All parts must be arranged to avoid the formation of water pockets, e.g.
with slack or kinked tubing.
Select a suitable program (e.g. anesthesia program). Cleaning should take
at least five minutes at 40 – 60° C.
Cleaning is followed by thermal disinfection at 80–95° C. The dwell time
depends on the temperature of the disinfection program as follows:
Efficacy ranges:
A: Suitable for killing vegetative bacteria (including
mycobacteria) and fungi (including fungal spores)
AB: Same as A, and for the inactivation of viruses

automated cleaning and disinfection equipment and check the visible
surfaces for visible residual contamination. If necessary, repeat the
cleaning and disinfection process. After this, dry the treated parts
thoroughly (in a drying cabinet if necessary).
