85051B 3-5Use, Maintenance, and Care of the DevicesCleaning ConnectorsCleaning Connectors1. Use Compressed Air or NitrogenClean connectors are essential for ensuring the integrity of RF andmicrowave coaxial connections.Use compressed air (or nitrogen) to loosen particles on the connectormating plane surfaces.You can use any source of clean, dry, low-pressure compressed air ornitrogen that has an effective oil-vapor filter and liquid condensation trapplaced just before the outlet hose.Ground the hose nozzle to prevent electrostatic discharge, and set the airpressure to less than 414 kPa (60 psi) to control the velocity of the airstream. High-velocity streams of compressed air can cause electrostaticeffects when directed into a connector. These electrostatic effects candamage the device. Refer to “Electrostatic Discharge” on page 1 foradditional information.2. Clean the Connector ThreadsUse a lint-free swab or cleaning cloth moistened with isopropyl alcohol toremove any dirt or stubborn contaminants on a connector that cannot beremoved with compressed air or nitrogen. Refer to Table 6-3 on page 4 fora part number for cleaning swabs.a. Apply a small amount of isopropyl alcohol to a lint-free cleaningswab.b. Clean the connector threads.Always use protective eyewear when using compressed air ornitrogen.Keep isopropyl alcohol away from heat, sparks, and flame. Store in atightly closed container. It is extremely flammable. In case of fire, usealcohol foam, dry chemical, or carbon dioxide; water may be ineffective.Use isopropyl alcohol with adequate ventilation and avoid contact witheyes, skin, and clothing. It causes skin irritation, may cause eye damage,and is harmful if swallowed or inhaled. It may be harmful if absorbedthrough 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.
