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:
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.
