These instructions apply to the external field installation of Multi Products actuators on Greenheck models VCD Control
Dampers.
Multi Products actuators are impedance protected, and stall type. They rotate to their stall position when power is applied and
spring return to their fail position when power is interrupted.

Instructions:
These installation instructions assume the damper is already
mounted in a duct or sleeve with the damper shaft extending
beyond the sleeve or duct 6".
1. Install the anchor bracket.
Dampers with a jackshaft
1a. Mount the anchor bracket, #1, onto the jackshaft bracket
with four
1
/4"-20 X 1/2" thread cutting screws. Orient the
anchor bracket perpendicular to the damper on the duct or
sleeve so that the bracket's shaft hole is centered on the
jackshaft.
Dampers without a jackshaft (shaft extension)
1b. Mount the anchor bracket, #1, spanning across the damper
frame flanges. Orient the anchor bracket perpendicular to
the damper on the duct or sleeve so that the bracket's shaft
hole is centered on the shaft extension. Fasten to the
damper frame with four #14 Tek screws or equal, supplied
by others. Be sure not to run the screws into the damper
linkage, which is between the flanges.
2. Note the damper shaft rotation for fail direction and orient
the actuator appropriately. The actuator assembly, #5, can
be mounted with linkage towards or away from the damper
to provide correct rotation. Make sure the linkage is as
shown in the appropriate illustration.
Note: Inspect the damper blades and the damper shaft to
determine the proper damper shaft rotation for the desired
blade fail position.
3. Insert the damper shaft through the crankarm and the nylon
bearings in the actuator assembly.
4. Hole A in the mounting bracket mates with the
1
/4" pin
of the anchor bracket, #9, which is installed by the
factory. Secure the bracket with an E-ring, #8.
Note: For clockwise fail rotation with a control shaft
extension use part #12 and #13 in place of part #8 and
#9 to fasten the actuator assembly to the anchor
bracket.
5. Position the damper blades in the fail position,
either open or closed.
6. Tighten the
5
/16" bolt, #3, in the crank arm, #4.
7. On dampers with jackshafts, if the linkage is facing the
damper, install the shaft collar, #7, with the set screw,
#6, onto the damper shaft to hold the actuator on the
shaft, otherwise the shaft collar is not needed.
8. The above wiring illustration identifies actuator
electrical connections. Wiring should be per an
approved project or job wiring diagram and must
comply with all applicable electrical codes.
9. Apply power to the actuator.
The damper blades should fully open or close and
return to the fail position when power is disconnected,
if they do not, adjustments can be made by:
-Resetting the crankarm position on the damper shaft.
-or-
-Loosening the set screw in the
5
/16" shaft collar on
the motor shaft to increase or decrease return spring
tension.
