NOTE:

To check for proper sail switch operation (for gas models only), open the main door and while
holding main door switch plunger in, start dryer. Dryer should start but heat circuit

should not

be

activated (on). If heat (burner) does activate, shut dryer off and make necessary

adjustments.

6. The dryer

should be

operated through one (1) complete cycle to ensure that no further adjustments are

necessary and that

ALL

components are functioning properly.

BASKET (TUMBLER) 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.

7. Make a complete operational check of

ALL

operating controls.

Microprocessor controller (computer) programs/selections:

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.

8. Check the electric service phase sequence. While the dryer is operating, check to see if the blower wheel

(impellor/fan) is rotating in the proper direction. Looking from the front, the blower wheel (impellor/fan)
should spin in the clockwise (CW) direction. If it is, the phasing is correct. If the phasing is incorrect,
reverse two (2) of the three (3) leads at connections L1, L2, or L3 of the power supply to the dryer.

IMPORTANT:

If the blower wheel (impellor/fan) is rotating in the wrong direction, it will drastically
reduce drying efficiency, and it can also cause premature component failure.

9. Reversing basket (tumbler) dryers

should never be

operated with less than a 50 lb (22.68 kg) load (dry

weight), since the load’s weight effects the basket (tumbler) coast time during a direction reversal command.
It is important that the basket (tumbler) comes to a complete stop prior to starting in opposite direction.

Microprocessor Models

a. Spin and dwell (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.

b. Spin and dwell (stop) times are adjustable in the Manual (timed) Mode.

10. Check to insure that

ALL

setscrews (i.e., basket [tumbler] drive, idler, etc.) are tight.
