Important safety warnings

2.2

Safety instructions for the use of the unit Intended use

The present ultrasonic cleaning unit has been designed for the treatment of items immersed in a cleaning liquid only. It is not intended for the use in areas with potentially explosive atmosphere.

User

Operation of the unit by authorized and instructed staff only. Observe the instructions given in the manual.

Check for damage

Check unit and mains cable for transport damages. Do not operate the unit in case of visible damages!

Mains connection

For safety reasons, the present unit must be connected to a correctly grounded socket only. The technical details indicated on the nameplate must correspond with the available mains connection details, in particular those of the mains voltage and current connected value.

Mains power supply via main switch

As the units do not have any main switch, they can be supplied with power individually or in groups via a main switch. The units must only be disconnected from the mains power supply when they are in standby mode. If peripheric units from third party providers have to be supplied with power, this must be done using separate switching devices.

Placement

Place the unit on a dry surface. The work area must be sufficiently ventilated to allow any vapours arising from the cleaning liquid to be carried off. Keep work surface, housing and operating elements dry.

Prevention of electrical accidents

For purposes of filling, maintenance and care of the unit, in case of suspected humidity inside the unit or in case of malfunctions and after operation pull the mains plug. The unit must be opened by authorised specialised personnel only.

Cleaning liquid

The unit must be operated with aqueous cleaning media only. Flammable liquids must not be treated by ultrasound directly in the cleaning tank: risk of fire and explosion!

Hot surfaces and liquids

Risk of burning and scalding! Depending on the operational period of the unit, unit surfaces, cleaning liquid, basket and cleaning items can heat up considerably.

Hot steam

During operation with high temperatures inside the cleaning bath open the unit with care: hot steam can emerge when the cover is lifted.

Move unit only when empty

Do not move the filled unit, obstacles may cause the unit to tilt over, or damage the rollers.

Ultrasonic cleaning factors

Noise emission

Ultrasonic units can produce annoying sounds. Wear personal ear protection devices when working close to an ultrasonic unit which is operated without cover. The use of personal ear protection devices is particularly recommended for operating the unit at 25 kHz with open cover.

Sound transmission at physical contact

Do not reach inside the cleaning liquid or touch sound-carrying parts (tank, basket, cleaning items, etc.) during operation.

Functioning

Mechanical energy

Cleaning media

Temperature Cleaning period

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. This process creates millions of tiny vacuum bubbles which implode due to the variations of pressure caused by the ultrasonic activity. Highly energetic liquid jets are created. These jets remove dirt particles from surfaces and even from the smallest grooves and bores. Basically, the cleaning result depends on four factors: Ultrasonic energy is probably the most important mechanical factor in the cleaning process. This energy must be transmitted through a liquid medium to the surfaces which are to be cleaned. The present Elmasonic unit is fitted with the innovative sweep function device: electronic oscillation of the sound field (sweep function) prevents the formation of zones of low performance in the ultrasonic bath. For saponification and removal of the dirt particles a suitable cleaning agent is required. We have a large range of cleaning media on offer. The effect of the cleaning medium is improved by the optimised temperature of the cleaning liquid. The cleaning period depends on the degree and the kind of contamination and on the correct selection of ultrasonic energy, cleaning agent and temperature.

3.2

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 pulse mode at 45 kHz (Section 6.3). 4. Select the cleaning frequency – 25kHz or 45 kHz depending on the intended cleaning application (Section 6.4). 5. Activate the operating mode pulse - if required for the intended cleaning application (Section 6.5). 6. Activate the operating mode dynamic – if required for the intended cleaning application (Section 6.6). 7. Switch on the ultrasound (manual or automatic start-up) (Section 7.1 and Section 7.2). 8. Put the cleaning items into the cleaning bath (Section 7.4. 9. Rinse if necessary (Section 7.5). 10. Dry if necessary (Section 7.5).

Filling of the unit

Pull the mains plug

Caution! For reasons of safety always pull the mains plug for filling the cleaning liquid.

Shut the drain duct Observe filling level

Shut the drain duct before you fill the tank. Fill the cleaning tank with a sufficient quantity of a suitable cleaning liquid before switch-on. Observe the filling level marking inside the tank (see Fig. 4.8.1.F). Fill the tank with aqueous cleaning media only: Ensure that the chosen cleaning agent is suitable for treatment in an ultrasonic bath and observe the instructions on dosage and the compatibility of the material. All flammable cleaning media are prohibited for use in an ultrasonic bath. Please observe the safety warnings in Section 8(Cleaning media).

Allowed and prohibited cleaning agents

Risk of fire and explosion! DANGER

Never use flammable liquids or solvents directly in an ultrasonic cleaning bath. Use the cleaning chemicals listed in Section 8.3. Ultrasonic activity increases the vaporisation of liquids and creates a very fine mist which can catch fire on any ignition source. Observe the instructions on limitations of use given in Section 8.1. Risk of damage to the ultrasonic tank!

ATTENTION

Do not use any acid cleaning agents (pH value < 7) directly in the stainless steel tank if the cleaning items or the contamination of the cleaning items contain halogenides (fluorides, chlorides or bromides). The same applies to NaCl solutions. Use the cleaning chemicals listed in Section 8.3. 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.

ATTENTION
