Operating Instructions HYGROPHIL® H 4230-12 BA 060207
Be careful with the measuring cell. The ceramic ring in the measuring cell is
brittle and can therefore be broken easily.
Lower measuring chamber section with ejector
You should not dismantle the ejector because it is adjusted at the factory in
order to maximize efficiency.
If you notice that the consumption of compressed air is rising or if the mes-
sage „FLOW TOO LOW“ appears although the supply of compressed air is
sufficient and the station pressure is ≤ -200 hPa, this means that the ejector
is not working properly.

Clean the lower section of
the ejector by inserting pipe
cleaners from the under-
side.
 You can remove any dirt al-
so from the ejector outlet
using a bundle of pipe
cleaners.
If this does not rectify the fault, any dirt may be deposit inside of the ejector.
This can impair the flow. To remove this dirt and coat you must open the
ejector.

Loosen the three screws and re-
move the lower part of the ejector.
