IMPORTANT: There is no regulator provided in an L.P. dryer. The water column pressure
must be regulated at the source (L.P. tank) or an external regulator must be
added to each dryer.
b. Electric Models
1) Check the oven contactor(s) to insure that the electric oven is cycling properly.
c. Steam Models
1) Check to insure that steam damper is functioning properly.
a) The steam damper should not "slam" (open or closed) when it reaches the end of (piston) travel.
Additionally, the steam damper should not bind and/or stop during travel. If either of these
conditions occur, the flow control must be adjusted. Refer to the bottom illustration on page 35
for air adjustment instructions.
6. Make a complete operational check of ALL safety-related circuits (i.e., lint drawer switch, and sail switch
on gas models).
NOTE: To check for proper sail switch operation, 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.
7. A reversing basket (tumbler) dryer should never be operated with less than a 60 lb. load (dry weight). The
size of the load will affect the coast-down and dwell (stop) times. The basket (tumbler) must come to a
complete stop before starting in opposite direction.
a. Microprocessor (computer) Dryer Models
1) Spin and 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 and stop times are adjustable in the Manual (timed) Mode.
b. Dual Timer Dryer Models
1) Spin and stop times are adjustable at the reversing timer (refer to page 58).
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.
