3) 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: A separate circuit serving each dryer must be provided.
If local codes permit, power to a gas or steam dryer can be made by the use of flexible power cord/
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 three 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.
