5.0. MOUNTING AND CONNECTION OF DIAPHRAGM PUMP A typical setup configuration is shown in figure 7. Further information and consultation on pump setup can be provided by your Ran Pump distributor. ALWAYS USE ORIGINAL RAN PUMP PARTS AND ACCESSORIES. FAILURE TO DO SO WILL INVALIDATE THE GUARANTEE Pump should fixed firmly to the ground or platform and should be fitted in a perpendicular position as shown in Figure 5. - Page 9 5.2. Tightening the bolts before first use After you unpack the pump, and before you use it for the first time, check and tighten external fasteners. Tighten the fluid cover screws first, then the manifold screws. (Refer to Figure 6 for torque figures).
- Page 10 Figure 8a - Typical installation scheme 5.5. Fluıd lıne 5.5.1. Fluid suction line 1- Use a conductive hose or pipe. 2- Screw fluid fitting into the pump inlet tightly. 3- If the inlet fluid pressure is more than 25% of the outlet working pressure, ball check valves will not close fast enough, result will be inefficient pump operation.
- Page 11 Caution. It is advisable to install a pressure relief system (bypass line)to relieve high levels of pressure that may occur if the pump is pressurised for a long period when not operating. On some uncontrolled systems the back pressure generated from a closed outlet hose can cause the pump to stop or even reverse operation.
- Page 12 5.6. Ventilating exhaust air You must vent the exhaust to a safe place, away from people, animals, food, and all sources of ignition when pumping flammable or hazardous fluids. Note that when there is a tear on the diaphragm, the media in the pump will be exhausted together with the air. To avoid this exhaust the gas away from the operation environment.
- Page 13 WARNING ! Diaphragm pumps are sold as pump unit only. Installing a control device (if needed) is responsibility of the operator. If the power supply of the pump (compressor) is stopped, the air inlet to the pump must be cut off immediately. Otherwise when compressor restarts, pump may start unexpectedly.

6.3. Stopping the pump Cut off the air when the pump is not working. WARNING ! PRESSURIZED EQUIPMENT HAZARD The equipment stays pressurized until pressure is manually relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray from the gun or splashing fluid, follow Pressure Relief Procedure whenever you ... - Page 15 7.2. Changing diaphragm Tools Required - Lithium-base grease (non-freezing silicone grease) - 13 mm wrench - 5 mm allen key - 10 mm wrench - Torque wrench WARNING! Transferred liquid enters the air chamber of the pump when the diaphragm ruptures. Liquid can damage the pilot valve o-rings and the air valve o-rings due to its chemical behaviour.
- Page 16 7.3 Air valve repair Tools Required - 4 mm allen key - 8 mm wrench - Philips-head screwdriver - Lithium-base grease (non-freezing silicone grease) NOTE: Hold the air valve vertical position if the core is sliding with its own weight in the valve body, valve z-rings need to be changed.

Page 17: Periodic Maintenance
8.0 PERIODIC MAINTENANCE 8.1 Cleaning and storage of the pump Do not let your fluid dry in the pump or in the hoses. It may harm the pump. Clean the pump regularly by pumping a suitable solvent for your fluid until the pump is cleaned. Make sure the fluids you are using are compatible with your diaphragm material. - Page 18 8.6 Troubleshooting PROBLEM CAUSE SOLUTION 1- Pump cycles at stall or fails to hold Worn check valve balls, seats or o-rings. Replace. pressure at stall. Disassamble and clean air valve. Use Air valve is stuck or dirty. ONLY filtered air. Check valve ball severely worn and Replace ball and seat.
