Adjustments
Air Flow Switch
The air flow switch on the 32DG model is set at the
factory for proper operation.
IMPORTANT: Air flow switch vane must remain
closed during operation. If it opens and closes
during the drying cycle, this indicates insufficient
air flow through the tumbler. If switch remains
open, or pops open and closed during the cycle, the
heating system will shut off. The cylinder and fan
will continue to operate even though the air flow
switch is malfunctioning.
Refer to the Parts and Service manual for information
on adjusting the air flow switch.
NOTE: Air flow switch operation may be affected
by a clogged lint screen, lack of make-up air, or
obstructions in the customer installed main or
collector ducts. These conditions must be checked
and corrected before attempting to adjust the air
flow switch.
Cylinder Door Switch and Strike
The door switch should be adjusted so the cylinder
stops when door is opened two inches (5.08 cm), plus
or minus 1/4 inch (6.35 mm). This switch is a
normally open switch and is closed when the door is
closed.
1. Close door and start tumbler, slowly open loading
door. Cylinder and heat system should shut off
when door is open two inches plus or minus 1/4
inch.
2. Slowly close loading door. When door is two
inches (5.08 cm) from being fully closed, the tab
on the door should contact the switch plunger and
depress it enough to close the switch with an
audible “click.” Refer to Figure 13.
3. If tab does not depress the switch plunger enough
to operate the switch, bend tab on loading door
INWARD towards machine (away from hinge)
and repeat steps 1 and 2.
4. If the tab on the door operates the switch before
the two inch distance, bend tab on loading door
OUTWARD away from machine (towards the
hinge) and repeat steps 1 and 2.
Cylinder Door Strike
Refer to Figure 14.
The door strike must be adjusted to have sufficient
tension to hold loading door closed against force of
load tumbling against it. Proper adjustment is when
eight to 15 pounds (35.6N to 80N) pull is required to
open door.
To adjust, open door, loosen jamnut and turn door
strike screw in or out as required. Retighten jamnut.
Drive V-Belt
The drive V-belt tension is automatically set by a
spring loaded idler system. There is no adjustment.
1. Remove belt guard front panel from rear of
tumbler.
2. The belt should show no signs of excess wear or
cracking. If it does, replace with a genuine
service replacement.
3. Ensure that spring loaded idler arm is free to
move by squeezing the belt together. Idler arm
should move freely with moderate
(approximately 20 pounds, 9.08 kg) of spring
force.
4. Replace the belt guard. Failure to do so will result
in the tumbler not starting.
To avoid serious injury, disconnect power
to the tumbler before performing this
operation.
