Specifications subject to change without notice.
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 hori-
zontally. When applying the unit in a horizontal arrange-
ment, ensure the condensate drain pan is located at the bot-
tom center of the unit for adequate condensate disposal.
See Fig. 4 for condensate connections for each unit
position.

Fig. 4 — Typical Unit Positioning
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. 4. 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 (see Fig. 5) for preferred
suspension technique. The unit needs support underneath
to prevent sagging.
Unit Isolation
Where extremely quiet operation is essential, install isola-
tors between floor and base of unit, or between ceiling and
top section of unit.
Be sure that unit is level and adequately supported. Use
channels at front and sides of unit for reference points when
leveling.
IMPORTANT: Do not bury refrigerant piping underground.
