Receiving and Handling

Upon receiving dampers, check for both obvious and

information on the bill of lading and file a claim with 
the final carrier. Check to be sure that all parts of the 
shipment, including accessories, are accounted for.

Dampers must be kept dry and clean. Indoor storage 
and protection from dirt, dust and the weather is highly 
recommended. Do not store at temperatures in excess of 
100°F (38°C).

codes that may apply, and wiring diagrams developed 
in compliance with the job or project design and 
specifications.
