Maintenance / Care
Pull the mains plug before carrying out any maintenance
works!
Check the casing and the mains cable for damage regularly in
order to prevent electrical accidents.
Lime deposits on the stainless-steel tank can be cleaned gently
e.g. with elma clean 40 or elma clean 115C (operate the unit
with conce water).
Residues of cleaning media can be wiped away with a
household cleaner or decalcifier depending on the kind of
contamination. Do not put the unit in or under water
!
If the unit is used for medical and sanitary purposes it is
necessary to disinfect the transducer tank and the surfaces
regularly (standard surface disinfectants).
9.2
Service life of the transducer tank
The transducer tank and particularly the ultrasound transmitting
surfaces are wear parts. The changes on the surfaces that
occur after a certain operating period are visible first as grey
areas and later on as material abrasions, the so-called
cavitation erosion.
To prolong the service life of your ultrasonic unit even more we
recommend to observe the following instructions:
Regularly remove any cleaning residues, in particular metal
particles and rust films.
Use suitable cleaning chemicals, with particular caution
concerning the kind of removed contamination (see
instructions
section 8.2
Exchange the cleaning medium before it is too heavily
contaminated.
Do not operate the ultrasound unnecessarily; switch off after
the cleaning process.
