Inspection
After unpacking your exhaust
fan, carefully inspect for any
damage that may have
occurred during transit.
Inspect for loose, missing or
damaged parts. If there is
physical damage 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.
