Notes:
• All FAS072-150 units and FHS 072-120 units with a "M" voltage designation are triple voltage; i.e., 208/230/460-3-60.
FAS 180 units are also triple voltage in the "M" configuration unless the High Static motor option is used.
"M" voltage is not available on 2-speed indoor fan motor option.
• Single-phase 072 and 091 units designate standard motor and high static drive.

Unit Positioning

The unit can be mounted on the floor for vertical applica-
tion with return air entering the face of the unit and supply
air discharging vertically through the top of the unit. The
unit can also be applied in a horizontal arrangement with
return air entering horizontally and the supply air discharg-
ing horizontally. When applying the unit in a horizontal ar-
rangement, ensure the condensate drain pan is located at
the bottom center of the unit for adequate condensate dis-
posal. See Fig. 6 for condensate connections for each unit
position.

Typical positioning and alternate return air locations are
shown in Fig. 6. Alternate return air locations can be used
by moving the unit panel from the alternate return air loca-
tion to the standard return air location. Refer to overhead
suspension accessory drawing (Fig. 7) for preferred sus-
pension technique. The unit needs support underneath to
prevent sagging.
