D. Adjustment Procedure for Damper Linkage of
Coils with Side-Mounted Actuators:
1. Disconnect damper motor rod at ball joints.
2. Loosen all ball joints on scissor saddle (base pan)
assembly.
3. Place scissor saddle (base pan) in an “X”
configuration. (Photo 1)
4. Adjust one end of each scissor lever to a point 11"
from casing, and clamp in that position.
5. Move damper lever arm to a position
4-1/2" from casing. (Photo 2)
6. Tighten ball joints (one on each arm) connecting
scissor saddle (base pan) arms to damper lever
arm.
7. With assembly now set, release clamps and rotate
damper lever arm until it reaches a point 1-1/2"
from casing, and clamp in this position. (Photo 3)
8. Manually check to make sure that all dampers are
fully closed around the coil.
9. Tighten ball joints (two on each side) connecting
base assembly to dampers.
10. Remove clamps.
11. Manually move scissor saddle (base pan) to check
for proper opening and closing of dampers.
12. Connect motor(s).
NOTE: Direct-coupled drive system should not
require field adjustment.
