Note: The actuator can be mounted in any orientation.
1. Position the actuator onto the drive pin extension so that the actuator
sits against the duct.
2. Use of the actuator’s center mounting slots with the isolation
grommets is the preferred mounting arrangement. If the duct or wall
is less than 16 gauge (0.06 inch or 1.5 mm), order and use the
Universal Mounting Bracket (D-3153-105).
Note: Because of eccentric motion of the actuator that occurs when using
shafts smaller than 10 mm (0.394 inch) square or 1/2 inch
(12.5 mm) round, use of the isolation grommets in the center
mounting slot is required.
3. Mark the location of the actuator's top and bottom mounting slots on
the duct or wall.
4. Remove the actuator and set aside.
5. Drill 5/32 inch (4 mm) holes in the duct or wall at the marked
locations.
