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 swim 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 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 iden-
tified 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 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 surfaces.
As an alternative, a swim 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 swim spa.
WARNING – To reduce the risk of injury:
a) The water in a swim spa should never exceed 40˚C (104˚F). Water tempera-
tures 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

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 turn-
ing 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 control 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.

DO NOT DIVE.
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 controlled
and equipped with a high-limit temperature safety shut-off sensor. The high-limit sensor 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 repeatedly, 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.

14. SLICE VALVES
These valves are used by service personnel to shut off water to the heat-
er, 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.

!! TRAINER 12, 14, 17 !!
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 connected 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 occupants, 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 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 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.

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 overhead
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 needed. 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.
