ACTUATOR INSTALLATION — To install the actuator:
1. Align actuator so that the actuator linkage arm will have
enough clearance for full range of motion. Refer to
Fig. 34-37. Align center line of the actuator as close to the
centerline of DR4 as possible. See Fig. 36 and 37. Use at
least 4 self-drilling screws to mount directly to top of unit.
2. Place linkage arm assembly (linkage arm and swivel nut
arm) onto DR4 as shown in Fig. 36 and 37. Do not tight-
en to DR4 as adjustments need to be made.
3. Place linkage rod between actuator arm and linkage arm
on DR4. See Fig. 36. Linkage rod may need to be cut to
length. Ensure actuator arm and linkage arm are parallel.
4. Ensure linkage assemblies are properly secured as shown
in the linkage assembly instructions sent with the unit.
5. Open one set of dampers to 100% open and the other to
100% closed. Ensure actuator motion will operate as
needed and tighten all linkages, swivel assemblies, and
linkage rods into place.
6. Ensure actuator motion opens and closes damper assem-
blies fully. If not, adjust settings of linkage arm, actuator
arm, swivel nut assemblies, and linkage rods one at a time
until full operation is achieved.
