Connected gas cylinders are classified as operating media and not hazardous substances (ADR release in compliance with sections 1.1.3.1 and 1.1.3.2. e). Gas cylinders that are not connected to gas installations always need to be closed and be fitted with protective caps.
The Truma gas remote switch allows the entire gas supply to be switched off comfortably from inside the vehicle at the push of a button. This does away with the need to go to the cylinder box and manually close the gas cylinders.
