2. If installed above a finished ceiling or living space, be

sure to put a secondary drain pan under the entire unit,
and pipe the drain separately from the main condensate
drain.

3. Connect refrigerant and condensate drain connections

per the coil section installation instructions.  Ensure
refrigerant and drain lines do not interfere with service
access to the unit.

Loosen motor mount and rotate motor (See Figure 6).  Be
sure motor is oriented with the female connections on the
casing pointing down.  If the motor is not oriented with the
connections pointing down, water could collect in the motor
and cause premature failure.

NOTE: 

 After rotating motor, tighten motor mount to secure

motor.  Be sure that the gap between the motor and the
insulation is the same as it was before loosening the motor
mount.  This will ensure that the blower wheel is properly
spaced inside the blower housing.

Consult the local power company and local codes before in-
stalling this unit.  All wiring must be in accordance with the
National Electrical Code as well as all local codes.  Knock-
outs have been provided on side and top of the cabinet for
the installation of the electrical conduit.  If the knockouts on
the cabinet sides are used for electrical conduit, an adapter
ring must be used in order to meet UL1995 safety require-
