est Point
Locate the Integrated Pressure Control (IPC)
and air tube on the bypass damper.
Drill hole into the side of the supply duct 2’ after
the bypass and before the 1st supply take-off.
Mount pressure supporting block over hole,
align hole in block with hole in duct. Use
provided sheet metal screws.
Install air tube into supply air duct by slipping
supplied plastic tubing into holes in support
block and duct. Slip tube 3” into the duct.
Pickup tubing fits snugly into provided hole.
Connect pressure tube from static air pickup to
Integrated Pressure Controller (port closest to
you).

Bypass Damper With
Integrated Bypass Control Setup
Run all supply dampers to the full open position
and have blower motor running at 100% fan
speed. (See Note #1)
Manually close the bypass damper by pressing in
the release lever on the motor side of the actua-
tor. With the release lever pressed, rotate the
damper actuator collar to close the damper and
release the lever to lock the damper closed.
Quick Set Option
: Turn the potentiometer on the
damper control board to the full left position and
slowly rotate RIGHT, until the “RC” RED LED turns
on. Now rotate LEFT just slightly, until RC LED
turns off. The
IPC
is ready for operation.
“RC”
RED LED means damper closing.
“RO”
GREEN LED means damper opening.
