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. 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. In order to achieve efficient cleaning results the liquid in the cleaning bath must contain a suitable cleaning chemical.

Initial operation

Initial operation Check for transport damages

Check the Elma X-tra for possible transport damages before initial operation. In case of visible damages do not connect the unit to the mains. Contact your supplier and forwarding agent.

Placement

For operation, place the unit on a dry and solid surface. Ensure that the workplace is sufficiently ventilated! Risk of electrocution due to humidity inside the unit! Protect the unit from entering humidity.

DANGER

The unit inside is splashwater-proof. Keep workplace and housing dry in order to prevent electrical accidents and damages on the unit. Ambient conditions

Connect the unit to the mains

4.1 Observe filling level

•

Allowed ambient temperature during operation: +5°C - +40°C

•

Allowed relative humidity of air during operation: max. 80%

•

No condensation

Connect the unit to a correctly grounded shockproof socket only. The mains plug must be connected to an easily accessible socket only, as it serves as interrupted device!

Filling of the unit Fill the cleaning tank with a sufficient quantity of a suitable cleaning liquid before operation. See illustration 4.1

Illustration 4.1 optimum filling level at marking on tank wall

BA_X-tra_EN_Vers.01.2014

Initial operation

Dry running of the transducer tank can cause damage to the unit. Ensure that the cleaning tank is filled to the optimum level during operation (see tank marking). Suitable cleaning agents

Ensure that the chosen cleaning chemical is suitable for treatment in an ultrasonic bath and observe the instructions on dosage and the compatibility of the material. We recommend the use of the cleaning agents listed in section 6.1.

Prohibited cleaning agents

Flammable products are not allowed for use in an ultrasonic bath. Observe the instructions given in section 6 (cleaning media).

Restrictions concerning further cleaning media are also indicated in the instructions given in section 6. For queries please contact the manufacturer or your supplier. Degassing of liquids

Freshly mixed cleaning liquids are saturated with air which lessens the cleaning effect of the ultrasonic activity. By sounding the liquid over a period of several minutes before the cleaning process the tiny air bubbles in the liquid are eliminated. Danger of damage to the transducer system! Fill no liquid > 60°C and < 10°C in the ultrasonic tank.

ATTENTION

BA_X-tra_EN_Vers.01.2014

Cleaning

5.1

Heating up of the cleaning liquid Depending on the degree and kind of contamination and on the cleaning medium used it is recommendable to heat up the cleaning liquid.

Turn switch „heating“ to position „on“

Switch on the heating. The yellow control lamp "heating" is turned on.

Setting of temperature at thermostate

Select the required cleaning temperature. The tank must be filled at least half. The optimum filling level is marked on the tank wall (page 7 - illustration 4.1). In order to achieve a uniform heating of the cleaning liquid it is necessary to switch on the ultrasound from time to time or to stir the liquid. Without stirring of the liquid the heat will rise to the surface. There will be a considerable gradient of temperature within the cleaning tank (the temperature difference between the liquid surface and the bottom of the tank can be as high as 40°C). Also, lime settings will form around the heating element because the high temperature is not fully transmitted to the liquid.

5.2

Placement of cleaning items Caution! Do not place the cleaning items directly on the bottom of the transducer tank as this might lead to damages on the unit. Cleaning basket

Put the cleaning items into the stainless-steel cleaning basket.

BA_X-tra_EN_Vers.01.2014

Cleaning

5.3

Start-up of the cleaning process Do not reach inside the tank during ultrasonic operation! CAUTION

Cell walls can be damaged by prolonged exposure to ultrasonic activity. For taking out the cleaning items always switch off the unit.

Switch on timer

Set the timer to the required cleaning period: timer operating mode or permanent operating mode.

Timer operating mode

For short operating periods set the timer to timer operating mode (1-15 min). The unit starts the ultrasonic cleaning process and automatically switches off after the set period. This process can be repeated as often as necessary.

Permanent operating mode

For longer cleaning cycles switch the timer to the left into permanent operating mode (∞). In this operating mode the unit does not automatically switch off. The ultrasound must be switched off manually after the cleaning process is finished (position "off").

Setting of power

Select the required power according to the intended cleaning intensity:

soft

Gentle cleaning for the removal of light contamination and for the cleaning of sensitive surfaces.

power

Intensive cleaning for tenacious contamination and for the quick cleaning of robust surfaces.

Aftertreatment: rinsing/drying

After the cleaning process thoroughly rinse the cleaned items in running water and dry in a drying unit or wipe with a cloth.

BA_X-tra_EN_Vers.01.2014

Cleaning media

ATTENTION

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 user. Use the recommended cleaners mentioned in section 6.3. Observe the restrictions to cleaners containing solvents and aqueous cleaners mentioned in sections 6.1 and 6.2. For queries please contact the manufacturer or your supplier.

Exclusion of liability
