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 mm2) 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.
