1. Verify the opening in the duct is properly sized for the valve and installation method being used. Also verify
both ends of the duct where the valve is to be attached are true and square before attempting to install valve.
If the duct ends are not square and true, do not attempt to install valve as it will not operate properly.
2. Lift valve into position to provide
unobstructed access to the control
module, actuator and access panel.
3. Install gaskets and/or duct
sealant between the valve flanges
and companion flanges.
1. Install companion flanges (provided by others) over each end of the duct.

provide unobstructed access to
the control module, actuator
and access panel.
4. Secure both ends using tek-screws.
NOTE:
It’s acceptable to fabricate and install flanges onto the AccuValve and ductwork on location. If
flanges are fabricated on site, it’s still important to verify both ends of duct are true and square prior to
and after installing flanges, otherwise the valve will not operate properly.
Locate duct supports within 12” of each end of the valve.
