Greenheck TBI-FS/TBI-CA/TDI (460983) - Manual (Page 7)

Removal of dust, dirt and debris - Dirt clogs cooling
openings on the motor housing, contaminates bearing
lubricant, and collects on the propeller causing severe
imbalance if left unchecked.
Periodically, thoroughly clean the exterior surface only
of the motor. If optional motor cover is installed, remove
it and clean the motor of dust, dirt and debris to aid
in motor cooling. Use caution and do not allow water
or solvents to enter the motor or bearings. Under no
circumstances should motors or bearings be sprayed
with steam or water.
Accumulations of dirt and debris on the propeller
blades may cause an unbalanced condition resulting
in excessive vibration and premature failure of the
propeller and bearings.
Dampers for Roof Upblast Configuration - If
exhausting dirty or contaminated air, the propeller
and butterfly damper assembly should be cleaned
periodically. Excessive buildup of dirt on the damper
blades may cause binding and sticking blade hinges
resulting in loss of fan performance. Clean as needed.
These fans have heavy-duty fusible link damper lifters
under very high spring tension that must be pinned so
they cannot be accidentally tripped when servicing the
fan. The fusible link damper lifters are located under
the butterfly damper blades. Point “A” shows where
the safety pin
MUST be placed when the fan is being
serviced. Point “B” shows where the safety pin is placed
for storage when the fan is in service.
Fan sizes 24, 30 and 36 also have fusible link damper
lifters, but they do not have the ability to be pinned
when servicing due to differences in lifter designs.
In either case, extreme care must be taken when
working around the damper lifter assemblies or serious
bodily injury or death may result.
