Cleaning media
The cleaning chemical to be used must be suitable for the use
in an ultrasonic bath to prevent damage to the tank or injuries to
the user. Use the recommended cleaners mentioned in
section 8.3
. Observe the restrictions to cleaners containing
solvents and aqueous cleaners mentioned
in sections 8.1
and
8.2.
For queries please contact the manufacturer or your supplier.
Damages caused by non-compliance with the instructions given
in
sections 8.1
and
8.2
will not be covered by the
manufacturer's warranty!
8.1
Limitations of use of cleaners containing
solvents
Never use flammable liquids or solvents directly in an ultrasonic
cleaning tank. Risk of fire and explosion!
Ultrasound increases the volume of vaporisation of liquids and
creates a very fine mist that can catch fire on any ignition
source at any time.
Do
not
fill potentially explosive substances and flammable
solvents
marked in compliance with the EEC directives by symbols
and safety warnings R 1 to R 9
or E, F+, F, O or R 10, R 11 or R 12 for flammable
substances
into the stainless steel tank for ultrasonic treatment.
In compliance with the general regulations on the protection of
labour, certain limited volumes of flammable liquids (max.
1 litre) can be used in an ultrasonic cleaning unit under the
following conditions: these liquids must be filled into a suitable
separate vessel (e.g. beaker) with sufficient ventilation; this
vessel (beaker) can then be put into the stainless steel tank
which is filled with non-flammable liquid (water with a few drops
of surfactant).
8.2
Limitations on aqueous cleaners
Do not use aqueous cleaning media with pH values in the acid
range (pH < 7) directly in the ultrasonic tank if fluoride (Fˉ),
chloride (Clˉ) or bromide (Brˉ) ions can be taken in by the
removed dirt or through the cleaning chemical. These can
destroy the stainless-steel tank by crevice corrosion within a
very short period of ultrasonic operation.
