Operation
For CCW spring return direction, mount the actuator to
the damper shaft so that Side A of the actuator is away
from the damper as illustrated in Figure 2. With power
applied, the actuator drives CW from the 0° position,
and spring returns CCW.

Removable Coupler
The coupler may be installed on either side of the
output hub. If the damper shaft is less than 3-19/32 in.
(91 mm) long, insert the coupler in the face of the
actuator closest to the damper. If the damper shaft is
shorter than 1-5/32 in. (29 mm) long, a shaft extension
is required to mount the actuator.
