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.
