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.
