6.3.7 Cleaning the measuring chamber
Upper flange
The me
asuring chamber’s upper flange, which has been left in the
enclosure, can be cleaned using a lint-free cloth. Pull it to and fro through
the opening.
Upper measuring chamber section
Extract the dry temperature sensor (detach the white knurled nut and
carefully extract the sensor). You can now clean the vertical air duct using a
pipe cleaner or the like.
Attention:
When cleaning the air duct, take care not to damage or widen the hole.
Sharp-edged tools are not suitable!
Remove the pressure hoses and clean the holes of the hose nipples as well
as the side and vertical holes used for the pressure measurement. Again,
use a pipe cleaner.
Middle measuring chamber section and measuring cell
The interior of the measuring chamber often contains just greasy dirt. The
measuring cell may contain sludge.
In most cases, such dirt can be removed using a soap solution or household
washing up liquid. Glass cleaning agents, as used in chemical laboratories,
are also quite suitable.
If the dirt proves to be hard to remove, you should look for a suitable solvent
for the relevant type of dirt (for instance, benzine for deposits of substances
such as tar).
The materials used in the measuring chamber are highly resistant to
corrosion and solvents, which means that even substances with intensive
effects can be used. If in doubt, please consult your service centre.
You should preferably clean the middle section of the measuring chamber
using a soft cloth and the bottom of the measuring chamber using a brush,
together with a detergent.
