16 MAINTENANCE
The safety instructions specific to the plant and process are to be consulted prior to any maintenance
work!
W A R N I N G !
Before starting maintenance work on electrical parts ensure that the
mains and the eventually connected alarm and control circuits are
switched off completely!
Maintenance cycles have to be carried out depending on your process or ambient conditions. An indi-
cation for a possible gas sample probe-maintenance could be a constant decline in the amount of
sample gas to the analysis system
.
Probe maintenance is restricted essentially on replacing or cleaning the pre-filter. The pre-filter can be
cleaned for example in an ultrasonics bath.
W A R N I N G !
High surface temperatures. Wear protective gloves!
To change or clean the pre-filter the gas sample probe has to be dismounted.
For this loosen the 4 screws at the flange and remove the gas sample probe from the process.
Unscrew pre-filter from the probe body and screw on the new or cleaned pre-filter.
17 CLOSING DOWN
Before switching off, that means switching off the heating, the M&C gas sample probe should be
flushed with inert gas or air in order to avoid condensation of aggressive components from the process
gas. After that, close gas outlet tight.
There are no other precautions to take.
