Bypass Damper Wiring
The interconnect cable is pre-wired to the bypass damper and may be
lengthened if necessary.
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
The bypass damper must be positioned to orient the drive shaft horizon-
tally. Failure to do this may result in drive train malfunction (see Figure
11).
IMPORTANT
It is important to note the airflow direction when installing dampers. A
label for this is present on each damper assembly.

1. Avoid high pressure turns and transitions
2. Use hard duct
3. Mount communicating Sensor/Bypass Controller
2-3 duct diameters upstream of bypass damper
The communicating sensor/bypass control is located between the supply
fan and the bypass damper in the least turbulent location possible. It is
recommended that the distance between the control and the nearest up-
stream transition be two to three equivalent duct diameters.
