Visual Inspection
Visual inspection and, if necessary, cleaning should be done every time a connection is
made. Inspect mating surfaces for dirt, dust, foreign particles, or scratches, which can
degrade device performance. A damaged mating surface can damage any good surface
connected to it. If necessary, clean all mating surfaces.
Cleaning the Mating Plane Surfaces
1. Use Compressed Air or Nitrogen
WARNING Always use protective eyewear when using compressed air or
nitrogen.
Use compressed air (or nitrogen) to loosen particles on the mating plane surfaces. Clean
air cannot damage a device or leave particles or residues behind.
You can use any source of clean, dry, low-pressure compressed air or nitrogen that has
an effective oil-vapor filter and liquid condensation trap placed just before the outlet
hose.
Ground the hose nozzle to prevent electrostatic discharge, and set the air pressure to
less than 414 kPa (60 psi) to control the velocity of the air stream. High-velocity
streams of compressed air can cause electrostatic effects when directed into a device.
