Carefully read the Service Manual before you carry out any
repair works, in particular the Important safety warnings,
section 2.
We assume that the person carrying out the described repair
works is sufficiently educated in the field of safety and
electronics skills. The basic safety instructions are not explicitly
given for each repair work.
We reserve the right to carry out technical modifications on the
units due to advanced development.
Reprints, translations and copying of any kind, even of parts of
the document, are subject to prior written authorization by the
editor.
The copy right remains with the editor.
1.1 How to use the Service Manual
For trouble shooting we recommend to use the table of possible
malfunctions (section 5).
Further useful information on the operation of the unit can be
found in the description of the unit (section 4).
Please observe the important safety warnings (section 2), and
the information on initial operation (section 17).
In case of any further queries Getinge will be glad to assist. For
our technical support and contact address please see the last
page.

1.3 Demands on the service staff
The present Service Manual is intended for authorized service
points and specialized service staff.
Legitimate users of the Service Manual are persons who do not
require to be specifically instructed on the risks caused by
electric equipment.
Special knowledge on electric unit and safety-relevant
knowledge are prerequisite for carrying out any repair works on
ultrasonic cleaning units.
1.4 Testing equipment, tools and measuring instruments
All testing and measuring tools and instruments must be
connected to a grounded socket only.
Apart from the standard electromechanical tools the follwoing
measuring and testing equipment is required for carrying out
the measuring and repair works described in the present
Service Manual:
For electric measuring inside the unit, e.g. resistance and
throughline measuring.
Adjusting range up to approx. 100 Nm. For tests and repair
works which require the opening of the transducer system. After
opening, the transducer system must be screwed with the
correct torque (see section Transducer system). The wrong
torque can cause malfunctions and a breakdown of the unit.
For checking the power consumption of the ultrasonic generator
and the heating.
Power 4 Ampere or more. For the separation of the unit from
the mains and for the safe and controlled upward-adjustment of
the mains voltage.
Certain components on the electronic PCB can be damaged
through electrostatic charges. Therefore, it is absolutely
necessary for the service staff to discharge statically before
they touch the electronic PCB and to remain earthed when
handling the component.
The following items are required for arranging an ESD
protected workplace:
ESD work pad; ESD floor surface; Tools
ESD earthing connection from the wrist of the person to the
work pad; ESD shoes
ESD protective bag; ESD boxes / cartons
Multimeter
Torque wrench
Wattmeter
Adjustable
interrupting
transformer
ESD protective
measures

2 Important safety warnings
Carefully read and observe before inspection and
reoperation of the unit!
The present ultrasonic cleaning unit has been designed for the
treatment of items and liquids only.
Repair and maintenance works which require the unit to be
opened and connected must be carried out by authorized
specialized staff only.
Check the unit and the mains cable for transport damages. In
case of any visible damage do not operate the unit!
Place the unit on a dry and solid surface; ensure that the
workplace is sufficiently ventilated. Keep workplace, unit
housing and operating elements dry. Protect the unit from
entering humidity!
Separate the unit from the mains before you open it.
In order to prevent damages from persons and/or from the unit
all connected electric measuring instruments and the ultrasonic
unit must be connected via an interrupting transformer.
Parts of the ultrasonic generator and the transducer system
carry high-frequency AC voltage during operation.
Due to piezoelectric effects there can be high voltages
produced by exchanging the transducer disks. Earth these
voltages before you touch the transducer disks.
100 –120 V or 220 –240 V
1 phase / 1 N / 1 PE shockproof grounded socket
Fill the cleaning tank with a sufficient quantity of a suitable
cleaning liquid before switch-on. Do not use flammable liquids
directly in the cleaning tank: risk of fire and explosion!
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
the current connected value.
In order to guarantee compliance with the valid safety
regulations and the CE conformity faulty parts must be replaced
by original spare parts only.
The manufacturer cannot be held liable for damages on
persons, on the unit or on the workshop equipment caused by
improper use or wrong repair.

3 Organizational details
3.1 Warranty
The warranty covers all claims based on material and
manufacturing faults. Excluded from the warranty are:
Transport damages; these must be reported to the
forwarding agent immediately upon detection.
Damages caused by improper use of the unit:
e.g. damages on the transducer tank caused by wrong
cleaning media, cleaning items placed directly on the tank
floor, dry running of the unit, etc.
Damages caused by humidity which has entered the unit
from outside.
Unauthorized repair works on the unit.
Improper use and/or operation against the Operating
Instructions.
Wear and tear; example: the transducer tank is a wear part
with regard to the cavitational erosion around the sound-
giving surfaces.
3.2 Warranty period
The limitation period of warranty claims is 2 years (from the
date of purchase). If no proof of purchase can be produced,
Getinge can find out the date of manufacturing by means of the
serial number (nameplate).
Getinge grant a limitation period of 2 years on all exchange
parts and on any repair works carried out.
Please ensure that all documentation concerning the service
works carried out are safely stored.
3.3 Ordering of spare parts
Getinge guarantee the availability of spare parts according to
the valid regulations over a period of 10 years after production
and sale of a unit have stopped. Standard spare parts will be
available for older units.
For your spare parts order we need to know the following data:
Type of unit
Voltage (115 V or 230 V)
Serial number (nameplate)
New units
Repair

3.4 How to find out the year of manufacturing
The year of manufacturing of a unit can be taken from the serial
number indicated on the nameplate.
The serial number is required e.g. for revision purposes, for
spare parts orders and for the determination of the warranty
period.
The first figure (A) –starting from the left –represents the
decade.
The second and third figures (B) –starting from the right –
represent the month.
The first figure (A) –starting from the right –represents the
year.
