Receiving

Upon receiving the product, check to ensure all 
items are accounted for by referencing the delivery 
receipt or packing list. Inspect each crate or carton 
for shipping damage before accepting delivery. Alert 
the carrier of any damage detected. The customer will 
make notation of damage (or shortage of items) on 
the delivery receipt and all copies of the bill of lading 
which is countersigned by the delivering carrier. If 
damaged, immediately contact your representative. Any 
physical damage to the unit after acceptance is not the 
responsibility of the manufacturer.

Unpacking

Verify that all required parts and the correct quantity 
of each item have been received. If any items are 
missing, report shortages to your local representative to 
arrange for obtaining missing parts. Sometimes it is not 
possible that all items for the unit be shipped together 
due to availability of transportation and truck space. 
Confirmation of shipment(s) must be limited to only 
items on the bill of lading.

IMPORTANT

Do not lift by the fan hood. Avoid lifting fans in a way 
that will bend or distort fan parts. Never pass slings or 
timbers through the venturi of fan. Fans with special 
coatings or paints must be protected in handling to 
prevent damage.
