Structural Maintenance 12-15
When it stops, the flat should be on the left side of the output shaft and approximately parallel with the vertical sides of the
gear case. In this position the damper would be open. The output shaft must be in this position (damper open) when the damper
motor is being installed in the unit.
NOTE: If the damper motor assembly does not function properly, it should not be installed.
Damper Motor Installation
1. Make sure that the flat is on the left side of the damper motor output shaft (see “Damper Motor Test” earlier in this chapter).
