5.0 Cleaning
5.1 General information on
cleaning and disinfection
The jet connection which comes into contact with the
patient must be disinfected after each use.
The hose tips must be exchanged after each use.
The surfaces of the
Variotherm plus
resist most of the com-
mon surface disinfectants.
However, do not use
– disinfectants containing concentrated organic or anor-
ganic acids or bases, since these may cause corrosion
damages;
– disinfectants containing chloramides, phenol derivatives or
anionic tensides, since these may cause stress cracks in
the plastic material used for the housing of the unit.
For cleaning and disinfection, you may also use disinfectant
sprays or disinfectant tissues.
Switch off the ENT unit by the main switch before
starting cleaning and disinfection.
Wipe the unit surface with a cloth moistened with a
cleaning or disinfecting solution. Make sure that no liquid
penetrates the unit. You may use all cleansers and
disinfectants listed in section 5.3.
Spilled liquid must immediately be dry wiped.
Always observe the instructions for use by the manu-
facturer of the disinfectants, above all, concentration
specifications.
The above measures for cleaning and disinfecting do
not replace the respective precautions for operating
the unit.
