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 checked and blade adjusted in or out on the motor shaft accordingly.

The suction line temperatures in Table 8 are based upon 80ºF dry bulb/67ºF wet bulb (50 percent R.H.) temperature and rated airflow across the evaporator during cooling cycle.

REMOVAL OF FAN SHROUD

1.Disconnect all power to unit.

2.Remove the screws holding both grills – one on each side of unit – and remove grills.

3.Remove screws holding fan shroud to condenser and bottom – 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 inches from compressor) as shown in Table 8.
