FIGURE 10
TROUBLESHOOTING
The suction line temperatures in table above are based upon
80° F dry bulb / 67° F wet bulb (50% R.H.) temperature and
rated airflow across the evaporator during cooling cycle.
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 6.

FAN BLADE SETTING DIMENSIONS
Shown in Figure 10 is the correct fan blade setting
dimension 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.
