configurations pertaining 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 spa owner to ensure that electrical connections 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 (8.36mm
gauge wire) and must be connected securely to a grounded metal structure such as a cold
water pipe. The supply wiring to the spa must utilize a symmetrically grounded system. The
spa must not be wired to electrical systems utilizing no ground (IT) or TN-C grounding. Be
sure to have a licensed electrician examine and ensure proper grounding is provided. See
chart on next page for wire size conversion. All Master Spas equipment packs are wired
for 230 VAC only. The only electrical supply for your 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 spa occupants,
but installed at least five feet from the 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 spa must be hooked up to a "dedicated" breaker(s) and RCD.
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 connected
to a non-dedicated circuit, overloading will result in "nuisance tripping" which requires
resetting of the breaker switch at the house electrical panel.
