WARNING
Danger of explosion and poisoning when introducing gases/sub-
stances other than CO
2
and N
2
. Only carbon dioxide (CO
2
) and ni-
trogen (N
2
) may be introduced into the appliance through the gas
connections on the rear of the appliance.
WARNING
Gas bottles may burst or explode at high temperatures. Keep the gas
bottles away from open fl ames. Do not store gas bottles at or above
50 °C and ensure that the location is always well-ventilated. Prevent
water from penetrating as well as backfl ow into the gas bottles. It is
essential that you read the safety notes and instructions of the gas
supplier.
CAUTION
Danger of suffocation. CO
2
and N
2
can have a suffocating effect
in high concentrations. In normal mode, the appliance emits small
amounts of CO
2
and N
2
to its surroundings. You should therefore
ensure that the room in which it is installed is properly ventilated.
A ventilation rate of 250 m³ / h is required. Always close the stop
valve or pressure reducer on the gas bottles if the appliance is not in
operation.
