IMPORTANT: There is no regulator provided in an L.P. (liquid propane) dryer. The water column
pressure must be regulated at the source (L.P. tank), or an external regulator must be
added to each dryer.
4. Make a complete operational check of ALL safety related circuits:
a. Door Switch(es)
b. Hi-Limit thermostats
c. Cycling thermostat
d. Sail switch (for Gas Models and Electric Models Only)
NOTE: The sail switch can be checked for proper operation by opening the lint door while heating
circuit (gas burner/electric oven) 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 [3ø] models only). While the dryer is operating, check to
see if the blower wheel (impeller/fan) is rotating in the proper direction. Looking from the front, the blower
wheel (impellor/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/fan) is rotating in the wrong direction, this will not only
drastically reduce drying efficiency, but it can also cause premature component failure.
