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 sup-
ply 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 con-
densate disposal. See Fig. 3 for condensate connections for
each unit position.
Typical positioning and alternate return air locations are
shown in Fig. 3. Alternate return air locations can be used by
moving the unit panel from the alternate return air location
to the standard return air location.
IMPORTANT: Do NOT attempt to install unit with
return air entering top panel of unit. Condensate will
not drain from unit.
