NOTE
(−068 Model Only)
Before operating the unit,
remove access panels and the horizontal drip shield and
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.
NOTE
(−068 Model Only)
Install the horizontal shield on
the front edge of the horizontal drain pan as illustrated in
figure 2.
1. No further adjustment is necessary. Set unit so that it is
sloped 1/4 inch (6.35mm) towards the drain pan end of
the unit.

2. 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 inch
(12.7mm) to avoid damaging the coil or filter as
illustrated in figure 3. Use sheet metal screws to
connect the return and supply air plenums as required.
HORIZONTAL RIGHT−HAND DISCHARGE
APPLICATION IN HIGH HUMIDITY AREAS
For horizontal applications in high humidity areas remove
the downflow 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 downflow rail then replace screws.
3. Seal around the exiting drain pipe, liquid line, and
suction line to prevent humid air from infiltrating 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.

APPLICATION
Use the following procedures to configure the unit for
horizontal left−hand discharge operations:
NOTE For horizontal applications, a secondary drain
pan is recommended. Refer to local codes.
NOTE
(−068 Model Only)
Remove access panels and
horizontal drip shield 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.)
