FAN BLADE SETTING DIMENSIONS
Shown in the drawing below 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 check and blade adjusted in or out
on the motor shaft accordingly.
REMOVAL OF THE FAN SHROUD
1. Disconnect all power to unit.
2. Remove the screws holding both grilles, one on each
side of unit, and remove grilles.
3. Remove screws (9) holding fan shroud to condenser
and bottom.
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.
