REFRIGERATION SYSTEM
Note: All 62X units are equipped with lead circuit digital compressors and hot gas reheat (HGRH). Additionally, some 62X units
are equipped with a liquid subcooling reheat on all circuits and lag circuit digital compressor. When checking refrigeration system
performance, HGRH must be disabled, digital compressors must be manually forced to 100% operation, and the liquid subcooling
circuit(s) must be active.

Note: All 62X units are charged at factory environmental conditions. Refrigerant charge may need to be adjusted based on local en-
vironmental and application conditions. Adjust charge as needed to achieve 10-12°F of subcooling with HGRH disabled, all com-
pressors operating at 100%, and all subcooling circuits active (if equipped).
