Important safety warnings

Read before initial operation!

Intended use User
Mains connection
Prevention of electrical accidents
Cleaning liquid

The present Elma ultrasonic cleaning unit has been designed for the treatment of items and liquids only.
No cleaning of living beings or plants!
The unit must be operated by instructed staff. Do not let children operate the unit.
For safety reasons, the present unit must be connected to a correctly grounded socket only. The technical details indicated on the nameplate must correspond with the available mains connection details, in particular those of the mains voltage and current connected value.
The unit must be opened by authorised specialised personnel only.
For purposes of maintenance and care of the unit, in case of suspected humidity inside the unit or in case of malfunctions and after operation pull the mains plug.

Functioning

Exclusion of liability

The manufacturer cannot be held liable for damages on persons, equipment or cleaning items caused by improper use. The operator is responsible for the instruction of the operating staff.

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

Mechanical energy
Cleaning media Temperature
Cleaning period

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.

Filling of the unit

Shut the drain Observe filling level

Shut the drain duct before filling the tank. (Turning knob for draining of the tank into horizontal position (see section 4.6).
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).

Suitable cleaning agents

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.

Prohibited cleaning Flammable products are generally not allowed for use in an agents ultrasonic bath. Observe the safety warnings given in section 8.1.

Risk of fire and explosion! CAUTION 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!

NOTE

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.

BA/Elmasonic S/GB/0306

15

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.

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!

NOTE

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

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).

Acid tank

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

Degas key Auto degas How to proceed

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. For switch-on and switch-off press the degas key.
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).
See chart 4.9. Degas and sweep functions cannot be operated at the same time.

Ultrasonic cleaning process

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.

CAUTION

High temperatures! Risk of burning and scalding!
Cleaning liquid, cleaning tank, casing, lid, basket and cleaning items can heat up considerably.
Do not reach inside the bath. If necessary wear protective gloves when touching unit and basket!

NOTE

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.

1. press the on/off key to start the unit.
2. select the required temperature.
3. set the required ultrasonic cleaning period.
4. keep the start/stop key pressed > 2 sec: The unit starts heating up. During the heating-up process the ultrasound is regularly activated to mix the liquid. When the set temperature is reached the ultrasound is switched on for the duration of the set cleaning period.
When the set cleaning period has run down, the ultrasonic activity switches off automatically. The heating continues operating at the set temperature.

7.3

Automatic mixing of the liquid during

heating up (units with heating)

Functioning How to proceed

Without mixing of the liquid the generated heat will rise to the surface of the bath. This will cause a strong gradient of temperature inside the cleaning tank. In order to ensure an even heating-up of the cleaning liquid, it makes sense to mix the liquid from time to time, e.g. by means of ultrasound.
Elmasonic S units are equipped with an additional mixing device which guarantees the optimum mixing of the cleaning liquid during the heating up process.
The ultrasound is activated for operating periods of approx. 5 seconds each with one-minute breaks in between.
1. press the on/off key to start the unit.

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 interlacing agent).

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 (F¯), chloride (Cl¯) or bromide (Br¯) ions can be taken in by the removed dirt or through the cleaning chemical. These can destroy the stainless-steel tank by crevice corrosion within a very short period of ultrasonic operation.

Acids and alkaline solutions
Entrainment of chemical substances

Other media which can destroy the stainless-steel tanks when used in high concentrations or with high temperatures during ultrasonic operation are: nitric acid, sulphuric acid, formic acid, hydrofluoric acid (even diluted). (Completeness of list not guaranteed.)
Risk of damage to the unit: do not use cleaning solutions containing more than 0.5 mass % alkali (KOH and/or NaOH) in an ultrasonic cleaning tank.
The above limitations for the use of chemicals in an ultrasonic bath also apply for the aforementioned chemicals when these are brought into an aqueous (particularly distilled water) bath through entrainment or from the removed dirt.

Acid-resistant tank For the ultrasonic treatment with the above mentioned media use an acid-resistant tank (available as accessory equipment).

Disinfectants The limitations of use also apply to the standard cleaners and disinfectants if these contain the above mentioned compounds.

Safety regulations Observe the safety warnings indicated by the manufacturer of the chemicals (e.g. goggles, gloves, R and S phrases).

Maintenance

9.1

Maintenance / Care

Electrical security

Pull the mains plug before carrying out any maintenance works!
The present Elmasonic S unit is maintenance-free. Check the casing and the mains cable for damage regularly in order to prevent electrical accidents.

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

Grid of air fan Care of casing

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!

Disinfection 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.

Elma already uses a highly cavitation-resistant special steel. 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).

· Exchange the cleaning medium before it is too heavily contaminated.

· Do not operate the ultrasound unnecessarily; switch off after

the cleaning process.
