TABLE 3 - UNIT EXAMPLE
Outside Air and Exhaust Air Dampers
1. Position the damper blades so that they will be closed
with the power off, which will be the dampers spring
return position. Note if the damper shaft is rotated
clockwise or counterclockwise.
2. With the actuator shaft clamp tightened to the damper
jackshaft, and the damper shaft completely rotated
to its proper position, manually operate the actuator
to its fully actuated position, using the crank arm
provided with the actuator.
3. Release the spring to allow the damper to go back
to its original position, which will verify the actuators
spring rotation and stroke.
4. Set the damper actuators rotation selector switch to
the proper rotation required to actuate the damper.
The damper actuator will always be opposite the
spring return rotation.
Energize Fan Motors
Use the following instructions to energize the fan motors:
1. Observe the fan(s) for smooth operation.
2. Check the motor nameplate for the full load amp
(FLA) rating.
3. Check the current draw of each leg of each motor.
