Once the set temperature has been reached, the ultrasonic treatment
begins for the set cleaning time. At the end of cleaning, the ultrasonic
treatment stops automatically. The heating continues to function at the
temperature set.

7.5.2 MANUAL 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. 23: Turn the appliance on by pressing the ON/OFF button (fig. A, 14).
The ON/OFF light comes on.
Fig. 24: 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.
Wait for the nominal temperature to be reached (the flashing light goes off ).
Fig. 25: 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. 26: Press the START/STOP button (fig. A, 7). The START/STOP light comes
on. The appliance begins ultrasonic cleaning. At the end of the set time, the
ultrasonic treatment stops automatically. The heating continues to function at
the set temperature.
Fig. 27: To stop the ultrasonic treatment before the end of the cycle, press
the START/STOP button (fig. A, 7). The START/STOP light goes off.
7.5.2.1 MANUAL CLEANING AND CONTINUOUS OPERATION
Fig. 28: For long cleaning cycles, turn the dial clockwise to the continuous
operation position (∞). In this position, the ultrasonic treatment does not stop
automatically. The user must stop the ultrasonic treatment manually when
the cleaning process is over by pressing the START/STOP button (fig. 27).
To bring the values back to the "0" position, turn the time and
temperature dial anticlockwise only.
Zeta sonic is fitted with a safety shut-off device to avoid
accidental continuous operation. After 12 hours of continuous
operation, the appliance goes off automatically. To use the
appliance immediately after, the ultrasonic cleaning unit must
be turned on again and the time and temperature must be
reprogrammed.
7.5.3 SWEEP FUNCTION
Zeta sonic has a sweep function which optimises distribution of the
ultrasound waves in the cleaning solution, improving the cleaning results.
Fig. 29: Press the sweep button (fig. A, 8) to start the sweep function. The
light comes on. Press the button again (the light goes off ).
The degas and sweep functions cannot be used simultaneously.
7.6 END OF THE CLEANING CYCLE
Fig. 30: When cleaning is complete, remove the basket containing the
cleaned objects and place it on the inside of the lid (G). Drain the residual
cleaning solution and leave the instruments to dry. If necessary, rinse the
instruments under running water. Inspect the results of the cleaning and if
necessary repeat.
You are recommended to rinse the lid with running water at the
end of each cleaning cycle to prevent the disinfectant from
accumulating and possibly damaging the plastic.
Fig. 31: If the solution is dirty or the appliance is not used for a long time,
empty the liquid from the appliance by turning the drainage knob.
Drain the cleaning solution in respect of the regulations in force
in your country.
• Replacing the cleaning solution frequently prevents the tank
being scratched by residual dirt.
• If using the ultrasonic cleaning unit at T> 60C°/140F° wait for
the cleaning solution to cool down before emptying the tank.
7.7 RECOMMENDED DISINFECTANTS AND DETERGENTS
When choosing the detergent/disinfectant, make sure it is
suitable for ultrasonic treatment and compatible with the
material. Incompatible solution may damage the stainless steel
tank or even cause serious injury to those handling the appliance.
Always respect the quantities indicated by the manufacturers' .
The reference figures can be found on pages 3, 4, 5, 6 and 7 of this manual and in the Quick Guide.

To disinfect and clean generic, surgical and rotary instruments, including the
most delicate, we recommend using zeta 1 ultra Zhermack® (concentrated
without anti-corrosive aldehydes):
Fig. 32: Measure a quantity of 10 ml (=1%) per litre of water, using the
graduated reservoir on the bottle.
Immerse the instruments in the ultrasonic cleaning unit for 15 minutes at
a temperature of 35°C / 95°F to obtain the complete spectrum of action.
Remove the instruments from the ultrasonic cleaning unit and rinse
thoroughly with running water before sterilisation or subsequent use.
To clean and remove alginate residues from all types of impression tray
and instrument, we recommend using algitray Zhermack® (neutral pH,
phosphate-free detergent, concentrated powder or ready-to-use liquid).
Use in the glass beaker:
Fig. 33: Measure 50g (= 2 measures) of algitray powder into a beaker
containing 500ml of water, or pour into the beaker the quantity of algitray
liquid necessary to completely cover the objects to be cleaned.
Immerse the instruments in the beaker, then place the beaker in the
ultrasonic cleaning unit for 10-30 minutes at a temperature of 40°C / 104°F.
Remove the instruments from the ultrasonic cleaning unit and rinse
thoroughly with running water before sterilisation or subsequent use.
To clean and remove residues of stone and stone investment from all
types of impression tray, resin prosthesis and instrument, we recommend
using gipstray Zhermack® (neutral pH, phosphate-free ready-to-use liquid
detergent). Use in the glass beaker:
Fig. 34: Pour into the beaker the quantity of gipstray liquid necessary to
completely cover the objects to be cleaned.
Immerse the instruments in the beaker, then place the beaker in the
ultrasonic cleaning unit for 30-60 minutes at a temperature of 40°C / 104°F.
Remove the instruments from the ultrasonic cleaning unit and rinse
thoroughly with running water before sterilisation or subsequent use.
7.8 RESIDUAL RISKS
Residual risks are:
• a danger that cannot be totally eliminated through design and the
application of safety devices;
• a potential danger that cannot be highlighted.
In order to prevent accidents, always operate with respect to
that described in this Manual. If in doubt, always contact the
Manufacturer or Authorised After-Sales Centre.

7.8.1 RESIDUAL RISK ZONES

All operators should be aware of the residual risks present in this appliance
in order to avoid possible accidents.
Dangers deriving from noise emission:
In certain conditions, ultrasound appliances may represent a temporary
acoustic disturbance. In proximity to an ultrasound appliance operating
without a lid, you should wear ear protectors.
Dangers deriving from hot surfaces:
Danger of burns! The ultrasound energy is transformed into heat. According
to the length of time the appliance is in operation, the surfaces of the
appliance itself, the cleaning solution, the instrument basket and the material
to be cleaned may overheat. If you need to move the ultrasonic appliance, use
the special handles. Wear special gloves while using the appliance.
Danger deriving from ultrasound transmission by contact:
While the appliance is in operation, you should not touch the cleaning
solution or parts transmitting ultrasound waves (tank, basket). Wear special
gloves while using the appliance.
Dangers deriving from the cleaning solution:
• danger of fire and explosion! Flammable liquids or solvents may not be
used in the ultrasonic cleaning unit;
• danger of damage to the oscillating tank! Avoid direct contact between
the stainless tank and:
- solutions containing hydrochloric acid, sulphuric acid, hydrofluoric acid
or nitric acid;
- acid aqueous solutions (pH < 7) with simultaneous introduction of
halides (fluorides, chlorides or bromides) coming from the detergent
solution or the contaminated objects;
- solutions containing sodium chloride (NaCl);
- household detergents;
- strongly oxidising solutions (e.g. hypochlorites and peracetic acid);
- solutions used to remove stone and cement.
All these limitations on use of the ultrasonic tank also apply if the chemical
substances listed above are contained in the dirt to be removed or as
intrusions in the aqueous liquid.
• To avoid damage to the tank, the solutions listed above may
be used exclusively in the special beakers provided on request
(see paragraph 7.3.1).
• Always precisely respect the specified quantities and follow
the safety instructions provided by the manufacturers of the
chemicals (e.g. use of goggles, protective gloves).
