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.
TROUBLESHOOTING
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 right 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 6.
The suction line temperatures shown in Table 6 are
based upon 80°F dry bulb/67°F wet bulb (50 percent
R.H.) temperature and rated airflow across the
evaporator during cooling cycle.
