E−Horizontal Left−Hand
Discharge Application
NOTE−For horizontal applications above the ceiling, a
secondary drain pan is recommended. Refer to local
codes.
1− Remove access panels and horizontal drip shield (−068
model) from the corrugated padding between the
blower and coil assembly. Discard the corrugated
padding and the downflow drip shields from the foam
pads on top of the unit. (The shields are used for
downflow applications only.)
2− Pull the coil assembly from unit. Pull off the horizontal
drain pan.
3− Remove drain plugs from back drain holes on
horizontal drain pan and re-install them on front holes.
4− Rotate drain pan 180
_
front to back and install it on the
opposite side of coil.
5− Remove screws from top cap. Remove horizontal drip
shield screw located in the center of the back coil end
seal. See figure 26.
6− Rotate horizontal drip shield 180
_
front to back.
7− Remove plastic plug from left hole on coil front end
seal and re-install plug in back hole. Re-install
horizontal drip shield screw in front coil end seal. Drip
shield should drain downward into horizontal drain
pan inside coil.
8− Rotate top cap 180
_
front to back and align with
unused screw holes. Holes must align with front and
back coil end plates. Note that top cap has a 45
_
bend
on one side and 90
_
bend on the other.
The 90
_
bend
must be on the same side as the horizontal drain pan.
NOTE−Use extreme care when re-installing screws into coil
end plate engaging holes. Coil damage could result by
misalignment.

NOTE−For horizontal applications in
high humidity
areas
, remove the downflow rail closest to the drain pan.
To remove rail, remove screw from rail at back of unit and
at cabinet support rail. Remove downflow rail then replace
screws. Also, seal around the exiting drain pipe, liquid and
suction lines to prevent infiltration of humid air.
11− Flip access door. Knock out the portion of door for the
drain pipes and attach to the cabinet with screw
provided. Replace access door on the unit.
