General 1 General The present Operating Instructions are part of the delivered equipment. They must be ready for use at any time and remain with the unit in case of resale. Carefully read the Operating Instructions before using of the unit and operate the electrical appliance according to the instructions. We reserve the right to carry out technical modifications on the unit due to advanced development.
Functioning Exclusion of liability 3 The manufacturer cannot be held liable for damages on persons, equipment or cleaning items caused by improper use. The operator is responsible for the instruction of the operating staff. Functioning Today, cleaning by ultrasound is the most modern fine cleaning method. The electric high-frequency energy created by an ultrasonic generator is transformed into mechanical energy by piezoelectrical transducer systems and is then transmitted into the bath.

Initial operation 5 Initial operation Packing Check for transport damages Placement Please keep the original packing or dispose of it according to the relevant waste disposal regulations. You can also return the packing to the manufacturer free destination (to your account). Check the Elmasonic S for possible transport damages before initial operation. In case of visible damage do not connect the unit to the mains. Contact your supplier and forwarding agent.
Initial operation 4. The drain duct is now ready for connection to a customerprovided discharge system. Use a standard tube (dia 1/2"). Push the tube onto the socket and fix it with the clamp included in the delivery. Illustration 5.1 Drain with plastic screw cap 5.2 Illustration 5.2 Drain fitted with standard tube Connecting the unit to the mains Required mains conditions Earth grounded socket: 1 phase (220-240 or 100-120V); 1 N; 1 PE protective earth.
Putting unit into operation 6 Putting unit into operation 6.1 Filling of the unit Shut the drain Observe filling level Shut the drain duct before filling the tank. (Turning knob for draining of the tank into horizontal position (see section 4.6). Fill the cleaning tank with a sufficient quantity of a suitable cleaning liquid before switch-on. The optimum filling level is approx. 2/3 of the tank volume.
Putting unit into operation The stainless steel tank can be destroyed by crevice corrosion in a very short time. Substances that cause crevice corrosion can be contained in household cleaners. Observe the instructions on limitations of use given in section 8.2. For queries please contact the manufacturer or your supplier. 6.2 Placement of cleaning items Caution! The ultrasonic bath has been designed for the ultrasonic treatment of items and liquids only.
Ultrasonic cleaning process 7 Ultrasonic cleaning process Please observe the following instructions before starting the ultrasonic cleaning process. It is the user’s responsibility to check the cleaning results. Risk of scalding by hot surfaces and cleaning liquid! CAUTION Ultrasonic energy is physically transformed into heat. The unit and the cleaning liquid in the tank heat up during ultrasonic operation even with the heating switched off.
Ultrasonic cleaning process 7.1 Heating up of the cleaning liquid (units with heating) Depending of the degree and kind of contamination and on the cleaning medium used it might be required to heat up the cleaning liquid. For a quick heating-up process and in order to prevent unnecessary energy losses we recommend to use a cover (optional accessory equipment). The ultrasonic energy is transformed physically into heat. Low set temperatures can be exceeded during ultrasonic operation.
Ultrasonic cleaning process 7.2 Temperature-controlled cleaning (units with heating) Functioning How to proceed Elmasonic S units are equipped with an additional temperaturecontrolled cleaning function. The cleaning process is automatically started as soon as the required bath temperature is reached. 1. press the on/off key to start the unit. 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.
Ultrasonic cleaning process 7.4 Starting the cleaning process manually Press the on/off key to start the unit. Select the cleaning period Short period operation Set the required cleaning period with the turning knob. S 10: LED display is off. S 15 – S 900 H: The LED display indicates the set period. For short period operation set the required cleaning period at the turning knob. Press the ►■ key to start the ultrasonic operation. The unit starts the ultrasonic cleaning process. S 10: LED display is on.
Cleaning media 7.6 After the cleaning Follow-up treatment of cleaning items When the cleaning process is finished rinse the cleaning items, e.g. under the tap. Drain the unit Drain the liquid as soon as it is dirty or when the unit is not operated over a prolonged period of time. Certain residues and types of contamination may destroy or damage the stainless steel tank. Use the quick-drain duct to drain the cleaning tank (see section 4.9).
Cleaning media separate vessel (e.g. beaker) with sufficient ventilation; this vessel (beaker) can then be put into the stainless steel tank which is filled with non-flammable liquid (water with a few drops of interlacing agent). 8.2 Limitations on aqueous cleaners Do not use aqueous cleaning media with pH values in the acid range (pH < 7) directly in the ultrasonic tank if fluoride (F¯), chloride (Cl¯) or bromide (Br¯) ions can be taken in by the removed dirt or through the cleaning chemical.
