5. Place a linkage arm onto DR1 and DR2. See Fig. 42 and

43 for proper positioning. Ensure that swivel joints are

fully extended to the end of the linkage arm and tighten.

6. Insert linkage rod into swivel joints and tighten. Linkage

rod may need to be cut down to size. Linkage arms

should be parallel.

7. Ensure one set of dampers are fully open and the other

fully closed. Adjust linkage assembly to allow travel

without interference and tighten to DR1 and DR2.

8. The actuator should now be able to power the dampers

fully open and fully closed without interference. Adjust

linkage assemblies as needed.

MIXING BOX LINKAGE INSTALLATION (Sizes 04-

17) — To install the mixing box linkage assembly (sizes

04-17):

1. Check for correct number of parts:

3 – Linkage rods
6 – Linkage arms

6 – Swivel joints

NOTE: A

in. box end wrench and/or socket will be

needed for linkage installation.

2. An alternate field-supplied actuator may be installed

directly on the damper shaft if required. If a factory-

supplied actuator is ordered for the mixing box, refer to

Mixing Box Actuator section on page 23.

3. Orientate actuator to avoid interference with linkage

assembly. Refer to Fig. 44 and 45.

4. Ensure dampers are fully closed or open depending on

application, and secure actuator to shaft. Actuator should

open and close dampers fully. Adjust actuator as needed.

5. Place a linkage arm onto DR3 and DR2. See Fig. 46 and

47. for proper positioning. Ensure that swivel joints are

fully extended to the end of the linkage arm and tighten.

6. Insert linkage rod into swivel joints and tighten. Linkage

rod may need to be cut down to size. Linkage arms

should be parallel. Assembly should still be loose on

damper rods. This will be linkage assembly no. 1.

7. Place linkage arm onto DR1 and DR2. Ensure swivel

joints are fully extended to the end of the linkage arm and

tighten.

8. Insert linkage rod into swivel joints and tighten. Linkage

rod may need to be cut down to size. Linkage arms

should be parallel.

9. Ensure dampers are fully open or closed and tighten link-

age arms to damper rods. Linkage assembly should be

able to open and close dampers fully without interference.

Adjust accordingly.

10. Place linkage arm onto DR3 and DR4. Ensure swivel

joints are fully extended to the end of the linkage arm and

tighten.

11. Insert linkage rod into swivel joints and tighten. Linkage

rod may need to be cut down to size. Linkage arms

should be parallel.

12. Ensure dampers are fully open or closed and tighten link-

age arms to damper rods. Linkage assembly should be

able to open and close dampers fully without interference.

Adjust accordingly.

13. Ensure one set of dampers is fully open and the other ful-

ly closed. Adjust linkage assembly no. 1 to allow travel

without interference and tighten to DR2 and DR3.

14. The actuator should now be able to power the dampers

fully open and fully closed without interference. Adjust

linkage assemblies as need.
