Mounting
These actuators are designed to mount on a standard

shaft using the optional HFO-0011 adaptor.
Standard Instructions
1. Slide the actuator directly onto the 1/2 in.
diameter damper shaft. The shaft must extend a
minimum of 1-3/4 in. from the mounting surface.
(For a 3/8 in. shaft, see HFO-0011 Adaptor on
page 1.)
2. Place the non-rotation bracket (supplied) on
the non-rotation tab (see illustration). Leave a
gap of 1/8" between the boom surface of the

surface using (2) #8 or #10 self-tapping screws
(not included).
4. Depress the gear disengagement buon and:
A. Rotate the drive hub until the indicator stops
at the “90” mark if the damper is clockwise
(CW) to close.
B. Rotate the drive hub to the “0” mark if the
damper is counterclockwise (CCW) to close.
5. Position the damper to full open.
6. Torque the two 5/16-18 set screws 75 to 85 in-lb.
7. Depress the gear disengagement buon and
rotate the drive hub/damper to the closed
position.
