6.1 Filling with cleaning liquid
Risk of damage to the ultrasonic tank!
!
Do not use acidic cleaning agents (pH value below 7) directly in the stainless-steel tank if at the same time halides (fluorides, chlorides or bromides) will be
Notice
introduced from the dirt on the items being cleaned or from the cleaning liquid. The same applies to saline solutions (NaCl).
Use the cleaning liquids listed in chapter 7.3.
The stainless-steel tank can be destroyed within a short time by pitting corrosion. Such substances may also be contained in household cleaners.

Observe the information on further restrictions in chapter 7.2. If in doubt, contact the manufacturer or supplier.
6.2 Heating up cleaning liquid
Depending on the soiling and in order to support the cleaning effect, you may wish to heat up the cleaning liquid.
For quicker heating and avoidance of energy losses, we recommend using the unit cover.
To speed up heating even further, the ultrasound can additionally be activated.
The ultrasonic energy is converted physically into heat. Low preset temperatures can therefore be exceeded in ultrasound operation. In order to ensure
that the temperature in combination with the introduced ultrasonic energy does not accidentally exceed the desired temperature, do not preset the
temperature to a higher value than what is absolutely needed for the cleaning process.
High temperatures! Risk of burns and scalding!
The bath liquid, ultrasonic tank, housing, cover, basket and the items being cleaned can become very hot, depending on the temperature of the liquid.
Do not reach into the bath!
Caution
Wear gloves, if necessary, when touching the unit and the basket.

6.2 Heating up cleaning liquid
Procedure
1. Switch on the On/off switch (Fig. 4.10.1); the blue LED on the control panel lights up
2. Turn the temperature control to set the desired cleaning temperature (Fig. 4.10.1). The heating process starts; when the yellow
LED goes out, the desired cleaning temperature has been reached. Once the preset temperature has been reached, the heating is turned off automatically
via the thermostat.
The ultrasonic energy can heat up the cleaning liquid to a hotter temperature than the preset temperature. In particular, preset
temperatures in the lower range (e.g. 30°C or 40°C) can easily be exceeded.
6.3 Degassing cleaning liquid
Newly prepared cleaning liquid is saturated with air which hinders the cleaning effect of the ultrasound. These microscopic air inclusions can be eliminated
from the liquid by exposing the liquid to ultrasound for several minutes before the cleaning process.
Procedure
1. Use the Time switch (1min. to ∞-min.)(Fig. 4.10.1) to switch on the ultrasound. Set the Function switch
to Degas.
2. Use the Frequency switch (Fig. 4.10.1) to select the frequency 28 kHz. After approx. 5 to 10 minutes, the cleaning liquid has been degassed.
This process can also be performed while heating up the ultrasonic bath.
