3.3 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 piezo-

electrical 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.

4.1 Filling of the unit

Fill the cleaning tank with a sufficient quantity of a suitable

cleaning liquid before operation.

Observe filling level

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 (2/3 filling level).

NOTE

Ensure that the chosen cleaning chemical is suitable for

treatment in an ultrasonic bath and observe the instructions on

dosage and compatibility of the material.

We recommend the use of the cleaning agents listed in section

5.1.

Caution! Flammable products are not allowed for use in an

ultrasonic bath. Observe the instructions given in section 5

(cleaning media).

Restrictions concerning further cleaning media are also

indicated in the instructions given in section 5.

For queries please contact the manufacturer or your supplier.

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.

4.2 Cleaning

The items to be cleaned must be covered completely in the

cleaning liquid.

Place the items in the bath with the contaminated side down.

Cleaning instructions

4.3 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.

Use suitable accessories:

Use the plastic cleaning basket for big items.

Suitable for dentures, braces and small items. For cleaning, fill

the beaker with a suitable cleaning chemical.

Insert the loaded dental beaker in the transducer tank which

must be filled with liquid up to approx. 50%. Add a few drops of

a cleaning chemical to the water in the transducer tank.

With the forceps the cleaned items can be taken out of the unit

or items can be held into the liquid for cleaning.

4.4 Start-up of the cleaning process

Do not reach inside the tank during ultrasonic operation!

Cell walls can be damaged by prolonged exposure to ultrasonic

activity.

For taking out the cleaning items switch off the unit or use the

forceps (included in delivery).

NOTE

Press the on/off key in the operating panel of the unit (see also

section 3.7). The unit starts a cleaning cycle which switches off

automatically after 7 minutes.

This process can be repeated as often as required.

After the cleaning process thoroughly rinse the cleaned items in

running water and wipe dry with a cloth.

Press on/off key.

After-treatment o

items: rinsing/drying

Cleaning media

5 Cleaning media

For more efficient cleaning results it is required to add a

suitable cleaning chemical to the liquid in the cleaning bath.

When choosing the cleaning chemical ensure that the product

is suitable for the use in an ultrasonic bath; products that are

not suitable can cause damage to the transducer tank. When

using other chemicals than the ones recommended please

observe the instructions given on the label, in particular

concerning the use in an ultrasonic bath.

Risk of fire and explosion!

Never use flammable liquids or solvents directly in the

ultrasonic cleaning tank.

We recommend to use the cleaning media listed in section 5.1.

CAUTION

Ultrasound increases the vapourisation of liquids and creates

finest vapours which can easily catch fire at ignition sources.

Risk of damage to the transducer tank!

Do not use acid cleaners (pH value below 7) directly in the

stainless-steel tank if the items to be cleaned carry

contaminations containing halogenides (fluorides, chlorides or

bromides).

The same applies to salt solutions (NaCl).

We recommend to use the cleaning media listed in section 5.1.

NOTE

The stainless-steel tank can be destroyed by crevice corrosion

within a very short period. Substances causing crevice

corrosion can be contained in household cleaners.

The manufacturer cannot be held responsible for damages

caused by crevice corrosion.

For queries please contact the manufacturer or your supplier.
