If the calculated gas concentration of 3% is exceeded, the following measures are possible:
» Use of a smaller CO gas cylinder
2
» Increase in the size of the available room (e. g. by removing doors)
» Installation of a CO gas warning device in accordance with DIN 6653-2

» Installation of technical ventilation
Install CO gas cylinder

Note!
A functional check of the gas pressure reducer should be carried out before installing the CO
The CO pressure should be set at 4 bar. Depending on personal taste this can be set up to 5.5 bar. The
2
higher the pressure the more sparkling the water.
Before using new CO gas cylinders, the cylinder valve should be briefly opened and closed again to remove
2
contamination from the cylinder outlet valve. For hygienic reasons, it is also recommended to replace the
CO lines regularly.
2
The CO settings can also be adjusted via the BWT Professional App by qualified personnel.
2
Danger from CO
The CO gas cylinder is under pressure, open the valve only slightly and do not point it at people!
2
1. Check the gas pressure reducer for visible external damage (1).
2. Remove the thread protection cover from the CO
3. Screw the gas pressure reducer to the CO
4. Close the shut-off valve (2).
5. Open the gas cylinder valve and close it again (3).
6. Check for leakage.
7. Open the gas cylinder valve again (3).
