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

insufficient filling level and/or very dirty cleaning liquid.
The unit does not heat up correctly:
For an efficient heating up of the cleaning liquid switch on
the ultrasound (see section 4.5. Start the ultrasound –
temperature-controlled*;with revolution of the cleaning bath)
and use a cover.
Check and find out if the fault is in the heating or in the
ultrasonic system.
Check housing and bottom plate of the unit for any visible
damage and check the tank for leaks before you connect the
unit to an interrupting transformer.
Then connect the unit to an adjustable interrupting transformer
for a functional check. You can easily and safely check the unit
for a short circuit by slowly adjusting the mains voltage upwards
and observing the current consumption. At the same time you
can find out which functions of the unit have broken down.
Various malfunctions are indicated by a flashing LED display:
Getinge Ultrasonic 30 - 300: LED display cleaning period
