This symbol alerts you to the possibility of damage to or destruction of equipment if you do not follow the instructions. WARNING EQUIPMENT MISUSE HAZARD Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury. INSTRUCTIONS D This equipment is for professional use only.
WARNING PRESSURIZED EQUIPMENT HAZARD Spray from the gun, hose leaks, or ruptured components can splash fluid in the eyes or on the skin and cause serious injury. D Do not point the gun at anyone or at any part of the body. D Do not stop or deflect leaks with your hand, body, glove or rag. D Follow the Pressure Relief Procedure on page 11 whenever you: are instructed to relieve pressure; stop spraying; clean, check, or service the equipment; and install or clean the spray tip.
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 10. D If there is any static sparking or you feel an electric shock while using this equipment, stop spraying immediately. Do not use the equipment until you identify and correct the problem.
Installation General Information Prepare the Site NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures and the parts drawing. Ensure that the wall is strong enough to support the weight of the pump and accessories, fluid, hoses, and stress caused during pump operation. NOTE: Always use Genuine Graco Parts and Accessories, available from your Graco distributor.
Installation Supplied Components D The air line lubricator (11b) provides automatic lubrication of the air motor. Refer to Fig. 2 on page 9. WARNING A red-handled bleed-type master air valve (11h) and a fluid drain valve (D) are supplied. These components help reduce the risk of serious injury, including splashing of fluid in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump.
Installation Installing the Pump Module The pump module consists of the pump mounted on the pump bracket, the air controls, back pressure regulator, hoses, and plumbing. NOTE: Refer to Fig. 2 on page 9, and to the Dimension drawing on page 22 and the Mounting Hole Layout on page 23. Using the Quick Connectors To open a quick connector (11c), loosen the captive screw (S) and open the connector. Slide the desired component into the connector, close, and tighten the screw. See Fig. 1. S 1.

Installation 2. Air and fluid hoses: use only electrically conductive hoses. Grounding WARNING 3. Air compressor: follow manufacturer’s recommendations. 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. 4. Spray gun: ground through connection to a properly grounded fluid hose and pump. 1. Pump: use the ground wire and clamp (40, supplied). See Fig. 3. Loosen the grounding lug locknut (W) and washer (X).
Operation Pressure Relief Procedure WARNING PRESSURIZED EQUIPMENT HAZARD The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. To reduce the risk of an injury from accidental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you: D D D D are instructed to relieve the pressure, stop spraying, check or service any of the system equipment, or install or clean the spray nozzle. 1.
Operation Starting and Adjusting the Pump 1. Open all fluid shutoff valves (14, 15). Refer to Fig. 2 on page 9, and to Fig. 4. 2. Open the back pressure regulator (12). Turn the 3-way recirculation valve (19) to the circulation position. 3. Open the spray gun at the last gun station and keep it open while starting the pump.
Operation 1 Torque packing nut (H) to 34–40 NSm (25–30 ft-lb). Packing nut is partially hidden. 11h 15 11a 5 14 D H 12 1 19 42 21 ti17807a Fig.
Maintenance Preventive Maintenance Schedule The operating conditions of your particular system determine how often maintenance is required. Establish a preventive maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system. Flushing 3. Remove the filter element from the fluid filter (5). Reinstall the filter bowl. 4. Open the back pressure regulator (12). Set the 3-way recirculation valve (19) to the circulation position. 5.
