Belimo and Honeywell models

Installation, Operation, and Maintenance Instructions

These instructions apply to the internal or external field replacement of mounting hardware for direct drive
actuators (Belimo and Honeywell [except MS7505 and MS8105 series] ) on Greenheck control dampers when
they are duct mounted or sleeved.

WARNING

!

Equipment Damage or Electrical Power Hazard.
Line voltage can cause death or serious injury
and short circuit equipment. Disconnect power
supply before installation.

⁄16 in., (1) 3⁄8 in., (1) 9⁄16 in.

3

⁄8, 7⁄16, 9⁄16 in. deepwell socket

(1) 1⁄8 in. Allen wrench,

(1) .203 dia. drill bit

Steel Airfoil Blade

Instructions

1. Have damper in desired fail position.

2. Drill (2) 0.203 inch holes in the first blade (when one
or two blade damper) or third blade (more than a two
blade damper) at a location as shown above for the
blade type you have.

3. Attach blade drive lever (item #13) using two fasteners
(see list above based on blade type). Note: Shaft (item
#4) needs to be centered with the centerline of the
blade.

4. Fasten actuator bracket (item #1) to the left jamb of
damper frame using (1) thread cutting screw in top tab
of bracket (0.203 in. hole is required). Note bottom tab
does not get a fastener. Install (2) 1/4 -20 x 1/2 studs
(item #15) and nuts (item #14) through holes in damper

frame. Snap bearing (item #12) into internal actuator
bracket.

5. Slide 1/2 in. diameter shaft (item #4) slightly through
the anti-rotation bracket (item #5). Install crankarm
(item #3) and drive link (item #2) onto the 1/2 in.
diameter shaft (item #4) and install e-clip (item #6) to
lock drive link (item #2) on the crankarm (item #3).After
the crankarm is installed, slide 1/2 in. shaft through the
bearing (Item #12).

6. Install shoulder bolt (items #8 or 10) to the anti-rotation
bracket (item #5) using nut (item #9 or 11). Bolt
location will vary depending on the actuator model.

7. Slide the anti-rotation bracket (item #5) over the 1/2
in. shaft. Fasten to actuator bracket (item #1) using
thread cutting screws (item #7). Attach actuator to

anti-rotation bracket assembly (item #5). Tighten the
actuator onto the shaft (item #4).

8. Connect drive link (item #2) to blade drive lever (item
#13) using e-clip (item #6). For fail close, position the
blades in the closed position and the actuator in its fail
position. For fail open, position the blades in the open

position and the actuator in its fail position. Tighten
the crankarm to the 1/2 in. shaft.

9. Connect all electrical leads to the actuator. Apply
power to the actuator. The damper blades should
rotate to the power position and return to the fail
position when power is disconnected.

Instructions

1. Have damper in desired fail position.

2. Drill (2) 0.203 inch holes in the first blade (when one
or two blade damper) or third blade (more than a two
blade damper) at a location as shown above for the
blade type you have.

3. Attach blade drive lever (item #12) using two fasteners

of bracket (0.203 in. hole is required). Note: bottom tab
does not get a fastener. Install (2) 1/4 x 20 x 1/2 stud
bolts (item #14) and nuts (items 13) through the frame.

5. Slide 1 in. diameter shaft (item #4) slightly through the
anti-rotation bracket (item #5). Install crankarm (item
#3)and drive link (item #2) onto the 1 in. diameter shaft
(item #4) and install e-clip (item #6) to lock drive link
(item #2) on the crankarm.

6. Install shoulder bolt (item #8 or 10) to the anti-rotation
bracket (item #5) using nut (item #9 or 11). Bolt
location will vary depending on the actuator model.

7. Install anti-rotation bracket (item #5) to actuator
bracket (item #1) using thread cutting screws (item #7).
Attach actuator to anti-rotation bracket assembly (item
#5). Tighten the actuator onto the shaft.

8. Connect drive link (item #2) to blade drive lever (item
#12) using e-clip (item #6). For fail close, position the
blades in the closed position and the actuator in its fail
position. For fail open, position the blades in the open
position and the actuator in its fail position. Tighten
the crankarm to the 1/2 in. shaft (item #4).

9. Connect all electrical leads to the actuator. Apply
power to the actuator. The damper blades should
rotate to the power position and return to the fail
position when power is disconnected.
