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.

Pumps are packed in carton boxes. Figure 4 – Pump package. Pump package must be at least 200 grams and produced from the kraft carton. It must be fully covered with packaging separators.
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.

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).

Figure 8a - Typical installation scheme 5.5. Fluıd line 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.

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.

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 line with suitable attached hose with hose exit not submerged in fluid.

6.0. PUMP OPERATION INSTRUCTIONS IMPORTANT NOTE The pump has a variable temperature resistance to the transferred fluid. The temperature resistance of the diaphragm, ball, and ball seat defines the temperature resistance of the pump. 6.1. Flush the pump before use Pump is tested with water.
6.4. Pressure relief procedure 1- Shut off the air valve. To relieve the air between the air valve and the pump, use the Air Pressure Discharge Valve. 2- Shut off the Fluid Valve. Place a container under the Fluid Pressure Discharge Valve and open the valve.

7.2. Changing diaphragm Tools Required - Lithium-base grease (non-freezing silicone grease) - 13 mm wrench - 32 mm wrench - Torque wrench WARNING! Transferred liquid enters the air chamber of pump when the diaphragm ruptures. Liquid can damage the pilot valve o-rings and the air valve o-rings due to its chemical behaviour.

7.3 Air valve repair Tools Required - 5 mm allen key - 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.
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.
8.6 Troubleshooting PROBLEM CAUSE SOLUTION 1- Pump cycles at Worn check valve balls, seats or o- stall or fails to hold Replace. rings. 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.
