Condensate Drain
The condensate drain hose is routed down from the
evaporator drain pan on the right side of the unit into
the compressor compartment. There are three locations
that the drain can exit the cabinet. For a stand pipe
type of drain, the drain hose can exit the rear of the
cabinet. There is adequate hose length to reach the
floor on the right-hand side of the unit.
If the drain is to be hard plumbed, there is a 3/4" pipe
connection located on the right-hand cabinet side near
the rear and one on the cabinet rear panel. In these

installations, the drain tube is to be slipped over the
pipe connection inside of the cabinet.
See Figures 11A, 11B and 11C.
NOTE: Whichever type of drain connection is used, a
"P" trap must be formed.
The side drain requires a water trap for proper drainage
(see Figure 11A). The drain can be routed through the floor
or through the wall. If the drain is to be routed through an
unconditioned space, it must be protected from freezing.
The drain line must be able to be removed from the unit
if it is necessary to remove the unit from the wall.

TRAP
The rear drain can be used where there is a distance of
4 1/2" available between the unit and wall to install a
trap (see Figure 11B). The trap cannot extend beyond
the edge of the unit or it will interfere with the wall
mounting bracket. The drain can be routed through the
floor or through the wall. If the drain is routed through
the wall, the drain line must be positioned such that
it will not interfere with the sleeve flange or the grille
(see Figure 11C). If the drain is to be routed through
an unconditioned space, it must be protected from
freezing.
