Before cleaning any surface, make sure that it has cooled down.
5.1.1 Cleaning the sterilisation chamber and internal components
Use a soft cloth soaked in water to avoid damaging the protective
surface treatment of the chamber. Rinse thoroughly with water and
then dry. If necessary, moisten the cloth with white vinegar to re-
move any limescale.
However, we recommend cleaning the chamber only when strictly
necessary. If there are limescale deposits, immediately check what
is causing them. White patches forming at the bottom of the cham-
ber means that the water used is of poor quality or does not comply
with the required specifications.
5.1.2 Cleaning the door cover
Use a soft cloth soaked in water to avoid damaging the protective
treatment of the door cover. Rinse thoroughly with water and then
dry. DO NOT USE metallic or particularly abrasive cloths for clea-
ning. Using them could damage the external surface of the door
cover.
5.1.3 Cleaning the external front panel
Use a soft cloth soaked in alcohol, taking care not to let it penetrate
into the autoclave internal parts. Never use detergents based on
trilene, benzene or turpentine or solvents of any kind. DO NOT USE
metallic or particularly abrasive cloths for cleaning.
5.1.4 Cleaning the door seal
Clean the seal with a soft cloth moistened with water or white vine-
gar, to remove any limescale. Rinse thoroughly if you used vinegar.
This procedure serves to remove impurities that can cause pressure
loss in the sterilisation chamber and possibly break the seal.
5.1.5 Cleaning the filter in the chamber
- Remove the tray holder with the trays from the chamber
- Rinse the filter thoroughly with water.
- Reposition the filter on the bottom of the chamber and screw it
back in place.
If the cleaning operation does not produce satisfactory results, call
DÜRR DENTAL Technical Support.
