HORIZONTAL RIGHT-HAND DISCHARGE
APPLICATION
Use the following procedures to congure the unit for hor-
izontal right-hand discharge operations:
NOTE – For horizontal applications, a secondary drain
pan is recommended. Refer to local codes.
1 - Before operating the unit, remove access panels
and the horizontal drip shield (-060 model) and the
corrugated padding between the blower and coil
assembly. Discard the corrugated padding.
2 - Install the horizontal shield on the front edge of the
horizontal drain pan as illustrated in gure 2.
3 - No further adjustment is necessary. Set unit so that
it is sloped 1/4" towards the drain pan end of the
unit.
4 - If the unit is suspended, the entire length of the
cabinet must be supported. If you use a chain or
strap, use a piece of angle iron or sheet metal
attached to the unit (either above or below) to
support the length of the cabinet. Use securing
screws no longer than 1/2" to avoid damaging the
coil or lter as illustrated in gure 3. Use sheet
metal screws to connect the return and supply air
plenums as required.

APPLICATION IN HIGH-HUMIDITY AREAS
For horizontal applications in high humidity areas, remove
the downow rail closest to the drain pan.
To remove rail:
1 - Remove the screws from the rail at the back of unit
and at the cabinet support rail.
2 - Remove the downow rail then replace screws.
3 - Seal around the exiting drain pipe, liquid line, and
suction line to prevent humid air from inltrating into
the unit.

IMPORTANT
When removing the coil, there is possible danger of
equipment damage and personal injury. Be careful when
removing the coil assembly from a unit installed in right-
or left-hand applications. The coil may tip into the drain
pan once it is clear of the cabinet. Support the coil when
removing it.
