Use, Maintenance, and Care of the Devices
Cleaning the Mating Plane Surfaces
Cleaning the Mating Plane Surfaces
1. Use Compressed Air or Nitrogen
Clean mating surfaces are essential for ensuring the integrity of the waveguide.
WARNING
Always use protective eyewear when using compressed air or
nitrogen.
Use compressed air (or nitrogen) to loosen particles on the mating plane surfaces.
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 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. These
electrostatic effects can damage the device. Refer to
“Electrostatic Discharge” on
page 3-2 for additional information.
WARNING Keep isopropyl alcohol away from heat, sparks, and flame. Store in a
tightly closed container. It is extremely flammable. In case of fire, use
alcohol foam, dry chemical, or carbon dioxide; water may be
ineffective.
Use isopropyl alcohol with adequate ventilation and avoid contact
with eyes, skin, and clothing. It causes skin irritation, may cause eye
damage, and is harmful if swallowed or inhaled. It may be harmful if
absorbed through the skin. Wash thoroughly after handling.
In case of spill, soak up with sand or earth. Flush spill area with
water.
Dispose of isopropyl alcohol in accordance with all applicable
federal, state, and local environmental regulations.
2. Clean the Mating Plane Surfaces
a. Apply a small amount of isopropyl alcohol to a lint-free cleaning swab.
b. Clean the mating plane surfaces.
c. Let the alcohol evaporate, then blow the surface dry with a gentle stream of clean,
low-pressure compressed air or nitrogen. Always completely dry the surfaces before
you use it.
3. Inspect the Mating Surfaces
Inspect the mating surface to make sure that no particles or residue remain. Refer to
“Visual Inspection” on page 3-3 .
