QCV Series Retrofit Terminals

Installation

To install, simply cut a rectangular opening in the side of the duct. The opening should be the height of the duct and 10 ½

inches wide as shown above. If the duct is internally lined with insulation, cut out a 1 inch wide groove of insulation down

to the sheet metal duct. The groove should be in line with the duct plate which has the mult-point center averaging velocity

sensor mounted in it. Duct sealer can now be applied to the bottom inside section of the duct, which aligns with the duct

plate. The duct plate has a 1 inch wide flange for duct sealer to be applied to the top edge as well. The flange can be used

as well for attachment to the duct with sheet metal screws. After the retrofit valve is inserted into the duct with duct sealer

on the top and bottom edges of the duct plate, the valve assembly should be firmly attached to the duct with sheet metal

screws in the mounting plate and the duct plate plate flanges. The corner reinforcing angles should be attached to the top

and bottom of the mounting plate as shown. A sealer may also be used to decrease leakage along the reinforcing angles.

The controls are now ready to be piped and activated. Please note that the valve is always installed so the damper is

down stream from the air flow sensor.
