Installation

Grounding

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: loosen the grounding lug locknut (W) and washer (X). Insert one end of a 12 ga (1.5 mm2) minimum ground wire (Y) into the slot in lug (Z) and tighten the locknut securely. See Fig. 1. Connect the other end of the wire to a true earth ground. Order Part No. 237569, Ground Wire and Clamp.

2. Air and fluid hoses: use only electrically conductive hoses with a maximum of 500 ft (150 m) combined hose length to ensure grounding continuity.

3. Air compressor: follow manufacturer’s recommendations.

5. Object being sprayed: according to your local code.

6. Fluid supply container: according to your local code.

7. All solvent pails used when flushing, according to 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.

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

4. Spray gun: grounding is obtained through connection to a properly grounded fluid hose and pump.

Installation

NOTE: Reference numbers and letters in parentheses

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

Contact your Graco distributor for available accessories. If you supply your own accessories, be sure they are adequately sized and pressure–rated to meet the system’s requirements.

The Typical Installation shown on page 7 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.

System Accessories

Refer to the Typical Installation drawing on page 7.

WARNING

Two accessories are required in your system: a bleed-type master air valve (D) and a fluid drain valve (J). These accessories help reduce the risk of serious injury including splashing in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump.

The bleed-type master air valve relieves air trapped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cycle unexpectedly. Locate the valve close to the pump.

The fluid drain valve assists in relieving pressure in the displacement pump, hose, and gun. Triggering the gun to relieve pressure may not be sufficient.

Mounting Accessories

Mount the pump (A) to suit the type of installation planned. The pump dimensions and mounting hole layout are shown on page 22.

Air and Fluid Hoses

Be sure all air and fluid hoses are properly sized and pressure–rated for your system. Use only grounded air and fluid hoses. Fluid hoses must have spring guards on both ends.

Connect a grounded fluid hose (L) to the pump’s 3/8 npt(f) fluid outlet. Use of a short whip hose between the main fluid hose (L) and the gun (M) allows freer gun movement.

Connect a fluid suction hose (N) to the pump’s 3/4 npt(m) fluid intake.

Use a grounded 1/2 in. I.D. (minimum) air hose (H) to supply air to the pump.

Air Line Accessories

Install the following accessories in the order shown in the Typical Installation, using adapters as necessary:

D A pump runaway valve (B) senses when the

pump is running too fast and automatically shuts off the air to the motor. A pump which runs too fast can be seriously damaged. Install closest to the pump air inlet.

D An air line lubricator (C) provides automatic air

motor lubrication.

D A bleed–type master air valve (D) is required in

your system to relieve air trapped between it and the air motor when the valve is closed (see the WARNING at left). Be sure the bleed valve is easily accessible from the pump, and is located down- stream from the air regulator.

D An air regulator (E) controls pump speed and

outlet pressure by adjusting the air pressure to the pump. Locate the regulator close to the pump, but upstream from the bleed–type master air valve.

D An air line filter (F) removes harmful dirt and

moisture from the compressed air supply.

D A second bleed–type air valve (G) isolates the air

line accessories for servicing. Locate upstream from all other air line accessories.

Fluid Line Accessories

Install the following accessories in the positions shown in the Typical Installation, using adapters as necessary:

D A fluid drain valve (J) is required in your system

to relieve fluid pressure in the hose and gun (see the WARNING at left). Install the drain valve pointing down, but so the handle points up when opened.

D A fluid filter (K) filters harmful particles from the

fluid.

D A spray gun (M) dispenses the fluid. The gun

shown in the Typical Installation is an airless spray gun.
