Avoid isks To Children:
DANGE : ISK OF CHILD D OWNING: Extreme care must be
exercised, to prevent unauthorized access by
children. To avoid accidents, ensure that children
cannot use the spa unless they are supervised at all
times. Always cover the spa and use safety locks.
WA NING: ISK OF CHILD INJU Y: Do not permit children to use
the spa unless they are closely supervised at all
times. Lower water temperatures are
recommended for children. Children are especially
sensitive to hot water.
Avoid isks of Electrocution
DANGE : ISK OF ELECT ICAL SHOCK: Install spa at least 5 feet
(1.5m) from all metal surfaces. A spa may be installed
within 5 feet (1.5m) of metal surfaces when each
metal surface is permanently connected by a
minimum No. 6 AWG (10 mm
2
) solid copper
conductor to the wire ground connector provided on
the terminal for this purpose. Do not permit any
electrical appliance, such as a light, telephone,
radio, or television within 5 feet (1.5m) of the spa,
unless factory installed.
Connect all metal equipment, metal enclosures of
electrical equipment, metal water pipes, or conduits
to the provided ground connector with a minimum
No. 6 AWG (10 mm
2
) solid copper conductor.
Position your spa to provide proper drainage of the compartment
for electrical components. or floor-recessed spas, allow access for
servicing from above or below floor. Consideration should be
taken for water to splash out. Water can ruin wood floors and
some finishes.

4
• DO NOT use a wall switch, ground fault circuit interrupter,
circuit breaker, fuse, or plugging and unplugging the spa as a
means of turning your spa on or off for normal everyday use.
• DO NOT bring any electrical appliances into or near the spa,
with the exception of a space heater used for
winterizing/troubleshooting ONLY. Call [phone] for
instructions on this procedure.
• DO NOT operate any electrical appliances from inside the spa
or when you are wet unless such appliances are built-in by the
manufacturer.
Avoid isks of Hyperthermia
WA NING: To reduce the risk of injury, the water temperature in
a spa should never exceed 40ºC (104º ). Water
temperatures between 38ºC (100º ) and 40ºC
(104º ) are considered safe for a healthy adult.
Lower water temperatures are recommended for
young children, senior citizens, and when spa use
exceeds 10 minutes.
WATER TEMPERATURE IN EXCESS O 38ºC MAY BE
INJURIOUS TO YOUR HEALTH.
AVE TISSEMENT: DES TEMPERATURES DE L'EAU SUPERIEURES A
38ºC PEUVANT PRESENTER UN DANGER POUR LA
SANTE. L'AVERTISSEMENT: LA TEMPERATURE D'EAU
DEPASSANT 38ºC MAI EST NUISIBLE A VOTRE SANTE.
Since excessive water temperatures have a high potential for
causing fetal damage during early pregnancy, pregnant or
potentially pregnant women should limit water temperatures to
38ºC (100º ). Before entering a spa, measure the water
temperature with an accurate thermometer. The tolerances of
water temperature-regulating devices vary.

5
Hyperthermia occurs when the internal temperature of the body
reaches a level several degrees above the normal body
temperature of 98.6º (37ºC). The symptoms of hyperthermia
include drowsiness, lethargy, and an increase in the internal
temperature of the body. The effects of hyperthermia include:
• Unawareness of
impending hazard
• ailure to perceive
heat
• ailure to recognize
the need to exit spa
• Physical inability to
exit spa
• etal damage in
pregnant women
• Unconsciousness and
danger of drowning.
Avoid isks of Burns
• Before entering a spa, measure the water temperature
with an accurate thermometer since the tolerance of
temperature-regulating devices may vary by as much as
±5° (2°C).
• Test the water with your hand before entering the spa to
be sure it’s comfortable.
Warning Sign
Warning Sign Must Be Posted – The
red WARNING sign like the one
shown is packed with your new spa.
This sign must be posted in a
prominent place in close proximity to
the spa installation site immediately
upon completion of spa installation.
It is extremely important that this sign be permanently placed in
clear view of any persons using the spa. Occasional spa users may
not be aware of some of the dangers hot water poses to pregnant
women, small children, and people under the influence of alcohol.
If you did not receive a warning sign or your sign has become
damaged, please contact our 24/7 technical support line at
[phone] for a replacement.

Basic Safety Guidelines
Your Cool Nights spa is meant to be enjoyable, healthful and
relaxing. Below are some basic safety guidelines to follow every
time you use your spa.
1) Always check the temperature of your spa before entering.
High water temperatures can be hazardous to your health.
2) Persons suffering from heart disease, diabetes, high or low
blood pressure and pregnant women should consult a doctor
before using your spa.
3) Persons under the influence of medication, drugs, or alcohol
should not be allowed into your spa.
4) Do not allow children to use your spa without continuous
supervision of an adult.
5) Do not use your spa alone.
6) The G CI breaker must be tested prior to using your spa each
time to ensure it operates properly.
7) Any electrical devices near your spa must be G CI protected
and out of reach from inside the spa.
8) Keep all breakables away from the spa area.
9) Lock the cover on your spa when not in use.
10) Enter and exit the spa slowly. Wet surfaces can be slippery.
11) Prolonged immersion can be hazardous to your health.
12) Maintain water chemistry in accordance with manufacturer’s
instructions.

I n s t a l l a t i o n
Proper planning is an important consideration when installing your
new spa. Site selection is a critical step and should be given some
serious thought. Planning ahead, before the delivery of your spa,
makes the installation process easier. The following information is
provided to assist you in site preparations.
1) Always comply with local building codes with respect to gates,
fences, etc.
2) Be sure your spa has proper access to water, drainage and
electricity.
3) Properly support its weight. There are many ways to support
your spa. In most cases, a 4-inch thick cement pad suffices. [Or
you may purchase a durable, synthetic spa pad by calling the
24/7 technical support line at [phone].] Please consult
your spa sales representative before constructing a base.
4) Be sure your spa will fit into the space you have chosen.
5) Ensure there is proper access into the area of the spa for
normal servicing.
6) Provide adequate ventilation for the humidity created by your
spa. In most cases, a Spa Hard Cover is sufficient.
7) Check the load carrying capabilities of the floor on which the
spa will reside. Most homes meet the requirement of 80 pounds
per square foot.
8) Protect the pump and all equipment from the weather by
ensuring the cabinet panels are secure at all times.
Important – When building a skirt or sinking a spa into a deck or
ground, allow a minimum of 36 inches (1 meter) of unobstructed
access to all sides of your spa. This ensures proper serviceability to
internal plumbing and equipment. Consider your design carefully.
The more access the better. Make the access door in a logical
place (i.e. near controls and equipment). Call the 24/7 technical
support line at [phone] for more details.

8
E l e c t r i c a l S p e c i f i c a t i o n s
Important – Qualified and licensed electricians must perform all
electrical hookups. The following specifications must be followed in
order to ensure proper performance and safety.
WA NING: Starting an incorrectly wired spa could cause
severe damage to the mechanical equipment or
even bodily harm. Have your licensed electrician
verify G CI (or RCD) wiring with the schematics on
pages 9-10 prior to starting the spa or call the
technical support line at [phone].
Caution: ailure to abide by specifications listed may result in
damage to the equipment and will void the warranty.
US/Canada:
All spas must be wired with a G CI breaker in the service panel
(see table below for proper sizing). ailure to do so will cause
equipment damage and will not be covered under your warranty.

Parts with extra low voltage not exceeding 12v must be
inaccessible to a person in the spa. Earthed appliances must be
permanently connected to fixed wiring. Parts incorporating
electrical components, except remote control devices, must be
located or fixed so that they cannot fall into the spa. Appliances
should be supplied through a residual current device (RCD) having
a rated residual operating current not exceeding 30ma.
Means for disconnection must be used in fixed wiring in
accordance with wiring rules.
Important – To allow the 240V G CI to function properly, connect
the white Neutral wire from the spa to the Neutral terminal on the
G CI breaker, not the Neutral bus in the G CI breaker box. An
improperly connected Neutral causes the G CI breaker to trip.

S t a r t u p
Important – Read these step-by-step startup procedures before
starting your spa. ailure to follow any of these steps listed may
result in damage to the equipment and may void your warranty.
Special Note: If you are unsure of any of the above startup
procedures, please call the 24/7 technical support line at
[phone]. or best results, read each step in its entirety before
proceeding.
Caution: Running the spa pump dry (without water running
through it) can cause IMMEDIATE damage and will
void the warranty! Be sure that the spa is installed
properly in accordance with the instructions in this
manual.
Refer to the following picture for an explanation of your spa’s
controls, components, and technical terms. Note that not all
models have all features and components.

15
Before Adding Water
Before adding water, go through these simple steps now to
prevent common issues when setting up your spa for the first time.
Verify that the following have all been rechecked.
1. Turn off all power to the spa at the main breaker panel.
2. Open the side panels to access the internal components.
3. Check that all slide valves are opened (T-handles
pulled out) to the heater and all pumps.
4. Check that there are no obvious signs of loose
wires or broken pipes.
5. Check that the two heater unions are tight. These are hand-
tightened and do not need any kind of special tool to tighten
them.
Caution: Do not use a wrench. Over-tightening may cause
damage to unions and gaskets, which will not be
covered under warranty.
6. Check that the unions on the pump are tight.
7. Clean out any foreign debris from within the service access
area or inside of the spa itself.
8. With the drain open and filters removed, thoroughly rinse out
the spa with warm water until the drained water runs clear. Run
water through the filtration canister and jet lines to remove any
incidental dust, dirt, and debris that may have accumulated
during shipment or installation. Drain all water completely.
9. Make sure that the spa drain valve is closed and the cap is on
tight (see page 27).
10. Install the filter.
11. Check that all of the spa jets are open (turned full counter-
clockwise).
12. Now is the best time to clean and polish the surfaces of your
spa (see page 28-29).

16
Filling Your Spa
Now it's time to fill your spa with water. Do not turn
on the electricity yet until the spa is completely
filled. To properly fill your spa:
1. Make sure that the filters (in the filtration
canister) are gently screwed into place. Turn
them clockwise until they stop being careful
not to over-tighten them (this avoids cracking
the filter).
2. Connect a standard garden hose to a faucet with regular cold
tap water (not softened water or hot water).
Caution: The water from your hot water tank should not be used
to fill the spa.
3. Put the AquaClara pre-filter (if equipped) on the other end of
the hose, turn on the water, and allow any sediment to be
flushed out.
4. Put the AquaClara pre-filter (if equipped) into the filtration
canister and turn on the hose.
Important: To assure that the pump is properly primed, fill the
spa through the filter area only.
5. ill the spa until the water level is about 1” above all jets (or
about ½” below the pillow). Do not over fill.
Note: Every person entering a spa displaces a given volume of
water, so adjust water level to the number of people regularly
using the spa.
Turn off the hose and check again for any small leaks.
Start-up Instructions
Caution: Do not turn on any pump until your spa is properly
filled with water. Running any pump without water in
your spa can cause IMMEDIATE damage, which is not
covered under warranty!
By now you have rechecked your spa’s mechanical connections
and filled it with water to about 1” above all jets by adding cold
tap water through the pre-filter. Turn on power to the spa at the
main breaker panel and test the operation of the electrical
system. If you encounter a problem, please reference the
troubleshooting guide.

17
1. Turn on the breaker and test the operation of the Ground- ault
Circuit Interrupter (G CI) breaker by pushing the small button.
This should automatically trip the spa's circuit breaker.
DANGE : If this breaker does not trip, immediately call your
electrician. Do not use your spa!
Only if pushing this button successfully trips this circuit breaker
should you reset this breaker and proceed to the next step.
2. Go to the topside control panel. The spa first goes into a 5-
minute Priming mode, indicated by “Pr” message. Water
heating is disabled during priming. To exit Priming mode and
begin normal spa operation, press “Up” or “Down” button.
3. Press the Jets (Jets 1) button. You should hear the pump turn
on, see water circulating, and see the Jets light illuminate on
the panel.
4. Press the Jets (Jets 1) button again. You should hear the pump
turn on a higher speed.
Caution: If water is not flowing from the jets in the spa after 2
minutes, turn the power off at the main panel and
bleed air from the system (see page 22). Turn the
power on again. Sometimes momentarily turning
the pump off and on will help to prime. Do not do
this more than four times.
5. If the water is running smoothly through the lines, open the air
control valve to the jets and you should see an increase in jet
pressure. Check and adjust the water and airflow of every jet if
necessary.
Each jet in your spa can be adjusted for massage intensity and
directional flow. Turn the outer jet dial counterclockwise to
increase the water volume and clockwise to turn it off. Pivot
the angle of a jet to achieve an optimal massage.
An air mixture intensifies the level of your massage. Turn the air
control valve counterclockwise to increase the air mixture and
clockwise to turn it off.
To minimize heat loss, close the air control valve when your spa
is not in use.

18
6. Press the Jets (Jets 1) button a third time to turn off the pump.
Note: The pump remains on if filtration or heat is needed.
7. Press the Light button to turn the spa Light on. Verify the spa
Light is on.
8. Press the Light button a second time to turn the spa Light off.
9. If equipped, press the Jets 2 button. You should hear the pump
turn on, see water circulating, and see the Jets2 light illuminate
on the panel.
10. Press the Jets 2 button again to turn off the pump.
11. If equipped, press the Blower button. You should hear the
blower turn on, see water bubbling, and see the blower light
illuminate on the panel.
12. Press the Blower button again to turn off the blower.
