Install the VariTrac Dampers

Install the VariTrac Dampers
A sketch of basic damper installation is shown in Figure 10. The damper may
be connected with hard duct or flex duct at either end.
If two bypass dampers are installed, a pigtail socket is provided on the cable
so the second damper can be plugged into the UCM.
IMPORTANT
Mounting screws must be located towards the ends of the damper when
hanging straps are used to avoid interference with the rotating damper. A
label attached to the dampers indicates the acceptable areas for mounting
screws.
IMPORTANT
It is important to note airflow direction when installing the damper. A
label for this is present on each damper assembly.
IMPORTANT
The control box on each damper must be positioned to orient the drive
shaft horizontally. Failure to do this may result in drive train malfunction.
