1)ELECTRICALLY HEATED MODELS ONLY

The only electrical input connections to the dryer are the 3-phase (3ø) power leads (L1,L2,L3 and sometimes neutral) and ground. Single-phase (1ø) power for the control circuit is done internally to the dryer. No single-phase (1ø) input connection is required on a 3-phase (3ø) dryer.

CAUTION: The dryer must be grounded. A ground lug has been provided for this purpose.

Input connection wiring must be sized properly to handle the dryer's current draw. This information is printed on the dryers data label.

NOTE: A CIRCUIT SERVING EACH DRYER MUST BE PROVIDED.

The electrical input connections are made at the electric oven contactor located inside the assembly at the rear center upper section of the dryer. The ground connection is made to a copper lug also provided in this area. To gain access, remove oven rear service cover.

IMPORTANT: A strain relief must be used where the input wiring enters the oven assembly.
