Warnings 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 symbol refers to procedure-specific risk. When these symbols appear in the body of this manual, refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.
Warnings 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 Technical Data 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.
Warnings WARNING TOXIC FLUID OR FUMES HAZARD Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed. • Read MSDS’s to know the specific hazards of the fluids you are using. • Route exhaust away from work area. If diaphragm ruptures, fluid may be exhausted with air. • Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
Installation Installation General Information • The Typical Installations shown in FIG. 3 through FIG. 5 are only guides for selecting and installing system components. Contact your Graco distributor for assistance in planning a system to suit your needs. • Installation and use must be in accordance with the Flammable and Combustible Liquids Code (NFPA 30) and Automotive and Marine Service Station Code (NFPA 30a) and must comply with all local, state, and federal codes. • 2.
Installation Air Line Install the air line accessories as shown in FIG. 3 through FIG. 5. Mount these accessories on the wall or on a bracket. Be sure the air line supplying the accessories is grounded. GS R ti12214a FIG. 1. Ground screw and wire Air and fluid hoses: Use only grounded hoses with a maximum of 500 ft (150 m) combined hose length to ensure grounding continuity. Air compressor: Follow manufacturer’s recommendations. Fluid supply container: Follow local code.
Installation Air Exhaust Ventilation Be sure to read and follow the TOXIC FLUID OR FUMES HAZARD warnings, page 7, and FIRE AND EXPLOSION HAZARD warnings, page 5, before operating this pump. You must vent the exhaust away from people, animals, food handling areas, and all sources of ignition when pumping flammable or hazardous fluids. Vent in accordance with local codes, or in the absence of local codes, an industry or nationally recognized code having jurisdiction over the specific installation.

Installation Fluid Pressure Relief Valve Fuel Dispense Systems (Model 647648) Fuel dispense model 647648 requires a pressure relief valve (S), Graco part 24B910, which is supplied with the pump, to prevent fluid pressure from exceeding 50 psi (350 kPa, 3.5 bar). See FIG. 5, page 13. Recommended air operating pressure is 40 psi (280 kPa, 2.8 bar) or less. As the air inlet pressure approaches 50 psi (350 kPa, 3.5 bar), the relief valve will open and vent fluid.
Operation Operation Pressure Relief Procedure Waste Oil Receiver Evacuation Systems or General Fluid Transfer Applications See FIG. 3. Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing. 1. Shut off the air supply to the pump. 2. Open the dispensing valve (if used). 1. Close the pump air regulator (C) and the bleed-type master air valves (B, E). 2. Connect the pump suction hose (G) to the pump fluid inlet.
Operation Gear Oil Evacuation Systems See FIG. 4. 1. Close the pump air regulator (C) and the bleed-type master air valves (B, E). 2. Attach an appropriate wand to the suction hose. Place the wand in the differential or fluid to be pumped. 3. Place the end of the fluid hose into an appropriate container. 4. Close the fluid drain valve (H). Open the fluid shutoff valve (J). 5. Connect the air supply line to the pump air inlet (D). 6. Open the bleed-type master air valves (B, E). 7.
Maintenance Maintenance Flushing and Storage Maintenance Schedule Establish a preventive maintenance schedule, based on the pump’s service history. Scheduled maintenance is especially important to prevent spills or leakage due to diaphragm failure. Lubrication The pump is lubricated at the factory. It is designed to require no further lubrication for the life of the pump. There is no need to add an in-line lubricator under normal operating conditions.
Maintenance Torque Instructions NOTE: Fluid cover and manifold fasteners have a thread-locking adhesive patch applied to the threads. If this patch is excessively worn, the fasteners may loosen during operation. Replace screws with new ones or apply medium-strength (blue) Loctite or equivalent to the threads. If fluid cover or manifold fasteners have been loosened, it is important to torque them using the following procedure to improve sealing.
