Mounting
Post
NOTE:
Post mounting is typically used for
internal
duct
mounting.
1. Position the damper for its “normal” position.
2. Connect the damper’s blade clip or drive arm
with the clevis pin and cotter pin.
3. Mount the offset bracket to either the damper
frame or the duct.
4. Check that the linkage will not bind as the shaft
extends and retracts.
Right Angle
NOTE:
Right-angle mounting is typically used for
external
duct
mounting.
1. Slide the crank arm over the damper shaft.
2. Determine whether the damper shaft must rotate
clockwise (CW) or counterclockwise (CCW).
3. Locate the half-circle cutouts on the outside
corners of the bracket.
4. Place the appropriate half circle cutout over
(for clockwise rotation) or under (for counter
clockwise rotation) the damper shaft).
CAUTION
Pneumatic
devices must
be supplied
with clean,
dry control
air. Any other
medium (e.g.,
oil or moisture
contamination)
will cause the
device to fail.
