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.
Preparing for Your New Portable Spa
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.
Preparing a Good Foundation
Place the spa on a level foundation (preferably a 4”
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 150 pounds per square foot.
Planning the Best Location
Safety First
Do not place your spa within 10 feet (3 m) 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 will 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
muchprivacy.Thinkof yourspa’s surroundingsduring
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 bathers can clean their feet
before entering your spa.
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.

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 ELE09700086).
Test the GFCI plug prior to rst use and periodically
when the spa is powered. To test the GFCI plug
version, follow these instructions. (Spa should already
be plugged in and operational.)
Press the TEST button on the GFCI. The GFCI will1. trip and the spa will stop operating.
Press the RESET button on the GFCI. The GFCI2. will reset 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 Coleman®dealer for service.
DO NOT USE THE SPA!
All 240V spas must be permanently connected
(hardwired) to the power supply. See the wiring
diagram on page 6.
Theseinstructionsdescribetheonlyacceptable
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
National Electric Code, ANSI/NFPA 70-2008 and any
applicable local, state, and federal codes.
240 Volt Electrical Installation
Use copper wire with THHN insulation. Do not use
aluminum wire.
Use the table on the next page to determine your
GFCI and wiring requirements.
Wire runs over 85 feet must increase wire gauge
to the next lower number. For example: A normal
50 amp GFCI with four #8 AWG Copper wires run
over 85 feet would require you to go to four #6 AWG
copper wires.
Testing the GFCI Breaker
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):
Press the TEST button on the GFCI. The GFCI will1. trip and the spa will shut off.
Reset the GFCI breaker by switching the breaker2. to the full OFF position, wait a moment, then
turn the breaker back on. The spa should have
power again.
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.
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.

Filling and Powering Up Your Portable Spa
Once the spa has been placed on an approved1. 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.
Open all gate valves in the equipment area. Before2. operating the spa, these valves must be in the up
or “open” position. Once the water is at the correct level and air6. is bled, turn on the power at the GFCI breaker.
(Ensure that the 120V spas are connected to the
proper electrical outlet.)
Note: Depending on the model, when the power
is turned on to the spa, the controls 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 100˚F.
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.
Install the pre-soaked lters into the lter 9. canister.
The spa is now ready for use.
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.
VERY IMPORTANT!
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.
Remove the cartridge from lter canister.3.
Place a garden hose in the lter canister and ll 4. your spa with regular tap water about six
inches from the top.
VERY IMPORTANT!
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.
Presoak the lters in spa water.5.
VERY IMPORTANT!
You must presoak the lters before
inserting them in the lter canister.
Dry lters can allow air into the
ltration system which can cause
pump failure.

Priming the Pump
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.
Using a Phillips screwdriver, remove the front1. panel from the spa and locate the pump.
While the spa is operating, turn the bleeder valve2. counter clockwise with a small pair of pliers or
a at head screwdriver until the air has been
released from the pump.
If this is unsuccessful, loosen the white union nut3. 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.
Turn the spa on and wait for PR (Priming Mode) to1. appear on the topside display.
Press the2. Jets or Jets 1 button to turn on the
pump and let it run for 10 seconds. The pump
should be running in low speed.
Press the3. Jets or Jets 1 buttons again and let the
pump run in high speed for 10 seconds.
Press the4. Jets or Jets 1 button again to turn
off the pump. The pump should be left in the off
position for 10 to 15 seconds.
Repeat steps 1 through 4 until water is owing 5. through all the jets and all air is removed from the
plumbing.

Low and High Power Operation
Two and three pump systems can be congured to
operate on low or high power. The factory default
is low power. This section describes how the
spa operates when it is congured for low power
operation.
See page 4 for GFCI and wiring requirements for
both low and high power operation.
Spas congured for low power operation require
approximately 20% less power to operate. With low
power conguration, the spa will never use more
than 30 amps while in operation and will alternate
between 110V and 220V, while spas congured for
high power will operate continuously at 220V.
When only one pump is running, the heater will
operate at 220V. When two or three pumps are
running, the heater will automatically switch to op-
erate at 110V.
The heater light will tell you when it is operating
and what voltage it is using. See the “Heater Light”
section above.
For spas congured for high power operation, the
heater will turn on when (1) the water temperature
drops or (2) the jets are in use.

The electronic control panel displays the actual water temperature in degrees
Fahrenheit. The displayed temperature will only be current after the pump has been
running for at least two minutes.
To display the temperature that the spa is set to:
Press the• Temp UP or Temp DOWN button. The temperature setting will ash.
While the display is ashing, each time you press the • Temp UP or Temp DOWN button, the set
temperature will change up or down one degree.

The spa can be set to operate in three different
heating modes:
Standard:• When the spa is powered up, it will
automatically start in Standard heating mode.
In Standard mode, the heating system will
automatically maintain the set spa temperature.
STD will light briey on the main display.
Economy:• In Economy mode, the heating
system will only activate during ltration times.
and will heat the water to the set temperature.
Ecn will display solid if temperature is not
current and will alternate with spa temperature
if measured temperature is current.
Sleep:• In Sleep mode, the heating system will
only activate the heater during the ltering cycles
but will only heat the water to within 20°F (10°C)
of the set temperature. Like Economy mode, SLP
will display solid when temperature is not current
and will alternate with actual temperature when
it is current.
NOTE: Displayed temperature will only be current
after the pump has been running for at least two
minutes.

Freeze Protection
If the temperature sensors detect a drop to 44°F
within the heater, the pump automatically activates
to provide freeze protection. The equipment stays
on until four minutes after the sensors detect that
the spa temperature has risen to 45°F or higher.
In colder climates, an optional additional freeze
sensor may be added to protect against freeze
conditions that may not be sensed by the standard
sensors. Auxiliary freeze sensor protection acts
similarly except with the temperature thresholds
determined by the switch and without a four-
minute delay in turnoff.
Setting Filtration Cycles
Your spa is programmed to lter twice a day. The
rst cycle will begin 6 minutes after the spa is turned
on and the second cycle 12 hours later. The factory
has programmed the cycle to last for 2 hours but
this can be switched to your preference.
To set time the ltration cycle begins, turn off the
power to the spa at the time of day you would
like one of the ltration cycles to begin then turn
back on after 30 seconds. When power has been
restored, press the Temp UP or the Temp DOWN
button, followed by the Jets button. Press Temp
UP or Temp DOWN again to change the ltering
cycle duration.
The ltration cycles and their displays are as
shown:
One pump systems
F1 One hour
F2 Two hours
F3 Three hours
F4 Four hours
F5 Five hours
F6 Six hours
Two or three pump systems
Fil 2 Two hours
Fil 4 Four hours
Fil 6 Six hours
Fil 8 8 hours

Electrical Power Efciency
Your new 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 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.
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.
Light
Press the Light button to turn on the
light. Press it once again to turn the light
off. All optional lighting such as the control
panel light and cabinet perimeter lighting
is controlled by the Light button and will
turn on and off with the spa light.
