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 wire
tie still in place, lack of make-up air, or an obstruction in the ex-
haust duct. These should be checked and the required corrective
action taken.

The tumble dryer must not be operated if the airflow
switch does not operate properly. Faulty airflow

switch operation may cause an explosive gas mix-
ture to collect in the tumble dryer.

IMPORTANT: Airflow switch vane must remain closed
during operation. If it opens and closes during the dry-
ing 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 air-

flow.
NOTE: To properly mount the airflow switch bracket, or
in case of a load not drying, the airflow switch bracket
4
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.
