5. 3-Phase (3 ø) Wiring Connections
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.
a. 3-Phase (3ø) Hookup - for GAS and STEAM DRYERS ONLY
Providing local codes permit, power to the dryer can be made by the use of a flexible U.L. listed cord/
pigtail (wire size must conform to the rating of the dryer), or the dryer can be hard wired directly to
the service breaker. In ALL cases, a strain relief should be used both where the wiring enters the
dryer and the service box.
b. 3-Phase (3ø) Hookup - for ELECTRIC DRYERS ONLY
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.
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 contactor, the service box cover must be removed.
