Receiving Inspection
After unpacking the assembly check it for
shipping damage. If any shipping damage is
found, report it immediately to the delivering
carrier. During unpacking and installation do
not handle by the inlet velocity sensor or the
control package.
Determine Position of the
Control Enclosure
The control enclosure can be installed on
either side of the ductwork by flipping the VAV
unit over 180 degrees. Unit with mercury
contactors, pneumatic controls, and digital
controls (DDC) need to be inspected before
installing.
Important: Unit with mercury contactors is
position sensitive. As a result, before installing
unit with mercury contactors, inspect the
position of the mercury contactors in the
control enclosure. Mercury contactors must be
heading up 90 degrees vertically. If they are
heading down, unscrew the mercury contactors,
rotate 180 degrees, and reinstall them.
If unit is equipped with pneumatic controls, it
should be mounted right side up and level
within ±10 degrees of horizontal, and parallel to
the airflow. The first letter in the model number
indicates control type (P is for pneumatic). If
the unit is mounted upside down, the controller
will have to be repositioned, re-piped, and
recalibrated. Analog control units (A-analog
model number pre-fix) may be installed in any
orientation. Some Digital (DDC) controls
(D-digital model number pre-fix) are position
sensitive dependent on the airflow sensor
transducer. Check with the controls
manufacturer for verification.
Supporting the Assembly
We recommend that each terminal unit be
independently supported, especially when
accessory modules, such as coils, attenuators,
silencers or multiple outlets are present.
Hanger straps may be used and screwed
directly into the sides or bottom of the unit
casing (see Fig. 1). Alternately, a carriage
made of unistrut may be used, somtimes this is
known as a trapeze setup. Support the VAV
and any accessories separately (Fig. 2). When
requested, unit is supplied with field mounted
hanger brackets for use with hanger rod up to
3/8" (9.5) dia. Hanger brackets should be
screwed into the top of the unit casing (see Fig.
3 & 4). Use the support method prescribed for
the rectangular duct in the job specifications.
