Before Installing Damper in the Duct

axle which is directly connected to the main linkage

Control Shaft location is the first blade from the bottom  
on dampers with one or two blades.  
2. Install the stand off bracket with bearing over the  
extended control shaft and screw bracket to duct. Make  
sure screws (provided by others) do not interfere with  
damper linkage or blade movement.  
2. Cut hole approximately 1 in. (25mm) diameter in  
duct where damper drive blade axle will be located.  
Hole must provide clearance for enlarged portion of  
extended control shaft.

the extended control shaft. If not installed as directed,  
the extended control shaft may not operate the damper  
correctly.  
After Damper Is Installed in Duct
