The following inspection and cleaning procedures should be performed monthly:
1)
INSPECT PROPELLER
: Check that propeller is secure on drive hub and that
there are no signs of damage. The blades are of a self-cleaning design and should
not require maintenance.
2)
CLEAN
regularly for best results:
• FAN MOTOR:
Remove any dust accumulation from motor using a brush or
cloth.
(DO NOT use a pressure washer).
A clean motor will run cooler and last
longer. At the same time, verify that the motor is secure in its mount.
• DAMPER:
Carefully clean dust from damper door and frame so that damper
door opens and closes freely. A brush or cloth should be used.
• GUARD:
Clean any dust or feathers from fan guards using a brush. Dirty
guards can reduce airflow.
3)
CHECK FASTENERS:
For safety, all fasteners should be inspected. Tighten any
loose connections.
4)
INSPECT FAN CONTROL:
With power disconnected, inspect all electrical connec-
tions. Wiring should be secure and in good condition. Remove any dust build-up
from control case and sensor using a soft brush or cloth.
NEVER CLEAN
ELECTRICAL EQUIPMENT WITH A PRESSURE WASHER!
