Cleaning and maintenance of the ultrasonic bath  

To achieve an optimum lifespan for the ultrasonic bath, cleaning and maintenance are to be 
conducted regularly.

CAUTION! 

Disconnect the ultrasonic bath from the mains before cleaning / maintenance.

Do not rinse or immerse the ultrasonic bath in water, and do not expose it to splash water. 

No guarantee will apply to damage caused by the use of unsuitable surface disinfection 
agents or detergents. 

5.1 

Cleaning and care  

Oscillating tank

The oscillating tank of an ultrasonic bath is a wear part. 
It is continuously exposed to cavitation during ultrasound operation. Dirt particles remaining in the 
tank abrade and damage the tank surface through the movement of the 

fl

 uid, therefore

•  Thoroughly and frequently rinse the oscillating tank with water and rub dry using a soft cloth.
•  Regularly remove residue from the edges of the oscillating tank using a commercial stainless 

steel cleaning product without any abrasive additives. 

•  Do not use steel wool, scrapers or graters for cleaning / maintenance.
•  Metal particles that remain on the stainless steel surface as well as rust particles from the 

water pipe system penetrate the passive protective layer of the stainless steel. The stainless 
steel is "activated" in this process and it begins to rust. The extraneous rust produces localised 
corrosion of the stainless steel. For this reason, remove metal parts such as screws, 

fi

 lings, 

etc. from the oscillating tank, and immediately remove rust stains using a soft cloth and a 
commercial stainless steel cleaning product without abrasive additives.

Housing

•  Do not use any abrasive cleaners, only commercial care products without abrasive additives.
•  Housing is to be wiped off only from the outside with a moist cloth; afterwards, allow to dry alone 

or wipe dry.

5.2 

Disinfection for medical applications  

If contaminated medical instruments are treated in the ultrasonic bath, hygienic safety after the 
application is important. In order to avoid any cross-contamination as a result of the colonisation 
of microorganisms, especially along the tank edge and in the drain outlet area, but also on the 
operator panel, these areas are to be regularly cleaned and disinfected with a suitable surface 
disinfectant, i.e. one that is at least bactericidal, yeasticidal and virucidal against enveloped 
viruses.
Accessories such as holders and baskets should be processed regularly in a cleaning and 
disinfection unit.

5.3 

Warehousing / storing  

During long periods of non-use, the ultrasonic bath is to be stored in a cool, dry location. The lid 
should be placed on top in order to protect the oscillating tank from outside contamination.
