WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury.

D Ground the equipment and the object being sprayed. Refer to Grounding on page 5.

D If there is any static sparking or you feel an electric shock while using this equipment, stop spray-

ing immediately. Do not use the equipment until you identify and correct the problem.

D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid

being sprayed.

D Eliminate all ignition sources such as pilot lights, cigarettes and plastic drop cloths (static arc

hazard). Do not plug or unplug power cords or turn lights on or off in the spray area.

D Keep the spray area free of debris, including solvent, rags, and gasoline.

D Electrically disconnect all equipment in the spray area.

D Do not operate a gasoline engine in the spray area.

Installation

General Information

NOTE: Reference numbers and letters in parentheses

in the text refer to the callouts in the figures and the parts drawing.

NOTE: Always use Genuine Graco Parts and Accessories, available from your Graco distributor. If you supply your own accessories, be sure they are adequately sized and pressure rated for your system.

Fig. 2 is only a guide for selecting and installing system components and accessories. Contact your Graco distributor for assistance in designing a system to suit your particular needs.

Prepare the Operator

All persons who operate the equipment must be trained in the safe, efficient operation of all system components as well as the proper handling of all fluids. All operators must thoroughly read all instruction manuals, tags, and labels before operating the equipment.

Grounding

0864

Fig. 1

2. Air and fluid hoses: use only electrically conductive hoses.

3. Air compressor: follow manufacturer’s recommendations.

4. Spray gun: ground through connection to a properly grounded fluid hose and pump.

5. Fluid supply container: follow your local code.

6. Object being sprayed: follow your local code.

7. Solvent pails used when flushing: follow your local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, ground the system as explained below. Also read the section FIRE AND EXPLOSION HAZARD on page 4.

1. Pump: order Part No. 237569 Ground Wire and Clamp. See Fig. 1. Loosen the grounding lug locknut (W) and washer (X). Insert one end of the ground wire (Y) into the slot in lug (Z) and tighten the locknut securely. Connect the other end of the wire to a true earth ground.

8. To maintain grounding continuity when flushing or relieving pressure, hold a metal part of the spray gun firmly to the side of a grounded metal pail, then trigger the gun.

Mounting the Pump

Mount the pump to suit the type of installation planned. The pump dimensions and mounting hole layout are shown on page 16.

If the pump is immersed, be sure the pump intake is 1/2 in. (13 mm) off the bottom of the fluid container.

If the pump is mounted on the wall or on a stand, connect a suction line to the pump’s 1–1/2” npt(f) fluid inlet and place the other end of the line in the fluid container.
