Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury.

INSTRUCTIONS

D This equipment is for professional use only.

D Read all instruction manuals, tags, and labels before operating the equipment.

D Use the equipment only for its intended purpose. If you are not sure, call your Graco distributor.

D Do not alter or modify this equipment. Use only genuine Graco parts and accessories.

D Check equipment daily. Repair or replace worn or damaged parts immediately.

Caution Symbol

CAUTION

This symbol alerts you to the possibility of damage to or destruction of equipment if you do not follow the instructions.

D Do not exceed the maximum working pressure of the lowest rated system component. Refer to the

Technical Data on page 13 for the maximum working pressure of this equipment.

D Use fluids and solvents which are compatible with the equipment wetted parts. Refer to the Tech-

nical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.

D Route hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not expose

Graco hoses to temperatures above 180_F (82_C) or below –40_F (–40_C).

D Do not kink or over bend the hoses or use the hoses to pull equipment.

D Wear hearing protection when operating this equipment.

D Do not lift pressurized equipment.

D Comply with all applicable local, state, and national fire, electrical, and safety regulations.

WARNING

INJECTION HAZARD

Spray from the gun, 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 surgi-

cal treatment.

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

D Keep your hands away from the end of the drain valve when opening it.

D Lock the gun trigger safety when you stop spraying.

D Follow the Pressure Relief Procedure on page 5 if the spray tip clogs and before cleaning,

checking or servicing the equipment.

D Follow the Pressure Relief Procedure on page 5 before removing the regulator’s adjusting knob.

D Do not pressurize the system when the fluid regulator’s adjusting knob is removed.

D Tighten all fluid connections before operating the equipment.

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

Do not repair high pressure couplings; you must replace the entire hose.

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

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

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.

NOTE:

The Typical Installation drawings are only guides for selecting and installing a circulating or direct system. They are not actual system designs. Contact your Graco distributor for the particular type and size system best suited for your needs.

Installation

Multiple Circulating Spray Station

Install the fluid regulator(s) (G) in the spray gun fluid supply line (F) as shown in the Typical Installation drawing above or at right. Connect only one spray gun or dispensing valve to each fluid regulator.

Using pipe sealant on pipe threads, connect the fluid supply line (F) to the fluid regulator’s 1/4 npt(f) inlet. Connect the line from the gun (J) to the regulator’s 1/4 npt(f) outlet.

Make sure the direction of fluid flow agrees with the IN and OUT markings on the regulator body.

The regulator was tested in lightweight oil. Flush the entire system with a solvent compatible with the fluid being sprayed or dispensed, then test the system.

Single Direct Spray Station

Operation

Pressure Relief Procedure

WARNING

INJECTION HAZARD

The system pressure must be manually relieved to prevent the system from

starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you

D Are instructed to relieve the pressure

D Stop spraying

D Check or service any of the system equipment

D Install or clean the spray tip

1. Lock the gun trigger safety and any other equipment safety locks.

2. Turn off the power to the pump.

3. Unlock the gun trigger safety.

Operating the Regulator

CAUTION

D To avoid contaminants clogging or damaging the

regulator, you must clean and test the new system thoroughly before you admit fluid to the regulator.

D Always use the lowest possible air and fluid

pressures for your application. High pressures can cause premature spray tip and pump wear.

NOTES:

D The fluid pressure regulator controls pressure

downstream from its outlet.

D If using an accessory fluid pressure gauge (H), to

ensure a correct gauge reading, relieve the spray gun line pressure after reducing the regulator pressure.

1. Back the regulator adjusting screw (18) out (turn counterclockwise) until there is no spring pressure. Relieve the spray gun line pressure.

2. Turn the adjusting screw clockwise to increase the fluid pressure.

4. Close the bleed-type master air valve (required in your system).

5. Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve pressure.

6. Lock the gun trigger safety.

7. Slowly open the drain valve (required in your system), and have a container ready to catch the drainage.

8. Leave the drain valve open until you are ready to spray again.

If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the

tip guard retaining nut or hose end coupling, and relieve pressure gradually, then loosen completely, then clear the tip or hose.

3. Adjust the pump air pressure and fluid regulator for the desired spray pattern. Use the lowest possible air and fluid pressures for your application.

4. In a circulating system, also adjust the back pressure valve.

5. Record all the settings for future reference.
