5.1 Maintenance
The following inspection and cleaning procedures should be performed monthly:
Tools Needed for Maintenance:
wrenches: 10mm, 13mm, 17mm, 27mm
1)
INSPECT PROPELLER
: Check that propeller is secure on prop shaft or motor shaft
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 blades and frame so that blades
open and close 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 1 month after
initial operation and yearly thereafter. 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!
5)
GREASE BEARINGS:
Grease bearings every 4-6 months.
Use no more than 2 shots when greasing fan.
