Putting unit into operation
6.1
Filling of the unit
Caution!
For reasons of safety always pull the mains plug for
filling the cleaning liquid.
Shut the drain duct before you fill the tank.
Fill the cleaning tank with a sufficient quantity of a suitable
cleaning liquid before switch-on.
Observe the filling level marking inside the tank (
see Fig.
4.10.1.F
).
The level sensor must be immersed (
see Fig. 4.10.2.A
).
If the filling level goes down beyond a critical mark the unit is
automatically switched off by the level switch. This prevents dry
running of the unit which may cause damage to the equipment.
Fill the tank with aqueous cleaning media only:
Ensure that the chosen cleaning agent is suitable for treatment
in an ultrasonic bath and observe the instructions on dosage
and the compatibility of the material
.
The minimum conductivity
of the cleaning liquid must be 15 µSiemens/cm.
All flammable cleaning media are prohibited for use in an
ultrasonic bath. Please observe the safety warnings in
Section 8
(Cleaning media).
Risk of fire and explosion!
Never use flammable liquids or solvents directly in an ultrasonic
cleaning bath.
Ultrasonic activity increases the vaporisation of liquids and
creates a very fine mist which can catch fire on any ignition
source.
Observe the instructions on limitations of use given in
S
ection 8.1.
Risk of damage to the ultrasonic tank!
Do not use any acid cleaning agents (pH value < 7) directly in
the stainless steel tank if the cleaning items or the
contamination of the cleaning items contain halogenides
(fluorides, chlorides or bromides). The same applies to NaCl
solutions.
The stainless steel tank can be destroyed by crevice corrosion
in a very short time. Substances that cause crevice corrosion
can be contained in household cleaners.
Observe the instructions on limitations of use given in
S
ection 8.2.
For any queries please contact the manufacturer or your
supplier.
Danger of damage to the transducer system!
Fill no liquid > 60°C and < 10°C in the ultrasonic tank.
