Procedure
Following procedure is valid for the UD+ and PDp+ filters:
1. Isolate the filter from the air net by closing the external inlet and outlet valve of the unit
(customer's installation).
2. Depressurize the filter by turning the connection nipple (6) of the automatic drain valve anti-
clockwise.
3. Unscrew the bowl (3). A whistling noise will warn you if the bowl is not fully depressurized. If this
occurs, the bowl should be screwed back and the venting should be repeated.
4. Discard the filter element (2).
5. Remove the drain valve (4) by unscrewing the retaining nut (5) underneath the bowl.
6. Remove the O-ring from the bowl and clean the bowl. Position a new O-ring on the bowl.
7. Remove the O-ring from the drain valve and position a new O-ring on the drain valve. The latter is
supplied with each new filter kit.
8. Reinstall the drain valve in the bowl using the retaining nut.
9. Reposition the new filter element with the new O-rings. Apply a small amount of water based
lubricant (supplied in the cleaning kit) on the O-ring and on the thread of the bowl.
