Gun Setup 13. Fully open the fan air adjustment valve (F) counterclockwise. 14. Fully open the uid adjustment valve (H) counterclockwise. 15. Fully open the atomizing air restrictor valve (G) clockwise. 16. Turn ON (I) the ES On-Off switch (J). 17.
Gun Setup 19. Shut off the air to the gun. Turn OFF (O) the ES On-Off switch (J). 20. Start the pump. Adjust the uid regulator until the stream from the gun travels 8-12 in. (200-300 mm) before falling off. Typically, if uid pressure is below 5 psi (.
Gun Setup Grounding Grounding Grounding When operating the electrostatic gun, any ungrounded objects in the spray area (people, containers, tools, etc.) can become electrically charged. Improper grounding can result in static sparking, which can cause a re, explosion, or electric shock.
Gun Setup • The oor of the spray area: must be electrically conductive and grounded. Do not cover the oor with cardboard or any non-conductive material which would interrupt grounding continuity. • Flammable liquids in the spray area: must be kept in approved, grounded containers.
