Replacing the filter element
Hazard due to a sudden release
of pressure!
Depressurise the filter before carrying
out any work on the filter! A sudden
escape of pressure may cause seri-
ous injuries.
- Block compressed air supply to the filter.
- Depressurise the filter. To do so, you may
have to open the condensate drain at the
filter bottom.
- Give the lower housing a full turn in clock-
wise direction and take it off downwards
(Figure 5).
- Take out the filter element and dispose of
it according to the operating instructions.
- Replace seal (Figure 6).
- Insert the new filter element: The lugs fit
the recesses in the lower housing exactly
and ensure the correct seat of the filter
element (Figure 7).
- Apply a thin coat of grease on the thread
of the lower housing.
- Using the marks, vertically align the lower
section with the upper section of the
housing and fully close off with one com-
plete turn (Fig. 8).
- If necessary, close the condensate drain
and open the pipe to the filter.
- Check the filter for tightness.
