Oil Filter
Oil filter is installed on the oil separator on the pipe that returns the oil to the compressor. The differential pres-

inlet/outlet equipped with the pressure gauge on the oil separator must be installed. If the differential pressure is
4kgf/cm 2 or above, it is recommended to disassemble the oil filter and wipe the oil filter mesh.
