Mounting
1. Ensure the damper can
move freely through its
entire range of motion,
and fix any binding
before installing the
actuator. Turn the
damper blade to its
fully closed position.
2. Press (to the right)
and hold the gear
disengagement lever
(see the illustration),
rotate the actuator to the
fully closed position,
and release the lever.
NOTE: Depending on
the damper-seal
design, backing
the actuator
off its stop
approximately 5°
may provide tight
damper shut-off.
3. Align the actuator and
slide it onto the shaft.
4. Leaving a gap between
the actuator and
mounting surface to
prevent any binding,
finger-tighten the nuts
on the V-bolt.
5a. Insert the non-rotation
bracket (HMO-4002
supplied or HMO-4001
“T” bracket available
separately) into the
slot at the base of the
actuator and secure the
non-rotation bracket
with two #8 or #10 self-
tapping screws. (This
is the recommended
method.)
