Page 2: Important Safety Requirements
1.0. IMPORTANT SAFETY REQUIREMENTS a- This equipment is for professional use only. Observe all warnings. Read and understand all instruction manuals, warning labels, and tags before you operate the equipment. b- CAUTION: This manual contains important instructions and safety cautions on diaphragm pumps. - Page 3 WARNING ! Always wear appropriate clothing and equipment, such as eye protection and breathing apparatus, to protect yourself. WARNING ! Improper handling, splashing in the eyes, ingestion, or bodily contamination of hazardous fluids or inhaling toxic vapors can cause extremely serious injury or death. Observe all the following precautions when handling known or potentially hazardous fluids.

Page 8: Mounting And Connecting Of Diaphragm Pump
5.0. MOUNTING AND CONNECTION OF DIAPHRAGM PUMP A typical setup configuration is shown in figure 8a. 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 be 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 7 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 Ground the pump as shown below 5.6.1 For the pump: Use a conductor (for grounding) with a cross-section of at least 1.5 mm . Connect the conductor to the pump’s leg as shown on Fig. 7, and the other end to the grounding line.
- Page 13 IMPORTANT NOTE : If the diaphragm pump is submerged in water it is important that the fluid will not enter the air exhaust system. To ensure this please use the special exhaust cover with suitable attached hose with hose exit not submerged in fluid.
- Page 14 6.2 Starting and adjusting the pump 1- Check pump grounding before use. 2- Check fittings to be sure they are tight. Use a compatible liquid thread sealant (teflon, etc.) on male threads. Tighten fluid inlet and outlet fittings securely. 3- Submerge the suction hose in the fluid. Note: 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.

Ball check valve repair Tools required - Torque wrench - 17 mm wrench - 15 mm wrench 7.1.1 Dismantling... - Page 16 7.2. Changing diaphragm Tools Required - Lithium-base grease (non-freezing silicone grease) - 17 mm wrench - 15 mm wrench - 32 mm wrench - torque wrench - Philips-head screwdriver WARNING! Transferred liquid enters air chamber of pump when the diaphragm ruptures.
- Page 17 7.3 Air valve repair Tools Required - Torque wrench - 5 mm allen key - Z-ring pick - 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 18: Periodic Maintenance
Figure 13b - Pilot valve repair. 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 19 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. Air valve is stuck or dirty. Use ONLY filtered air. Check valve ball severely worn and Replace ball and seat.
