Inspection
After unpacking your exhaust
fan, carefully inspect for any
damage that may have oc-
curred during transit. Inspect
for loose, missing or damaged
parts. If there is physical dam-
age to any parts of the fan, a
freight claim must be filed with
the carrier. Check to assure
that all bolts, screws and set
screws are securely tightened
and have not become loose
during transit. Retighten as
required. Rotate propeller by
hand to assure it turns freely.
