1. Intended use The two versions of the mobile filter unit UFM 41 according ti the technical parameters of the data sheet 4006 are designed for the fine filtration of operating fluids with dirt particles 200 Micron. Larger particles may lead to premature wear of the gearpump. 2. Commissioning The filter unit is supplied and delivered ready for operation: - The filter unit is not connected to the electric network. - The motor protection switch is shut off. - The suction and discharge hoses are wound up and the lances are in their respective locating tubes. - The unit is equiped with a filter elemet. - The draining and airbleeding screws and the filter lid are closed. - The filter housing holds roughly 5 l of operating fluid left over from the previous filter process. (It is recommended to mark a reference to the last filtered operating fluid on the filter unit). Before each commissioning the cleanliness of the lances, particulary that of the discharge hose, must be checked. Contaminated lances are to be cleanes with solvent before they are lowered into the fluid that is going to be filtered. The suction and discharge hoses are lowered into the respective tanks. During the operation of the filter unit the lance of the suction hose must be immersed in the fluid up to 50mm minimum. Make sure that the fluid that is to be filtered can easily enter and exit the lances of the hoses. Connect the filter unit the electric network (Note working voltage and kind of current!). The unit is turned on and off by means of the motor protection switch. After operating the unit or after maintenance and repair works the initial state has to be restored. 3. Changing the element The filter element must be exchanged when the clogging indicator shows a pressure of 6 bar. For the exchanging of the element the filter unit has to be in initial state. The drain screw „E3“ and the airbleeding screws „E1“ are opened and the fluid left over in the filter unit is drained into the oil tray. The fluid gathered in the oil tray is to be treated as contaminated fluid. It is cleared from the oil tray by inclining the entire unit. When no more fluid emerges from the drain holes, the lid of the filter unit is opened and the filter element can be taken out, Depending on the degree of contamination, the filter housing has to be cleaned before the new element can be inserted. The exchange element is taken out of ist wrapping just before it is inserted into the housing. The element must be checked on ist integrity (no visible mechanic damages) and ist completeness (O-ringes in the circular groove of the element). After insertion of the new filter element into the housing, the lid is put on and tightened by means of the locknut (torque: 60Nm). During the entire process of exchanging of the element particular attention has to be paid to preventing the contamination of either the filter element or the housing. Finally, the drain and aurbleeding screws are tightened. 4. Cleaning the filter housing After the filtration of heavily contaminated fluid and when visible dirt particles are found in the filter housing, a thorough cleaning of the latter becomes necessary. The housing is cleaned upon the exchange of the filter element. The drain screw „E3“ is opened. The inside of the housing is cleaned with conventional brushes and detergents. During the entire cleaning process make sure that no dirt particles get to the inside of the element (clean-oil side)(drill hole diameter 55 of the locating peg) and that no solvent remains in the housing. 5. Venting Generally, a separate airbleeding is not necessary. At a pressure of 6 bar the air blocked in the filter housing cannot dissolve into the fluid and is evacuated ba the discharge hose. In case a separate airbleeding connection is required ba the user, the filter unit is to be equired with a airbleeding unit according to data sheet no. 1650. Order reference of the airbleeding unit: - mini measurement connection MA.3.ST - high pressure hose M16.630 (length 630 mm) or - high pressure hose M16.2000 (length 2000 mm) - spray protection M16 6. General information - Every time the lid of the housing has been opened, the condition of the flat gasket 162x144x2 has to be checked. Damaged gaskets have to be replaced. - Torque of locknut: 60 Nm. - Filter units with mototr protection switch shut themselves off automatically after 5 min. of an operating pressure of 6 bar.

1. Intended use
The two versions of the mobile filter unit UFM 41 according ti the technical parameters of the data sheet 4006 are designed for the fine
filtration of operating fluids with dirt particles 200 Micron. Larger particles may lead to premature wear of the gearpump.
2. Commissioning
The filter unit is supplied and delivered ready for operation:
- The filter unit is not connected to the electric network. - The motor protection switch is shut off. - The suction and discharge hoses are wound up and the lances are in their respective locating tubes. - The unit is equiped with a filter elemet. - The draining and airbleeding screws and the filter lid are closed. - The filter housing holds roughly 5 l of operating fluid left over from the previous filter process. (It is recommended to mark a reference to the last filtered operating fluid on the filter unit).
Before each commissioning the cleanliness of the lances, particulary that of the discharge hose, must be checked. Contaminated lances are to be cleanes with solvent before they are lowered into the fluid that is going to be filtered. The suction and discharge hoses are lowered into the respective tanks. During the operation of the filter unit the lance of the suction hose must be immersed in the fluid up to 50mm minimum. Make sure that the fluid that is to be filtered can easily enter and exit the lances of the hoses. Connect the filter unit the electric network (Note working voltage and kind of current!). The unit is turned on and off by means of the motor protection switch. After operating the unit or after maintenance and repair works the initial state has to be restored.
