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 6 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 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 spa occupants, but installed at least five feet from the 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 spa must be 240 volt 3 wire plus ground (6 AWG copper).

Route the cable into the equipment area for final hook-up to terminals inside the con-

trol 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 con-

nected to a non-dedicated circuit, overloading will result in “nuisance tripping” which

requires resetting of the breaker switch at the house electrical panel.
