6.4 Setting ultrasound frequency
The unit can operate with 2 different ultrasound frequencies.
Use the Frequency switch (Fig. 4.10.1) to set the ultrasound frequency.
The following frequencies are available:
28 kHz For removing rough and stubborn caked-on dirt and for the pre-cleaning of robust surfaces.
80 kHz For fine-cleaning and removing dirt from delicate surfaces.
i
The frequency can be switched during ultrasound operation. (This function is only available in Dura S models.)
6.5 Ultrasonic cleaning operation
Before starting the ultrasonic cleaning process, please observe the following information.
Danger from hot surfaces and cleaning liquid!
The ultrasonic energy is converted physically into heat. The unit and the liquid heat up during ultrasound operation, even if the heating is not switched on.
Caution Temperatures of more than 60 °C can be reached in continuous operation with the cover on. Temperatures of more than 80 °C can be reached in continuous
operation with the cover and the heating on. Do not reach into the bath. Wear gloves, if necessary, when touching the unit and the basket.
!
Ultrasonic units can cause unpleasant hearing sensations under certain circumstances.
Caution Use personal hearing protection when you are in the vicinity of an ultrasonic unit operated without a cover.
Ultrasound can damage delicate surfaces during prolonged exposure, in particular at low cleaning frequencies.
!
In particular for delicate surfaces, make sure to adjust the ultrasonic irradiation time.
Notice If in doubt, check the progress of the cleaning and the condition of the material surface.
