ULTRAMAT 23 CSA with option E21
The sample gas exhaust lines must terminate outside the hazardous area at a harmless location.
The sample gas exhaust line can also be returned to the sampling point.
Ensure that the device is operated without pressure at the sample gas outlet.
For the introduction of flammable gases, purging with inert gas or comparable measures to
avoid an explosive atmosphere are recommended, because devices with seals are considered
devices with limited release according to international standards.
Risk of explosion due to accumulation of flammable gases
When the device is installed in an enclosure, an air exchange rate of at least once per hour must
be ensured.
Flammable components in sample gas
If the sample gas could contain flammable components, we recommend that you only use
devices with option - E21.

You must perform a leak test following all installation and maintenance work affecting the
containment system.
This leak test must be performed at regular intervals.
