Maintenance and repair
6.1 Maintenance
SONOREX TECHNIK ultrasonic/rinsing baths are maintenance-free.
For purposes of regular inspection, the following functional checks may be carried out.
6.2
Functional checks
Checking control lights
• Pursuant to chapters 3.1.1 and 3.1.2.
Checking the ultrasound and/or heating
The function can be checked using a standard wattmeter. It should be inserted between
the ultrasonic bath's mains plug and the socket.
• Fill the tank with
fl
uid, see chapter 4.2.
• For testing purposes, only the ultrasound or only the heating system should be
plugged in. Next, the value displayed is to be compared with the corresponding value
in the technical data (chapter 1.4) (tolerances ± 20 %).
Checking the ultrasound effect
• For this check, it is recommended that a foil test be conducted (semi-annually).
Ordinary aluminium foil is used to conduct the test. Next, a comparison is made with
previously-generated foils, if applicable.
Detailed information available upon request.
Check the fl oat switch
The
fl
oat switch is situated directly in the tank and is therefore a wear part.
The function and tightness of the
fl
oat switch must be checked at regular intervals.
If the tank is already full, the
fl
oat must rise to the upper limit stop (upper ring).
In an empty tank, the rising ability of the
fl
oat can be easily tested using a beaker
fi
lled with water, or similar. To do so, raise the beaker from below over the
fl
oat - it
must rise upwards.
If
the
fl
oat or
fl
oat switch are defective, they must be replaced since the safety of
the bath is no longer guaranteed (order No.: 3112 - black
fl
oat; 3111 - white
fl
oat;
3105 -
fl
oat switch complete).
