Fig. 8:  Cover the ultrasonic cleaning unit with the lid provided. Using the 

lid keeps the cleaning solution at a stable temperature, guaranteeing 

maximum cleaning and/or disinfection efficiency.

7.3.1  USING THE GLASS BEAKERS (OPTIONAL) FOR DETERGENTS NOT 

COMPATIBLE WITH THE STAINLESS STEEL TANK

When using detergents which could damage the stainless steel tank, (see 

paragraph 7.8.1), you must use the special glass beakers and lid for beakers 

(provided on request).

Fig. 9: Fill the cleaning tank without reaching the indentation. The water 

must touch the indentation when the beakers are inserted in the tank. 

Fig. 10:  Pour  the  potentially  corrosive  detergent  solution  into  the  special 

glass beakers and immerse the objects to be cleaned and/or disinfected in 

the beakers.

Fig. 11:  Use the lid for beakers to suspend the beakers in the tank. Immerse 

the beakers in the cleaning solution to at least half their height.

7.4  DEGAS FUNCTION

The degas function reduces the presence of air in the cleaning solution, 

optimising  cleaning  efficiency.    Degassing  is  strongly  recommended 

whenever  you  change  the  cleaning  solution.    Degassing  can  be  done 

automatically or manually. 

The degas and sweep functions cannot be used simultaneously.

7.4.1  AUTOMATIC DEGASSING

The ON/OFF light comes on.

Fig. 13:  Press the START/STOP button (fig. A, 10). 

The START/STOP light comes on.

Fig. 14: Hold the degas button down for at least 2 seconds (fig. A, 12). The 

degas light starts flashing.

Degassing takes place for 10 minutes then goes off automatically.

7.4.2  MANUAL DEGASSING

Fig. 15:  Turn the appliance on by pressing the ON/OFF button (fig. A, 14). 

The ON/OFF light comes on.

Fig. 16: Use the time dial to set the required time. Press the START/STOP 

button (fig. A, 10). The START/STOP light comes on. 

Fig. 17:  Press the degas button (fig. A, 12). The degas light comes on.

Degas the detergent solution when being used for the first time for about 

5-10 minutes.

Fig. 18:  Turn the degas function off by pressing the degas button (fig. A, 12). 

The degas light goes off.

7.5  ULTRASONIC CLEANING

Danger of burns!

While the appliance is in operation, do not touch the detergent 

solution or the ultrasonic conductors.  Touch the appliance and 

basket with protective gloves only!

When cleaning impurities containing traces of blood or protein, 

make sure the temperature remains below 42°C/ 107°F. The 

detergents/disinfectants recommended for use with zeta sonic 

are listed in section 7.7.

7.5.1  AUTOMATIC CLEANING

After  correctly  filling  the  tank  with  the  cleaning  solution,  immerse  the 

instruments to be cleaned/disinfected, close the lid and proceed as follows:

Fig. 19:  Turn the appliance on by pressing the ON/OFF button (fig. A, 14). 

The ON/OFF light comes on.

Fig. 20: Use the temperature dial (A) to set the required temperature. The 

continuous light (B) indicates the set temperature, while the flashing light (C) 

displays the actual temperature of the cleaning solution. As the solution heats 

up, the light moves in the direction of the set temperature.

Fig. 21: Use the time dial (D) to set the required time. The continuous 

light (E) displays the set time, while the flashing light (F) displays the time 

remaining to the end of the cycle.

Fig. 22:  Hold the START/STOP button down for at least 2 seconds (fig. A, 10). 

The START/STOP light (G) starts flashing and comes on steadily when the set 

temperature is reached (fig. 20, B). The appliance starts heating the cleaning 

solution.

During heating, ultrasound mixing of the cleaning solution is 

activated  automatically  (active  for  five  seconds  at  one  minute 

intervals  during  heating).    The  ultrasound  mixing  is  only 

activated when the actual temperature is less than the set 

temperature.

Fig. 3:  Connect the threaded connector to the transparent hose (fig. C, 17) 

and fasten with the hose clip provided (fig. C, 18).

The device drains through gravity. Place the drain hose at the same height 

as, or below, the surface on which the appliance is resting and avoid upward 

curves.

Fig. 4: Insert the main power socket into the appropriate outlet at the rear 

of the device (fig.A, 6) and subsequently connect the plug to the mains. 

In this regard, strictly follow the indications described in paragraph 6.4.

Failure  to  comply  with  any  of  the  above-stated  equipment 

installation regulations can lead to equipment malfunctioning 

and render the warranty null and void.

6.6  DECLARED USE

The zeta sonic appliance is designed for the rapid in-depth cleaning and/or 

disinfection of dental prostheses and dental and surgical instruments made 

from metal, glass, ceramic and other material.

6.7   NON-DECLARED/PROHIBITED USE

Using  the  equipment  for  any  purpose  not  considered  in 

paragraph regarding “Declared use” shall be considered 

improper and thus forbidden. 

The improper use of the equipment renders the warranty null 

and void and Zhermack declines all liability for any damage to 

objects and injury to operators or third parties.

The main reasons for which the warranty is rendered null and void are given 

in paragraph 2.2 and in the “Warranty Certificate” attached to this Manual.

CHAPTER 7: USING THE EQUIPMENT

7.1  GENERAL WARNINGS

•  For  total  certainty  of  safe  operation,  scrupulously  follow  the 

work phases given below.

•  Use only products suitable for ultrasonic treatment.

•  Never pour very hot liquids into the cold ultrasonic tank.

•  Always use personal protection devices (e.g. gloves, goggles 

and mask). 

•  Always operate the appliance with the lid closed.

•  Do  not  overload  the  appliance  with  instruments  and  make 

sure they are covered with cleaning solution.

•  Never  go  below  the  minimum  level  and  never  exceed  the 

maximum filling level indicated (fig. 6).

•  Do  not  pour  water  on  live  electrical  parts  to  avoid  residual 

risks (see paragraph 7.8).

Do not use the appliance without the cleaning solution in the 

tank.

7.2 USE

The principal steps for correct use of the ultrasonic cleaning unit are as 

follows:

•  fill  with  cleaning  solution  and  insert  the  objects  to  be  cleaned  and/or 

disinfected;

•  degas the cleaning solution (optional but recommended);

•  close  the  lid  and  perform  the  ultrasonic  cleaning  (possibly  using  the 

sweep function for optimum efficiency).

7.3  ADDING THE CLEANING SOLUTION AND OBJECTS TO BE CLEANED 

AND/OR DISINFECTED 

Fig. 5: Before filling the ultrasonic cleaning unit, make sure the drainage 

knob is closed.

Fig. 6: Prepare the cleaning solution using the quantities of detergent/

disinfectant specified in the manufacturer’s instructions. For optimum 

disinfection and cleaning of instruments, we recommend using zeta 1 ultra 

Zhermack®.

Fill the tank with about 2 litres of cleaning solution. The indentation in the 

tank indicates the maximum recommended filling level which must never 

be exceeded, even after the objects to be cleaned and/or disinfected have 

been inserted.

Fig. 7:  Place the objects to be treated in the stainless steel basket. Immerse 

the basket in the ultrasonic cleaning unit. The objects must be immersed 2-3 

cm below the level of the cleaning solution. 

To avoid damage to the appliance:

•  never place objects directly on the bottom of the tank;

•  do not overload the instrument basket.
