9.2 General notes
Cleanliness is a prerequisite for the success of an oxygen therapy at home. The specified
cleaning intervals must therefore strictly adhered to!
Do not use lubricants other than those recommended by the manufacturer.
External contamination of the gas path is possible due to the design from the outer gas outlet
to the internal check valve including silicone tubing.
