Unit Positioning -- The unit can be mounted on the floor for

vertical application 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 discharging horizontally. When applying the unit

in a horizontal arrangement, ensure the condensate drain pan

is located at the bottom center of the unit for adequate

condensate disposal. See Fig. 6 for condensate connections

for each unit position.
IMPORTANT: Do NOT attempt to install unit with return
air entering top panel of unit. Condensate will not drain from
unit.
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

location to the standard return air location. Refer to overhead

suspension accessory drawing (Fig. 7) for preferred

suspension technique. The unit needs support underneath to

prevent sagging.
