26 Working principle of the unit Working principle of the unit The following contains a description of how the unit functions, using the example of the Standard version unit. The LowViscosity Unit LVU is intended for offline filtration. The LVU removes solid particle contamination and free water from diesel fuel. Diesel fuel is often subject to long storage periods, especially in tanks which may be used infrequently. As a result, solid particles and water are often deposited on the bottom of the tank and can then damage pumps and sensitive components when switching on the motor. In addition, over an extended period of time free water in a tank provides a breeding ground for diesel fuel pests (microorganisms such as bacteria, algae, fungus, etc.). Both can quickly lead to blockage of the machine filter and to damage to diesel injection system components. The consequence: impermissibly high levels of pollutants from the combustion engine. This leads to high costs for down time, spare parts, maintenance and repairs. The use of the LowViscosity Unit LVU minimizes contamination to a system and prevents expensive system down time. It also helps to avoid the necessity of early and expensive disposal of diesel fuel. LVU-CD-10 en(us) Page 26 / 68

27 Working principle of the unit The applications are, for example: Portable and stationary emergency generators e.g. in hospitals, shopping centers, power plants. Tanks on portable machines, e.g. agricultural and forestry machinery. Storage tanks e.g. for agriculture and mining. Yachts and leisure boats. Filter element working principle The filter element works in two stages: Stage 1 Solid particle separation and drop coalescence By using purely synthetic filter media, a high contamination retention capacity and steady coalescence is guaranteed. Stage 2 Water separation A hydrophobic barrier layer on the screen tubing increases the size of the water drops which have formed. LVU-CD-10 en(us) Page 27 / 68

31 Unit setup/connection Unit setup/connection NOTICE Danger of tipping over / danger of slipping due to vibrations The unit will be damaged Prior to operation, place the unit on a stable, horizontal surface. Place the unit on a horizontal and level surface which is well ventilated. Install the suction port connection at the lowest part of the tank. This ensures that the water phase located at the base of the tank is reached. Install the return line as far as possible from the suction point in order to obtain an optimum intermixing of the tank contents. Prepare the unit for operation by following the following steps: 1. Check the connector cable for damage. If the connector cable is damaged, replace it immediately. 2. Check the connecting lines for leaks. Eliminate any leakages immediately. 3. Check and insert the filter element. See page 49 for details. 4. The unit is ready for the next steps on the following pages. LVU-CD-10 en(us) Page 31 / 68

32 Unit setup/connection Notes on pipes / hosing Make sure that no vibrations or stress/loading from other machinery and equipment are carried over to filter housing. If necessary, use expansion joints. The pressure loss in a hydraulic line depends upon: Flow rate Kinematic viscosity Pipe dimensions Fluid density The pressure loss can be estimated for hydraulic oils as follows: p p 6.8 * L / d 4 * Q * V * D = Pressure differential in [bar] L d Q V = Pipe length [m] = Internal pipe diameter [mm] = Flow rate [l/min] = Kinematic viscosity [mm²/s] D = Density [kg/dm³] Diesel has a density of approx kg/dm³ This applies to straight pipelines and hydraulic oils. Additional threaded connections and pipe bends increase the pressure differential. Keep the height difference between the pump and the oil level in the tank as low as possible. Constrictions in the connections and lines should be avoided. This could compromise suction output and cause cavitation. Take note that the nominal size of the connected hoses/piping must be at least as large as the inlet port sizes. Make sure that no vibrations or stresses are carried over to filtration unit when connecting the piping. Use hoses or expansion joints if necessary. LVU-CD-10 en(us) Page 32 / 68

33 Unit setup/connection Connecting the suction port (IN) For the suction port connection, use a flexible hose that is resistant to negative pressure. Avoid constrictions in the connecting lines, as they compromise suction performance and increase the risk of cavitation. NOTE Overpressure at the suction port connection The unit will be damaged The pressure on the suction port connection IN must not be more than -0.4 to 0.2 bar. Connecting the pressure port (OUT) Make sure that the nominal width of the pressure line corresponds to the connector thread of the filter housing. Install the return line below the fluid level to prevent air from entering the fluid in the tank If the clogging indicator pressure displayed for the a clean filter element is > 1 bar, use a differential pressure clogging indicator. NOTE Excess pressure at the pressure port connection The unit will be damaged The pressure on the suction port connection OUT must not be more than a maximum of 3 bar. LVU-CD-10 en(us) Page 33 / 68

34 Unit setup/connection Checking the water connection / water reservoir Check the water reservoir for damage. Empty the water reservoir completely and place the hose from the water outlet into the water reservoir. NOTE Excess pressure at the water outlet The filteration unit will be damaged Guide the water outlet into a depressurized reservoir. Electrical connection The filtration unit has a connector cable with a power plug. DANGER Exposed electric terminals in the terminal box of the electric motor Danger of fatal injury due to electric shock Any work involving the electrical system may only be done by a properly trained, certified electrician. Unwind the connector cable fully. Plug the power plug into a suitable, earthed, protected power outlet. Match the specifications for the power supply and frequency on the unit with the network specifications. The filtration unit has a thermal motor protection switch to protect it from electrical overload. LVU-CD-10 en(us) Page 34 / 68

35 Unit setup/connection Connecting the remote control line The unit has a connection for a remote control line. You can use this to start or stop the unit from a control centre. Unscrew both screws to the cover (615) for connection. Remove the cover (615). The description of the connection clamps can be found on the rear. Use a free screw type conduit fitting on the lower side to connect the control line. The line diameter must be at least 0.5 mm. Connect the control line on clamp X3 "Remote Start/Stop", "+" and "4".
