2.2 Safety instructions for the use of the unit
The present Elma ultrasonic cleaning unit has been designed
for the treatment of items and liquids only. Do not clean any
living beings or plants!
Operation of the unit by authorized and instructed staff only.
Observe the instructions given in the manual. Children are not
allowed to 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.
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.
The unit must be opened by authorised specialised personnel
only.
Risk of fire and explosion! Do not fill flammable liquids into the
cleaning tank.
Risk of burning and scalding! Depending on the operational
period of the unit, unit surfaces, cleaning liquid, basket and
cleaning items can heat up considerably.
Ultrasonic units can produce annoying sounds. We recommend
to operate the unit with the suitable cover (accessory
equipment) to reduce the noise level.
Wear personal ear protection devices when working close to an
ultrasonic unit which is operated without cover. A special noise
production box is available for units up to Elmasonic P 120 H.
Do not reach inside the cleaning liquid or touch sound-carrying
parts (tank, basket, cleaning items, etc.) during operation.
The manufacturer cannot be held liable for any damages on
persons, equipment or cleaning items caused by improper use
against the instructions given in the present manual.
The operator is responsible for the correct instruction of the
operating staff.
Temperature during storage:
+5 C (+41 F) to +40 C (+104 F)
Temperature during transport:

Elmasonic P
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.
2.3 Safety instructions on the machine
Observe operating instructions!
Observe warnings and safety instructions given in the operating
manual!
This symbol warns about the risk of injury from hot surfaces and
liquids.
The unit cannot be disposed with household waste! Observe
regional waste regulations!
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.

3.2 Ultrasonic cleaning process
1. Fill the ultrasonic tank with water and cleaning concentrate
(Section 6.1).
2. Heat up the cleaning liquid, if required for the intended
cleaning application (Section 6.2).
3. Degas the cleaning liquid –operation in degas mode
(Section 6.4).
4. Select the required ultrasonic frequency depending on the
cleaning task - 37 or 80 kHz (Section 7.6).
5. Activate the ultrasonic Sweep mode –if required for the
intended cleaning application, e.g. for large cleaning items
(Section 7.4.).
6. Activate the ultrasonic Pulse mode –if required for the
intended cleaning application, e.g. for coarse
contaminations (Section 7.5).
7. Switch on the ultrasound (manual or automatic start-up)
(Section 7.1 and Section 7.2).
8. Put the cleaning items into the cleaning bath (Section 7.8).
9. Rinse the cleaned items if necessary.
10. Dry the cleaned and rinsed items if necessary.
