4.2 Maintenance
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.
• SHUTTER: Carefully clean dust from shutter and frame so that shutter
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
connections. 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!
