1. If necessary, adjust Distance A to the proper
dimension by loosening the locknut on the end
of the solenoid plunger and turning the
plunger to move the solenoid rod. Tighten the
locknut when Distance A is correct.
2. De-energize the solenoid and connect the
solenoid rod to the damper shaft.
3. Energize the solenoid and check the damper
blade to make sure that both edges contact the
damper housing. If necessary, adjust this by
loosening the solenoid mounting bolts and
moving the solenoid. Tighten the solenoid
mounting bolts when both damper blades
contact the damper housing.
4. Adjust the damper blade stops so they contact
the edges of the damper blade. This keeps the
damper from sticking closed.
5. De-energize and energize the damper several
times to make sure that the damper operates
correctly and seals properly.
6. Make sure that the damper blade rests on the
round stops when the damper is open. Adjust
the round stops if necessary.
7. Install the damper assembly in the evaporator.
