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 3.
If charge quantity is in doubt, reclaim unit and recharge
to factory nameplate quantity.
The suction line temperatures in Table 3 above are
based upon 80°F dry bulb / 67°F wet bulb (50% R.H.)
temperature and rated airflow across the evaporator
during cooling cycle.
