American Dryer Corp Super AD-30 manual Phase 3ø Hookup for GAS and Steam Dryers only

5.3-Phase (3ø) Wiring Connections

The only electrical input connections to the dryer are the 3-phase (3ø) power leads (L1, L2, L3, and some times 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.

a.3-Phase (3ø) Hookup - for GAS and STEAM DRYERS ONLY

For gas 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.

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. In ALL cases, a strain relief should be used both where the wiring enters the dryer and the service box.

b.3-Phase (3ø) Hookup - for ELECTRIC DRYERS ONLY

The electrical input connection is made into the electric oven contactor located at the upper rear of the dryer. Input connection wiring must be sized properly to handle the dryer's current draw. This in- formation is printed on the dryer's data label.
