interlock. Next, push the test button on the GFCI and close the service door.
The product 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
prevent unauthorized access by children. To avoid accidents, ensure that children
cannot use this swim spa unless they are supervised at all times.
DANGER – Risk of Injury. The suction fittings in this swim 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 that the flow rates are compatible.
Never operate swim 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.
DANGER – Risk of Electric Shock. Install at least 5 feet (1.5m) from all metal sur-
faces. As an alternative, a swim spa may be installed within 5 feet of metal surfac-
es 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 swim spa.
WARNING – To reduce the risk of injury:
a) The water in a swim spa should never exceed 40˚C (104˚F). Water tem-
peratures 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 swim spa use exceeds 10 minutes.

GLOSSARY OF SWIM SPA TERMINOLOGY
1. THERAPY JETS
Your new swim spa features a variety of jet styles. All jets, regardless of style
return the water to the swim spa. Air is mixed with the water by using the air
controls creating a gentle to most vigorous massage. Water flow is adjusted
by simply turning the outer face of the jet.
2. JET DIVERTER VALVE
Located on the topside of the swim spa, this valve physically diverts the
flow of water from one jet zone of the swim spa to another jet zone.
Be sure that no sand or particles are brought into the swim spa as they
can cause the diverter to seize up. It is best to turn the diverter valve
only when the pump is turned off.
3. AIR CONTROL VALVES
These are located around the top of your swim 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.
4. TOPSIDE CONTROL PANEL
You may safely control all functions from inside or outside your swim spa using the
Topside Control Panel. This Panel is used to control the water temperature, pumps, the swim
spa light, automatic filtration cycles and other advanced functions. The digital display will
give you a constant temperature readout and will notify you in case of certain malfunctions.
Several user programmable functions are also available.
5. SWIM JETS
The swim jets are operated by directing the water flow from the pumps to the jets located in
the swim end of the swim spa by turning the diverter valves.
6. PERSONAL REMOTE CONTROL
Your swim spa has an additional remote which allows the user to con-
trol the stand up jet therapy cove. By pressing the control one time, you
will activate the pump. Press the pad again to turn the pump off.
7. EQUIPMENT ACCESS PANEL
Located behind the side panel below the Topside Control Panel, this area houses the major
components responsible for the swim spas operation. Those components include the pumps,
heater, control panel box, Ozonator, and LED light system. Pump and equipment placement
may vary by model.

GLOSSARY OF SWIM SPA TERMINOLOGY
8. ACCESS PANELS
These are located on all four sides of the swim spa. All of the panels are removable should
service be required.
NOTE: Note: The above drawing illustrates the panel placement on the swim spa.
WARNING: Do Not Remove Access Panels Without Turning Off Power To The Swim Spa.
9. DRAINING YOUR SWIM SPA
Due to the physical size of the swim spa, we recommend draining your swim spa with a
submersable sump pump. Draining your swim spa with a conventional swim spa drain is not a
reasonable option.
10. WEIR GATE
The weir gate is the horizontal door located in front of the filters that trap debris in the filter
area.
11. SWIM SPA LIGHT
Your swim spa lights are designed for safety and are located on the interior walls of your
swim spa. The on/off switch is located on the topside control panel.
12. EQUIPMENT CONTROL SYSTEM
This houses the wiring and electrical components necessary to operate the swim spa.
13. SWIM SPA HEATER
This element is an electric heater housed in a stainless steel tube. It is thermostatically con-
trolled and equipped with a high-limit temperature safety shut-off sensor. The high-limit sen-
sor cannot be reset until the temperature within the heater assembly drops several degrees
below the shut-off temperature of 108° - 110° F. Should the high-limit switch trip repeat-
edly, contact your dealer or qualified service representative to diagnose the problem. Your
swim spa will heat approximately 1˚- 2˚ per hour, on average when the cover is closed. These
times may vary and the swim spa should have a cover installed.

GLOSSARY OF SWIM SPA TERMINOLOGY
14. SLICE VALVES
These valves are used by service personnel to shut off water to the
heater, main pump system and secondary pump system so that the
water does not need to be drained should the swim spa require
service.
*NOTE: Slice valves must be completely open during normal
operation.
15. MAIN PUMP
The main pump produces water flow through the jets and has a high and low speed. Low
speed will produce efficient water circulation during filtration and gentle jet action. High
speed should be used for maximum jet action. The water flow may be directed to different
areas of the swim spa depending on the position of the diverter controls.
16. SECONDARY PUMP
This pump produces water flow through the stand up jet system.It also supplies water flow
to the swim jets or therapy jets depending on the position of the diverter valve. The second
pump can be controlled by the topside panel and also the personal remote mounted on the
surface of the swim spa.
17. PUMP UNION
These are used by service personnel to easily service the pumps.
18. HEATER UNION
These are used by service personnel to easily service the heater.
19. OZONATOR
Your onzonator will operate in conjunction with the filter system. Ozone is a powerful gas
that oxidizes contaminates in the water.

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 swim 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 swim spa must include a 50 AMP switch or circuit breaker to open all
non-grounded supply conductors to comply with section 422-20 of the National
Electrical Code. The disconnect must be readily accessible to the swim spa occu-
pants, but installed at least five feet from the swim spa. A Ground-Fault Circuit
Interrupter (GFCI) must be used to comply with section 680-42 of the National
Electrical Code. A ground fault is a current leak from any one of the supply con-
ductors 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 swim 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 swim spa must be hooked up to a “dedicated” 240 volt, 50 amp
breaker and GFCI. The term “dedicated” means the electrical circuit for the swim
spa is not being used for any other electrical items (patio lights, appliances, garage
circuits, etc.). If the swim 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
Swim spa installation is simple when properly planned. It is important that you read the following
information carefully and consult with your Master Spas dealer.
1. Access - The actual dimensions of your new swim spa will determine the amount of space that
is needed in moving the swim 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 over-
head cables. Any other space limiting obstacles such as trees or shrubs must be evaluated.
2. Surface/Pad Requirements - When your new swim spa is filled with water and bathers, it may
weigh as much as several tons. It is imperative that the base beneath the swim spa can support
the entire weight. The swim 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 reinforcement bars crossed throughout the pad.
IMPORTANT
Be sure to locate your swim spa so that the equipment remains above grade and is not subject
to flooding.
The equipment side(s) of the swim spa must be accessible in the event that future service is need-
ed. In the event that service is required, your dealer will need at least 2 feet of clearance around
the perimeter of the swim spa. Periodical maintenance checks require entry into the equipment
bay. When possible, it is wise planning for the future to leave access, to all sides of the swim spa in
the event your swim spas plumbing requires maintenance. Your swim spa warranty does not cover
the cost of providing access for service.
GENERAL CONSIDERATIONS FOR OUTDOOR INSTALLATION
Proper planning will increase your total enjoyment factor with your new swim spa. Listed below are
some additional items to consider when planning your installation.
• How swim spa will complement landscaping and vice versa
• View from inside swim spa and view of swim spa from inside of home
• Exposure to sunlight and shading from trees
• Privacy
• Getting to swim spa from house and return
• Proximity to dressing rooms and bathrooms
• Storage for swim spa chemicals
• Local building codes (if applicable)
• Power cable
NOTE: The Swim Spa is to be used in private, residential use only. Operating an Swim Spa for
commercial use will void the warranty.

INSTALLATION INSTRUCTIONS
1. Put swim spa in final position that allows for access to equipment and swim spa components.
2. Remove front skirt panel "A" to access the electrical connections.
3. Be sure all pump and heater unions are secure. Each pump has 2 unions and the heater has
2 unions. A newly delivered swim spa may have loose unions caused in transporting the swim
spa. Check that all slice valves are open, in the up position. The slice valves may become
closed during transportation of the swim spa.
Airlock
Pump Union
Slice Valve
4. Fill the swim spa to the “minimum safe water level” sticker.
5. Turn on power to the swim spa. If your swim spa is equipped with two electrical supplies,
make sure that they are both turned on. The swim spa will go through its priming mode. This
lasts approximately 5 minutes. The purpose of the priming mode is to help insure that the jet
pumps have been primed with water and are ready to operate. It may be necessary in some
instances to bleed air from the jet pumps in your swim spa, if after the priming mode the
swim spa pumps run but do not move water the pump may have an air lock.
Due to the nature of water flow and hydro-therapy pumps, please be advised that air locking
of pumps may occur. Master Spas, Inc. has taken measures to reduce the possibility of this,
but it still may occur, especially after filling the swim spa. This is not a service covered by the
