Maintenance and repair
6.1
Maintenance
To achieve a consistent sonication quality, the ultrasonic bath is to be inspected at regular
intervals.
Check the LC display
Switch on the ultrasonic bath - the display must light up.
Cleaning the cooling system (once per year)
The integrated cooling unit and the pump must be rinsed at regular intervals to prevent
deposits caused by the circulating contact
fl
uid.
Checking the
fl
ow:
The
fl
ow rate must be approx. 3.5 l/min.
Connect the hose to the emptying nozzle. Please also refer to Chapter 4.4.
Place an empty bucket underneath and provide a bucket
fi
lled with contact
fl
uid for
replenishment.
Note: During the check, ensure that the pump is running at all times. The tray’s
fi
ll level
must be above the intake and
fi
ll level sensor. It must be constantly replenished.
Switch on the ultrasonic bath.
Open the shut-o
ff
valve for 1 minute. Permanently replenish the liquid to ensure that
the
fi
ll level sensor is constantly immersed in it.
Close the shut-o
ff
valve.
3.5 litres of liquid should be in the bucket after 1 minute.
If the bucket is
fi
lled with approx. 3.5 litres, rinsing is not necessary. If the
fl
ow rate is
clearly below
<< 3 l/min
this, rinsing must be carried out.
Please refer to the following section.
Performing the rinsing process:
For rinsing, we advise using: TICKOPUR TR 13 (at a dose of 5%)
Drain the contact liquid. Please also refer to Chapter 4.4.
Prepare the rinsing liquid:
Fill a bucket with 4.75 litres of lukewarm water and 250 ml of TICKOPUR TR 13.
Close the shut-o
ff
valve and carefully add the prepared rinsing liquid. The oscillating
tray can be
fi
lled beyond the
fi
ll level mark.
If there is any contact
fl
uid remaining, the rinsing liquid may not fully
fi
t in the tray.
Set the bath temperature to 40 °C and leave the ultrasonic bath to run for at least
1 hour (the liquid should heat up).
Drain the rinsing liquid.
Close the shut-o
ff
valve and
fi
ll with clear water. Start up for 5 minutes (with and without
cooling).
