Specifications

2. Connect the conduit-encased leads to the disconnect switch,

or circuit breaker. Connect the wire leads to the appropriate

labeled terminal on the terminal block. The ground wire must

be connected to the ground connection as shown in Figure

17 , Figure 18 or Figure 19 .

3. Check the electrical service phase sequence (three phase on-

ly). If one of the power leads is a “high leg,” connect it to lead

L3 in the tumble dryer. The cylinder must rotate clockwise

and the fan must rotate counterclockwise (as viewed from the

front of the tumble dryer – with selector switch in non-reverse

position). If not, interchange leads L1 and L2 in the tumble

dryer connection box.

Jumper Configuration Instructions

Changing the transformer configuration jumper is required, PRI-

OR TO SUPPLYING POWER TO THE MACHINE, if any of

the following apply:

IMPORTANT: Failure to install the proper configuration

jumper may result in damage to sensitive electronic

controls and may void warranty.

• You have 400 – 415 Volt service and are connecting a model

rated for 380 Volt operation.

Ferrite Ring Installation

Gas and Steam Models with RM Control Suffix Only (Models Through 7/31/11)

The ferrite ring provided in the literature packet must be installed over the power leads during connection of electrical service. The

ferrite protects the sensitive electronic controls from destructive electrical disturbances which may be present on power lines to the

machine. Failure to properly install the ferrite ring may result in damage to the electronic controls and will void control warranty.

To install:

1. Immediately after connection of power leads and before ap-

plying power to machine, locate each of the incoming service

leads including ground.

2. Snap the ferrite ring closed over all the service leads inside of

the contactor box as shown. It is important that the ferrite ring

be installed inside the contactor box. Refer to Figure 20 . Do

not install the ferrite outside of the box or other area. Make

sure that service leads are in the center of the ferrite before

closing the ring so as not to pinch or damage leads.
