E)Install a new O-ring on the seal cover, making sure the O-ring is placed in the O-ring groove and not the oil gallery groove. Lubricate both seal faces with clean compressor lubricating oil.

F)Carefully install the seal cover on the compressor shaft, evenly tightening the bolts to the recom- mended torque values.

G)Install the coupling and coupling guard. The unit can then be evacuated and leak checked.
