AEPF MOTOR ORIENTATION

If the unit is in the upflow position, there is no need to rotate
the motor. If the unit is in the downflow or horizontal position,
loosen motor mount and rotate motor as shown in Figure 3
Be sure motor is oriented with the female connections on
the casing down. If the motor is not oriented with the
connections down, water will collect in the motor and may
cause premature failure.

CONVERSION TO DOWNFLOW

"D" nomenclature models are factory equipped for "Dedicated
Downflow" operation and no field conversion is required.
Conversion to downflow MUST be performed in an area that
allows access to all sides prior to placing the air handler in
its final location. To prevent the evaporator coil pan from
"sweating" the DPI accessory insulation kit is to be used
when performing this conversion. NOTE: The DPI kit is not
supplied with this product and is to be purchased separately.
See Table 8 for the correct DPI kit.
