VAV-SVN01E-EN
Unit
Installation
Due to their weight, the VAV terminal
units should be suspended from the
uppermost ceiling, independent of the
false ceiling grid. Suspension devices
are to be supplied by the installer. Units
must be installed level and upright.
Failure to level the unit properly may
prevent proper operation of the
controls and/or terminal unit. Units are
not designed to be installed vertically.
Consequently, this will also void the UL
ratings and any warranty on the unit.
Single-Duct
Depending upon the size and weight of
the single-duct unit, it may be capable
of being supported by the ductwork
that is connected to it. No hanger
brackets are provided on these units
since the unit should be supported by
means of a hanger strap. The hanger
strap should be secured directly to the
unit casing as shown in Figure 4.
For cooling only single-duct units or
single-duct units with hot water coil, the
unt may be rotated 180° for opposite
side connections.
For units with electric heat, the unit
must be ordered from the factory
designating either right- or left-hand
connections.
Dual-Duct
Dual-duct units should be supported by
either hanger straps or by using a
threaded rod in conjunction with the
hanger brackets that are provided on
the unit. See Figure 5.
