
DANGER -- RISK OF INJURY: Never operate the spa if the suction fitting or filter baskets are broken or
missing.
DANGER -- RISK OF INJURY: Never replace a suction fitting with one that is rated less than the flow rate
marked on the original suction fitting.
DANGER -- RISK OF ELECTRIC SHOCK: Install the spa at least 5 feet (1.5 meters) from all metal surfaces.
As an alternative. a spa may be installed within 5 feet of metal surfaces if each metal surface is permanently
bonded by a minimum #8 AWG solid copper conductor to the outside of the spa’s control box.
DANGER - RISK OF ELECTRIC SHOCK: Do not permit any electrical appliances, such as lights, telephones,
radios, televisions, and etc., within 5 feet (1.5 meters) of the spa. Never attempt to operate any electrical device
from inside the spa.
WARNING -- RISK OF INJURY
•Before entering a spa, measure the water temperature with an accurate thermometer, since the tolerance of
water temperature-regulating devices varies.
•The spa water 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 young
children and when spa use exceeds 10 minutes.
•Since excessive water temperatures have a high potential for causing fetal damage during pregnancy during
early months of pregnancy, women who are pregnant, or who think they are pregnant, should always check
with their physician prior to spa usage.
•The use of alcohol, drugs or medication before or during spa use may lead to unconsciousness, with the
possibility of drowning.

Page 2 2005 Spa Owner's Manual
8/1/2005
•Persons suffering from obesity, a medical history of heart disease, low or high blood pressure, circulatory
system problems or diabetes should consult a physician before using the spa.
•Persons using medications should consult a physician before using the spa since some medications may
induce drowsiness while others may affect heart rate, blood pressure and circulation.
Hyperthermia Danger
Prolonged exposure to hot air or water can induce hyperthermia. Hyperthermia occurs when the internal
temperature of the body reaches a level 3˚F to 6˚F above the normal body temperature of 98.6˚F (or 2˚C to 4˚C
above 37˚C). While hyperthermia has many health benefits, it is important not to allow your body’s core
temperature to rise above 103˚F (39.5˚C). Symptoms of excessive hyperthermia include dizziness, lethargy,
drowsiness and fainting. The effects of excessive hyperthermia may include:
•Failure to perceive heat
•Failure to recognize the need to exit spa or hot tub
•Unawareness of impending hazard
•Fetal damage to pregnant women
•Physical inability to exit the spa
•Unconsciousness
WARNING! The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia.
Basic Spa Information
The following operating and maintenance instructions are very important and must be followed carefully. With
the proper care and maintenance, your Cal Spa will provide you with years of satisfaction and performance.
Do not be afraid to push buttons or turn knobs to learn about your new Cal Spa, as it is built with quality
materials and excellent craftsmanship.
Your new Cal Spa has been engineered with a high-powered water pump that pushes water through various
therapy jets, which will relax even the tightest muscles. In addition to the water pressure, you can add air into
the spa water with air venturi handles located seat-side that increase the intensity of your massage.
The filtering of this spa is very important. This alone will cut down on cleaning time and use of excess
chemicals. We have pre-programmed two filter cycles of two hours for every twelve hours. This can be
increased to six hours every twelve hours through the topside control panel.
Important! Keep the spa covered when not in use!
•Covered spas will use less electricity in maintaining your set temperature.
•Covering your spa will protect your spa’s finish from the sun’s ultraviolet rays.
•You are required to keep the spa covered to maintain warranty coverage.
•Covering your spa helps prevent children from drowning in the spa.
Your new Cal Spa comes equipped with an electric heater. Following the directions listed below will ensure the
most efficient operation:
•Set the spa’s operating temperature within 5˚F of the desired usage temperature and raise the temperature
one or two hours prior to usage.

Read This First!
2005 Spa Owner's Manual Page 3
8/1/2005
NOTE: This method is only for spa usage under two hours a week.
•If the spa usage exceeds two hours a week, the set temperature should remain at the desired usage
temperature.
•The air venturi handles should be used sparingly. When open, water temperature drops quite rapidly and can
also dissipate chemicals.
Allowing the water temperature to lower more than 10˚F below the desired usage temperature and reheating it
prior to usage will cause the heater to operate longer than it normally would maintaining the desired
temperature. Doing this will increase your operating cost and makes your heater work more than necessary.
The filter needs to be cleaned on a regular basis. This is very simple and only takes a few minutes. The result is
increased water clarity and equipment longevity.
Water level is very important to the operation of your spa. If the water level is too low or too high, your spa will
not operate properly. The water level should be to the middle of the skimmer area when the spa is not being
used.
We recommend that your spa water be changed every 4 to 6 months. You may find the need to change your spa
water more frequently with heavy use. When empty, your spa should be cleaned with a non-abrasive cleaner,
such as Cal Spas™ All Surface Cleaner, and then rinsed thoroughly.
See the section “Cleaning and Maintaining Your Spa” for instructions on draining your spa.
When filling your spa, always fill through the skimmer filter canister. Use only regular tap water.
WARNING: DO NOT USE SOFT WATER.

Preparing for Your New Portable Spa
Page 6 2005 Spa Owner's Manual
8/1/2005
Preparing for Your New Portable Spa
Congratulations! You have purchased a Cal Spa. With a little preparation and care, your spa will give you many
years of enjoyment. This section has been designed to provide you with all the information you’ll need to
ensure a safe, speedy and trouble-free spa delivery and set-up.
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.
Planning the Best Location For Your Spa
Here are some of the things that you will need to consider when determining where to place your new spa.
Safety First
•Do not place your spa within 10’ (3m) 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. Consider these things when you plan your location.
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 enter your spa.

Preparing for Your New Portable Spa
2005 Spa Owner's Manual Page 7
8/1/2005
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 moved, or lifted off the ground.
Preparing a Good Foundation for Your Portable Spa
Your spa needs a solid and level foundation. The area that it sits on must be able to support the weight of the
spa 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 or finish.
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. We strongly recommended
that you have a qualified, licensed contractor prepare the foundation for your spa.
Place the spa on an elevated foundation (preferably a 3” concrete slab). If you are installing the spa indoors, pay
close attention to the flooring beneath it. Choose flooring that won’t be spoiled or stained.
If you are installing your spa on an elevated wood deck or other structure, consult a structural engineer or a
contractor to ensure the structure will support the weight of 150 pounds per square foot.
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 compliment your spa and increase your enjoyment.

Electrical Set-up Before Delivery of Your Spa
When installed in the United States, the electrical wiring of this spa must meet the requirements of National
Electric Code, ANSI/NFPA 70-1999 and any applicable state or local codes. The electrical circuit must be
installed by an electrical contractor and approved by a local building / electrical inspector.
All 240V spas must be permanently connected (hard wired) to the power supply. 120V spas may use a G.F.C.I.
cord, plugged into a dedicated grounded outlet. Supplying power to a spa which is not in accordance with these
instructions will void both the independent testing agency listing and the manufacturer’s warranty.
The power supplied to the spa must be on a dedicated circuit with no other appliances or lights sharing the
power.
To determine the current, voltage, and wire size required for the spa configuration to be connected, refer to the
following:
•Wire size must comply with NEC and / or local codes.
•Wire size is determined by length of run from breaker box to spa and maximum current draw.
•We recommend copper wire with THHN insulation.
•All wiring must be copper to ensure adequate connections. Do not use aluminum wire.
•When using wire larger than #6 (10mm2), add a junction box near the spa and reduce to short lengths of #4
(10mm2) wire between the junction box and the spa.
The electrical supply for the spa must include a suitably rated switch or circuit breaker to open all ungrounded
supply conductors to comply with NEC Section 422-20. The disconnection point must be readily accessible to
the spa’s occupant. Check with local municipalities for additional code requirements.
The electrical circuit for the spa must include a suitable GFCI as required by NEC Section 680-42.

Preparing for Your New Portable Spa
110 Volt Electrical Installation Guidelines
Always follow applicable local, state and federal codes and guidelines.
•Use only a dedicated electrical line with a 20-amp breaker.
•Do not use an extension cord.
•Always use a weatherproof-covered receptacle.
•Never have your spa within 10’ of the receptacle.
•Do not bury the power cord.
•If your cord becomes damaged, replace it before next usage.
All 110V spas must have a GFCI (Figure 1). This can be either a 15-amp GFCI receptacle or a GFCI cord and
plug kit (CKIT110 - P/N ELE09700086).
Figure 1. 110V / 15 Amp GFCI Plug
Test the GFCI plug prior to every use. To test the GFCI plug version, please follow these easy instructions. (Spa
should already be plugged in and operational.)
1. Press the TEST button on the GFCI. The GFCI will trip and the spa will stop operating.
2. Press the TEST button on the GFCI. The GFCI will reset and the spa will turn back on.
The spa is now safe to use.
If the GFCI turns off (“trips”) while the spa is in use, press the RESET button. If the GFCI does not reset,
unplug the spa and call your local Cal Spas dealer for service. DO NOT USE THE SPA!
2005 Spa Owner's Manual Page 9
8/1/2005

Preparing for Your New Portable Spa
220 Volt Electrical Installation
All 220V spas are required to have a dedicated 50-Amp GFCI breaker and should only be wired by a licensed
electrician. To ensure proper wiring of your GFCI, follow these diagrams (Figure 2 and Figure 3).
•Always follow applicable local, state, and federal codes and guidelines.
•Your new 220V Cal Spa requires a dedicated, 50-Amp GFCI Service with four #6 AWG copper wires. This
will include a black and a red wire for your incoming power, a white wire used for your neutral, and a green
wire for your ground.
You can use #6 AWG wire for a distance of up to 100’. Wire run over 100’ must increase to #4 gauge. This is
the only acceptable electrical wiring procedure. Spas wired in any other way will void your warranty and
may result in serious injury.
Do not install a GFCI breaker in the main electrical panel. The further away a GFCI is installed from the spa,
the higher the risk of false tripping or resetting of the GFCI breaker. We only recommend the use of the Square
D GFCI breaker.
Before each use of your spa, you should check the GFCI. During this test, the spa should be operational.
3. Press the test button on the GFCI. The GFCI will trip and the spa will shut off.
4. Wait 30 seconds and reset the GFCI breaker by turning the breaker off then back on. Your spa will be
operational in about five seconds.
Your spa is now safe to use.

Filling and Powering Up Your Portable Spa
Never fill your spa with soft water. Soft water makes it impossible to maintain the proper water chemistry and
may cause the water to foam, which will ultimately harm the finish of the spa and void your warranty.
1. Once the spa has been placed on an approved surface and has been correctly wired by a licensed electrician,
inspect all plumbing connections in the equipment area of your spa. Ensure that these connections are secure
and that they didn’t loosen during shipment.
2. If equipped, open all gate valves, or slice valves, in the equipment area. Before operating the spa, these
valves must be in the up or “open” position.
3. Remove the filter basket and cartridge from skimmer / filter canister.
4. Place a garden hose in the skimmer / filter canister and continue filling your spa with regular tap water up to
the water level (halfway up the skimmer area).
5. (For owners of the automatic bromine generator) Make sure the dial on the face of the bromine generator
unit is turned to the OFF position.
6. Open the air relief valve (located next to the two filters, if equipped) after the air bubbles stop coming out of
it. Close the valve hand-tight.
7. If the air lock persists, open the pump unions on the suction side of the pump.
8. Once the water is at the correct level, turn on the power at the GFCI breaker. (Ensure that the 110V spas are
connected to the proper electrical outlet.)
After you turn on the power, the spa will perform a diagnostic check for 30 seconds. When the
diagnostic is complete, the spa will automatically operate at filter speed and continue heating until the
spa water temperature reaches the default temperature of 100˚F.
9. Re-install the filter and the filter basket into the skimmer / filter canister.
The spa is now ready for use.
Notes: Never run the spa with the gate valves closed or without water circulating for long periods of time.
Be careful not to over-tighten the plumbing fittings.
