b) Only use the product in the specified limit values for pressure and withdrawal quantity.
c) Usage for another type of gas or outside the limit values is prohibited and constitutes mis-
use.
WARNING
Noise emission
When working on pressurised pneumatic supply, significant noise emission can occur. Acute
and chronic loss of hearing may result.
a) Never perform work on the pressurised pneumatic supply without hearing protection.
b) Only replace the silencers when the supply is unpressurised.

Displacement of atmospheric oxygen
In the event of inert gas leaks, displacement of atmospheric oxygen may occur. Danger of suf-
focation!
a) The operator must ensure adequate ventilation and airing in all rooms with gas installations
and monitor the oxygen content.
