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).

This manual is the property of the owner and is required for future maintenance. Please leave it with the owner when 
the job is complete.

Safety Warning

Improper installation, adjustment, alteration, service 
or maintenance can cause property damage, injury 
or death. Read the installation, operating, and 
maintenance instructions thoroughly before installing 
or servicing this equipment.

Note: A minimum velocity of 300 fpm (1.5 m/s) is required.
