INSTALLATION PROCEDURES
3-5
Each dryer should be connected to an independently protected branch circuit. The dryer
must be connected with copper wire only. Do not use aluminum wire, which could cause a fire
hazard. The copper conductor wire / cable must be of proper ampere city and insulation in
accordance with electric codes for making all service connections.
NOTE:
The uses of aluminum wire will VOID WARRANTY.

NOTES: A. Fuse ratings are dual element – time delay – current limiting, class RK1 or
RK5 only.
B. Circuit breakers are thermal magnetic (industrial) type only. For others,
calculate / verify correct breaker size according to appliance amp draw rating
and type of breaker used.
C. Circuit breakers for 3Ø dryers must be 3 – pole type.

Electrical Connections
NOTE:
A wiring diagram is included with each dryer and is affixed to the panel inside the
right side control cabinet.
The only electrical input connections to the dryer are the 3 – phase (3Ø) power leads (L1, L2
and L3), GROUND, and in the case of 4 wire service, the neutral. These electrical connections are
made at the power distribution block located in the left side control cabinet.
Providing local codes permit, power connections to the dryer can be made by the use of a
flexible Under writers Laboratory listed chord / pigtail (wire size must conform to rating of the
dryer), or the dryer can be hard wired directly to the service breaker. In all cases, a strain relief
must be used where the wire(s) enter the dryer electrical service (relay) box.
NOTE:
A circuit serving each dryer must be provided.
