NOTES:
1. Bolt sizes and thread pitch: Compressors are built
using English unit bolts. The bolts have no exact metric
equivalents. Therefore, to prevent possible cross-thread-
ing, loose bolts, or damage to threaded portions of the
casing, comparable metric measurements are not
included.
2. The 13 and 16 Cfm service compressors are made with
dual suction ports.
