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 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.
