Wiring the Hydrotherapy Spa
This procedure must be performed by a qualified,
licensed electrician in accordance with the nation-
al electric code, and with all local, state, and feder-
al electric code. Under no circumstances should
the hydrotherapy spa be wired by someone other
than a qualified electrician.
Before you have the spa wired, make sure that the
spa is in the desired position and that it can be easily
serviced, if needed.
The spa operates on a 240 volt power source. It must
be wired directly into a grounded circuit with a 45 amp
circuit breaker and a Ground Fault Circuit Interrupter
(GFCI) capable of carrying 45 amps. No other appli-
ance should be on the same circuit.
A wire connector is provided on the electronics pack
of the spa to connect a minimum No. 6 AWG (13.3
mm
2
) solid copper conductor between the spa and
any metal equipment, electrical enclosure made of
metal, metal water pipes, or conduit within five feet of
the spa.
Three options for wiring the spa are shown at the
right. A wiring diagram is also found on the inside of
the electronics pack for reference.
