Manual and maintenance instructions
for INTERNORMEN-Coarse filter, change-over DGFK/EDGFK
This manual is effective for all filters of the type DGFK/EDGFK and related specifications. It contains certain requirements and
instructions which ensure unobjectionable operation of the filter. It can be completed with specific additional instructions by the operator
himself if necessary.
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 can not 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 any more!
- 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.
For filters being used in hazardous locations the INTERNORMEN documentation N° 41269 "Supplementation of the Operating
Manual for the use of filters in potential explosive areas.
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 according to DIN 2633 (or in case of special
design with specific flanges).
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 electronical clogging indicators have to be installed according to the unit specific conditions and
according to the technical parameters of the corresponding data sheets.

. Commissioning
Before commissioning the completeness of the filter (strainer basket 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 airbleeding 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 airbleeding tubes
-
Disconnection of the unit volume flow
-
Remove the airbleeding 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
The positioning pin of the selector shaft shows always in direction to the operating filter side.
