checking, cleaning, or repairing the equipment.
• Relieve the pressure before cleaning, checking
or repairing. Follow Pressure Relief Proce-
dure, above.
• Check system at least once per shift to ensure
proper drainage.

installed upstream of the coalescing filter to
remove 3 micron and larger size particles and sep-
arate large droplets of moisture from the air line.
