Use, Maintenance, and Care of the Devices
Cleaning Connectors
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 connector. These electrostatic effects can
damage the device. Refer to “Electrostatic Discharge” on page 3-1 for
additional information.
2. Clean the Connector Threads
Use a lint-free swab or cleaning cloth moistened with isopropyl alcohol to
remove any dirt or stubborn contaminants on a connector that cannot be
removed with compressed air or nitrogen. Refer to Table on page 6-4 for a
part number for cleaning swabs.
a. Apply a small amount of isopropyl alcohol to a lint-free cleaning
swab.
b. Clean the connector threads.
c. Let the alcohol evaporate, then blow the threads dry with a gentle
stream of clean, low-pressure compressed air or nitrogen. Always
completely dry a connector before you reassemble or use it.
3. Clean the Mating Plane Surfaces
a. Apply a small amount of isopropyl alcohol to a lint-free cleaning
swab.
b. Clean the center and outer conductor mating plane surfaces. Refer
to Figure 2-1 on page 4 . When cleaning a female connector, avoid
snagging the swab on the center conductor contact fingers by using
short strokes.
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.
