Warning 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 of its parts on humans or animals is not authorised.
•
Keep the HF generator and operating elements clean and dry.
• Do not expose the unit to corroding forces.
•
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 the signal inputs or outputs is
forbidden.
•
Signal wires for foot switches, temperature sensors, etc., may not exceed a maximum length of
3 m.
• 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 must be transported separately.
• The
homogenisers HD 2070 and HD 2200 adhere to prescribed EMC limit values, so 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 1.4.1.
• Determine the local mains voltage before connecting the HF generator, activate the switch if
needed.
• Only connect the HF generator to a grounded socket.
Fuse protection 10 A (main circuit breaker).
•
The ultrasonic transducer should only be
fi
rmly mounted on the black housing using a suitable
support, e.g. stainless steel stand.
• Before each startup, check that the probe is
fi
rmly positioned on the standard or booster horn; if
necessary, tighten the probe (see chapter 4.3.1).
• Do not touch any oscillating parts (e.g. standard or booster horns, micro tips or tapered tips,
titanium plates, ultrasonic transducer) during operation! Damage to health is possible.
• Do not touch the sonication vessels with the oscillating probe - probes and vessels could be
damaged.
• The
sonication of liquids generates noise. Suitable accessories, such as a sound proof box,
will minimise such noise considerably. If operating without a sound proof box, wear hearing
protection.
• 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 homogeniser 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 4.4) of probes or standard/booster horns as
well as accessories, turn off the device and disconnect the ultrasonic transducer from the HF
generator.
