Trouble shooting

Find out if the malfunction is caused by a fault on the unit or by
improper use. Examples for malfunctions due to improper use:
•
The cleaning result is not satisfactory:
The cleaning medium, the cleaning temperature or the
duration of the cleaning cycle are not suitable for the
cleaning task.
The cleaning result can also be impaired by a wrong or
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 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.
