2.5 Information for particular groups of people

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.

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 piezoelectrical 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.

Functioning

BA_Elmasonic EASY_EN_Vers. 03.2018.

Temperature

Cleaning period

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

EASY 10 / EASY 10 H) indicates the recommended filling level with cleaning items in the bath (see also section 4 Illustration 4.5).

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.

Flammable products are generally not allowed for use in an ultrasonic bath. Observe the safety warnings given in

section 8.1.

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.

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 section 8.2. For queries please contact the manufacturer or your supplier.

9 Maintenance

9.1 Maintenance / Care

Pull the mains plug before carrying out any maintenance works!

The present Elmasonic EASY unit is maintenance-free. Check the casing and the mains cable for damage regularly in order to prevent electrical accidents.

Lime deposits on the stainless-steel tank can be cleaned gently e.g. with elma clean 40 or elma clean 115C (operate the unit with concentrate + water).

Check regularly the grid of the air fan at the bottom of the unit (not existent in all units).

Remove dirt if necessary to allow sufficient ventilation inside the unit.

Residues of cleaning media can be wiped away with a household cleaner or decalcifier depending on the kind of contamination. Do not put the unit in or under water!

If the unit is used for medical and sanitary purposes it is necessary to disinfect the transducer tank and the surfaces regularly (standard surface disinfectants).

9.2 Service life of the transducer tank

The transducer tank and particularly the ultrasound transmitting surfaces are wear parts. The changes on the surfaces that occur after a certain operating period are visible first as grey areas and later on as material abrasions, the so-called cavitation erosion.

To prolong the service life of your ultrasonic unit even more we recommend to observe the following instructions:

 Regularly remove any cleaning residues, in particular metal

particles and rust films.

 Use suitable cleaning chemicals, with particular caution

concerning the kind of removed contamination (see instructions section 8.2).

 Abrasive particles from removed contaminations (e.g.

polishing pastes) must be drained and removed from the cleaning tank as frequently as possible (exchange the cleaning bath).

 Exchange the cleaning medium before it is too heavily

contaminated.

 Do not operate the ultrasound unnecessarily; switch off after

the cleaning process.
