ABSTRACT:
A method of installing a removable inlet port filter plate having a replaceable filter between a compressor inlet port and a suction hose assembly is taught. The inlet port filter plate includes a main body and mounting surfaces for attachment between the compressor and the suction hose assembly or between the compressor and the compressor hose block. The main body defines a passage that allows for refrigerant flow through a filter which is positioned in the passage. In one preferred embodiment the diameter of the filter is greater than the inside diameter of the compressor inlet port. In another preferred embodiment the diameter of the filter is greater than the inside diameter of the suction hose assembly outlet port.
