Installation
When planning the installation, allow ample clearance for
maintenance and service. Ensure the location is protected
from rain and snow. The following steps provide basic
instructions to install a damper motor.
1. Position damper motor on mixing box where
mounting is desired.
Note: Motor placement may restrict crank arm
rotation. Position motor to allow widest range
of crank arm rotation, see Figure 3.
2. Use the damper motor holes as guides and
drill four holes into mixing box.
3.
Secure the damper motor to mixing box using
four screws. Figure 4 shows a typical damper
motor to mixing box installation.
Note: Possible 90 degree arm rotation, based on
motor positioning.
