Electric shock hazard. Disconnect all power supplies at the main disconnect
switch before proceeding. All electrical wiring must be installed by a qualified
licensed electrician in accordance with National and local Codes.
The steambath generator is factory wired and pre-tested before shipment. Electrical power supply details are provided on
the data plate secured to the generator and as part of this manual. Refer to applicable wiring and schematic information.
1.
Check power and control circuit voltage requirements on the data plate.
NOTE:
Separate 120 VAC line is not required if optional 120 VAC control transformer has been purchased and provided
as factory equipment.
2.
Use minimum 90° C insulated copper conductors only for field wiring, sized in accordance with National and local electric
Codes. Refer to Amperage Chart below.
3.
Connect suitably sized copper equipment grounding conductor in accordance with National and local electric Codes to
ground terminal provided.
4.
Install a separate dedicated circuit breaker or other approved overcurrent protection device between the incoming
electrical supply and the generator, in accordance with National and local electric Codes.
5. IMPORTANT:
With main disconnect switch off and no electric power entering the generator, tighten all electrical
connections including all factory connections at the terminal block, fuse block, top and bottom of contactor and element
pins prior to energizing generator.

IMPORTANT:
Use minimum 90˚ C insulated copper conductors only for field wiring sized in accordance with
National and local electric Codes.
NOTE:
Consult factory for other voltage/phase combinations. CU generators are suitable for 50/60 hz. Standard control
circuit voltage for above V/PH combinations for United States, Canada and Mexico is 120 VAC. Exception: 220-240 VAC control
circuit voltage is provided on non-domestic product where power voltage is 220-240 V/3 PH, 380V/3PH, 415V / 3 PH, etc.
