Safety

10 / 46 1756-003 en/2023-07
2.5 Harmful to health due to ultrasound noise
The ultrasound noise typical of the process can be perceived as very unpleasant.
Remaining within a radius of 5 m for an extended period of time may cause damage to health.
• Wear suitable hearing protection.
• Use the lid for noise reduction.
2.6 Hazards due to high temperatures
The device, the sonication fluid and the sonication objects can become hot during operation.
Contact with these products may cause burns. The temperature can be set at up to 75°C.
Ultrasound energy warms up the sonication fluid even without additional heating.
Prolonged ultrasound operation can lead to very high temperatures.
In a device with heating, the set temperature can be significantly exceeded
by the energy of the ultrasound.
• Observe the treatment times recommended by the manufacturer of the ultrasound agent.
Do not leave the ultrasound switched on for longer than necessary.
• Do not reach into the sonication fluid with your hand. Remove sonication objects
with the insert basket or forceps.
• Allow the sonication objects to cool before touching them.
• When lifting from the handles, the hands may touch the edge of the tank
which could be very hot.
In the case of high-boiling liquids, the bath temperature can rise to over 120 °C
due to the energy input of the ultrasound. This can lead to fires and severe burns.
• Do not use combustible, explosive, non-aqueous fluids (e.g. petrol, solvents)
or mixtures with combustible liquids (e.g. alcoholic solutions) directly in the stainless
steel oscillating tank.
2.7 Danger due to ultrasound
The strong ultrasound in the device destroys cell structures. If part of the body is immersed
in the sonication fluid during operation, this can cause damage to skin and also damage
to internal tissue. The periosteum of finger bones can be damaged.
• Do not reach into the sonication fluid during operation.
• Never sonicate living creatures.
Safety

1756-003 en/2023-07 11 / 46
2.8 Danger from agents used
Agents used in the device can be toxic or caustic. They can irritate the eyes,
skin and mucous membranes. The vapours and aerosols can also be dangerous.
• Wear gloves and safety goggles when handling hazardous agents.
• Do not ingest the agents and do not allow them to come into contact
with the eyes or skin. Do not lean over the device, in order to avoid vapours
from coming into contact with the eyes or from being inhaled.
• Close the lid when operating the device. Use an extraction system
if there are dangerous vapours.
• Observe the information on the label and in the safety data sheet for the agent.
• Keep the agents away from children and untrained persons.
2.9 Disposal of sonication fluid
Dispose of the sonication fluid in accordance with the specifications of the manufacturer
of the ultrasound agent used. The recommended ultrasound agents in the TICKOPUR
product line by DR. H. STAMM GmbH are biodegradable in accordance with the provisions
of Regulation (EC) No. 648/2004 (Detergents Regulation). If necessary, the sonication fluid
must be neutralised before disposal.
Depending on the type of contamination involved, water-polluting substances like oils
or heavy metal compounds may be introduced to the sonication liquid during cleaning.
If the threshold values for these substances are exceeded, the sonication liquid must be
processed or disposed of as special waste.
Observe local waste water regulations.

3.5 Function
Ultrasonic system for cleaning using CNp procedure. Double tank version, each with a
cleaning tank and rinsing tank. Ultrasonic transducers at the bottom of the tanks generate
cavitation in the aqueous solution. The additional use of negative pressure in the cleaning
bath leads to the generation of bubbles, which amplify the cleaning effect of the ultrasound.
The SONOREX CNp 28-2 transfers the outstanding cleaning effect of the CNp process
into a compact, mobile cleaning system. The main component of the Plug and Clean system
is the powerful cleaning tank, which is filled with a suitable cleaning solution.
Residue-free rinsing of the cleaned components using the CNp process takes place
in the adjacent, identical rinsing tank, which can be filled with tap water or demineralised
water. Easy-to-use lids with large inspection glasses allow for easy loading and optional
process monitoring during cleaning and rinsing. The size of the two tanks is designed
so that standard 1/1 DIN insert baskets can be easily positioned and components
with a length of up to 570 mm can be cleaned.
3.6 Design and function of the safety device
In the event of a malfunction of the heating control and failure of the fill level sensor,
the attached heating elements must be safely switched off in order to avoid the tank
surface overheating by more than 150°C. To ensure reliable switch-off in the event
of permanent control of the heating elements and evaporation of the bath liquid,
the heating foils are provided with thermal fuses, which interrupt the power supply
to the heating elements from a temperature of 150°C.
