Functions of oil check valve: During after-sale maintenance, the oil check valve can be used to
extract lubricating oil samples, which are further detected to analyze the oil quality in the system.
The oil check valve can also serve as the inlet for lubricating oil charging. Before extracting
lubricating oil from the system, stop the system for at least 12 hours and release refrigerant. Do not
extract oil until system‘s pressure drops to 0.05MPa (7.25psi) or below; otherwise, overheat oil may
burn the operator.
Functions of low-pressure check valve: It is mainly used for low pressure detection of the system
and refrigerant charging during after-sale maintenance.
