Install the valve close to the pump fluid outlet. See FIG. 3. Typical Installation EF CB A 5. See the Technical Data on pages 34 and 37 for maximum suction lift (wet and dry). 1. Use flexible, grounded fluid hoses (L) where possible. 2. For best sealing results, use a standard Tri-Clamp® style sanitary gasket of a flexible material such as EPDM, Buna-N, fluoroelastomer, or silicon 3. Install a fluid drain valve (J) near the fluid outlet. See FIG. 3. 4. Install a shutoff valve (K) in the fluid outlet line.

To re-orientate the ports into any position: 1. Remove the clamps (130) holding the inlet and/or outlet tee to the elbows. 2. Rotate the manifold tee (339) and reattach. Install the clamps (130) and tighten handtight. FIG. 4 Orientation of Fluid Ports 130 339 TI5133e P Air Exhaust Ventilation 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. Diaphragm failure can 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. The air exhaust port is 3/4 npt(f). Do not restrict the air exhaust port. Excessive exhaust restriction can cause erratic pump operation. To provide a remote exhaust: 1. Remove the muffler (P) from the pump air exhaust port. See FIG. 5. 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. 3. Place a grounded container (U) at the end of the air exhaust line to catch fluid in case of a diaphragm rupture.

Shut off the air to the pump. 2. Open any available outbound fluid valve to relieve fluid pressure from the pump. 3. If fluid is still in the outbound fluid lines, isolate this fluid as follows: a. Close the outbound fluid valves. b. Slowly remove the fluid connections from the pump, and have a container ready to catch any fluid that runs out. Sanitizing the Pump Before First Use The pump was built and tested using a food grade lubricant. It is the user’s responsibility to properly sanitize the pump before first use. It is up to the user whether this will include disassembling and cleaning individual parts or simply flushing pump with a sanitizing solution. As necessary, follow the steps under Starting and Adjusting the Pump below, under Flushing on page 11, or under Disassembly in the Service section on pages 19, 21. Starting and Adjusting the Pump 1. Be sure the pump is properly grounded. Refer to Grounding on page 5. 2. Check connections to be sure they are tight. Tighten fluid inlet and outlet connections securely. 3. Place the suction tube (if used) in fluid to be pumped. If 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 inef ficient pump operation. 4. Place the end of fluid hose (L) into an appropriate container. 5. Close the fluid drain valve (J). 6. Back out the air regulator (C) knob, and open all bleed-type 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 increase air pressure with the air regulator (C) until the pump starts to cycle. Do not exceed the maximum operating air pressure as listed in the Technical Data section on pages 34 and 37. Allow the pump to cycle slowly until all air is pushed out of the lines and the pump is primed. Pump Shutdown At the end of the work shift, relieve pressure. 10 310622L Maintenance Maintenance Lubrication 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. CAUTION Do not over...
