NOTE: See the data sheet for mounting accessories.
1. Connect the actuator to the damper shaft by one
of the following two methods:
• If the actuator has a supplied crank arm
linkage, check that the ball joint is positioned
for the correct rotation. See the "A" and "B"
dimensions on the chart above for standard
rotations. Slide the crank arm on the damper
shaft and tighten the set screws.
• If the actuator does NOT have a supplied
linkage, connect the damper's blade clip or
drive arm with a clevis pin and cotter pin.
2. Position the damper for its "normal" position.
3. Mount the actuator to the side of a VAV terminal
using the mounting holes in the bracket.
4. Rotate the actuator body (on metal bodies only,
not plastic) so that the air connection is in the
desired location.
5. Check that the linkage will not bind as the shaft
extends and retracts.
