ELECTRICAL REQUIREMENTS

All Models
Note: Electrical requirements by model is shown in Model Specifications. Only electrical configurations pertain-
ing to the models referenced in this manual are shown.
HAVE YOUR ELECTRICIAN READ THE FOLLOWING INFORMATION
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 connec-
tions are made by a qualified electrician in accordance with codes regulated by the
authority having jurisdiction at the time of installation.
These connections must be made in accordance with the wiring diagrams found
inside the control box and in this manual. This equipment has been designed to
operate on and requires 230V, 50Hz service. Make sure that power is not applied
while performing any electrical installation. A bonding lug for bonding copper wire
has been provided on the electrical equipment pack to allow connection to local
ground points. The ground wire must be at least 8 AWG (8.36mm2 copper wire
unless local or state codes require a heavier gauge wire) and must be connected
securely to a grounded metal structure such as a cold water pipe. See below chart
for wire size conversion. All Master Spas equipment packs are wired for 230 VAC
only. The only electrical supply for your swim spa must include a switch or circuit
breaker to open all non-grounded supply conductors to comply with BS7671 (or
other local jurisdiction code or law). The disconnect must be readily accessible to
the swim spa occupants, but installed at least five feet from the swim spa. Residual
Current Device (RCD) must be used to comply with this manual, BS 7671, or any
local electrical code or law requirements. A residual current is a current leak from
any one of the supply conductors to ground. An RCD is designed to automatically
shut off power to a piece of equipment when a ground fault is detected.
Route the cable into the equipment area for final hook-up to terminals inside the
control pack or junction box. The swim spa must be hooked up to a "dedicated"
breaker(s) and RCD. 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, over-
loading will result in "nuisance tripping" which requires resetting of the breaker
switch at the house electrical panel.
Permanently Connected Equipment Assembly with Pump(s), Heaters, Luminaine,
Ozone, Swim 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 swim spa model.
See the swim spa specification section of this owner's manual for the control system installed in
your swim spa.
