The pressure filter with change-over valve, type DSF/EDSF 1201-15001, DSF/EDSF 1205-10005 are designed for filtration of
operating fluids according to the technical parameters of the data sheets (or in case of special design the corresponding data
sheet).
1. Safety instructions
- Prior to operating the filter, manual and maintenance instructions have to be read carefully.
- Follow the instructions of this manual under any circumstances!
- The manufacturer does not assume liability for any damage, which occurs due to disregarding these instructions.
- If operations are carried out differently, the safety of the pressurized device cannot be assured!
- Operating conditions given in the data sheet, especially excess pressure, temperature range and operating fluid, have to be
followed unconditionally. Variation of these parameters can cause damage to important pressure holding parts and sealing. Also
take in consideration the compatibility of filter components with the operating fluid.
- Under working conditions the filter housing is pressurized. Do not try to loosen or remove any part of the filter or the filter housing
during operation. The operating fluid could escape at high pressure and high temperatures.
This does not apply for parts of the decompressed or the turned off side of the filter (see „Maintenance“).
- Leaking operating fluid always bears the danger of injuries and burns!
- Do not open the filter housing until you made sure it is not pressurized anymore!
- Touching parts of the filter may cause burning, depending on the operating temperature.
- When exchanging the filter keep in mind that it might have operating temperature. Danger of burning!
- Always wear safety goggles and gloves when working on the filter!
- If you come into contact with the operating fluid please follow the instructions of the fluid manufacturer!!
- Only use original spare parts.
2. Installation
The filter is supplied and delivered ready to be installed. The fitting position of the filter is vertical. The filter has to be fitted with
fastening screws in size and amount according to the corresponding fastening bore holes of the filter housings. The fitting of the
filter has to be carried out in the way that the least possible transmission of tensible forces on the filter housing and the change-
over valve is given. The connection of the pipework has to be made with flanges for pipework.
Ensure upon assembling that
- no dirt and no impurities of foreign fluids penetrate the filter
- the connections for input and output are correctly connected to the pipe system
- the pipe system is connected with the filter; as stress-free as possible
- the extension to demount and the accessibility to the service elements is guaranteed
Filter with electrical respectively electronic clogging indicators have to be installed according to the unit specific conditions and
according to the technical parameters of the corresponding data sheets.
3. Commissioning
Before commissioning the completeness of the filter (filter elements and seals) and the cleanness have to be controlled.
Air bleeding of the controlled filter has to be carried out to the following instructions:
- The positioning pin of the selector shaft has to be located in the middle position
- Opening of the air-bleed screws or air-bleed connections (air-bleed connections according to data sheet 1651 and
connection of suitable air bleeding tubes with coolecting pan for the flow out of the operating fluid
- Connection of the unit volume flow (reduced volume flow; from 10 to 50 l/min) until bubble-free operating fluid flows out of
both air bleeding tubes
- Disconnection of the unit volume flow
- Remove the air bleeding tubes and close the air-bleed bore holes or air-bleed connections (air-bleed connections
according to data sheet 1651)
- Connection to the required filter side at the positioning pin of the selector shaft (see instruction plate at filter)
4. Change of Elements
The changing of the filter elements is necessary when reaching the unit specific pressure difference respectively reaching the
maximum pressure difference given by the clogging indicator. If there is no unit specific definition, the change of the elements
should be done at a maximum of
p 6 bar.
This has to be carried out as follows:
- Opening of the pressure balance valve
- Switching over the positioning pin from the operating side through the other side
- Closing the pressure balance valve
- Connect the air-bleed and the drain plug of filter side to be maintained with suitable pipes and place a collecting pan for the
operating fluid flowing out
- Opening of the air-bleed and drain plugs of the filter side to be maintained until no more operating fluid flows out
- Release of the screws of the lid of the filter side to be maintained and remove the filter lid
- Remove the retaining plate for the filter elements (DSF/EDSF 1201-15001)
