Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.

WARNING

EQUIPMENT MISUSE HAZARD

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

• This equipment is for professional use only.

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

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

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

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

• Do not exceed the maximum working pressure of the lowest rated system component.

• Be sure that all spray/dispensing equipment and accessories are rated to withstand the maximum working pressure of the pump. Do not exceed the maximum working pressure of any component or accessory used in the system.

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

• Do not exceed the maximum temperature rating of any system component.

• 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.

• Always wear protective eyewear, gloves, clothing, and respirator as recommended by the fluid and solvent manufacturer.

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

FIRE, EXPLOSION, AND ELECTRIC SHOCK HAZARD

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

• Ground the equipment and the object being dispensed.

• Do not use this equipment with flammable liquids.

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

• If there is any static sparking or you feel an electric shock while using the equipment, stop dispens- ing immediately. Do not use the equipment until you have identified and corrected the problem.

• Be sure all electrical work is performed by a qualified electrician only.

• Have any checks, installation, or service to electrical equipment performed by a qualified electrician only.

• Be sure all electrical equipment is installed and operated in compliance with applicable codes

• Be sure power is disconnected when servicing and repairing equipment

• Before operating the equipment, extinguish all open flames or pilot lights in the dispense area

• Do not smoke in the dispensing area.

• Keep liquids away from the electrical components

• Disconnect electrical power at the main switch before servicing the equipment.

Warnings

WARNING

SKIN 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.

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

treatment.

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

• Follow the Pressure Relief Procedure in your separate equipment manuals whenever you are instructed to: relieve pressure; stop dispensing; clean, check, or service the equipment; or install or clean a nozzle.

• Tighten all the fluid connections before operating the equipment.

• Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately. Permanently coupled hoses cannot be repaired; replace the entire hose.

• Always wear eye protection and protective clothing when installing, operating, or servicing this dispensing equipment.

• Never wipe off build-up around the nozzle or inlet cap until pressure is fully relieved.

TOXIC FLUID OR FUMES HAZARD

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

• Provide fresh air ventilation to avoid the buildup of vapors from the fluid being dispensed.

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

• Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local, state and national guidelines.

• Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and solvent manufacturer.

• Avoid exposure to heated material fumes.

HOT SURFACE AND FLUID HAZARD

Heated fluid can cause severe burns and can cause equipment surfaces to become very hot.

• Wear protective gloves and clothing when operating this equipment in a heated system.

• Do not touch the metal heat sink when the surface is hot.

• Allow the equipment to cool thoroughly before servicing.

• Some heated systems are designed to dispense Polyurethane (PUR) heated materials. PUR Systems are supplied with ventilation hoods, and require proper ventilation and specifically designed system components.

Installation

Installing the Flow Meter

• Flow volume can only be measured at the location where the flow meter is installed.

Dust and Foreign Matter

Avoid having dust or foreign matter enter the flow meter by taking the following precautions:

• Thoroughly flush the fluid supply lines before installing the flow meter.

• When installing fittings, make sure that no sealing tape overlaps into the inside of the pipe.

• Install a 30 mesh fluid filter upstream of the flow meter.

• The flow meter was calibrated in oil. Flush the meter with a compatible solvent prior to use.

CAUTION

The use of PTFE tape or pipe seal on fluid fittings upstream of this meter should be avoided if possible. Contaminants from sealing material may damage the meter.

Electronic Sensor Device

• Do not use more than 200 ft. (61 m) of cable.

• Refer to FIG. 1 to locate and install the flow meter, connectors, and fluid shutoff valves. Install a check valve to prevent backflow. The arrows on the flow meter and check valve show the direction of fluid flow.

• The shutoff valves allow you to isolate the meter for service.

• Refer to the Technical Data and Dimensional Drawings for dimension, inlet/outlet size, temperature and other specifications.

Installation

Grounding

1. Always ground the fluid supply unit, using one of the following options:

a. Mount the meter to a grounded conductive sur-

face, or

b. Connect the conductive fluid hose to the meter

inlet and outlet.

c. Connect a ground wire to the meter’s M6

mounting holes.

2. Never use the flow meter with an electrostatic gun isolation stand.

NOTE: This drawing shows the pin connector used on

meters 246190 Series D, 246340 Series D, 246652 Series C, and newer. Older meters used a 5-pin connector.

Sensor Kit 246786 now includes a cable with a 4-pin connector, to replace the existing cable connection.
