Cooling System Performance
For maximum performance of the cooling system, operat-
ing temperatures and pressure should be checked.
Subcooling should be determined at Standard ARI test
conditions of 82°F outdoor and 80°F indoor dry bulb/67°F
wet bulb. If subcooling measured deviates from values
found in Table 4, refrigerant charge should be adjusted
accordingly for maximum performance.
