2. CONNECTING GAS PRESSURE REDUCER
1. Connect a food-safe hose to the existing ¼" metal push-fit connection on the gas pressure reducer.
If necessary, replace the ¼" metal push-fit connector that has already been screwed in with the
5/16" metal push-fit connector. Depending on the available installation space, the appropriate elbow
connector (2 or 3) can be used to attach the hose to the CO
or to connect it at 90° to the inlet of the water dispenser system.
2. Connect the food-safe hose at the CO
3. Fix the appropriate circlips (4 or 5) at every connection.
4. Open shut-off valve (A).
5. Check system for leaks.

3. CALCULATE CO GAS CONCENTRATION
2
Caution!
For safety reasons, in case of a gas leak, the CO₂ concentration in the room must not exceed 3%.
During the installation of the CO gas cylinder, it is recommended that the maximum CO
2
content should be determined beforehand in accordance with the available room size or available
room volume.

If the calculated gas concentration of 3% is exceeded, the following measures are possible:
» Use of a smaller CO
» Increase in the size of the room (e. g. by removing doors)
» Installation of a CO
» Installation of technical ventilation
The CO gas concentration is calculated as follows:
