FIELD INSTALLATION INSTRUCTIONS
NOTE: FOR DAMPERS
INSTALLED IN DUCTS
Extended Control Shaft is
installed from outside of duct
after damper is installed.
Install as shown below.
Crossover Blade Axle
(Do not attach Control
Shaft here!)
Before Installing Damper in the Duct
1. If damper has more than one blade, determine which
blade axle will be driven by the extended control
shaft. Always attach extended control shaft to a blade
axle which is directly connected to the main linkage
tiebar. DO NOT attach extended control shaft to a
crossover blade axle.
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.
After Damper Is Installed in Duct
1. Push extended control shaft through hole in duct and
onto drive blade axle. Retainer clip should "click" into
groove on drive blade axle and hold shaft into place.
Standard Control Shaft location is the third blade
from the bottom on dampers with three or more blades.
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.
Caution
Stand off bracket with bearing is needed to support
the extended control shaft. If not installed as directed,
the extended control shaft may not operate the damper
correctly.
