Changing the Filter Element
TIP
The unit must always be switched off when the filter element is changed.
Pull the power plug!

!
The filter bowl must be depressurized, meaning that
the pressure gauge integrated in the cover plate has
to display "0" bar = the housing is at zero pressure.
If this is not the case, release the pressure by opening the vent plug in the cover
plate.
Depending on the type of installation of the unit, a certain amount of oil can remain
in the filter bowl; this can be drained via the drain plug.
No tools are required to change the filter element. The four toggle screws in the
cover plate are loosened and the eyebolts are pulled down, which pushes the filter
housing cover plate upwards. It can then be removed by hand. Then the filter
element is pulled off the spigot.
TIP
There is a cap on top of the filter element. It seals the bypass valve of the
filter element, and prevents contaminated oil from flooding during a cold
start or when the element is completely clogged. The cap must be replaced
on the new filter element.
Then the new filter element is pushed onto the spigot by turning it slightly. It is
advisable to lubricate the O-ring of the
filter element in the spigot bore as this
will make fitting easier. Replace the
cover, push the star knobs up and
tighten them evenly to secure the cover
to the filter housing.
