Installation3-8 1999 Nordson CorporationAll rights reserved107 962HIssued 11/99Manual 21-19CAUTION: Apply dielectric grease to the cable bore of the gun.Without dielectric grease installed, the resistor cable or gunextension can fail due to arcing or high-voltage, coronaburn-through.NOTE: New AN-8 Plus guns are factory-assembled with the insulatingtube, resistor, and dielectric grease installed in the gun. The resistorservice kit includes dielectric grease.If you are performing an initial installation of the AN-8 Plus gun, refer toInstalling the Electrostatic Cable in this section.If you are installing a new cable or a new resistor service kit into apreviously installed AN-8 Plus gun, refer to Replacing the ResistorService Kit and Cable in the Repair section of this manual.When using highly conductive coating materials, install the optionalIsocoil in place of the standard fluid tube. The Isocoil increases thelength of the fluid tube and provides a greater resistance to theelectrostatic charge, which prevents it from traveling back to the handle.Use the following steps to install the optional miniature Isocoil on theAN-8 Plus gun.WARNING: Before installing the miniature Isocoil, relieve allpressure and turn off electrical power to the system. Failure toobserve this warning can result in serious personal injury ordeath.1. Relieve the system fluid pressure.2. See Figure 3-3. Remove the fluid tube (6) between the gunextension (1) and the gun handle (2).3. Connect the Isocoil swivel fitting (5) to the fluid inlet port (7) on thegun extension.4. Connect the Isocoil fluid tube (4) to the fluid port (3) on the gunhandle.7. Installing a NewExtension Resistor Kitand Cable8. Installing the OptionalMiniature Isocoil
