Important Safety Instructions

When installing and using this electrical equipment, always follow basic safety precautions. Following
these instructions will help make your rst spa session
a pleasurable one.
READ AND FOLLOW ALL INSTRUCTIONS
A licensed electrician may be required to upgrade your standard receptacle and/or circuit breaker.
DANGER -- RISK OF ACCIDENTAL DROWNING:
Do not allow children to be in or around a spa unless a responsible adult supervises them. Keep the spa cover on and locked when not in use. See instructions enclosed with your cover for locking procedures.
DANGER -- RISK OF INJURY: The suction ttings in this spa are sized to match the specic water ow
created by the pump. Should the need arise to replace
the suction ttings, or the pump, be sure the ow
rates are compatible. DANGER -- RISK OF INJURY: Never operate the
spa if the suction tting or lter baskets are broken
or missing. DANGER -- RISK OF INJURY: Never replace a
suction tting with one that is rated less than the ow rate marked on the original suction tting.
DANGER -- RISK OF ELECTRIC SHOCK: Install the spa at least 1.5 meters from all metal surfaces. As an alternative, a spa may be installed within 1.5 meters 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 external electrical appliances, such as lights, telephones, radios, televisions, and etc., within
1.5 meters of the spa. Never attempt to operate any electrical device from inside the spa. This does not apply to lights, stereos and televisions that are built in to the spa as factory options from Cal Spas™.
WARNING – RISK OF INJURY
The spa water should never exceed 40˚C. Water temperatures between 38˚C and 40˚C are considered
safe for a healthy adult. Lower water temperatures are recommended for young children and when spa use exceeds 10 minutes.
High water temperatures have a high potential for causing fetal damage during 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.
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 2˚C to 4˚C above the normal body temperature of 37˚C. While hyperthermia has many health benets, it is
important not to allow your body’s core temperature
to rise above 39.5˚C. Symptoms of excessive
hyperthermia include dizziness, lethargy, drowsiness and fainting. The effects of excessive hyperthermia may include:
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 high­powered 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

The ltering of this spa is very important. It will
minimize cleaning time and the amount of chemicals needed to keep your spa water balanced. The two daily
pre-programmed lter cycles of two hours in duration
can be increased to six hour cycles if the need arises. This can be accomplished through the topside control

panel. IMPORTANT: Keep the spa covered when not in
use!
Covered spas use less electricity while maintaining a set temperature.
Covering your spa will protect your spa’s nish
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 efcient operation:
NOTE: This method is only for spa usage under two hours a week.
Keep the spa’s operating temperature 3˚C below
the desired usage temperature when not in use. One or two hours before use, set the temperature to the desired temperature.
If the spa usage exceeds two hours a week, the set temperature should remain at the desired usage temperature.
The air venturis should be used sparingly. When open, water temperature drops quite rapidly and can also dissipate chemicals.
Allowing the water temperature to lower more than
6˚C 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 lter needs to be cleaned or changed on a regular
basis. This process takes only a few minutes and 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 nd 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 lling your spa, always ll through the skimmer lter canister. Use only regular tap water.
WARNING: DO NOT USE SOFT WATER.

Preparing for Your New Portable Spa

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. Your dealer can provide information on which permits may be required and how to obtain them prior to the delivery of your Cal Spa™.

Preparing for Your New Portable Spa

Planning the Best Location

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 3 meters of overhead power lines.
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 specic 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 nd 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
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.
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-
lled basin nearby for bathers to rinse their feet before
enter your spa.
Allow For Service Access
Make sure the spa is positioned so that access to the equipment compartment and all side panels will not be blocked.
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

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 nish.
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 qualied, licensed contractor prepare
the foundation for your spa. Place the spa on a level foundation (preferably a 10
cm concrete slab). If you are installing the spa indoors,
pay close attention to the ooring beneath it. Choose ooring that will not be damaged 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 68 kg 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.

230 Volt Electrical Installation

All 230V 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 8.
The electrical wiring of this spa must meet the requirements of 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.
RCD and Wiring Requirements
The power supplied to the spa must be on a dedicated RCD protected circuit with no other appliances or lights sharing the power.
Preparing for Your New Portable Spa
Use copper wire with THHN insulation. Do not use aluminum wire.
Use the table below to determine your GFCI and wiring requirements.
When wires larger than #6 AWG are required, install a junction box near the spa and use #6 AWG wire between the junction box and the spa.
Wire runs over 26 m must increase wire gauge to the next lower number. For example: A normal 50 amp RCD with four #8 AWG copper wires run over 26 m would require you to go to four #6 AWG copper wires.
Testing the RCD Breaker
Test the RCD breaker prior to rst use and periodically
when the spa is powered. To test the RCD breaker follow these instructions (spa should be operating):
Press the TEST button on the RCD. The RCD will 1. trip and the spa will shut off.
Reset the RCD breaker by switching the breaker 2. to the full OFF position, wait a moment, then turn the breaker back on. The spa should have power again.

Gas Heater Hook-up

Ultimate Fitness Series spa owners may buy and install a separate gas heater and pump for use with their spa. This option may be purchased separately from your local distributor.
Spa owners are responsible for ensuring installation of their gas heater conforms to local, state, and federal regulations. The electrical and gas installation must be performed by contractors and approved by a local building / electrical inspector. Failure to do so may void your warranty.
All Ultimate Fitness Series spas are plumbed with a gas heater ready union located inside the cabinet at either
the front or rear, depending on the model. (See the gures below and on the next page.) Properly installed,
they can be attached to an external gas heater. Customers are responsible for creating openings in the panel to accommodate the lines and wiring. The gas heater should be located not less than 3m and no more than
7.6m away from the spa. To connect the plumbing for an external gas heater:
Disconnect the ready union.1. Cut off both sides of the union and discard it.2. Create two 6.35 cm diameter holes through the spa panel.3. Use two 5 cm (2”) couplings to connect the hoses to 3m - 4.5m 5 cm (2-3/8”) diameter PVC lines.4.

Filling and Powering Up Your Portable Spa

11
Preparing for Your New Portable Spa
Never ll 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 nish of the spa and void your warranty.
Once the spa has been placed on an approved 1. 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 did not loosen during shipment.
If equipped, open all gate valves in the equipment 2. area. Before operating the spa, these valves must be in the UP or OPEN position.
Remove the lter basket and cartridge from 3. skimmer/lter canister.
Place a garden hose in the skimmer/lter canister 4. and ll your spa with regular tap water to the
proper water level (halfway up the skimmer area).
(For owners of the automatic bromine generator) 5. Make sure the dial on the face of the bromine generator unit is turned to the OFF position.
Open the air relief valve (located next to the two 6.
lters, if equipped) after the air bubbles stop
coming out of it. Close the valve hand-tight. Once the water is at the correct level and air is 7.
bled, turn on the power at the RCD breaker.
NOTE: When the power is turned on to the spa, it
will perform a diagnostic check for approximately ve
minutes. When the diagnostic is complete, the spa
will automatically operate at lter speed and continue
heating until the spa water temperature reaches the
default temperature of 37.5˚C.
If no water is owing when the pump is running 8.
there could be an air pocket at the suction side of the pump. Shut off power to the spa and loosen the pump union on the suction side of the pump to bleed the air. When air is bled, turn power back on.
Re-install the lter and the lter basket into the 9. skimmer/lter canister.
The spa is now ready for use. NOTE: 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 ttings.

8005 and 9005 Electronic Control Operation

When rst powered up, the electronic
system will perform a self-diagnostic check and then it will automatically heat to and
maintain a temperature of 37.5˚C until you
change the set temperature as listed in the “Temperature Adjustment” section below.
These instructions will describe features and options that your particular spa may not be equipped with.
Initial Start-up
When your spa is rst powered up, it displays some conguration codes and
then goes into priming mode (Pr will appear on the display panel). This mode lasts up to four minutes and then the spa begins to heat to its pre -programmed

standard, economy, and sleep modes.
Press MODE/PROG to enter mode programming.1. Press the DOWN button to cycle through to the 2.
desired mode.
Press MODE/PROG to conrm selection.3.
Standard Mode: This is programmed to maintain the desired temperature. Note that the last measured spa temperature displayed is current only when the pump has been running for at least two minutes. The “STAND” icon will display until the mode is changed.
Economy Mode: Economy mode heats the spa to the
set temperature only during lter cycles. The “ECON”
icon will display until the mode is changed. Pressing the JETS 1 button while in economy mode puts the spa in standard-in-economy mode, which operates the same as standard mode but reverts back to economy mode automatically after one hour. During this time, pressing the MODE/PROG button will revert to economy mode immediately.
Sleep Mode: Sleep mode heats the spa to within 11˚C of the set temperature only during lter cycles. The
“SLEEP” icon will display until the mode is changed. Standby Mode: Pressing “Warm” or “Cool” then
“Jets 2” will turn off all spa functions temporarily. This
is helpful when changing a lter. Pressing any button
resets the spa.
Jets 1 and Jets 2
Press the JETS 1 button once to turn pump 1 on or off and to shift between low and high speeds if equipped.
