INSTALLATION INSTRUCTIONS

Installing the RDV/RDVQ Terminal Unit
The basic RDV is light enough that it can be supported by the
ductwork in which it is installed. The RDVQ is supplied with
silencers and should be supported directly. Use the support
method prescribed for the round duct in the job specifications.
For optimum performance there should be a minimum
NOTE:
of three duct diameters of straight inlet duct, same size as the
inlet, between the inlet and any transition, take off or fitting.
The assembly should be mounted right side up. It should be
level within ±10 degrees of horizontal, both parallel to the
air flow and at right angles to the air flow. The side of the
assembly is labelled with an arrow indicating UP. Do not mount
the control side of the assembly tight to a wall, pipe or other
obstruction. Allow sufficient room for access to the controls
If the RDV/RDVQ is mechanically fastened to the duct work an
approved duct sealer should be used to seal all connections.
Damper rotation is always clockwise to the open position.
An identification mark on the end of the shaft indicates the
damper position.
The air volume ranges listed are recommended for optimum
performance. A minimum value of zero is also acceptable if no
heating coils are attached.
Selection of air flow limits below the listed values is not
recommended. Stability and accuracy may not be acceptable
at lower than recommended air flow limits. The actual
performance will vary depending on the terminal unit controls
supply.

NOTE: Factory calibrated controls must be selected
within the above flow range limits. A minimum value
of zero is also available. When an auxiliary flow
setting is specified, the value must be greater than
the minimum setting and within the range limits.
On controls mounted by Price but supplied by others, the air
volume ranges are guidelines only.
Selection of air flow limits below the listed values is not
recommended. Stability and accuracy may not be acceptable
at lower than recommended air flow limits. The actual
performance will vary depending on the terminal unit controls
supplied.
