American Dryer Corp ML-79 manual Preoperational Instructions, Shut Down Instructions

NOTE: To check for proper sail switch operation for gas and electric 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. If heat, burner or oven, does activate; shut dryer off and make necessary adjustments.

5.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.

IMPORTANT: The dryer basket (tumbler) is treated with a protective coating. ADC suggests tumbling old clothes or material in the basket (tumbler), using a mild detergent to remove the protective coating.

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

a.For microprocessor model check controller (computer) program and 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.

7.Check the electric service phase sequence (3-phase [3Ø] models only). While the dryer is operating, check to see if the blower wheel (impellor and fan) should spin in the clockwise 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, L3 of the power supply to the dryer.

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

8.Check to ensure that ALL set screws (i.e. tumbler drive, idler, etc.) are tight.
