American Dryer Corp. AD-385 - Manual (Page 32)

4. Make a complete operational check of ALL safety related circuits:
a. Door Switch(es)
b. Hi-Limit thermostats
c. Cycling Thermostats
d. Sail Switch
NOTE: The sail switch can be checked for proper operation by opening the lint door while the
heating circuit (gas) is active (on). The heating unit should shut off within a few
________ seconds. If not, make necessary adjustments to sail switch._____________________________
5. Make a complete operational check of ALL operating controls.
NOTE: If computer program changes are required, refer to the computer programming section
of the manual supplied with the dryer.
6. 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.
_______
7. Check the electric service phase sequence (3-phase [So] models only). While the dryer is
operating, check to see if the blower wheel (impeller/fan) is rotating in the proper direc-
ion. Looking from the front, the blower wheel (impeller/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 LI, L2, 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.
