Installation, Operation and Maintenance Instructions
Receiving and Handling
Upon receiving dampers, check for both obvious and
hidden damage. If damage is found, record all necessary
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).
