a. Gas and Steam Model Dryers ONLY
1) 3-Phase (3ø) Wiring Connection/Hookup
For gas and steam dryers manufactured for operation at
3-phase (3ø), the electrical connections are made at the power
distribution block located in the service box at the rear, upper
left corner of the dryer. The ground connection is made to the
copper lug also provided in this box. To gain access to the
service box and contactor, the service box cover must be
removed
5. 3-Phase (3ø) Wiring Connections/Hookup
The only electrical input connections to the dryer are the 3-phase (3ø) power leads (L1, L2, L3, and some-
times 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.
IMPORTANT: A CIRCUIT SERVING EACH DRYER MUST BE PROVIDED.
b. Electric Dryers ONLY - 3-Phase (3ø) Hookup
The electrical input connection is made into the electric oven contactor located at the upper rear of the
dryer. Input connection wiring must be sized properly to handle the dryer's current draw. This in-
formation is printed on the dryer's data label.
Providing local codes permit, power to a gas or steam dryer can be made by the use of a flexible U.L.
listed power cord or pigtail (wire size must conform to rating of dryer), or the dryer can be hard wired
directly to the service breaker panel. In ALL cases, a strain relief must be installed where the wiring
enters the dryer and service box area.
