WARNING

INJECTION HAZARD

Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can also cause serious injury.

D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medi-

cal attention.

D Do not point the gun at anyone or at any part of the body.

D Do not put your hand or fingers over the spray tip.

D Do not stop or deflect leaks with your hand, body, glove or rag.

D Do not “blow back” fluid; this is not an air spray system.

D Always have the tip guard and the trigger guard on the gun when spraying.

D Check the gun diffuser operation weekly. Refer to the gun manual.

D Be sure the gun trigger safety operates before spraying.

D Lock the gun trigger safety when you stop spraying.

D Follow the Pressure Relief Procedure on page 10 whenever you: are instructed to relieve pres-

sure; stop spraying; clean, check, or service the equipment; and install or clean the spray tip.

D Tighten all fluid connections before operating the equipment.

D Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.

Permanently coupled hoses cannot be repaired; replace the entire hose.

D Use only Graco approved hoses. Do not remove any spring guard that is used to help protect the

hose from rupture caused by kinks or bends near the couplings.

MOVING PARTS HAZARD

Moving parts, such as the air motor piston, can pinch or amputate your fingers.

D Keep clear of all moving parts when starting or operating the pump.

D Before servicing the equipment, follow the Pressure Relief Procedure on page 10 to prevent the

equipment from starting unexpectedly.

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 7.

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

D Electrically disconnect all equipment in the spray area.

D Extinguish all open flames or pilot lights in the spray area.

D Do not smoke in the spray area.

D Do not turn on or off any light switch in the spray area while operating or if fumes are present.

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

TOXIC FLUID HAZARD

Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed.

D Know the specific hazards of the fluid you are using.

D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,

state and national guidelines.

D Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and

solvent manufacturer.

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. Refer to Product Data Sheet, Form No. 305724. If you supply your own accessories, be sure they are adequately sized and pressure rated for your system.

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 5.

1. Pump: use a ground wire and clamp. See Fig. 1. Loosen the grounding lug locknut (W) and washer (X). Insert one end of a 1.5 mm@ (12 ga) minimum 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. Order Part No. 237569 Ground Wire and Clamp.

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.

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.

System Accessories

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.

Air and Fluid Hoses

Be sure all air hoses (H) and fluid hoses (N and P) are properly sized and pressure-rated for your system. Use only electrically conductive hoses. Fluid hoses must have spring guards on both ends. Use a whip hose (P) and a swivel (R) between the main fluid hose (N) and the gun (S) to allow freer gun movement.

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

Mounting Accessories

Mount the pump (A) to suit the type of installation planned. Fig. 2 illustrates a wall mount system. Pump dimensions and the mounting hole layout are shown on page 27.

If you are using a floor stand, refer to its separate manual for installation and operation instructions.

Installation

System Accessories (continued)

WARNING

A bleed-type master air valve (E) and a fluid drain valve (M) are required in your system. These accessories help reduce the risk of serious injury, including fluid injection and splashing of fluid 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. Order Part No. 107141.

The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and gun. Triggering the gun to relieve pressure may not be sufficient. Order Part No. 235992.

Air Line Accessories

Install the following accessories in the locations shown in Fig. 2, using adapters as necessary:

D An air line lubricator (D) provides automatic air

motor lubrication.

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

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

D A pump runaway valve (C) 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.

D An air manifold (G) has a 3/4 npsm(f) swivel air

inlet. It mounts to the pump support bracket, and provides ports for connecting lines to air-powered accessories.

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

moisture from the compressed air supply. Also, install a drain valve (W) at the bottom of each air line drop, to drain off moisture.

D A second bleed-type air valve (K) isolates the air

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

Fluid Line Accessories

Install the following accessories in the locations shown in Fig. 2, using adapters as necessary:

D A fluid filter (L) with a 60 mesh (250 micron)

stainless steel element, to filter particles from the fluid as it leaves the pump.

D A fluid drain valve (M), which is required in your

system, helps relieve fluid pressure in the hose and gun (see the WARNING at left).

D A gun (S) dispenses the fluid. The gun shown in

Fig. 2 is an airless spray gun for light to medium viscosity fluids.

D A gun swivel (R) allows freer gun movement.

D A suction kit (T) allows the pump to draw fluid

from a supply container.

D An air regulator (F) controls pump speed and out-

let 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.

CAUTION

To prevent intake valve damage, always apply PTFE

tape to the female threads of the intake valve before connecting a suction hose or fitting to the intake.
