When installing the filter make sure that:
a) that sufficient space is available to remove filter element and filterhousing,

c) the filter is free of tension after installation
Preferably the filter should be installed with the filter housing pointing downwards. In this position the maintenance indicator is accessible and visible.
10.2 Connecting the electricalmaintenance indicator
The electrical maintenance indicator is connected via a 2-pole appliance plug according to DlN EN 17 5301-803 with poles marked 1 and 2. The electrical section can be inverted to change from normally open position to normally closed position or vice versa.

During cold starts, the indicator may give a warning signal.Press the 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.

The filter element should be replaced after trial run or flushing of the system. Afterward follow instructions of the manufacturer.
