General notes in accordance with BGR 228
The gas detection system installer is responsible and therefore liable for the correct
installation and handover of the equipment.
Gas detection devices (equipment requiring special monitoring) may only be planned,
installed and maintained by specialist personnel.
To ensure safe operation, only ancillary components approved by KUNDOxT may be
connected to the CO2 CONTROL safety system.
BGR 228 /DIN 6653-2 stipulates all of the statutory measures and the state of the art for the installation and operation of gas detection equipment in dispensing
systems.
DIN EN 378 refers to the state of the art for the application, operation and functional checking of gas detection devices in the refrigeration field.
The rules therein must normally be observed and complied with. All further measures for the installation/assembly of the CO2 CONTROL gas detection system
are given in the sections below.
