REMOVAL OF FAN SHROUD

1.Disconnect all power to the unit.

2.Remove the screws holding both grilles, one on each side of unit, and remove grilles.

3.Remove screws holding fan shroud to condenser and bottom. Nine (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-410A 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 2. If charge quantity is in doubt, reclaim unit and recharge to factory nameplate quantity.
