During cleaning, water-polluting substances, e.g. oils or heavy-
metal compounds, can contaminate the sonication fluid depending
on the type of soiling. If the limit value for these substances is
exceeded, the sonication fluid must be reprocessed or disposed of
as special waste.
Observe the local waste water regulations.
2.11 Erosion of the ultrasonic oscillating tank
The surface of the ultrasonic oscillating tank is subject to erosion.
How quickly this erosion takes place depends on the usage of the
ultrasonic bath. The erosion leads to leaks in the ultrasonic oscillat-
ing tank. Sonication fluid can thus leak into the interior of the ultra-
sonic bath. Moisture on electrical components can lead to an
electric shock or to a fire.
• Do not use the ultrasonic bath any more if you notice a leak. Dis-
connect the mains plug immediately. Empty the ultrasonic oscil-
lating tank.
You can extend the service life of the ultrasonic oscillating tank by
observing the following information:
• Change the sonication fluid when it is noticeably contaminated
with particles.
• Use only demineralised water with an agent suitable for ultra-
sound.
• Do not use any chemicals in the ultrasonic oscillating tank that
contain or release chloride ions. This is the case with some dis-
infection agents, household cleaning products and detergents.
Chloride ions cause corrosion on stainless steel.
• Use the ultrasonic bath exclusively with accessories that are
suitable for the ultrasonic bath and the goods to be treated, e.g.
a basket. Do not place any goods to be treated directly on the
bottom of the ultrasonic oscillating tank. You will find an over-
view of suitable accessories in chapter
