FAN BLADE SETTING DIMENSIONS

Shown in the drawing in Figure 14 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.

REMOVAL OF FAN SHROUD

1. Disconnect all power to 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  –  (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
Table 7.

The suction line temperatures in Table 7 are based upon
80ºF dry bulb/67 degrees F wet bulb (50 percent R.H.)
temperature and rated airflow across the evaporator
during cooling cycle.
