Titus QCV IOM - Manual

QCV-IOM-1.0 2-28-13
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.
