36. REFRIGERANT CHARGE
The correct system R-410A charge is shown on the unit
rating plate.
You can reference Table 17 to validate proper system
operation (+2 psig suction, +5 psig discharge). However,
it is recommended that if incorrect charge is suspected, the
system refrigerant be reclaimed, evacuated and charged to
the nameplate charge quantity and type.

If there is any doubt as to correct operating charge being in the system, the charge should be reclaimed, system
evacuated and recharged to serial plate instruction.

The nameplate charge quantity is optimized for thermal
performance and efficiency of this self-contained package
system.
The system operating pressures in Table 17 are based
upon rated airflow across the evaporator during cooling
cycle.
Total system charge for these models can be found in
Table 1.
