Unit Installation

Due to their weight, theVAV 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.

Recommendations

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.
