FAN BLADE SETTING DIMENSION
REFRIGERANT CHARGE
The correct system R-407C
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 4.
The suction line temperatures in Table 4 are based upon
80°F dry bulb / 67°F wet bulb (50% R.H.) temperature
and rated airflow across the evaporator during cooling
cycle.
