Adjustments
Airflow Switch
The airflow switch is set at the factory for proper operation. No
adjustment necessary.
The airflow switch operation may be affected by shipping
tape still in place, lack of make-up air, or an obstruction in
the exhaust duct. These should be checked and the required
corrective action taken.
WARNING
The tumble dryer must not be operated if the airflow
switch does not operate properly. Faulty airflow
switch operation may cause an explosive gas
mixture to collect in the tumble dryer.
IMPORTANT: Airflow switch vane must remain closed
during operation. If it opens and closes during the
drying cycle, this indicates insufficient airflow through
the tumble dryer. 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 airflow switch is indicating
insufficient airflow.
NOTE: To properly mount the airflow switch
bracket, or in case of a load not drying, the airflow
switch bracket may need to be checked for proper
alignment. Be sure the locator pins are securely in
their respective holes before tightening the bracket
mounting screws. This will assure proper alignment
of the airflow switch arm in the channel of the airflow
switch bracket and prevent binding of the arm.
Loading Door Switch
The door switch should be adjusted so the cylinder stops
when door is opened 2 inches (51 mm) plus or minus
0.25 inch (6 mm) . This switch is a normally open switch
and is closed by the hinge cam when the door is closed. If
adjustment is required, refer to Figure 54 and proceed as
follows:
1.
Close door and start tumble dryer, slowly open loading
door. Cylinder and heat system should shut off when door is
open 2 inches (51 mm) plus or minus 0.25 inch (6 mm) .
2.
Slowly close the loading door. When door is 2 inches
(51 mm) from being fully closed, the door switch actuating
bracket (located on the door) should depress the button and
the switch arm with an audible "click."
3.
If the actuating bracket does not operate the switch at the
appropriate door closure, bend the actuating switch arm in
or out to achieve proper actuation.

Door Strike
The door strike must be adjusted to have sufficient tension to
hold loading door closed against force of the load tumbling
against it. There is proper adjustment of pull force when
8 to 15 pounds (35.6 N – 66.7 N) is required to open door.
If adjustment is required, refer to Figure 55 and proceed as
follows:
1.
To adjust, open door, loosen acorn nut, and turn door strike
screw in or out as required.
2.
Retighten acorn nut.
