37. REFRIGERANT CHARGE
The correct system R-410A charge is shown on the unit
rating plate.
Reference Table 18 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.
TABLE 18
Refrigerant Charge – Pressure Tables
The nameplate charge quantity is optimized for thermal
performance and efficiency of this self-contained
package system.
The system operating pressures in Table 18 are based
upon rated airflow across the evaporator during cooling
cycle.
Total system charge for these models can be found in
Table 1.
Low side pressure ± 2 PSIG
High side pressure ± 5 PSIG
Tables based upon rated CFM (airflow) across the evaporator coil.
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.
