4.4 Refresh / replace the contact liquid.
The contact liquid in the ultrasonic bath must be regularly replaced.
Layers of contamination on the tank bottom reduce the ultrasonic output.
The oscillating tank is to be emptied and cleaned after a long period of use or sonication of
heavily soiled objects. For additional information, see chapters 4.5.4 and 5.1.
In order to replace the contact liquid, the ultrasonic bath is emptied out as described below
and re
fi lled in accordance with chapter 4.1. After fi lling, it is turned on for approx. 5 minutes
(without ultrasound). The integrated pump starts working automatically and thoroughly
fl ushes the ultrasonic bath.
Repeat the emptying, fi lling and fl ushing process two or three times.
In order to drain the contact liquid, please proceed as follows:
 Switch o ff the ultrasonic bath ( mains switch on the rear side).
 Remove the protective cover from the emptying nozzle and slide the supplied ¼" drain
hose onto the emptying nozzle. Place
the other end of the drain hose in a
suitable recipient or in the sink.

Insert the rubber stopper in the inlet
(see chapter 4.1).
 To open the shut-o ff valve, turn it in a
clockwise direction to the dead stop.
 Empty the ultrasonic bath as much
as possible. To do so, slightly tip the
ultrasonic bath toward the left, along its
long side where the emptying nozzle is located.

After emptying, close the shut-o ff valve once again. If necessary, remove the hose and
cover the emptying nozzle with the cap.

In order to keep the ultrasonic bath in hygienic condition, it is recommended that the
oscillating tank be thoroughly rinsed after emptying.
Notes:
• For transportation purposes, the ultrasonic bath must be emptied to the extent possible.
Next, seal both of the tank's openings for the in fl ow and out fl ow (see chapter 4.1) with
the rubber stoppers supplied.
• A complete emptying of the ultrasonic bath is not possible. A small amount of contact
liquid always remains in the ultrasonic bath.
