Attention: Dust-laden gases, deposits and condensed solvent vapour can restrict air flow out the si-
lencer. The resultant back pressure can lead to damage of pump bearings, diaphragms, and valves.
Under those conditions, a silencer must not be used.
Cleaning the pressure transducer
➨ Attention: Never use a spiky or sharp-edged tool to clean the pressure
transducer.
➨
Never touch the ceramic diaphragm of the pressure transducer with hard
objects.
➨ Fill the measurement chamber with a solvent (e. g. benzene) and allow suffi-
cient cleaning time. Observe all regulations concerning usage and disposal of
solvents!
➨ Drain the solvent and dispose of in accordance with regulations, repeat cleaning
if necessary.
➨ Rinse the measurement chamber several times with alcohol in order to remove
all solvent residues.
➨ Allow the pressure transducer to dry.
➨ Readjust the pressure transducer if necessary.
