Functioning

Information for particular groups of people Pregnant woman

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 People with active European EMC and Low Voltage Directive and adhere to the implants 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

3

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:

Mechanical energy

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.

Cleaning media

Elmasonic S

For saponification and removal of the dirt particles a suitable cleaning agent is required. Elma has a large range of cleaning media on offer.

7

Product description

Elma Schmidbauer GmbH

Cleaning chemicals are also necessary to reduce the surface tension. This increases considerably the efficiency of the ultrasonic activity. Temperature

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.

Cleaning period

The cleaning period depends on the degree and the kind of contamination and on the correct selection of ultrasonic energy, cleaning agent and temperature.

Filling of the unit Shut the drain

Observe filling level

Suitable cleaning agents

WARNING

Prohibited cleaning agents

DANGER

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 Elmasonic 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.

CAUTION

18

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.

Elmasonic S

Elma Schmidbauer GmbH

Putting unit into operation

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.

CAUTION

6.2

Danger of damage to the transducer system! Fill no liquid > 60 °C and < 10 °C in the ultrasonic tank.

Placement of cleaning items Caution! The ultrasonic bath has been designed for the ultrasonic treatment of items and liquids only. Do not clean-living beings or plants! Do not reach inside the tank during ultrasonic operation! CAUTION

Cell walls can be damaged by prolonged exposure to ultrasonic activity. For placing and taking out the cleaning items always switch off the unit.

No cleaning items on the bottom of the tank Use cleaning basket Acid tank

6.3

Do not place the cleaning items directly onto the bottom of the cleaning tank, as this might lead to damages to the unit. Place the cleaning items into the stainless steel cleaning basket (accessory equipment). For the use of cleaning chemicals which might destroy or damage the stainless steel tank use a separate container. For the special plastic cleaner tank for acid chemicals please contact your supplier.

Degassing of liquid Freshly mixed cleaning liquids are saturated with air which lessens the cleaning effect of the ultrasonic activity. By sonification of the liquid over a period of several minutes before the cleaning process the tiny air bubbles in the liquid are eliminated. Degas key

Degas the fesh cleaning liquid for approx. 5 - 10 minutes. For switch-on and switch-off press the degas key.

Auto degas

The Elmasonic S units are equipped with an Auto-Degas option. When the programmed period has finished, the Degas function is automatically switched off (10 min).

How to proceed

See chart 4.10. Degas and Sweep functions cannot be operated at the same time.
