Notes - Temperature and heating
• Heated
fl
uids intensify the ultrasound effect. Experience has shown that the best
results are obtained with a bath temperature of 50 to 60 °C. At higher temperatures,
the effect of the ultrasound cavitation decreases again, however
1
.
• In order to save time during use, the bath
fl
uid may be preheated during degassing.
• Ultrasound energy warms up the sonication
fl
uid (even without additional heating).
Through continuous sonication and/or by covering the oscillating tank, the
fl
uid
temperature may increase faster and even rise above the maximum adjustable value
of the thermostat (80 °C). For this reason, check the temperature when treating
temperature-sensitive components.
• For an optimum bath temperature, observe the speci
fi
cations from the preparation
manufacturer!
• To protect the electronic components inside the ultrasonic bath, the ultrasound
output is reduced upon reaching a critical temperature in order to inhibit a further
increase in the interior temperature.
• The
fl
uid in the oscillating tank may not exceed a maximum operating temperature of
100 °C.
• Cover the ultrasonic bath when in continuous operation so that not too much bath
liquid evaporates.
• For safety reasons ultrasonic cleaning baths and rinsing baths should be
covered when not in operation, to prevent operating and external personnel from
inadvertently coming into contact with the bath liquid or being injured by liquids that
are still hot.

General use
Step 1:
Fill oscillating tank
The oscillating tank is
fi
lled with water and a suitable preparation to reduce the surface
tension, see chapter 7.3.
Fill 1/3 of oscillating tank with water.
Add dosed preparation to the oscillating tank.
Fill carefully up to the
fi
lling level mark, avoid the formation of foam as much as
possible.
Step 2:
Degassing the fl uid
Freshly-
fi
lled bath
fl
uid or
fl
uid that has remained in the oscillating tank for a longer
period of time must be degassed prior to use. See also chapter 4.3.1.
Remove basket and other accessories from the oscillating tank.
Place lid on top.
Turn on the ultrasound with the turning knob and sonicate for 30 min for degassing,
see chapter 3.1.1.
