a. Gas Models and Steam Models Only
1) 3-Phase (3ø) Wiring Connections/Hookup
For gas dryers 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 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.
IMPORTANT: A CIRCUIT SERVICING EACH DRYER MUST BE PROVIDED.
b. Electric Models 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 information
is printed on the dryer’s data label.
Providing local codes permit, power to a gas
dryer 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.
