on the motor shaft accordingly.
REMOVAL OF THE FAN SHROUD

assembly out the left side of the unit.
6. Service motor/fan as needed.

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” from compressor) as shown in Table 7.
The suction line temperatures in Table 7 are based upon
80° F dry bulb/67° F wet bulb (50% R.H.) temperature
and rated airflow across the evaporator during cooling
cycle.
