Process tubes are installed in compressor housings at the factory as an aid in factory dehydration and charging. These can be used in place of the suction tube if they are of the same diameter and wall thickness as the suction tube.
Standard discharge tubing arrangements for Tecumseh hermetic compressors are shown in Fig. 9-67. Discharge tubes are generally in the same position within any model family. Suction and process tube positions may vary.
