General 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. We reserve the right to carry out technical modifications on the unit due to advanced development.
Important safety warnings Safety instructions for the use of the unit Intended use The present Elma ultrasonic cleaning unit has been designed for the treatment of items and liquids only. Do not clean any living beings or plants! User Operation of the unit by authorized and instructed staff only.
Ultrasonic cleaning Ultrasonic cleaning 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 piezo- electrical transducer systems and is then transmitted into the bath.
Product description Ultrasonic cleaning process 1. Fill the ultrasonic tank with water and cleaning concentrate (Section 6.1). 2. Heat up the cleaning liquid, if required for the intended cleaning application (Section 6.2). 3. Degas the cleaning liquid – operation in degas mode (Section 6.4).

Initial operation Initial operation Please keep the original packing for possible later service Packing purposes or dispose of it in compliance with the relevant local waste disposal regulations. You can also return the packing to the manufacturer or to your supplier (cost of shipment to be paid by the customer).
Initial operation 4. The drain duct is now ready for connection to a customer- provided discharge system. Use a standard hose (dia 1/2”). Push the hose onto the hose nozzle and fix it with the hose clamp included in the delivery. Fig 5.1.1 Drain duct with blind screw Fig 5.2.2 Drain fitted with hose cap (on delivered unit)
Putting into operation Putting into operation Filling of the unit Shut the drain duct before you fill the tank (horizontal position of Shut the drain duct the turning knob for draining the tank – see Section 4.6). Fill the cleaning tank with a sufficient quantity of a suitable Observe filling level cleaning liquid before switch-on.
Therefore, we recommend not to operate the unit at temperatures exceeding 80° C. For the recommended cleaning temperatures please see the product information on the elma clean chemicals. High temperatures! Risk of burning and scalding! Cleaning liquid, ultrasonic tank, housing, cover, basket and...
Putting into operation Automatic stirring during heating The present unit is equipped with an activatable stirring mode which guarantees a thorough mixing of the cleaning liquid during heating up (only as long as set temperature > actual temperature). Without stirring of the liquid, the generated heat rises to the surface, creating considerable temperature differences within the bath.
Ultrasonic cleaning process Ultrasonic cleaning process Please observe the following instructions before starting the ultrasonic cleaning process. The operator is responsible for the inspection of the cleaning result. Risk of scalding by hot surfaces and cleaning liquid! Ultrasonic energy is physically transformed into heat. CAUTION The unit and the cleaning liquid in the tank heat up during ultrasonic operation even with the heating switched off.
Ultrasonic cleaning process Starting the cleaning process manually Press the on/off key to start the unit. Set the cleaning Set the required cleaning period with the turning knob. period Short period For short period operation set the required cleaning period at operation the turning knob (turn clockwise).
Ultrasonic cleaning process 4. Activate Degas, Sweep or Pulse mode and select ultrasonic frequency and ultrasonic power if required for the intended application. ■ 5. Keep the key ► pressed (> 2 sec.): The unit starts heating up. During the heating-up process the ultrasound is regularly activated to mix the liquid.
Ultrasonic cleaning process Pulse mode Special operating mode to intensify the ultrasonic cleaning effect. Advantageous for the removal of tenacious contaminations. Functioning The ultrasonic effect is increased by 20 % through an increase of the amplitude of the ultrasonic signal. How to proceed ■...
Ultrasonic cleaning process Placement of cleaning items Caution! The ultrasonic bath has been designed for the ultrasonic treatment of items and liquids only. Do not clean living beings or plants! Do not reach inside the tank during ultrasonic operation! Cell walls can be damaged by prolonged exposure to ultrasonic CAUTION activity.
Cleaning media Cleaning media The cleaning chemical to be used must be suitable for the use in an ultrasonic bath to prevent damage to the tank or injuries to the operator. Use the recommended cleaners mentioned in WARNING section 8.3. Observe the restrictions to cleaners containing solvents and aqueous cleaners mentioned in sections 8.1 and 8.2.
