The only electrical input connections to the dryer are the
3-phase (3ø) power leads (L1,L2,L3 andsometimes 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 model and steam model 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.
c. 3-Phase (3
ø) Wiring Connections (Hookup) - for REVERSING MODELS ONLY
The electrical connections on
ALL 3-phase (3ø) gas model and steam model 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.
NOTE: A 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 a flexible U.L. listed 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.
