Cleaning and maintenance of the homogeniser
To achieve an optimum lifespan for the homogeniser, cleaning and maintenance are to be
conducted regularly.
CAUTION:
Always disconnect the homogeniser from the mains before performing cleaning/maintenance.
Do not rinse or immerse the homogeniser in water and do not expose it to splash water.
A warranty will not apply to damage caused by the use of unsuitable disinfection agents
or detergents.
5.1
Cleaning and care
Probes
All probes are subject to process-related wear, which leads to erosion on the sound-emitting
surface and thus to a reduction in power.
In the case of frequent use, it is recommended that an inventory supply of probes be kept.
Examples of wear, e.g. on titanium plate TT 13:
The sound-emitting surfaces can be carefully polished or milled a few times. If material residue
due to erosion or post-processing exceeds a value of approx. 1 mm, or if there is no power display
on the generator, the probe is non-resonant and can no longer be used.
Reconditioning of the sound-emitting surface:
Reconditioning can be performed using a grinding machine with a
fi
ne grinding wheel of suitable
grain size, or by hand using a diamond
fi
le. Suitable grinding materials are, for example:
•
Fine abrasive wheel, polyurethane-bound – grain size 150
•
Fine abrasive wheel, rubber-bound – grain size 120
•
Grinding wheel PNK, corundum – grain size 180 ... 280
• Diamond
fi
le, D 181 or D 251
Ultrasonic transducer/ ultrasonic generator
• Do not use any abrasive cleaners, only commercial care products without abrasive additives.
•
Housing is to be wiped o
ff
only from the outside, use a suitable surface disinfectant if needed.
Afterwards, allow to dry o
ff
or wipe dry.
