10.1 Filter installation When installing the filter make sure that sufficient space is available to remove filter element and filter housing. The maintenance indicator must be visible. |
| 10.2 Connecting the electrical maintenance indicator The electrical indicator is connected via a 2-pole appliance plug according to DlN EN 175301-803 with poles marked 1 and 2. The electrical section can be inverted to change from normally open to normally closed position or vice versa. |
| 10.3 When should the filter element be replaced? |
| 1. Filters equipped with visual and electrical maintenance indicator: During cold starts, the indicator may give a warning signal. Press the red button of the visual indicator once again only after operating temperature has been reached. If the red button immediately pops up again and/or the electrical signal has not switched off after reaching operating temperature the filter element must be replaced after the end of the shift. |
| 2. Filters without maintenance indicator: The filter element should be replaced after the trial run or flushing of the system. Afterwards follow instructions of the manufacturer. |
| 3. Please always ensure that you have original MAHLE spare elements in stock: disposable elements (Sm-x) cannot be cleaned. |
10.4. Element replacement Note: The maintenance indicator monitors the filter side in operation, which is identified by the position of the switching lever catch. The change-over transfer valve must be switched prior filter servicing. Now the signal of the maintenance indicators cancelled and the red button can be repressed again.
