AIR FLOW LIGHT
Only on 120 and 170 Pound Manual Timer Models
The light on the front control panel indicates when the air
flow through the tumbler is less than normal. When this
light flickers on and off or stays on all the time, the
tumbler cannot operate properly. If cleaning the lint
screen does not correct the problem, other possibilities
include: Lint build-up in the exhaust line or discharge
vent, incorrect rotation of blower, lack of make-up air,
jammed back-draft damper, overloaded tumbler or
anything else that will reduce the air flow.
For 120 lb. Tumblers only.

The air flow light is wired to the normally close contact
of the air flow switch, so when the air flow switch flutters
or does not pull in, the light will advise the operator that
there is a problem, which should be corrected
immediately. It is normal for the light to come on for 2
seconds when the tumbler is started. It should go out
when the blower is up to speed.
For 170 lb. Tumblers only.
