ELECTRICAL

All electrical wiring to be installed by

a qualified licensed electrician in accordance with

National Electrical Code and local electrical code.

POWER WIRING

See “Field Power Wiring” Diagrams (below)

1. Check power voltage. Use 240V rated unit when supply

is greater than 208V. (Most homes have 240V, 1PH

service). Use 208V rated unit for 208V power.

2. Use minimum 90˚ C/300V rated insulated copper

conductors only, sized in accordance with National

Electrical Code and local electrical code for the current

in Ampere Chart. If allowed by codes, NM cable may

require a larger wire size than as listed on the chart.

3. Connect suitably sized equipment grounding wire to

ground terminal provided.

4. Install a separate circuit breaker between supply and

unit. Provide a power supply disconnect within sight

of the steam generator or one that is capable of being

locked in the open position.

For single phase units, use two-wire supply source and

equipment grounding wire. Neutral (white) wire is not

required.
