Warnings and safety precautions
General
• Keep the device and accessories out of the reach of children and also of persons who have not
been instructed in their operation by reference to these instructions.
• The use of the device or parts thereof on humans or animals is not authorised.
• Keep the HF generator and operating elements clean and dry.
• Do not expose the unit to corroding in
fl
uences.
• When working with the device, please observe hygiene instructions pursuant to chapter 5.2.
• The connection of any type of power or voltage sources to signal inputs or outputs is forbidden.
• All plug connections (such as for ultrasonic transducers, foot switches) may only be plugged or
unplugged while the device is turned off.
• The
HF generator and ultrasonic transducer may only be transported separately.
• The homogenizers adhere to prescribed EMC limit values, such that it can be assumed that the
electromagnetic radiation emanating from the units 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 is to be obtained from the implant manufacturer.
Operation
• Observe ambient and set-up conditions, see chapter 1.4.
• Determine the mains voltage before connecting the HF generator. Only connect the HF
generator to a grounded socket.
•
Fuse protection 10 A (main circuit breaker).
• The metallic ultrasonic transducer system must not be turned inside the black housing of the
ultrasonic converter. This would destroy the ultrasonic transducer system and its electrical
connections. The plastic clamping ring must not be loosened.
• Before each startup, check that the probe is
fi
rmly positioned; if necessary, tighten the probe
(see chapter 4.3.1).
• Do not touch any oscillating parts during operation! Damage to health is possible.
• Do not touch the sonication vessels with the oscillating probe - probes and vessels could be
damaged.
• Warning, risk of splashing!
This is especially the case with small sample quantities and when immersing oscillating probes.
• Do not use combustible solvents in open reaction vessels since the operating safety of
the homogenizer could be compromised. Safe extraction of combustible vapours must be
guaranteed. When using a sound proof box, the vapours cannot escape.
• Before any mounting or dismounting (chapter 4.3.1) of probes, turn off the device and
disconnect the ultrasonic transducer from the HF generator.
• Only use the prescribed tool for mounting and dismounting (see appendix B).
• Do not use any bent probes (
unstable operation, loss of power).
•
Liquids must not penetrate the inside of the ultrasonic transducer.
• Only the ultrasonic converter UW mini20 may be connected to the HF connection.
• Do not operate the device without supervision.
