Important Safety Instructions
READ AND FOLLOW ALL INSTRUCTIONS.
WARNING:
To reduce the risk of injury, do not permit children to
use this product unless they are closely supervised
at all times.
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.
Never operate the spa if the suction tting or lter
baskets are broken or missing. 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 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 external electrical appliances,
such as lights, telephones, radios, televisions, and
etc., within ve feet (1.5 meters) of the spa. Never
attempt to operate any electrical device from inside
the spa.
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 benets, 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 in 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.
WARNING -- To reduce the risk of injury:
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.
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.

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 spa.
Before Delivery
Plan your delivery route
Choose a suitable location for the spa
Lay a 5 - 8 cm concrete slab
Install dedicated electrical supply
After Delivery
Place spa on slab
Connect electrical components
Preparing for Your New Portable Spa
Pre-Delivery Checklist
Planning the Best Location
Safety First
Consider How You Will Use Your Spa
Plan for Your Environment
Consider Your Privacy
Provide a View with Your Spa
Keep Your Spa Clean
Allow for Service Access
Do not place your spa within 10 feet (3 m) of
overhead power lines.
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 will probably want to create a specic
mood around it.
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.
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.
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.
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 bathers can clean their feet
before entering your spa.
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.

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.
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 3 to 4” / 30 cm concrete
slab. Pavers, gravel, brick, sand, timbers or dirt
foundations are not adequate to support the spa.
We strongly recommend that a qualied, licensed
contractor prepare the foundation for your spa.
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, 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 (732 kg / m2).
To properly identify the weight of your new spa when
full, remember water weighs 8.33 lbs. per gallon, or
1 kg per liter. For example, an average 8’ spa holds
approximately 500 gallons, or 1892 liters, of water.
Using this formula, you will nd that the weight of the
water alone is 4,165 lbs, or 1892 kg. Combined with
the dry weight of the spa you will note that this spa
will weigh approximately 5,000 lbs, or 2267 kg, when
full of water.

240 Volt Electrical Installation
120 Volt Electrical Installation
Testing the GFCI Breaker
All 240V spas must be permanently connected (hard
wired) to the power supply. See the wiring diagram
on page 6.
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.
When installed in the United States, the electrical
wiring of this spa must meet the requirements of NEC
70 and any applicable local, state, and federal codes.
The electrical circuit must be installed by an
electrical contractor and approved by a local
building or electrical inspector.
Failure to comply with state and local codes
may result in re or personal injury and will be
the sole responsibility of the spa owner.
The power supplied to the spa must be on a dedicated
GFCI protected circuit as required by NEC 70 with no
other appliances or lights sharing the power.
Use copper wire with THHN insulation. Do not use
aluminum wire.
Use the table below and on the next page to determine
your GFCI and wiring requirements.
Wires that run over 100 feet must increase wire gauge
to the next lower number. For example: A normal 50
amp GFCI with four #6 AWG copper wires that run
over 100 feet would require you to go to four #4 AWG
copper wires.
One Pump Control System uses a VS300 control box
and requires one 40 amp GFCI and four #8 AWG
copper wires. Two Pump Control System uses a 5100
GFCI and Wiring Requirements
Always follow applicable local, state and federal codes
and guidelines.
Use only a dedicated electrical line with a 15 amp
breaker.
Cord-and-plug connections may not use a cord longer
than 15 feet (4.6 m) and must be plugged into a
dedicated 15 amp GFCI connection (NEC 680.42(A)
(2)). Do not use extension cords!
Always use a weatherproof-covered receptacle.
Receptacle shall be located not less than 5 feet (1.5
m) from and not exceeding 10 feet (3.0 m) from the
inside wall of the spa. (NEC 680.43(A))
Do not bury the power cord. If your cord becomes
damaged, replace it before next usage.
All 120V spas must have a GFCI. This can be either a
15 amp GFCI receptacle or a 15 amp GFCI cord and
plug kit as shown (CKIT110 - P/N ELE09700087).
Testing the GFCI
Test the GFCI plug prior to rst use and periodically
when the spa is powered.
1. Plug in the GFCI into the power outlet. The
indicator should turn on.
2. Press the TEST button. The GFCI will trip, the
indicator will turn off, and the spa will stop operating.
3. Press the RESET button. The GFCI will reset, the
indicator will turn on again, and the spa will turn
back on.
The spa is now safe to use.
If the GFCI 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!
Test the GFCI breaker prior to rst use and periodically
when the spa is powered. To test the GFCI breaker
follow these instructions (spa should be operating):
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.

1. Inspect the spa equipment.
3. Fill the spa.
2. Remove the cartridge from lter canister.
Place a garden hose in the lter canister and ll your spa
with regular tap water about six inches from the top.
If the water level is too low or too high, your spa will not
operate properly.
Always ll the spa through the lter canister! Failure
to do so may cause air to be trapped in the ltration
system and prevent the pumps from operating
properly.
Unscrew the cartridge and remove it.
After you remove the lter, remove the plastic
wrapper and soak it in water for 30 minutes before
you replace it. A dry lter can allow air into the
ltration system which can cause the pump to fail to
prime.
After 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 did
not loosen during shipment.
If your spa has gate valves, make sure they are all in the
UP or OPEN position.
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.
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.

5. Prime the pump.
4. Turn on power to the spa.
Your spa will perform a self-diagnostic check and go into
Priming Mode. The control panel will display either RUN
PUMPS PURG AIR --- or Priming Mode, depending on
which control panel you have.
Do the following:
1. Press the JETS or JETS 1 button once to start the pump
in low speed.
2. Press it again to switch the pump to high speed.
3. If you have other pumps, press JETS 2 or JETS 3 to
turn them on also.
Running the pumps helps the pumps prime.
When the spa is lled to the correct level, turn on the
power at the GFCI breaker. (Ensure that the 120V spas are
connected to the proper electrical outlet.)
After two minutes, the pump should prime. If it does not, follow the priming instructions on the next page. If it
does, continue with the next step.
Starting Up: Priming Mode for Neo-Pack Systems
The system will enter the priming mode. Priming Mode will display
on the control panel. In Priming Mode, all devices such as jets and
lights are operable. Jets can be turned on and off to help prime the
pump. The system will exit Priming Mode and go to the Main display
when the RETURN button is pressed, or after four minutes of activity.
Exiting Priming Mode for Neo-Pack Systems
You can manually exit Priming Mode by pressing the RETURN button.
Note that if you do not manually exit the priming mode, the priming
mode will be automatically terminated after 4 to 5 minutes. Be sure
that the pumps have been primed by this time.

6. Install the lter into the lter canister.
Make sure the lter has soaked at least 30 minutes
before you install it.
7. Adjust water chemistry.
Test and adjust the water chemistry. See the section on page 23 for instructions on water clarity.
8. Let the spa heat up.
When the spa has nished priming, the heater will activate. Put the cover on and let the spa heat to the
set temperature.

New spa owners often have difculty the rst time they start their spa and the pump fails to prime. This can be
frustrating, but these simple instructions can help you.
Sometimes air can become trapped in the pump while lling the spa. You will know this has happened when
after you have lled and started the spa, the pump does not seem to function. You will hear the pump operating,
but no water will be moving.
There are two methods of priming the pump.
The pump will not work
properly while air is trapped in it.
Continuing to operate the pump
in this way will cause damage.
Whenever you ll your spa, ll it through
the lter canister and make sure all jets
are open.
Note: If you press the Temp button
any time during Priming Mode, it will exit
that mode and begin Standard Mode.
The second method will remove a large air lock
within the pump.
1. Using a Phillips screwdriver, remove the front
panel from the spa and locate the pump.
2. While the spa is operating, turn the bleeder valve
counter clockwise with a small pair of pliers or
a at head screwdriver until the air has been
released from the pump.
3. If this is unsuccessful, loosen the white union nut
on side of the pump with channel locks. When air
is bled out, tighten the nut and set the pump on
high speed.
The rst method will remove small air bubbles
trapped in the pump.
1. Turn the spa on and wait for PR (Priming Mode) to
appear on the topside display.
2. Press the JETS 1 button to turn on the pump and
let it run for 10 seconds. The pump should be
running in low speed.
3. Press the JETS 1 buttons again and let the pump
run in high speed for 10 seconds.
4. Press the JETS 1 button again to turn off the
pump. The pump should be left in the off position
for 10 to 15 seconds.
5. Repeat steps 1 through 4 until water is owing
through all the jets and all air is removed from the
plumbing.

When rst powered up, your hot tub will perform
a self-diagnostic check and go into priming mode.
When the control panel displays PR, IMMEDIATELY
do the following:
1. Press the JETS 1 button to turn on the pump
and let it run for 10 seconds. The pump should
be running in low speed.
2. Press the JETS 1 button again and let the pump
run in high speed for 10 seconds.
3. Press the JETS 1 button again to turn off the
pump. The pump should be left in the off
position for 10 to 15 seconds.
4. Repeat steps 1 through 3 until water is owing
through all the jets and all air is removed from
the plumbing.
When the hot tub has nished priming, the heater
will be activated and the water temperature will
be maintained in standard mode. The hot tub will
heat to 100°F (37.5°C) at start up until the set
temperature is changed as described below.

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 5˚F 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
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.
