TROUBLESHOOTING
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.
