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: A CIRCUIT SERVICING EACH DRYER MUST BE PROVIDED.
a. Gas Models
1) 3-Phase (3ø) Wiring Connections/Hookup
For gas 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.
If local codes permit, power to a gas 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.
