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 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.
