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,

Flammable liquids in the spray area: must be kept in

approved, grounded containers. Do not use plastic

 

containers. Do not store more than the quantity

 

needed for one shift.

Air compressors: ground the equipment according to the manufacturer's recommendations.

 

All electrically conductive objects or devices in the

All air and fluid lines must be properly grounded.

spray area: including fluid containers and wash

cans, must be properly grounded.

Use only grounded hoses with a maximum of 100

 

feet (30.5 m) combined hose length to ensure

 

grounding continuity.
