IMPORTANT SAFETY
INSTRUCTIONS (CONT.)
(For units with GFCI)
WARNING – This product is provided with a ground-fault circuit interrupter
located on the front panel of selected swim spas and on the power cord of
120 volt convertible spas. The GFCI must be tested before each use. With the
product operating, open the service door. When the product stops operating,
this merely indicates that the door is equipped with an electrical interlock.
Next, push the test button on the GFCI and close the service door. The prod-
uct should not operate. Now open the service door, push the reset button
on the GFCI and close the service door. The product should now operate
normally. When the product fails to operate in this manner, there is a ground
current flowing indicating the possibility of an electric shock. Disconnect the
power until the fault has been identified and corrected.
DANGER – Risk of Accidental Drowning. Extreme caution must be exercised to pre-
vent unauthorized access by children. To avoid accidents, ensure that children can-
not use this spa unless they are supervised at all times.
DANGER – Risk of Injury. The suction fittings in this spa are sized to match the spe-
cific water flow created by the pump. Should the need arise to replace the suction
fittings or the pump, be sure that the flow rates are compatible.
Never operate spa if the suction fittings are broken or missing. Never replace a suc-
tion fitting with one rated less than the flow rate marked on the original suction
fitting.
DANGER – Risk of Electric Shock. Install at least 5 feet (1.5m) from all metal sur-
faces. As an alternative, a spa may be installed within 5 feet of metal surfaces if
each metal surface is permanently connected by a minimum 8AWG (8.4mm2) solid
copper conductor to the wire connector on the terminal box that is provided for
this purpose.
DANGER – Risk of Electric Shock. Do not permit any electric appliance, such as a
light, telephone, radio, or television, within 5 feet (1.5 m) of a spa.
WARNING – To reduce the risk of injury:
a) The water in a spa should never exceed 40˚C (104˚F). Water temperatures
between 38˚C (100˚F) 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.

Located on the topside of the spa, this valve physically diverts the flow of water from one jet
zone of the spa to another jet zone.
Be sure that no sand or particles are brought into the spa as they will cause the diverter to
seize up. It is best to turn the diverter valve only when the pump is turned off.
Your new Master Spa features a variety of jet styles.
All jets, regardless of style return the water to the spa.
Air is mixed with the water by using the air controls (if
equipped) creating a gentle to most vigorous massage.
Water flow is adjusted by simply turning the outer face
of the jet. Your Master Spa will have a combination
of pulsating, rotating, dual pulsating and directional
adjustable jets.

NOTE: When water features are not going to be used for an extended period of time, turn valve
slightly to allow some water to flow when pump is on to prevent stagnent water from
developing in the water lines.
7. AIR CONTROL VALVES
These are located around the top of your spa. You may increase or decrease the force of your
jets by opening or closing the air control valves. Typically, one dial controls the air to water
ratio and mix to one group of jets. When not in use the air controls should be kept in the
closed position, as air bubbles tend to cool the water.
8. TOPSIDE CONTROL PANEL
You may safely control spa functions from inside or outside your spa using the Topside
Control Panel. This Panel is used to control the water temperature, pumps, the spa light,
automatic filtration cycles and other advanced functions. The digital display will give you a

ELECTRICAL INSTALLATION REQUIREMENTS
Permanently Connected Equipment Assembly with Pump(s), Heaters, Luminaine, Ozone, Spa Side
Control(s), Pump shut off device, and Audio/Video Components.
Note: Some of the above components may be optional or not available with every spa model.
ELECTRICAL INSTALLATION REQUIREMENTS
HAVE YOUR ELECTRICIAN READ THE FOLLOWING INFORMATION
BEFORE INSTALLATION BEGINS
Electrical connections made improperly, or the use of wire gauge sizes for incurring
power which are too small, may continually blow fuses in the electrical equipment
box, may damage the internal electrical controls and components, may be unsafe
and in any case will void your warranty.
It is the responsibility of the spa owner to ensure that electrical connections are
made by a qualified electrician in accordance with the National Electrical Code and
any local and state electrical codes in force at the time of installation.
These connections must be made in accordance with the wiring diagrams found
inside the control box. This equipment has been designed to operate on 60Hz.
alternating current only, 240 volts are required. Make sure that power is not
applied while performing any electrical installation. A copper bonding lug has been
provided on the electrical equipment pack to allow connection to local ground
points. The ground wire must be at least 8 AWG copper wire and must be con-
nected securely to a grounded metal structure such as a cold water pipe. All Master
Spas equipment packs are wired for 240 VAC only. The only electrical supply for
your spa must include a 50 AMP switch or circuit breaker to open all non-ground-
ed supply conductors to comply with section 422-20 of the National Electrical
Code. The disconnect must
be readily accessible to the spa occupants, but installed at least five feet from the
spa. A Ground-Fault Circuit Interrupter (GFCI) must be used to comply with sec-
tion 680-42 of the National Electrical Code. A ground fault is a current leak from
any one of the supply conductors to ground. A GFCI is designed to automatically
shut off power to a piece of equipment when a ground fault is detected.
Power hook-up to the spa must be 240 volt 3 wire plus ground (6 AWG copper)
8 AWG copper ground.
Route the cable into the equipment area for final hook-up to terminals inside
the control panel. The spa must be hooked up to a “dedicated” 240 volt, 50 amp
breaker and GFCI. The term “dedicated” means the electrical circuit for the spa
is not being used for any other electrical items (patio lights, appliances, garage
circuits, etc.). If the spa is connected to a non-dedicated circuit, overloading will
result in “nuisance tripping” which requires resetting of the breaker switch at the
house electrical panel. Rev. 11/11

SITE PREPARATION / GENERAL GUIDELINES
Portable spa installation is simple when properly planned. It is important that you read the follow-
ing information carefully and consult with your Master Spas dealer.
1) Access - The actual dimensions of your new spa will determine the amount of space that is
needed in moving the spa from curbside to its final installation area. Be sure to measure side
yard dimensions, gates or doors and vertical obstructions such as roof overhangs and overhead
cables. Any other space limiting obstacles such as trees or shrubs must be evaluated.
2) If the spa is being installed indoors, dimension limitations such as stairs, ceilings and walls must
be taken into consideration. Please have your Master Spas dealer or delivery service review site
or installation plans prior to delivery.
3) Surface/Pad Requirements - When your new spa is filled with water and bathers, it may weigh
as much as several tons. It is imperative that the base beneath the spa can support the entire
weight. The spa must be on a uniformly firm, continuous, and level surface. The recommended
foundation is a concrete pad with a minimum thickness of four (4) inches with steel reinforce-
ment bars crossed throughout the pad.
IMPORTANT
When installing your spa indoors, on a wood deck, or balcony, the same load requirements must
be met. Total load may be as much as 90 pounds per square foot. You should speak with a quali-
fied contractor or your local building department to confirm that your surface is adequate for sup-
porting a spa. Be sure to locate your spa so that equipment remains above grade and is not subject
to flooding.
The equipment side(s) of the spa must be accessible in the event that future service is needed.
Periodical maintenance checks require entry into the equipment bay. When possible, it is wise plan-
ning for the future to leave 2 feet of access to all sides of the spa in the event your spas plumbing
requires maintenance. Your spa warranty does not cover the cost of providing access for service.
GENERAL CONSIDERATIONS FOR OUTDOOR INSTALLATION
Again, proper planning will increase your total enjoyment factor with your new spa. Listed below
are some additional items to consider when planning your installation.
• How spa will complement landscaping
and vice versa
• View from inside spa and view of spa from
inside of home
• Exposure to sunlight and shading from trees
• Privacy
• Getting to spa from house and return
• Proximity to dressing rooms and bathrooms
• Storage for spa chemicals
• Local building codes (if applicable)
• Power cable
GENERAL CONSIDERATIONS FOR INDOOR INSTALLATION
Installing your spa indoors creates an entirely different set of considerations. With proper planning,
no matter what room your spa goes in, it will be your favorite room.
• Work with your Master Spas dealer and
contractor to insure all local building, electri-
cal and plumbing codes are met
• Plan for a floor drain to drain off excess water
or for draining and cleaning your spa
• A ventilation fan may be necessary due
to high humidity created by your spa
• Finished material in your spa room should
also be capable of withstanding increased
humidity
