2.4 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 Ultrasonic cleaning
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 which
remove dirt particles from surfaces and even from the smallest
grooves and bores.
3.1 Interesting facts on cleaning by ultrasound
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 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. We have a large range of cleaning
media on offer.
In addition, the use of cleaning media is required to reduce the
surface tension of the liquid. This increases the efficiency of the
ultrasonic activity considerably.
The effect of the cleaning medium is improved by the optimised
temperature of the cleaning liquid.
The cleaning period depends on the degree and the kind of
contamination, the cleaning agent used, the set temperature
and the cleaning process.

5.1 Prepare the drain duct
(not on Elmasonic P 30 SE)
On the delivered unit the drain duct is closed off with a plastic
screw cap. For initial operation of the drain duct fix the hose
nozzle delivered with the unit to the drain duct.
1. Unscrew the plastic screw cap anti-clockwise
(see Fig 5.1.1).
2. Screw the hose nozzle (included in delivery) onto the inside
thread of the drain duct (clockwise).
3. Turn the hose nozzle into the required drain position
(see Fig 5.2.2).
The plastic thread is self-sealing when the socket has been
screwed in by hand as far as possible.
Note: Unscrewing the hose nozzle (anti-clockwise) may
cause a leak in the thread connection.
4. The drain duct is now ready for connection to a customer-
provided discharge system. Use a standard hose (dia 1/2”).
Push the hose onto the hose nozzle and fix it with the hose
clamp included in the delivery.

6.1 Filling of the unit
Shut the drain duct before you fill the tank (horizontal position of
the turning knob for draining the tank –see Section 4.7) (not on
Elmasonic P 30 SE).
Fill the cleaning tank with a sufficient quantity of a suitable
cleaning liquid before switch-on.
The recommended optimum filling level is approx. 2/3 of the
tank.
Caution! A filling level below 6 cm may lead to a permanent
loss of heating performance.
The marked maximum filling level indicates the recommended
maximum filling level with immersed cleaning items (see also
Section 4.4. Fig 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 to use the cleaning media 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 cleaning media are generally prohibited for use in
an ultrasonic bath. Please observe the safety warnings in
Section 8.1 (Solvents).
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.
