Installation, Operation and Maintenance Manual
Please read and save these instructions for future reference. Read carefully before attempting to assemble, install,
operate or maintain the product described. Protect yourself and others by observing all safety information. Failure
to comply with these instructions will result in voiding of the product warranty and may result in personal injury
and/or property damage.
These instructions apply to the external field installation of Honeywell actuators on Greenheck model VCD control
dampers when they are duct mounted or sleeved.
These models are direct drive actuators that rotate to their energized position when power is applied and spring
return to their fail position when power is disconnected.

Instructions for FATPA Direct Drive
Series
These installation instructions assume the damper is
already mounted in a duct or sleeve with the damper shaft
extending beyond the duct or sleeve a minimum of 6
inches (152mm).
1. INSTALL THE STANDOFF BRACKET
Dampers with a jackshaft
1a. Remove the
1
⁄2 in. (13mm) ball bearing from the
standoff bracket. Mount the stand-off bracket (Item
#7) with [4]
1
⁄4-20 x
1
⁄2 in. (M6 x 12mm) spinlock bolts
and nuts (Items #4 and 5). Orient the stand-off bracket
(Item #7) so the hole is centered on the jackshaft. See
Figure 1, With Jackshaft.
Dampers without jackshaft (Shaft Extension)
1b. Mount the stand-off bracket (Item #7) spanning
across the damper frame flanges. Fasten to the
damper frame with [4]
1
⁄4-20 x
1
⁄2 in. (M6 x 12mm)
spinlock bolts and nuts (Items #4 and 5). Be sure not
to run the screws into the damper linkage, which is
between the flanges.
2. MOUNT ACTUATOR BRACKET
Fasten the actuator bracket (item #1) to the standoff
bracket (Item #7) using [4]
1
⁄4-20 x
1
⁄2 in. (M6 x 12mm)
spinlock bolts and nuts (Items #4 and 5). Use outer
four holes of the actuator bracket (Item #2).
NOTE: The mounting bracket may be attached in three
positions: parallel with the duct, perpendicular up
from the duct, or perpendicular down from the duct.
Choose a position that offers the most clearance for
the application.
3. FAIL POSITION
If fail position is closed, make sure damper blades are
fully close and ensure blade seals are compressed
prior to tightening the actuator clamp to the damper
extension pin or jackshaft.
4. MOUNTING ACTUATOR
Install the actuator (item #6) over the damper drive
shaft and tight against the actuator bracket (Item
#1). Install [1] #10-24 x .375 shoulder bolts (Item #2)
through lugs on actuator and through the holes in the
back of the actuator bracket (Item #1). Secure with [2]
#10-24 nuts (Item #5).
5. Secure the actuator (Item #6) to the drive shaft by
tightening the set screws on the actuator collar.
5. The wiring illustration identifies actuator electrical
requirements and connection (see Figure 2). Wiring
must comply with all applicable electrical codes.
6. Apply power to the actuator. The damper blades
should fully open or close and return to the fail
position when power is disconnected.
