1.2 Instructions for the use of the unit
The present Elma ultrasonic cleaning unit has been designed
for the treatment of items and liquids only.
No cleaning of living beings or plants!
Operation of the unit by authorized and instructed staff only.
Observe the instructions given in the manual.
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 the case
of suspected humidity inside the unit or in the case of
malfunctions and after operation, unplug the mains plug.
The unit must only be opened by authorised specialised
personnel.
Fill the unit with a sufficient quantity of cleaning liquid before
switch-on. Flammable liquids must not be treated by ultrasound
directly in the cleaning tank: risk of fire and explosion!
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.
Wear personal ear protection devices when working close to an
ultrasonic unit which is operated without cover.
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 damages on
persons, equipment or cleaning items caused by improper use.
The operator is responsible for the instruction of the operating
staff.
Temperature during storage: +5 C (+41 F) to +40 C (+104 F)
Temperature during transport: -15 C (+5 F) to +60 C (+140 C)
Humidity and air pressure during storage and transport:

2 Intended use
Ultrasonic cleaning machines are exclusively intended for
ultrasonic irradiation of objects and liquids. Thereby, no
flammable liquids are permitted to be used directly in the
cleaning tanks.
The machine is only permitted to be operated by trained
personnel and not by children. Operation and placement must
be performed in accordance with the conditions and media
defined in the operating manual.
The service intervals and regional regulations for checking the
equipment must be complied with.
2.1 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!
2.2 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 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.
