The electrical indicator is connected via a 2-pole appliance plug ac-

10.3 When should the filter element be replaced?
1 .
Filters equipped with visual and electrical maintenance indicat-
or:
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 im-
mediately pops up again and/or the electrical signal has not
switched off after reaching operating temperature the filter ele-
ment 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 flush-
ing of the system. Afterwards follow instructions of the manu-
facturer.
3 .
Please always ensure that you have original Filtration Group
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.

Operate and hold pressure equalizing lever located behind
switching lever. Pull catch knob and swivel switching lever.

no contamination occurs during the exchange of the element
first open the plastic bag and push the element over the spigot
in the filter head. Now remove plastic bag.

Push the element carefully over the spigot and tight cover until
full stop. Back off the cover 1/8 turn.
