16.1 REPLACEMENT OF FILTER ELEMENT AND SEALS
W A R N I N G !
Before carrying out any maintenance or repairs, it must be ensured
that no health-endangering contaminants remain in the probe. A
suitable measure is, e.g. purging the probe with inert gas.
The bypass respectively primary injector air supply should be
turned off before the probe filter lid assembly is removed. Other-
wise the critical orifice will be blocked by dust !
For change of the filter element respectively gaskets carry out the following steps:
Close ball valve (if available).
Close dilution gas supply and, if available, bypass gas supply.
Remove protective cover after loosening toggle-type fasteners.
Loosen stirrup bolt, swing retaining bracket to the left, grip filter holder by the ring and withdraw.
