unauthorized access by children. To avoid accidents, ensure that children cannot use this spa
unless they are closely supervised by an adult at all times.
4. 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 to replace with same model suction fittings for safety and compatible flow rates. NEVER
OPERATE THE SPA IF THE SUCTION FITTINGS ARE BROKEN OR MISSING. NEVER
REPLACE A SUCTION FITTING WITH ONE RATED LESS THAN THE FLOW RATE MARKED
ON THE ORIGINAL SUCTION FITTING.
5. DANGER – RISK OF INJURY: Do not remove suction grate. Suction through drains and skimmer
is powerful when the jets in the spa are in use. Damaged suction grate can be hazardous to
children and adults with long hair. Should any part of the body or hair be drawn into these fittings
or stuck onto the fittings, turn off the spa immediately. As a precaution, long hair should NOT be
allowed to float freely in the spa.
6. DANGER – RISK OF ELECTRIC SHOCK: Install the spa at least 5 feet (1.5 m) from all metal
surfaces. As an alternative, a spa maybe installed within 5 feet (1.5 m) of metal surfaces if, in
accordance with the National Electrical Code, each metal surface is permanently connected by a
minimum 8 AWG (8.4mm2) solid copper conductor to the wire connector on the terminal box that is
provided for this purpose.
7. DANGER – RISK OF ELECTRIC SHOCK: Do not permit any electric appliances such as light,
hair dryer, telephone, radio, or television with 5 feet (1.5 m) of the spa. Never operate any
electrical appliances from inside the spa or while wet.
8. DANGER: To reduce risk of injury:
a. The water in a spa 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.
b. Since excessive water temperatures have a high potential for causing fetal damage during the
early months of pregnancy, pregnant women should limit spa water temperatures to 100°F
(38°C).

5 rev. 2011-5-26
c. Before entering a spa, the user should check the water temperature with an accurate
thermometer since tolerance of water temperature regulating devices can vary and not reflect
the proper temperature.
d. The use of alcohol, drugs, or medication before or during spa use is prohibited and may lead to
unconsciousness with the possibility of drowning.
e. Obese persons and persons with a history of heart disease, low or high blood pressure,
circulatory system problems, or diabetes should consult a physician before using a spa.
f. Persons using medication should consult a physician before using a spa since some medication
may induce drowsiness while other medications may affect heart rate, blood pressure, and

INSTALLATION INSTRUCTIONS
Read all instructions in this manual prior to having your spa installed at the selected location, whether
indoors or outdoors. IMPROPER INSTALLATION MAY RESULT IN EQUIPMENT DAMAGE AND VOID
THE WARRANTY.
SURFACE AND PAD REQUIREMENTS
1. We recommend that your new spa be placed on a 6” (15 cm) thick reinforced concrete pad or level
foundation capable of supporting the total filled weight of your specific spa model. The foundation
should support the entire base of the spa and must offer structural integrity for the life of the spa. A
typical swim spa, filled with water, could weigh as much as 8 tons, and if the concrete is not fully
cured, it could easily crack. AN UNEVEN OR UNSTABLE FOUNDATION OR THE USE OF
SHIMS OF ANY KIND MAY CAUSE THE SPA TO BUCKLE, DISTORT, AND/OR CRACK, AND
WILL VOID THE WARRANTY ON YOUR SPA.
2. If your spa is located near water sprinklers, adjust or cap them so the water will not hit the wood
cabinet of the spa.
3. Access gates “fencing/wall” must be self-closing and self-locking. Check your local codes for
regulations regarding fences and gates.
4. Ensure that the spa installation and location allows a clear and unobstructed access to the spa. It
is the responsibility of the owner to provide clear access on all sides of the spa for service. Failure
to do so may result in additional charges or assessments to service and/or repair the spa.
5. Ensure that water drains away from the spa in order to keep water out of the equipment
compartment and away from all electrical components.
6. Assure accessibility is maintained to your spa should the need arise. Your spa is an appliance and
may require occasional service requirements. Assure the installation allows access to the
equipment area, side panels, and removal of the spa if possible. Construction or reconstruction
costs associated with spa removal or reinstallation are not covered by the warranty.
ELECTRICAL INSTALLATION REQUIREMENTS
IMPROPER INSTALLATION MAY RESULT IN EQUIPMENT DAMAGE AND VOID THE WARRANTY.
NOTE: Do not turn on electrical power to your spa until you are told to do so later in the Owner’s
Manual.
1. We strongly recommend that only a licensed and bonded electrician perform the electrical
installation. Improper electrical connections may damage the equipment, cause injury, cause a
fire, and void your spa warranty.
2. It is the responsibility of the spa owner to ensure that a qualified electrician performs the electrical
installation. This installation must be in accordance with the National Electrical Code; local and
state electrical codes; and the manufacturer’s instructions.
3. This equipment has been designed to operate on 240V 60Hz alternating current.

12 rev. 2011-5-26

•Remove the handle from the jet selector valve supplied by the pump you are priming.
•Loosen the pump union on the suction side of the pump until some water starts gushing out of
the pump union.
•Tighten the pump union.
8. After the priming mode, the control panel will display two dashes --. The system will take about 2
minutes to register the water temperature. Set the desired temperature by pressing the Warm or
Cool key.
9. Re-attach the front cabinet panel.
10. Due to the size of the swim spa, heating will occur at a rate of approximately 0.5°F (0.3°C) per
hour. For spas equipped with an additional optional heater, heating will occur at a rate of
approximately 1°F (0.6°C) per hour.
11. After completing the above steps, it is necessary to ensure proper water chemistry. See the Water
Balance section in the manual.
12. Place the thermal cover on the spa to conserve energy and to keep it ready for use.

FEATURE OPERATIONS
JET SELECTOR VALVE (DIVERTER VALVE)
Your spa may be equipped with a jet selector valve (diverter valve). This valve can be used to divert jet
power from one area in the spa to another area. This valve is fully adjustable and can be used to suit
the user’s desired effect. The valve may be slightly harder to turn when the jet pump is on high speed.
This is normal due to high rate of water flow and pressure present in the valve.
AIR CONTROL VALVES
Your spa may be equipped with air controls. The air control is an on/off valve that allows air to be
introduced into a specific jet configuration resulting in a more vigorous jet action. Turn the valve handle
clockwise to turn the air on, and counterclockwise to turn the air off. Opening the valve increases jet
pressure and closing the valve decreases the jet pressure.

WATER FEATURES AND WATER FEATURE CONTROL VAVLE
Your spa may be equipped with water features. They are turned on/off by the water feature control
valve. Turn the valve handle clockwise to turn the water features on, and counterclockwise to turn the
water features off. Water features are always supplied by the spa pump.
STEREO SYSTEM
Your spa may be equipped with a stereo system and a spa side stereo control panel. The stereo
manufacturer’s owner’s manual is provided within the spa owner’s manual. In addition to the following
instructions, please refer to the stereo manufacturer’s owner’s manual for the operation of the stereo
system.
Note: It is imperative that you keep your stereo system clean and dry. The spa is equipped with a self-
closing stereo door to protect the unit from moisture intrusion. Stereo equipped spas should be
protected from direct contact with water streams from irrigation systems. During use, the stereo door
should remain closed. Audio CD should be dry before inserting into the stereo unit.
