6. 3-Phase (3ø) Wiring Connections/Hookup (for Reversing Models Only)
The electrical connections on ALL 3-phase (3ø) gas dryers and steam dryers are made into the rear
service box located at the upper left area of the dryer. Electrical connections for electrically heated dryers
are made in the electric oven area located at the upper rear area of the 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 separate circuit servicing each dryer must be provided.
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.
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.
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 contactor, the service box cover must be removed.
