7.2 Temperature-controlled
cleaning
(units with heating)
Elmasonic S units are equipped with an additional temperature-
controlled cleaning function. The cleaning process is
automatically started as soon as the required bath temperature
is reached.
Functioning
1. press the on/off key to start the unit.
How to proceed
2. select the required temperature.
3. set the required ultrasonic cleaning period.
4. keep the start/stop key pressed > 2 sec:
The unit starts heating up.
During the heating-up process the ultrasound is regularly
activated to mix the liquid.
When the set temperature is reached the ultrasound is
switched on for the duration of the set cleaning period.
When the set cleaning period has run down, the ultrasonic
activity switches off automatically. The heating continues
operating at the set temperature.
7.3
Automatic mixing of the liquid during
heating up (units with heating)
Without mixing of the liquid the generated heat will rise to the
surface of the bath. This will cause a strong gradient of
temperature inside the cleaning tank. In order to ensure an
even heating-up of the cleaning liquid, it makes sense to mix
the liquid from time to time, e.g. by means of ultrasound.
Elmasonic S units are equipped with an additional mixing
device which guarantees the optimum mixing of the cleaning
liquid during the heating up process.
The ultrasound is activated for operating periods of approx. 5
seconds each with one-minute breaks in between.
