4. Electrical Connections for Gas Dryers
A wiring diagram is located inside the front wiring box.
a. Single-Phase (1ø) Dryers
The electrical connections for dryers manufactured for operation at single-phase (1ø) (2-wire) are made
through the top of the dryer, at the rear. The dryer is shipped with the three (3) connection leads (L1, L2
or N, and ground) for each basket (tumbler) compartment extending out of the top connector holes.
Each basket (tumbler) compartment has its own set of connecting leads and are electrically separate.
If local codes permit, power to the dryer can be made by the use of a flexible U.L. listed power cord/
pigtail (wire size must conform to the rating of the dryer) or the dryer can be hard wired directly to the
service breaker panel. In both cases, a strain relief must be installed where the wiring enters the dryer.
NOTE: It is recommended that a circuit servicing each dryer be provided.
b. 3-Phase (3ø) Gas Dryers
For dryers manufactured for operation at 3-phase (3ø), the electrical connections are made at the top
rear.
Providing local codes permit, power to the dryer can be made by the use of a flexible U.L. listed cord/
pigtail (wire size must conform to the rating of the dryer), or the dryer can be hard wired directly to the
service breaker. The power supply wiring should enter the dryer through the back of the outer top. A
strain relief should be used where the wiring enters the dryer.
NOTE: It is recommended that a circuit servicing each basket (tumbler) compartment be
provided.
CAUTION:The dryer must be grounded. Ground lugs have been provided in the rear wiring
boxes for this purpose.
The only electrical connections to each basket (tumbler) section are 3-phase (3ø) leads (L1, L2, and L3)
and ground. Single-phase (1ø) power (208/230V) for the control circuit is done by the factory at the
contactor (relay), and no other wiring connections are necessary.
