Ultrasonic energy emitted through the air is not hazardous to
your health. However, high sonic emissions do arise during
ultrasound operation that may, under circumstances, cause
hearing damage to the foetus.
We recommend pregnant people not to spend long periods of
time near an ultrasonic cleaning device.
Elma Schmidbauer products with the CE mark comply with the
European EMC and Low Voltage Directive and adhere to the
prescribed EMC limit values so that the electromagnetic
radiation emitted by the devices is harmless to healthy people.
A binding statement for people with implants, such as those
with cardiac pacemakers or implanted defibrillators, can only be
made at the specific occupational site and upon consulting the
manufacturer of the implants.

Functioning

BA_Elmasonic S_EN_Vers. 05.2019

3 Functioning
Today, cleaning by ultrasound is the most modern fine cleaning
method.
The electric high-frequency energy created by an ultrasonic
generator is transformed into mechanical energy by piezo-
electrical transducer systems and is then transmitted into the
bath.
This process creates millions of tiny vacuum bubbles which
implode due to the variations of pressure caused by the
ultrasonic activity. Highly energetic liquid jets are created. These
jets remove dirt particles from surfaces and even from the
smallest grooves and bores.
3.1 Ultrasonic cleaning factors
Basically, the cleaning result depends on four factors:
Ultrasonic energy is probably the most important mechanical
factor in the cleaning process. This energy must be transmitted
through a liquid medium to the surfaces which are to be
cleaned.
The present Elmasonic unit is fitted with the innovative sweep
function device: electronic oscillation of the sound field (sweep
function) prevents the formation of zones of low performance in
the ultrasonic bath.
For saponification and removal of the dirt particles a suitable
cleaning agent is required. Elma has a large range of cleaning
media on offer.
Cleaning chemicals are also necessary to reduce the surface
tension. This increases considerably the efficiency of the
ultrasonic activity.
The effect of the cleaning medium is improved by the optimised
temperature of the cleaning liquid.
For Elma cleaning products please observe the instructions
given on the label or the product information leaflets.
The cleaning period depends on the degree and the kind of
contamination and on the correct selection of ultrasonic energy,
cleaning agent and temperature.

6.1 Filling of the unit
Shut the drain duct before filling the tank. Turning knob for
draining of the tank into horizontal position (see section 4.7).
Fill the cleaning tank with a sufficient quantity of a suitable
cleaning liquid before switch-on.
The optimum filling level is approx. 2/3 of the tank volume.
The marked maximum filling level of the tank (not available on
S 10 / S 10 H) indicates the recommended filling level with
cleaning items in the bath (see also section 4 Illustration 4.4).
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.
We recommend the use of the cleaning agents listed in section
8.3.
Risk of splashing fluid when switching on the ultrasound!
There is a risk of splashing fluid when a unit filled with fluid is
switched on.
This means that drops of fluid may spray out of the tank.
Please take this into account when using corrosive or other
dangerous cleaning agents.
Move away from the unit and wear the appropriate protective
equipment as specified in the safety data sheet for the cleaning
agent in use.
Flammable products are generally not allowed for use in an
ultrasonic bath. Observe the safety warnings given in section
8.1.
Risk of fire and explosion!
Never use flammable liquids or solvents directly in an ultrasonic
cleaning bath.
Use the cleaning chemicals listed in section 8.3.
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 section
8.1.
Risk of damage to the transducer 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.
Use the cleaning chemicals listed in section 8.3.
