INSTALLATION
1.
Cut a 4-inch (102-millimeter) opening in one side of the air
duct at the location selected. Ensure the opening is cut fully to
the top and bottom air duct seams.
2.
Slide the damper into the cut opening of the air duct. Ensure
the electric actuator is mounted toward the top of the air duct.
3.
Secure the damper mounting plate to the air duct with the
sheet metal zip screws provided.

CHECKOUT
To checkout the operation of the dampers the control
panel needs to be operating. It is recommended that
each damper be checked before installing into the duct.
To check the damper, plug the damper into a zone on
the control panel. Each zone of the panel has an LED
that will be
Green
when the damper is to be
open
. When
the panel LED is off, the damper will
close
and the
damper LED will turn
RED
.
All dampers are 100% factory tested with the cord
provided with each damper.
OPEN CLOSE
The damper shaft is square
however the motor has a
small triangular shape that
also indicates the position of
the damper. If the LED does
not light, this will indicate the
damper is either opening or
closing. The damper may be
closed and the LED not lit Red
as the damper may have
stopped short of full closed
due to the roundness of the
damper.

TROUBLESHOOTING
If the damper LED does not light and the motor is not moving when
plugged into the control panel, unplug and retry plugging in
again. Until the motor moves and the LED lights. Make sure
the cord is not pinched or broken.
The motor is powered by 12VDC from the panel. Check the
connector on the panel for 12VDC as shown below.
MOTOR PLUG
The power to the dampers
can be checked with a
voltmeter measuring
12VDC. Check the
and any wire the same
way by checking the
inside negative pair of
wires with the outside
positive pair of wires.
