MOUNTING (continue)

the connection coupling is attached is such as firmly hold the

operator in a position to adequately engage the anti-rotation pin

in the warm air duct. See Figure 1. for the critical dimensions.

CHECKOUT

When energized verify that the operator connection coupling

rotates in a clockwise direction (as viewed from the operator

base end) and that the damper shaft turns with the coupling. If

a saw cut is put in the opposite end of the damper shaft,

aligned with the position of the damper on the shaft, the actual

rotation of the operator - and the damper - can be readily

checked.

When de-energized the motor should rotate damper in reverse

direction by means of the integral return springs. In the

satisfied or de-energized position, the damper blade should be

fully closed or in the vertical positon when the operator is

mounted on the side of a horizontal duct.

If the motor does not operate smoothly and without hesitation

throughout the entire opening and closing stroke, examine the

damper and the shaft, for free rotation within the duct. There

should be at least a 1/4" clearance between all sides of the

damper and the duct into which it is installed.
