Do not apply force to gas bottles, bottle connectors and valves.
When transporting, storing, and using the gas bottle, prevent it
from falling over and dropping by securing it with chains, hoops,
or retaining straps.
Only transport gas bottles with the valve guard fitted: bottle cap
or bottle collar.
Operate and store the CO
2
bottle upright.
Do not place the CO
2
bottle close to a heat source. Heaters or air
conditioners are examples of heat sources. Do not actively heat
the CO
2
bottle, e.g. using a fan heater. Do not expose the CO
2
bot-
tle to direct sunlight.
Observe the safety instructions provided by the gas supplier.
Preparing and checking the gas
bottle
1. Make sure that the gas bottle contains CO
2
. Check the label on the gas bottle.
2. The gas bottle may only be operated upright. Secure the gas bottle using retain-
ing straps, chains, etc. to prevent it from falling over.
3. If you have stored the gas bottle at below 15 °C or over 25 °C, allow the gas bottle
to acclimatize at room temperature for 8 hours. Do not actively heat the gas bot-
tle, e.g. using a fan heater.
4. The room temperature should be between 15 °C and 25 °C. It is possible that
these values may be exceeded or may not be reached for a short period, as the
gas bottle only heats up or cools down slowly.
5. Check the thread of the bottle valve for damage.
6. Do not apply force to the gas bottle, gas bottle adapter, the switch valve and the
bottle valve.
Connecting the switch valve and
gas tube
Refer to the assembly instructions 80114-505 when connecting the gas bottle adapt-
er, the switch valve and the gas tube.
1. First connect a gas bottle adapter to both gas bottles. Observe steps 1 to 5 for
your country-specific gas bottle adapter when doing this.
2. Connect the switch valve to both gas bottle adapters.
3. Connect the gas tube to the switch valve.
4. Connect the free end of the gas tube to the unit (see Connecting the gas tube to
the gas connection p. 32).
5. Turn the tap with the arrow towards the full gas bottle.
6. Switch on the unit and press the Info button.
7. Open the bottle valve fully and note the input pressure that is displayed.
8. Close the bottle valve and monitor the pressure for approx. 120 seconds. The
pressure may only fall by max. 2 bar. If the fall in pressure is greater, one of the
connections is not leak-tight. Inform Technical Service. Do not work with a leaky
gas connection.
Changing gas bottle (when using a gas bottle adapter)
Disconnecting gas tube and gas
bottle adapter
1. Close the bottle valve.
2. Loosen the gas tube on the gas bottle adapter slightly. The gas escapes from the
gas tube. Fully disconnect the gas tube. Disconnect the gas bottle adapter. Follow
the corresponding circuit diagrams in assembly instructions 80114-805 when
