4. Installation and Piping
4-4 Cautions of Piping
1. General piping
When connecting a pipe to the main air pipe,
connect a flange or union to the compressor’s
discharge pipe to facilitate the repair, maintenance
and disassembly of the compressor
5. In case of a vertically upright pipe, give a
distance about 600mm and more from the cover
surface considering the repair works
6. In case pipes from compressors join to the main
pipe, connect them upright to avoid the
backward drain.

2. By attaching a ball, valve or similar device on the discharge
pipeline, make a valve closed when it stops for a long time
and prevent moisture from flowing backward
3. If the piping contains a concave or vertically
upright pipe, attach a drain valve on the
bottom.
4. Open the drain valve when stopping the
compressor to discharge the condensed water.
