To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the tumbler before servicing.
• Close gas shut-off valve to gas tumbler before servicing.

95. AIRFLOW SWITCH
Refer to Figure 50.
IMPORTANT: Airflow switch disc must remain
closed during operation. If it opens during the
drying cycle, insufficient airflow through tumbler is
indicated. If switch remains open, or pops open and
closed during the cycle, the heating system will shut
off. Cylinder and fan will continue to operate even
though the airflow switch is malfunctioning.
NOTE: Airflow switch adjustment should be made
with all tumblers operating.
Airflow switch is set at the factory for proper
operation. However, at installation, and following
repairs, airflow must be checked. Airflow switch
operation is controlled by the counterweight
position on the shaft. Moving the counterweight
changes airflow switch sensitivity. The
counterweight should be adjusted so the disc will
move away from the cabinet when lint panel is
opened 1-1/2 inches (38 mm). Adjust airflow
switch as follows:
a. Load tumbler with a cotton load.
NOTE: Airflow adjustment is much faster with one
person opening lint panel in front and another
adjusting the counterweight in the rear of tumbler.
b. Start tumbler. Open lint panel 1-1/2 inches (38
mm). Airflow disc should move away from the
cabinet, opening the switch contacts and
shutting off the heat system. This indicates
proper operation and proper adjustment.
c. If switch is not opening as described in step “b,”
it should be adjusted so it is MORE sensitive.
Depress spring clip and move counterweight a
small amount toward disc. Retest by opening
lint panel and continue moving counterweight
toward disc until switch operates as described
in step “b.”
d. If switch opens BEFORE lint panel is opened
the proper distance as indicated in step “b,” it
should be adjusted so it is LESS sensitive.
Depress spring clip and move counterweight a
small amount away from the disc. Retest by
opening lint panel and continue moving
counterweight away from disc until switch
operates as described in step “b.” Refer to
Figure 49.
Control panel, access panel, and lint panel
must be in place before attempting to adjust
airflow switch.

WARNING
Airflow switch operation may be affected by
a clogged lint screen, lack of make-up air, or
by obstructions in the vertical recirculation
stack, or in the customer installed main or
collector ducts. These conditions MUST be
checked and necessary corrections made
before adjusting airflow switch. Always
check airflow at installation. Under no
circumstances is the airflow switch to be
blocked closed or bypassed.
