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.
