Precision Suction Restrictor:
Tandem manifold compressors that have unequal
capacity sizes utilize a precision suction restrictor to
balance the oil levels in the compressors. For tandem
manifold compressors in Intellipak units, this restrictor is
placed in the compressor indicated in Table 77. When
replacing this compressor, it is imperative that the proper
restrictor is selected from those provided with the
replacement compressor.
When the compressors are restarted verify that correct oil
levels are obtained with both compressors operating.
