10.1 Filter installation
When installing the filter make sure that sufficient space is available
to remove filter element.
The maintenance indicator (*4) must be visible.

10.2 Connecting the electrical maintenance indicator
The electrical indicator is connected via a 2-pole appliance plug ac-

trical section can be inverted to change from normally open to nor-
mally closed position or vice versa.

10.3 When should the filter element be replaced?
1 .
Filters equipped with visual and electrical maintenance indicator
(*4) :
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 (PS) cannot be
cleaned.
10.4 Element replacement
Note: The maintenance indicator (*4) monitors the filter side in oper-
ation, which is identified by the position of the switching lever catch.
The change-over transfer valve must be switched prior filter servi-
cing. Now the signal of the maintenance indicators cancelled and the
red button can be repressed again.
1 .
Operate and hold pressure equalizing lever (*2) located be-
hind switching lever. Pull catch knob and swivel switching lever.
Place through or drip pan underneath to collect leaving oil.
Close pressure equalization valve.

max. until contact is made with the safety stop.

Make sure that the order number on the spare element corres-
ponds to the order number of the filter name-plate. To ensure
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.
