Installation
Connect the Exhaust Tube
Press the exhaust tube (provided) onto the barbed adapter on the bottom of the gun handle. Secure the tube with the clamp provided. Refer to page 34.
Connect the Fluid Line (Refer to Fig. 1, page 6)
1.Before connecting the fluid line (N), blow it out with air and flush it with solvent. Use solvent which is compatible with the fluid to be sprayed.
2.Install a fluid regulator (M) on the fluid line to control fluid pressure to the gun.
3.Install a fluid filter (K) and drain valve (U) at the pump outlet.
WARNING
PRESSURIZED EQUIPMENT HAZARD
The fluid drain valve (U) is required in your system to assist in relieving fluid pressure in the displace- ment pump, hose and gun; triggering the gun to relieve pressure may not be sufficient. Install a drain valve close to the pump’s fluid outlet. The drain valve reduces the risk of serious injury, including splashing in the eyes or on the skin.
4.Connect the fluid line to the
5.Before running any paint through the spray gun, flush it out with a compatible solvent.
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 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.
1.Pump: ground the pump by connecting a ground wire and clamp as described in your separate pump instruction manual.
2.Air compressors and hydraulic power supplies: ground the equipment according to the manufac- turer’s recommendations.
3.Electrostatic Air Spray Gun: ground the gun by connecting the Graco Electrically Conductive Air Hose and connecting the air hose ground wire to a true earth ground. Check the electrical grounding of the gun as instructed on page 9.
4.All air and fluid lines must be properly grounded. Use only grounded hoses with a maximum of 500 feet (150 m) combined hose length to ensure grounding continuity.
5.All electric cables must be properly grounded.
6.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 that insulate the hand from the spray gun. The gloves must be conductive or modified as shown in Fig. 3, page 11.
7.Object being sprayed: keep the workpiece hangers clean and grounded at all times. Contact points must be sharp points or like knife edges.
8.The floor of the spray area: must be electrically conductive and grounded. Do not cover the floor with cardboard or any
9.Flammable liquids in the spray area: must be kept in approved, grounded containers. Do not store more than the quantity needed for one shift.
10.All electrically conductive objects or devices in the spray area: including fluid containers and wash cans, must be properly grounded.
