ELECTRIC

ELECTRICAL SERVICE SPECIFICATIONS (PER DRYER)

IMPORTANT: 208 VAC AND 230/240 VAC ARE NOT THE SAME. When ordering, specify exact voltage.

NOTES: A. When fuses are used they must be dual element, time delay, current limiting, class RK1 or RK5 ONLY. Calculate/determine correct fuse value, by applying either local and/or National Electrical Codes to listed appliance amp draw data.

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 3-phase (3Ø) dryers must be 3-pole type.

IMPORTANT: The dryer must be connected to the electric supply shown on the data label. In the case of 208 VAC or 230/240 VAC, the supply voltage must match the electric service specifications of the data label exactly.

▲! WARNING

208 VAC and 230/240 VAC are not the same. Any damage done to dryer components due to improper voltage connections will automatically void the warranty.

NOTE: ADC reserves the right to make changes in specifications at any time without notice or obligation.

Electrical Connections

NOTE: A wiring diagram is included with each dryer and is located in the front control box area.

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. Providing local codes permit, power connections to the dryer can be made by the use of a flexible underwriters laboratory listed cord/ 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.

Gas Model and Steam Model Dryers

These electrical connections are made at the terminal block located in the electric service/relay box at the rear, upper left hand corner of the dryer. To gain access into this service box, the service cover (upper back guard) must be removed.

Electric Model Dryers

For electric model dryers made to operate at 208 VAC, or 230/240 VAC, the electrical input connection is made into the terminal block located at the upper rear of the dryer (refer to the illustration below). For electric model dryers made to operate at 380 VAC, 416 VAC, 440 VAC, or 480 VAC, the electrical input connection is made to the oven relay located at the upper rear of the dryer (refer to the illustration below). Input connection wiring must be sized properly to handle the dryer’s current draw. This information is printed on the dryer’s data label.

NOTE: A circuit servicing each dryer must be provided.
