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 the following table:
