Operation
Avoid the formation of stains.
Proper instrument preparation can prevent resi-
due from being loosened from the load under
steam pressure during sterilisation�
Loosened remains of dirt can clog the filters,
nozzles and valves of the unit and settle as
stains and deposits on the instruments and the
chamber�
A single rusting instrument can be enough to
cause external rust to form on the other instru-
ments or in the unit�
All steam-conducting parts of the appliance are
made of non-rusting materials� This prevents the
formation of rust being caused by the unit�
i
Only use high-quality distilled or demineralised
water�
The extent of stains forming on the instru-
ments can also depend on the quality of the
fresh water�
