Inert gases in high concentrations is hazardous to health. They are colorless and almost odorless and
therefore practically imperceptible. Inhalation of inert gases can cause drowsiness up to respiratory ar-
rest. When the O
2
content of the air decreases below 18%, there is risk of death from lack of oxygen. Any
gas that might escape has to be led out via good room ventilation or a suitable exhaust system.
WARNING
High concentration of inert gas.
Risk of death by suffocation.

Do NOT set up units in non-ventilated recesses.
 Ensure technical ventilation measures.
 Respect the relevant regulations for handling these gases.
Inert gases, which are heavier than air, may accumulate in low-lying areas of the installation
site.
The mostly gas-tight version reduces the loss of gas.
Setting (example values):
If you want to flush the unit with an air exchange rate of 1 per hour, set the flow rate on the pres-
sure reducer according to the interior volume.
M 53 with 53 l internal volume: The flow rate corresponding to 53 l / h is 0.9 l / min.
M 115 with 115 l internal volume: The flow rate corresponding to 115 l / h is 1.9 l / min.
The air flap does not close the exhaust duct completely. The delivered plug serves to avoid loss of intro-
duced inert gas via the exhaust duct. Due to special demands of heat resistance, use the delivered plug
only.
CAUTION
Use of inappropriate plug.
Danger of inflammation.

Use only the supplied plug to close the exhaust duct.
For drying purpose, please remove the plug in order to permit dissipation of the generated vapor, which
would lead to condensation in the inner chamber.
