READ INSTRUCTIONS BEFORE INSTALLING
HELPFUL HINTS
• When installing multiple dampers, before
installing all dampers, wire each damper
individually and cycle to confirm damper
operation.
• Ensure all ducts are round and the damper
can move feely from open to closed once inside
the duct.
• Ensure the damper s u-frame is in-line with
the center of the duct.
• DO NOT OVER TIGHTEN the screws when
securing the damper to the duct. Make sure
the U-Channel seal and ends just meet the
outside of the duct.
CHECKOUT
To checkout the operation of the
dampers place 24V across terminals
M1 and M4, the damper will open
and the Green LED will light at the
end of the cycle. Place 24V to
terminals M1 and M6 and the
damper will close and the Red LED
will light at the end of the cycle. All
dampers are 100% factory tested.
TROUBLESHOOTING
After performing the checkout of
the damper, check the motor
terminals for 24V across terminals M1
and M4 if the damper is supposed
to be open, and M1 and M6 if the
damper is to be closed. If power is
not at the proper terminals, check
the wiring and control panel for
power.
