Step 2 :
Degas the liquid
Freshly-
fi
lled bath liquid or liquid 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.
Step 3 :
Preheat the liquid
In ultrasonic baths with built-in heating, the liquid may be preheated independently of
the ultrasound. This increases the ultrasound e
ff
ect, especially when removing fats, oils
and polishing paste residue, and shortens the duration of the subsequent ultrasound.
Remove basket and other accessories from the oscillating tank.
Place lid on top.
Use the turning knob to set the desired temperature, see chapter 3.1.2.
For a uniform warming of liquids, stir the liquid now and then or switch on the
ultrasound for a few minutes, otherwise there will be a retardation of boiling – risk of
scalding!
Step 4 :
Insert the objects to be sonicated
Before every sonication it is necessary to check whether the sonication
fl
uid needs to
be cleaned or replaced.
Hang the insert basket with the goods to be treated.
Check that the objects to be treated are fully covered with liquid.
With every object inserted, the
fi
ll level is to be controlled.
For cleaning tasks
Place the objects to be cleaned in the appropriate accessories, in doing so please note:
• Arrange parts evenly, do not stack them.
• Overloading the basket reduces the ultrasonic e
ff
ect (ultrasound will be absorbed).
• More heavily soiled sides should face downward.
• Open out parts with joints before placing in the basket.
• Fragile parts must not be touching each other.
• For technical reasons, the ultrasonic e
ff
ect is weaker on the outlet side. Do not place
more heavily soiled objects in the basket over the outlet.
