REFRIGERANT CHARGE
The system is charged with R-407C. The correct
quantity 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 Table 6.
The suction line temperatures shown in Table 6 are
based upon 80°F dry bulb / 67°F wet bulb (50 percent
R.H.) temperature and rated airflow across the
evaporator coil during cooling cycle.
See page 20 for instructions in servicing units which
contain refrigerant R-407C
