1.1 Intended use
The SONOCOOL ultrasonic bath is intended for use in laboratories and facilities for
industrial and scientific research as well as material testing institutes. With the bath
it is possible to use the catalytic effect of ultrasound for processes during which
simultaneous cooling is required. Heat-sensitive samples are protected by the cooling
function and process sequences can be designed to be faster and more effective than
customary procedures.
The device is intended for commercial use.
The target group for SONOCOOL ultrasonic baths is trained specialists in laboratories
or research facilities.
1.2 Mode of operation
With the bath it is possible to use the catalytic effect of ultrasound for processes during
which simultaneous cooling is required. Heat-sensitive samples are protected by
the cooling function and process sequences can be designed to be faster and more
effective than customary procedures.
In addition to the temperature, the runtime can be set for up to 99:59:59 hours.
Four different levels of ultrasonic power can also be selected. The ultrasonic
bath is table-top operated using the keys on the front of the device, and is designed
for unmonitored continuous operation.
1.3 CE conformity
The device satisfies the CE-marking criteria of the European Union:
- Low-Voltage Directive
- Electromagnetic Compatibility Directive
- RoHS Directive
in their currently valid versions.
The declaration of conformity can be requested from the manufacturer.

1.5 Warnings and safety instructions
General
• Keep the ultrasonic bath out of the reach of children and of persons who have not been
instructed in its operation by reference to these instructions.
• We will not offer any guarantee for damages to the ultrasonic bath or oscillating tank,
or to the objects to be treated, as a result of use of inadequate disinfection agents
or detergents.
• Do not expose the ultrasonic bath directly to sunlight and do not position it in the vicinity
of heat sources.
• Keep the surface of the ultrasonic bath and operating elements clean and dry.
• Do not expose the ultrasonic bath to corroding influences.
• Move the ultrasonic bath only when it is empty.
• Empty the ultrasonic bath only while turned off.
• Ultrasonic baths adhere to prescribed EMC limit values, such that it can be assumed
that the electromagnetic radiation emanating from the devices is harmless to humans.
A binding statement for wearers of implants can only be made at the place of work
and together with the implant manufacturer. In case of doubt, information regarding
the allowable electromagnetic exposure level should be obtained from the implant
manufacturer.
