Fill the tank
2. The process of adding cleaning agents is explained in chapter Dosing cleaning agent [} 16].
3. Fresh liquid must be degassed approx. 10 minutes prior to ultrasonic cleaning. See Degassing the
liquid [} 16].
IMPORTANT It is important to degas freshly inserted ultrasonic cleaning baths to remove any air
bubbles and dissolved gases that may be present in the cleaning liquid. Failure to remove these
gases negatively impacts the cleaning result.
ðThe tank has been filled.
Insert a basket:
1. Hang the basket filled with the items to be cleaned in the tank.
IMPORTANT The fill level in the tank will increase once the basket or insert is placed inside. This
may cause the tank to overflow in the case of full baskets or dosages > 5%. To avoid this, do not fill
the tank right up to the fill level marking in such cases and fill the remaining space once the basket
has already been inserted.
2. IMPORTANT The objects being cleaned must be completely submerged in the fluid to achieve
good cleaning results. If necessary, reduce the number of objects being cleaned.
è The tank is full, cleaning agent has been dosed (if necessary), liquid has been degassed and the
basket has been inserted. Ultrasonic cleaning can be started.
10.1 Dosing cleaning agent
Cleaning power can be improved by adding aqueous cleaning agents.
WARNING! Please follow the safety instructions and instructions for use and observe the
mixing ratio for the cleaning agent used!
Dosing information for the different unit sizes and typical volume concentrations are shown in the follow-
ing table.
Unit size
Volume concentration in %
Easyclean TEC 30H
ü The aqueous cleaning agent is chosen based on the type of cleaning desired.
WARNING! Do not use flammable cleaning agents! See Use of cleaning agents [} 8].
ü The unit is filled with liquid (e.g. water) up to the recommended tank operating capacity. See Fill the
tank [} 15].
1. Find the dosing quantity for the required concentration in the table and add the liquid to the unit.
2. Stir the cleaning liquid to mix. Stirring is also achieved by degassing the cleaning liquid. See
Degassing the liquid [} 16].
è The cleaning agent is dosed into the liquid. For further steps, see Fill the tank [} 15].
10.2 Degassing the liquid
Degassing of the liquid results in the following advantageous ultrasound effects:
• Improves the cleaning effect of the ultrasound.
• Stabilises the cleaning process.
• Ensures optimal mixing of the cleaning liquid.
• Improves the spatial temperature distribution in the liquid.
