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.

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 Putting unit into operation

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.

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.

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.

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

6.2 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! Cell walls can be damaged by prolonged exposure to ultrasonic

activity. For placing and taking out the cleaning items always switch off

the unit.

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.

6.3 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 the fesh cleaning liquid for approx. 5 - 10 minutes.

7 Ultrasonic cleaning process

Please observe the following instructions before starting the

ultrasonic cleaning process. It is the user’s responsibility to

check the cleaning results.

Risk of scalding by hot surfaces and cleaning liquid! Ultrasonic energy is physically transformed into heat. The unit and the cleaning liquid in the tank heat up during

ultrasonic operation even with the heating switched off. During permanent operation with cover temperatures exceeding 60°C can be reached.

During permanent operation with cover and heating temperatures exceeding 80°C can be reached.

Do not reach inside the bath. If necessary touch unit and basket with protecting gloves!

Ultrasonic units can produce annoying sounds. Wear personal ear protection devices when working close to an

ultrasonic unit which is operated without cover.

Sensitive surfaces can be damaged when exposed to ultrasound over prolonged periods, particularly at low cleaning frequencies.

Ensure that sensitive surfaces are exposed to ultrasonic acitivity for a suitable period only.

If in doubt check the cleaning progress regularly and observe the state of the surface material.

Ultrasonic energy is physically transformed into heat. The unit and the cleaning liquid in the tank heat up during

ultrasonic operation even with the heating switched off. During permanent operation with cover temperatures exceeding 60 °C can be reached.

For the cleaning of temperature-sensitive items please take into consideration the heating-up of the cleaning liquid.

Please observe that the temperature of the cleaning media remains below 42 °C when cleaning parts contaminated with fresh protein or blood.

ATTENTION

Ultrasonic cleaning process

BA_Elmasonic EASY_EN_Vers. 03.2016.

7.1 Heating up of the cleaning liquid (units with heating)

Depending of the degree and kind of contamination and on the cleaning medium used it might be required to heat up the cleaning liquid. For a quick heating-up process and in order to prevent unnecessary energy losses we recommend to use a cover (optional accessory equipment).

The ultrasonic energy is transformed physically into heat. Low set temperatures can be exceeded during ultrasonic operation.

The cleaning effect through ultrasonic cavitation is reduced when cleaning with high temperatures. We recommend not to exceed a temperature of 80°C inside the tank.

For the recommended cleaning temperature please observe the product information of the used elma clean cleaner.

High temperatures! Risk of burning and scalding! Cleaning liquid, cleaning tank, casing, cover, basket and

cleaning items can heat up considerably. Do not reach inside the bath.

If necessary wear protective gloves when touching unit and basket!

Cleaning temperature recommendations in the medical sector: Please observe that the temperature of the cleaning media

remains below 42 °C when cleaning parts contaminated with fresh protein or blood.

Please observe the temperature even when using low or no heating.

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

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.

9.3 Repair

Repair and maintenance works which require the unit to be connected and opened must be carried out by authorised and specialised personnel only.

Risk of electrocution due to live parts inside the unit! Pull the mains plug before opening the unit!

The manufacturer cannot be held responsible for any damage caused by unauthorised maintenance or repair works on the unit.

In the case of a break-down of the unit, please contact the manufacturer or your supplier.
