REMOVAL OF FAN SHROUD
1. Disconnect all power to the unit.
2. Remove the screws holding both grilles, one on each
side of unit, and remove grilles.
3. Remove screws holding fan shroud to condenser and
bottom. Nine (9) screws.
4. Unwire condenser fan motor.
5. Slide complete motor, fan blade, and shroud
assembly out the left side of the unit.
6. Service motor/fan as needed.
7. Reverse steps to reinstall.
REFRIGERANT CHARGE
The correct system R-22 charge is shown on the unit
rating plate. Optimum unit performance will occur with
a refrigerant charge resulting in a suction line
temperature (6" from compressor) as shown in Table 7.
The suction line temperatures in Table 7 are based upon
80°F dry bulb / 67°F wet bulb (50% R.H.) temperature
and rated airflow across the evaporator during cooling
cycle.

FAN BLADE SETTING DIMENSIONS
Shown in Figure 16 are the correct fan blade setting
dimensions for proper air delivery across the outdoor
coil.
Any service work requiring removal or adjustment in
the fan and/or motor area will require that the
dimensions below be checked and blade adjusted in or
out on the motor shaft accordingly.
