MAINTENANCE
Fig. 63: Replacing the purge air filter element
1 Have a new filter element available.
2 Remove the filter housing cover by releasing the two snap locks on the side.
3 Pull the filter element, turn counterclockwise, out of the filter housing.
4 Clean the inside of the filter housing using a cloth and brush. Use only water and no
detergents at all because detergent deposits can falsify measurement results later.
>>>
If it is still uncertain whether the filter element is to be replaced:
▸ Check the filter element for deposits, without creating any dust clouds.
▸ If the filter element is not contaminated significantly, it can be reinstalled instead of a
new filter.
5 To install the new (or previous, uncontaminated) filter element, secure it to the spindle in
the filter housing by turning/pressing it counterclockwise.
6 Fit the filter housing cover and align it with the filter housing so that the two snap locks
on the side click into position.

NOTICE: Correct handling during filter maintenance
– Avoid creating dust clouds to prevent any contamination penetrating the
measuring system.
– Do not use any detergents because deposits will falsify measurement
results. Use clean cloths, that can be moistened with water only, when
necessary.
