About this operating manual/1
1 About this operating manual
These instructions for use contain necessary and useful informa-
tion on how to operate the ultrasound bath safely and efficiently.
• Read these instructions for use before using the ultrasound
bath.
• Pay special attention to chapter 2Safety.
• If you pass this ultrasound bath on to others, please enclose
these instructions for use.
• Contact your specialist dealer or BANDELIN if any of your ques-
tions are not answered in these instructions for use. Information
on service can be found in chapter 6.4Repair.
Illustrations are provided as examples and are not to scale.

2 Safety
2.1 Use of the ultrasound bath
The following applications are possible with the ultrasound bath:
• Ultrasonic cleaning of objects of various shapes, types and sizes,
• Homogenising, emulsifying,
• Rapid degassing of liquids,
• Sonochemical applications, e.g. for radical production or
improved material transport,
• Sample preparation for analysis.
A solution of water and a special ultrasound preparation is used as
the sonication fluid. Information on the sonication fluid can be
found in chapter 5.2Sonication fluid.
Objects to be treated may not be placed on the bottom of the oscil-
lating tank. They must be placed in the sonication fluid in an insert
basket or another suitable container. An overview of suitable
accessories can be found in chapter 10Accessories.
In the case of stains, discolouration, rust, etc., a deep cleaning can
be performed using special detergents and indirect sonication.
Do not operate the ultrasound bath while unattended.
2.2 To be used in the medical sector
The medical purpose of the ultrasound bath is to clean instruments.
Ultrasonic cleaning takes place in the context of further steps
needed for the reprocessing of medical ultrasound baths. In doing
so, observe the hygiene requirements according to the applicable
regulations. The ultrasound bath is a Class I medical ultrasound
bath pursuant to Regulation (EU) 2017/745.
EMDN nomenclature: V0799
Indications/areas of application
Medical instruments can be cleaned in the ultrasound bath as part
of manual processing, and before or after automated reprocessing.

1686-001 en/2022-05 7/52
Safety/2
The information supplied by the instrument manufacturer specifies
whether the instruments are suited for ultrasonic cleaning.
Contraindications/exclusions
• Lenses, camera systems, light cables, mirrors, or objects made
of or containing elastic materials (e.g. catheters, respiratory sys-
tem functional parts, flexible endoscopes) are not suitable for
sonication, or are only suitable under certain conditions. The
specifications of the respective manufacturer provide informa-
tion on suitability for ultrasonic cleaning.
• The ultrasound bath is not suitable for cleaning or disinfecting
contact lenses.
• The direct sonication of flammable liquids is not permitted.
Possible side effects/restrictions
• Ultrasound does not disinfect. However, processes such as
chemical disinfection may be accelerated in the ultrasound bath.
• Cavitation erosion can cause surfaces to be mechanically cor-
roded and their coatings to dissolve.
User group
The ultrasound bath may be used by persons who have been quali-
fied and trained for their work, e.g. the reprocessing of instruments.
Pregnancy is not a contraindication for using the ultrasound bath.
Serious incidents must be reported to
BANDELIN electronic GmbH & Co. KG and to the competent author-
ities.

2/Safety
8/52 1686-001 en/2022-05
2.3 Prevention of cross-contamination and infec-
tion
If the ultrasound bath is used in the medical field, regularly clean
and disinfect the surfaces of the device with a surface disinfectant
that has at least bactericidal, yeasticidal and limited virucidal prop-
erties, in order to avoid cross-contamination. Process accessories
such as holders, carriers or baskets in a cleaning and disinfection
device.
At higher temperatures, vapours and aerosols that are contami-
nated with introduced impurities may escape from the ultrasound
bath. This can lead to infections and disease. When cleaning medi-
cal instruments, avoid bath temperatures above 40 °C. If neces-
sary, use a lid, suction device or protective equipment.
2.4 Keep out of reach of children
Children cannot identify hazards posed by the ultrasound bath.
Therefore, keep the ultrasound bath out of the reach of children.
2.5 Danger of electric shock
The ultrasound bath is an electrical device. Failure to follow safety
rules can result in a life-threatening electric shock.
• Protect the ultrasound bath from moisture and wetness. Keep
the surface and controls clean and dry.
• Only transport the ultrasound bath in empty condition.
• Only drain the ultrasound bath when it is switched off.
• Do not spray or expose the ultrasound bath to splashing water.
• Always disconnect the ultrasound bath from the mains before
cleaning or maintenance.
• Only connect the ultrasound bath to a power outlet with a
grounded socket.
• If you notice a defect in the ultrasound bath, disconnect the
mains plug immediately. Do not connect a defective ultrasound
bath to the mains.

1686-001 en/2022-05 9/52
Safety/2
• Repairs should only be carried out by the manufacturer. See
chapter 6.4Repair.
• Position the ultrasound bath so that it is easy to unplug the
mains connection at any time and without difficulty.
2.6 Harmful to health due to ultrasound noise
The ultrasound noise typical of the process can be perceived as
very unpleasant. Remaining within a radius of 2 m for an extended
period of time may cause damage to health.
• Wear suitable hearing protection.
• Use a lid to reduce noise. The ultrasound bath can also be used
in a sound proof box.

2/Safety
10/52 1686-001 en/2022-05
2.7 Hazards due to high temperature
The ultrasound bath, the sonication fluid and the sonication objects
can become hot during operation. Contact with these products may
cause burns. The temperature can be set at up to 80 °C.
Ultrasound energy warms up the sonication fluid even without
additional heating. Prolonged ultrasound operation can lead to very
high temperatures. In an ultrasound bath with heating, the set
temperature can be significantly exceeded by the energy of the
ultrasound.
• Observe the treatment times recommended by the manufac-
turer of the ultrasound preparation. Do not leave the ultrasound
switched on for longer than necessary.
• Do not reach into the sonication fluid with your hand. Remove
sonication objects with the insert basket or forceps.
• Allow the sonication objects to cool before touching them.
• Lifting from the handles can cause the hands to touch the edge
of the oscillating tank, which can be very hot. After operation,
allow the ultrasound bath to cool down before lifting it for emp-
tying.
Non-aqueous fluids can heat up many times faster than water. A
possible flashpoint can be reached or exceeded after a very short
sonication time. In the case of high-boiling liquids, the bath tem-
perature can rise to over 120 °C due to the energy input of the
ultrasound. This can lead to fires and severe burns.
• Do not use combustible, explosive, non-aqueous liquids (e.g.
petrol, solvents) or mixtures with combustible liquids (e.g. alco-
holic solutions) directly in the stainless steel oscillating tank.
• Small quantities of flammable liquids in sample containers can
be sonicated indirectly. Before sonication of flammable liquids,
familiarise yourself with the necessary safety measures and
applicable regulations for handling these liquids.
2.8 Danger due to ultrasound
The strong ultrasound in the ultrasound bath destroys cell struc-
tures. If a body part is immersed in the sonication fluid during oper-
ation, this can lead not just to skin damage, but also to internal
tissue damage. On fingers, the periosteum can become damaged.
