NOTE: To check for proper sail switch operation, open the main door and while holding main door switch plunger in, start the dryer. Dryer should start but heat circuit should not be activated (on). If the heat system is activated, the sail switch is improperly adjusted and must be adjusted by bending the actuator arm of the sail switch toward the burner box. If the actuator arm is bent to far toward the burner box of the dryer, the dryer may not have heat when needed. After any adjustment to the sail switch, the above procedure must be repeated to verify proper operation of the sail switch.

4.The dryer should be operated through one (1) complete cycle to assure 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.

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

a. For microprocessor controller (computer) models check 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.

6.Check the electric service phase sequence (3-phase [3ø] models only). 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, and L3 of the power supply to the dryer.

IMPORTANT: If the blower wheel (impellor/fan) is rotating in the wrong direction, this will not only drastically reduce drying efficiency, but it can also cause premature component failure.

7.Reversing basket (tumbler) dryers should never be operated with less than a 50 lb (22.7 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.

a.Microprocessor Models

1)Spin times 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.

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

b.Dual Timer Models

1)Both dwell (stop) time and basket (tumbler) spin time are adjustable (refer to the illustration on page 37).

8.Check to insure that ALL setscrews (i.e., basket [tumbler] drive, idler, etc.) are tight.
