Removable Coupler
If the damper shaft is less than 81.3 mm (3.2 in.) long,
the coupler must be inserted in the face of the actuator
closest to the damper.
If the damper shaft is shorter than 43.2 mm (1.7 in.), a
shaft extension is required to mount the actuator.
To change the coupler's position, refer to Figure 3 and
proceed as follows:

1. Pull the locking clip off the coupler, and remove
the coupler from the actuator.
Note: Proceed to the Rotation Range section for a
rotation range less than 90°.
2. Reinsert the coupler into either the CW or CCW
face of the actuator (determined by the shaft
length discussed earlier in this section).
Note: The coupler splines (shown in Figure 3) are
designed to prevent insertion of the coupler at the
wrong end of the rotation range.
IMPORTANT:
For 0 to 93° rotation, the coupler
must fit as closely as possible to, but not on top of,
the metal plate at the spring return position.
3. Snap the locking clip securely into the coupler
groove to retain the coupler in the actuator.

Mounting
The M9206-Bxx-1S actuators can be mounted in any
convenient orientation. The actuators can be installed
on a 10 to 16 mm (3/8 to 5/8 in.) round shaft or a
10 to 14 mm (3/8 to 9/16 in.) square shaft. If the shaft
extends less than 81.3 mm (3.2 in.), refer to the
Removable Coupler section.
To mount the actuator, proceed as follows:
1. Bend or cut the anti-rotation mounting bracket to fit
the damper frame or duct as shown in Figure 4.
(The bracket can be bent to fit a round damper.)

Positions
2. Slide the actuator onto the damper shaft.
3. Position the anti-rotation mounting bracket into the
slot at the bottom of the actuator. Use the most
appropriate pair of notches in the bracket tab
(Figure 4).
IMPORTANT:
The tab on the anti-rotation
mounting bracket must fit midpoint in the actuator
slot. This prevents actuator binding and premature
wear and makes actuator removal easier.
4. Refer to the dimensions in Figure 5 to ensure the
correct placement of the anti-rotation mounting
bracket.
