If a 120 V.A.C. circuit is to be used, make wiring changes as fol-

lows:

1. Disconnect white wire from heater element terminal “2” and

connect it to terminal “4.” The heater will now operate at 120

V.A.C., 750W, 6.3A.

2. For 120 V.A.C, 1500W, 12.5A operation, add the short red

jumper wire (provided) between terminals “1” and “2”.

3. Remove alarm light wire leads from terminals “1” and “3” of the

high temperature limit. Remove white wire lead from limit ter-

minal “1” and reconnect at limit terminal “3”. Secure wire leads

with wire tie so there is no interference with unit operation.

NOTE: Terminal numbers are marked on the side of the blower

housing, above the heater elements.
