Cleaning And Care; Treatment Of Medical Instruments - Bandelin Sonorex Super Mode D'emploi

3.2. Cleaning and care

- Be sure to pull the plug before cleaning the unit.
- Do not shower the units or immerse them in water; instead, wipe them with a damp cloth, in-
and outside.
- Rinse out the stainless steel tank frequently and wipe it dry.
- Do not use steel wool, scrapers or graters.
- If rings should appear in the stainless steel tank after a longer period of operation, remove them
with a customary stainless steel cleaner without scouring additives.
- Metal parts remaining on the stainless steel surface, as well as particles of rust, can penetrate
the passive protective layer of the stainless steel, thereby "activating" it and causing it to rust.
This rust provokes pittings on the stainless steel surface. Therefore, remove all remaining metal
parts such as screws, metal chips and the like; remove minor rust spots immediately with a soft
cloth and customary stainless steel cleaners without scouring additives.
SONOREX units do not require maintenance.

3.3. Treatment of medical instruments

- If the ultrasonic cleaning unit is used in connection with disinfectants (medical device, class
IIa) in order to support or to accelerate disinfection, then the ultrasonic unit is considered an
accessory for a medical device and must be classifi ed itself as medical device, class I!
- When disinfecting and cleaning contaminated medical instruments in an ultrasonic bath,
the hygienic safety is important after the treatment. In case of improper and irregular
disinfection and cleaning a micro-biological contamination is possible caused by settlement
of microorganism, especially at the tank rim or in the drain section. Cross infection might be a
result. Therefore, the tank and housing surfaces must be regularly disinfected and cleaned.
According to the hygienic plan the user must carry out regular disinfection and cleaning with a
surface disinfecting agent certifi ed by VAH/DGHM*, or another effi ciently classifi ed agent.
- The instruments may not be placed on the tank bottom. The basket avoids damages at the
instruments and at the tank bottom. Do not staple instruments, overloading reduces the
cleaning effi ciency. Pliers and scissors must be opened completely or detached, if necessary.
Instruments must be completely covered with cleaning liquid, air has to escape from cavities
and hoses.
