b. Steam Models
1) Check to ensure that the 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 26 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 112 lb (51 kg) load (dry weight), since the
load’s weight affects tumbler coast time during a direction reversal command. It is important that the tumbler come
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.
TUMBLER COATING
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
1) 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.
