Ground the System

WARNING

FIRE, EXPLOSION, AND

ELECTRIC SHOCK HAZARD

When operating the electrostatic device, any ungrounded objects in the spray area (such as people, containers, tools, etc.) can become electrically charged. Improper grounding can result in static sparking, which can cause a fire, explo- sion, or electric shock. Follow the grounding instructions below.

The following grounding instructions are minimum re- quirements for a basic electrostatic, waterborne 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.

1.Fluid Supply: Ground the fluid supply by connect- ing a ground wire and clamp between the fluid supply and a true earth ground. See your fluid supply instruction manual for grounding instruc- tions.

2.PRO 3500wb Electrostatic Air Spray Gun: Install the red-colored Graco electrically conduc- tive air hose between the gun and air supply line and connect the air hose ground wire to a true earth ground. Check the electrical grounding of the gun as instructed on page 15.

3.Graco Waterborne Fluid Hose: The conductive layer of the hose must be properly grounded by correct installation as instructed on pages 12 to 13.

4.Voltage Isolation System: Ground the system according to the manufacturer’s instructions.

5.All persons entering the spray area: Their shoes must have conductive soles, such as leather, or personal grounding straps must be worn. Rubber or plastic soles are not conductive. The operator must not wear gloves which insulate the hand from the spray gun. The gloves must be conductive or modified as shown on page 17.

6.Object being sprayed: Keep the workpiece hangers clean and grounded at all times. Contact points must be sharp points or knife edges.

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

8.All electrically conductive objects or devices in the spray area: They must be properly grounded.
