IMPORTANT: Dryer blower motor impellor/fan as viewed from the front must turn in the clockwise

(CW) direction, otherwise dryer efficiency will drastically be reduced and premature
component failure can result.

5. Heat Circuit Operational Test

a. Check to insure that steam damper is functioning properly.

1) The steam damper should not “slam” (open or closed) when it reaches the end of (piston) travel.

Additionally, the steam damper should not bind and/or stop during travel. If either of these conditions
occur, the flow control must be adjusted.

6. Make a complete operational check of ALL safety-related circuits.

7. A reversing basket (tumbler) dryer should never be operated with less than a 60 lbs (27.21 kg) load (dry

weight). The size of the load will affect the coast-down and dwell (stop) times. The basket (tumbler) must
come to a complete stop before starting in opposite direction.

a. Microprocessor controller (computer) dryer models

1) Spin and stop times are not adjustable in the automatic mode and have been preprogrammed into the

microprocessor controller (computer) for 120-seconds spin time and a 5-second dwell (stop) time.

2) Spin and stop times are adjustable in the manual (timed) mode.

BASKET COATING

The basket (tumbler) is treated with a protective coating. We suggest dampening old garments or cloth
material with a solution of water and nonflammable mild detergent and tumbling them in the basket (tumbler) to
remove this coating.

8. Each dryer should be operated through one complete cycle to assure that no further adjustments are

necessary and that ALL components are functioning properly.

9. Make a complete operational check of ALL operating controls.

a. Microprocessor controller (computer) programs/selections...

1) Each microprocessor controller (computer) has been preprogrammed by the factory with the most

commonly used parameter (program) selections. If computer program changes are required, refer
to the computer programming manual which was shipped with the dryer.
