WARNING

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not operate the unit when fatigued or under the influence of drugs or alcohol.

• Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technic al Dat a in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information about your material, request MSDS from distributor or retailer.

• Do not leave the work area while equipment is energized or under pressure.

• Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only.

• Do not alter or modify equipment. Alterations or modifications may void agency approvals and create safety hazards.

• Make sure all equipment is rated and approved for the environment in which you are using it.

• Use equipment only for its intended purpose. Call your distributor for information.

• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

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

• Keep children and animals away from work area.

• Comply with all applicable safety regulations.

PRESSURIZED EQUIPMENT HAZARD

Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury.

• Follow the Pressure Relief Procedure when you stop spraying/dispensing and before cleaning, checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

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

Warnings

WARNING

FIRE AND EXPLOSION HAZARD

When flammable fluids are present in the work area, such as gasoline and windshield wiper fluid, be aware that flammable fumes can ignite or explode. To help prevent fire and explosion:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources, such as cigarettes and portable electric lamps.

• Keep work area free of debris, including rags and spilled or open containers of solvent and gasoline.

• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.

• Ground all equipment in the work area.

• Use only grounded hoses.

• Stop operation immediately if static sparking occurs or you feel a shock. Do not use equipment until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

SKIN INJECTION HAZARD

High-pressure fluid from dispensing device, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical

treatment.

• Do not point dispensing device at anyone or at any part of the body.

• Do not put your hand over the fluid outlet.

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

• Follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses and couplings daily. Replace worn or damaged parts immediately.

Common Terms

The installation shown in FIG. 1 is only a guide. The components shown are typical; however, it is not a complete system design. Contact your Graco distributor for assistance in designing a system to suit your particular needs.

NOTICE

This dispense valve is not designed for in-line installation. Do not install with a shut-off valve on the outlet side of the meter. Such installation could result in damage to the meter housing cover.

Installation

Grounding

The equipment must be grounded to reduce the risk of static sparking and electric shock. Electric or static sparking can cause fumes to ignite or explode. Improper grounding can cause electric shock. Grounding provides an escape wire for the electric current.

Refer to the user manuals for the pump and other system components, and ground the following:

• Pump: follow the manufacturer’s recommendations.

• Fluid hoses: use only grounded hoses.

• Air compressor: follow the manufacturer’s recommendations.

• Fluid supply container: follow the local codes.

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

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

NOTE: If you suspect the dispensing valve, extension or grease fitting coupler is clogged, or that pressure has not been fully relieved after following all the previous steps, using a rag, VERY SLOWLY loosen the coupler or

hose end coupling and allow pressure to be relieved gradually, then loosen the part completely and clear the clog.

Installation Procedure

NOTICE

If this is a new installation, or if the grease in the lines is contaminated, flush the lines before you install the metered valve. Contaminated lines can cause the valve to leak or malfunction.

If this is an existing installation, go to step 6.

1. Close the fluid shut-off valve (A) at each dispense stations. (Fig 1, page 4)

2. Make sure the main fluid outlet valve at the pump is closed, the air pressure to the pump motor is adjusted, and the air valve is open. Slowly open the main fluid valve.

3. Place the hose end (with no dispense valve connected) into a container for waste grease. Secure the hose in the container so it will not come out during flushing.

NOTE: If you have multiple dispense positions, first flush the dispense position farthest from the pump, and work

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.

1. Turn off the power supply to the pump.

2. Trigger the dispense valve into a waste container to relieve pressure.

3. Open any bleed-type master air valves and fluid drain valves in the system.

4. Leave the drain valve open until you are ready to pressurize the system.

your way toward the pump.

4. Slowly open the shut-off valve (A) at the dispense station. Flush out a sufficient amount of grease to ensure that the entire system is clean, and close the valve. (F

5. Repeat step 4 at all other dispense stations.

6. Relieve the pressure. See Pressure Relief Procedure.

Always ensure that the thread of the hose (or swivel) is compatible with the thread of the Accu-Shot dispense.
