5 Cleaning and maintenance of the ultrasonic bath
To achieve an optimum lifespan for the ultrasonic bath, cleaning and maintenance are to be
conducted regularly. Following are instructions for manual cleaning and care.
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.
5.1 Cleaning and care
Liquid circuit
The contact liquid circuit runs, during operation, from the tank's outlet through the pump to
the cooling unit, and from there back to the tank . For reasons of hygiene, this circuit must
be regularly
fl ushed.
 Fill the oscillating tank with liquid , see chapter 4.1.
 Turn on the ultrasonic bath. The internal pump starts working automatically and
thoroughly fl ushes the ultrasonic bath.
 Allow the pump to run for at least 5 minutes (without ultrasound).
 Turn o ff and empty out the ultrasonic bath, see chapter 4.4.

Repeat the described rinsing process two to three times.
 After the last emptying, wipe dry the oscillating tank using a soft cloth.
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 due to the movement of the
fl uid, therefore
• Thoroughly and frequently rinse the oscillating tank with water and rub dry using a soft
and lint-free cloth. If needed, conduct the rinsing process in accordance with chapter
6.3.2.1.
• 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.
• Rust particles from the water pipe system can penetrate the passive protective layer
of the stainless steel, thereby "activating" the stainless steel, which will cause it to rust.
The extraneous rust produces localised corrosion of the stainless steel. For this reason,
remove rust stains immediately using a soft cloth and a commercial stainless steel
cleaning product without abrasive additives.
