Retro󹪝tting example "Suction operation, serial" operating mode for OXYMAT7/ULTRAMAT7
When you are using the ULTRAMAT7 and the OXYMAT7 analyzer module in serial suction
operation, you must convert the sample gas restrictor of the OXYMAT7 analyzer module:
Sample gas inlet → Sample gas outlet.

5.4.8 Enclosure purging
Enclosure purging
Gases can escape from the gas path on a very small scale and accumulate over a longer period
of time to dangerous levels. Therefore, the enclosure must be purged with dry, dust-free air or
inert gas when dealing with 󹪞ammable, toxic or highly corrosive sample gases.
Purge the wall-mounted enclosure with a 󹪞ow rate of approx. 1 l/min. Purging of the
enclosure can only be dispensed with if non-toxic gases or gas mixtures below the lower
explosive limit (LEL) are introduced into the device. Collect the gas displaced by the purging
using a suitable mechanism. Dispose of the gas in an environmentally friendly way, for
example, via an exhaust pipe.
