3) 3-Phase Wiring Connections/Hookup "Reversing Models Only"
The electrical connections on ALL 3-phase (3 Ø) gas 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 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.
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 input connection
is required on a three phase (3Ø) dryer.
For gas and steam dryers manufactured for operation at
three 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.
