Air Compressor Manual
Operating Instructions
8. Install appropriate ASME code safety valves and make sure piping system is equipped with adequate
condensate drains. See gure 4.
9. Make sure any tube, pipe or hose connected to the unit can withstand operating temperatures and retain
pressure.
10. Never use reducers in discharge piping. Keep
all piping and ttings the same size in the
piping system.
11. For permanent installations of compressed
air systems, determine total length of system
and select correct pipe size. Make sure
underground lines are buried below frost line
and avoid areas where condensation could
build up and freeze.
12. Test entire piping system before underground
lines are buried. Be sure to nd and repair all
leaks before using compressor.
Never install a shut-off valve such as a glove or gate valve, between the
pump discharge and the air tank unless a safety valve is installed in
the line between valve and pump.
