5. 3-Phase (3ø) Wiring Connections/Hookup (For Non-Reversing 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.
IMPORTANT: 3-phase (3ø), including reversing models, are polarity sensitive. Fan rotation must be
checked to insure safe and proper performance. When viewed from the front of the
dryer, the fan must turn in the clockwise (CW) direction. If fan is running in backward
(counterclockwise [CCW]) direction, reverse any two (2) of the 3-phase (3ø)
electrical service connections to the dryer.
IMPORTANT: A CIRCUIT SERVICING EACH DRYER MUST BE PROVIDED.
a. Gas Models and Steam Models ONLY
1) 3-Phase (3ø) Wiring Connection/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.
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.
If 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.
