TSI Actuator/Damper Installation
WARNING
Building prints normally determine damper location and mounting configuration. They supersede the
guidelines below.
The actuators are shipped mounted to the damper. No adjustments are needed prior to mounting
the assembly.
The damper must be installed with the damper shaft parallel to the ground (Figure 30).
Slip-fit dampers mount INSIDE the duct work. Flanged dampers bolt to the duct work. No ductwork can
be inside of dampers, or interfere with damper rotation.
Screw slip-fit damper to duct work using 1-inch or shorter screws. Make sure screws do not interfere
with damper blade rotation. Bolt flanged dampers securely to ductwork, but do not “force” damper to
fit (deforms damper).
Figure 30. Proper Damper Mounting
NOTE: If you need assistance installing the system, call TSI Customer Service at (800) 874-2811.
