Air compressor: Follow the manufacturer’s recommendations. All solvent pails used when flushing: Follow the local code. Use only metal pails, which are conductive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which interrupts the grounding continuity. Fluid supply container: Follow the local code. 308441 5 Installation c. Mountings CAUTION The pump exhaust air may contain contaminants. Ventilate to a remote area if the contaminants could affect your fluid supply. See Air Exhaust Ventilation on page 9. 1. Be sure the mounting surface can support the weight of the pump, hoses, and accessories, as well as the stress caused during operation. 2. For all mountings, be sure the pump is bolted directly to the mounting surface. 3. For ease of operation and service, mount the pump so the air valve cover (2), air inlet, and fluid inlet and outlet ports are easily accessible. 4. Rubber Foot Mounting Kit 236452 is available to reduce noise and vibration during operation. Air Line WARNING A bleed-type master air valve (B) is required in your system to relieve air trapped between this valve and the pump. Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury, including splashing in the eyes or on the skin, injury from moving parts, or contamination from hazardous fluids. See Fig. 2. 1. Install the air line accessories as shown in Fig. 2. Mount these accessories on the wall or on a bracket. Be sure the air line supplying the accessories is grounded. a. Install an air regulator (C) and gauge to control the fluid pressure. The fluid outlet pressure will be the same as the setting of the air regulator. b. Locate one bleed-type master air valve (B) close to the pump and use it to relieve trapped air. See the WARNING above. Locate the other master air valve (E) upstream from all air line accessories and use it to isolate them during cleaning and repair. 6 308441 The air line filter (F) removes harmful dirt and moisture from the compressed air supply. 2. Install a grounded, flexible air hose (A) between the accessories and the 1/2 npt(f) pump air inlet (N). See Fig. 3. Use a minimum 1/2 in. (13 mm) ID air hose. Screw an air line quick disconnect coupler (D) onto the end of the air hose (A), and screw the mating fitting into the pump air inlet snugly. Do not connect the coupler (D) to the fitting until you are ready to operate the pump. Installation of Remote Pilot Air Lines 1. Refer to Parts Drawings. Connect air line to pump as in preceding steps. 2. Connect 1/4 in. O.D. tubing to push type connectors (14) on air motor of pump. NOTE: by replacing the push type connectors, other sizes or types of fittings may be used. The new fittings will require 1/8 in. npt threads. 3. Connect remaining ends of tubes to external air signal, such as Graco’s Cycleflo (P/N 195264) or Cycleflo II (P/N195265) controllers. NOTE: the air pressure at the connectors must be at least 30% of the air pressure to the air motor for the pump to operate. Fluid Suction Line 1. Use grounded fluid hoses (G). The pump fluid inlet (R) is 1–1/2 in. npt(f). Screw the fluid fitting into the pump inlet securely. 2. If the fluid inlet pressure to the pump is more than 25% of the outlet working pressure, the ball check valves will not close fast enough, resulting in inefficient pump operation. 3. At inlet fluid pressures greater than 15 psi (0.1 MPa, 1 bar), diaphragm life will be shortened. 4. See the Technical Data on page 32 for maximum suction lift (wet and dry). Installation 1. Use grounded fluid hoses (L). The pump fluid outlet (S) is 1–1/2 in. npt(f). Screw the fluid fitting into the pump outlet securely. Fluid Outlet Line WARNING A fluid drain valve (J) is required to relieve pressure in the hose if it is plugged. The drain valve reduces the risk of serious injury, including splashing in the eyes or on the skin, or contamination from hazardous fluids when relieving pressure. Install the valve close to the pump fluid outlet. See Fig. 2. 2. Install a fluid drain valve (J) near the fluid outlet. See the WARNING above. 3. Install a shutoff valve (K) in the fluid outlet line.

Do not restrict the air exhaust port. Excessive exhaust restriction can cause erratic pump operation. Air Exhaust Ventilation WARNING If the muffler (P) is installed directly to the air exhaust port, apply PTFE thread tape or anti–seize thread lubricant to the muffler threads before assembly. FIRE AND EXPLOSION HAZARD Be sure to read and follow the warnings and precautions regarding TOXIC FLUID HAZARD, and FIRE OR EXPLOSION HAZARD on page 4, before operating this pump. To provide a remote exhaust: 1. Remove the muffler (P) from the pump air exhaust port. Be sure the system is properly ventilated for your type of installation. You must vent the exhaust to a safe place, away from people, animals, food handling areas, and all sources of ignition when pumping flammable or hazardous fluids. 2. Install a grounded air exhaust hose (T) and connect the muffler (P) to the other end of the hose. The minimum size for the air exhaust hose is 3/4 in. (19 mm) ID. If a hose longer than 15 ft (4.57 m) is required, use a larger diameter hose. Avoid sharp bends or kinks in the hose. See Fig. 5. Diaphragm failure will cause the fluid being pumped to exhaust with the air. Place an appropriate container at the end of the air exhaust line to catch the fluid. See Fig. 5. 3. Place a container (U) at the end of the air exhaust line to catch fluid in case a diaphragm ruptures.

To reduce the risk of serious injury from pressurized fluid, accidental spray from the gun or splashing fluid, follow this procedure whenever you: Are instructed to relieve pressure, Stop pumping, Check, clean or service any system equipment, Install or clean fluid nozzles. 1. Shut off the air to the pump. 2. Open the dispensing valve, if used. 3. Open the fluid drain valve to relieve all fluid pressure, having a container ready to catch the drainage. Flush the Pump Before First Use The pump was tested in water. If water could contaminate the fluid you are pumping, flush the pump thoroughly with a compatible solvent. Follow the steps under Starting and Adjusting the Pump. Starting and Adjusting the Pump WARNING TOXIC FLUID HAZARD To reduce the risk of serious injury, splashing in the eyes or on the skin, and toxic fluid spills, never move or lift a pump under pressure. If dropped, the fluid section may rupture. Always follow the Pressure Relief Procedure above before lifting the pump. 1. Be sure the pump is properly grounded. Refer to Grounding on page 5. 2. Check all fittings to be sure they are tight. Be sure to use a compatible liquid thread sealant on all male threads. Tighten the fluid inlet and outlet fittings securely. 3. Place the suction tube (if used) in the fluid to be pumped. 10 308441 NOTE: If the fluid inlet pressure to the pump is more than 25% of the outlet working pressure, the ball check valves will not close fast enough, resulting in inefficient pump operation. 4. Place the end of the fluid hose (L) into an appropriate container. 5. Close the fluid drain valve (J). See Fig. 2. 6. Close the pump air regulator (C). Open all bleedtype master air valves (B, E). 7. If the fluid hose has a dispensing device, hold it open while continuing with the following step. 8. Slowly open the air regulator (C) until the pump starts to cycle. Allow the pump to cycle slowly until all air is pushed out of the lines and the pump is primed. If you are flushing, run the pump long enough to thoroughly clean the pump and hoses. Close the air regulator. Remove the suction tube from the solvent and place it in the fluid to be pumped. Operation of Remote Piloted Pumps 1. Follow preceding steps 1 through 7 of Starting and Adjusting Pump. 2. Open air regulator (C). WARNING The pump may cycle once before the external signal is applied. Injury is possible. If pump cycles, wait until end before proceeding. 3. Pump will operate when air pressure is alternately applied and relieved to push type connectors (14). NOTE: Leaving air pressure applied to the air motor for extended periods when the pump is not running may shorten the diaphragm life. Using a 3–way solenoid valve to automatically relieve the pressure on the air motor when the metering cycle is complete prevents this from occurring. Pump Shutdown WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure at left. At the end of the work shift, relieve the pressure. Maintenance Lubrication Flushing and Storage The air valve is designed to operate unlubricated, however if lubrication is desired, every 500 hours of operation (or monthly) remove the hose from the pump air inlet and add two drops of machine oil to the air inlet. WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 10. CAUTION Do not over-lubricate the pump. Oil is exhausted through the muffler, which could contaminate your fluid supply or other equipment. Excessive lubrication can also cause the pump to malfunction. Tightening Threaded Connections Flush the pump often enough to prevent the fluid you are pumping from drying or freezing in the pump and damaging it. Use a compatible solvent. Always flush the pump and relieve the pressure before storing it for any length of time. Before each use, check all hoses for wear or damage, and replace as necessary. Check to be sure all threaded connections are tight and leak–free. Check fasteners. Tighten or retorque as necessary. Although pump use varies, a general guideline is to retorque fasteners every two months. See Torque Sequence, page 28. 308441 11 Troubleshooting WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 10.
