Grounding

WARNING

Fire, Explosion, and Electric Shock Hazard

When operating the electrostatic gun, any ungrounded objects in the spray area (peo- ple, containers, tools, etc.) can become electrically charged. Improper grounding can result in static sparking, which can cause a fire, explosion, or electric shock. Follow the grounding instructions below.

The following are minimum grounding requirements for a basic electrostatic system. Your system may include other equipment or objects which must be grounded.

Check your local electrical code for detailed grounding instructions. Your system must be connected to a true earth ground.

•Pump: ground the pump by connecting a ground wire and clamp as described in your separate pump instruction manual.

•All persons entering the spray area: shoes must have conductive soles, such as leather, or personal grounding straps must be worn. Do not wear shoes with non-conductive soles such as rubber or plastic. If gloves are necessary, wear the conductive gloves that are supplied with the gun. If non-Graco gloves are worn, cut off fingers or palm area of glove, to ensure your hand contacts the grounded gun han- dle.

•Object being sprayed: keep the workpiece hangers clean and grounded at all times. Resistance must not exceed 1 megohm.

•The floor of the spray area: must be electrically con- ductive and grounded. Do not cover the floor with cardboard or any non-conductive material which would interrupt grounding continuity.

•Electrostatic Air-Assisted Spray Gun: ground the gun by connecting the Graco Grounded Air Hose and connecting the air hose ground wire to a true

earth ground. See Check Electrical Grounding,
