Steam Models
Check to ensure that (standard) steam damper or (optional) steam solenoid valve is functioning properly.
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 the dryer. The dryer should start but the heat circuit should not be
activated (on). If the heat (burner) does activate, shut the dryer off and make the necessary
adjustments.
7. Reversing tumbler dryers should never be operated with less than a 125 lb (56.69 kg) load (dry weight),
since the load's weight effects the tumbler coast time during a direction reversal command. It is important
that the tumbler comes to a complete stop prior to starting in opposite direction.
a. Microprocessor Controller (Computer) Dryer Models
1) Spin and dwell (stop) times are not adjustable in the Automatic Mode and have been preprogrammed
into the microprocessor controller (computer) for 150-seconds spin time in the forward direction
and 120-seconds in the reverse direction with a 5-second dwell (stop) time.
2) Spin and dwell (stop) times are adjustable in the Manual (timed) Mode.
b. Dual Timer Dryer Models
Both spin time and dwell (stop) time are adjustable (refer to page 40).
The 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 tumbler to remove this coating.
8. Each dryer should be operated through one (1) complete cycle to ensure that no further adjustments are
necessary and that ALL components are functioning properly.
9. Make a complete operational check of ALL operating controls.
a. Microprocessor Controller (Computer) Programs/Selections
Each microprocessor controller (computer) has been preprogrammed by the factory with the most
commonly used parameter (program) selections. If computer changes are required, refer to the computer
programming manual, which was shipped with the dryer.
b. Dual Timer Check
1) Heating Timer
2) Cool Down Timer
3) Temperature Selection Switch
