7.1
Servicing the water separator drain
Water separator drain (WSD)
Procedure
Once every six months, service the automatic drain assembly:
1. Isolate the water separator from the air net by closing the external inlet and outlet valve of the unit
(customer's installation).
2. Depressurize the separator by opening the manual drain valve on connection (4).
3. Unscrew the bowl (2). 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. Remove the drain valve (3) by unscrewing the retaining nut (5) underneath the bowl.
5. Check for clogging of the drain hole. Clean as required. Inspect the drain valve assembly.
6. Reinstall the drain valve in the bowl using the retaining nut.
7. Apply a small amount of water based lubricant (supplied in the medical cleaning kit) on the O-ring and
on the thread of the bowl. Screw the bowl completely on the separator head (1).
8. Repressurize and check for leaks.
