Prerequisite
The actuator is shipped from the factory with a 5°
pre-load to ensure tight close-off of the damper. To
release the pre-load, press the PUSH button before
mounting the actuator.
Installation
NOTE:
You must place the actuator on the
damper shaft so that the front of the
actuator is accessible. The label and the
manual override button are on the front
side.
1. Place the actuator on the damper shaft with the
front of the actuator accessible. The label and
the manual override button are on the front side.
2. For the EN221B2x and EN310B2x only:
Determine the rotation of the damper shaft. Set
the direction of rotation arrow to match the
rotation.

3. For all models: See Figure 3 and Figure 4 for
clockwise-to-open (CW) installation. See Figure
5 and Figure 6 for counterclockwise-to-open
(CCW) installation.
