7.3 Automatic mixing of the
liquid during heating up
Without mixing of the liquid the generated heat will
rise to the surface of the bath. This will cause a
strong gradient of temperature inside the cleaning
tank. In order to ensure an even heating-up of the
cleaning liquid, it makes sense to mix the liquid from
time to time, e.g. by means of ultrasound.
This Ultrasonic cleaning unit is equipped with an ad-
ditional mixing device which guarantees the optimum
mixing of the cleaning liquid during the heating up
process.
f
unctioning
The ultrasound is activated for operating periods of
approx. 5 seconds each with one-minute breaks in
between.
h
ow to Proceed
1. press the on/off key to start the unit
2. select the required cleaning period (set period)
3. set the required temperature
4. to start keep the ►■ key pressed for > 2 sec
(see chart chapter 4.6)
Operation only when set temperature >
actual temperature.
7.4 Starting the cleaning
process manually
Press the on/off key to start the unit.
s
elect the cleAning Period
Set the required cleaning period with the turning
knob.
The LED display indicates the set period.
s
hort Period oPerAtion
For short period operation set the required cleaning
period at the turning knob.
Press the ►■ key to start the ultrasonic operation.
The unit starts the ultrasonic cleaning process.
The remaining period is indicated in the blinking LED
display.
The ultrasound is automatically switched off when the
set period has run down.
P
ermAnent oPerAtion
For permanent operation turn the turning knob clock-
wise into ∞ position. In this operating mode there is
no automatic switch-off. The ultrasonic activity must
be switched off by hand after the cleaning process
has been finished; press the ►■ key to switch of.
Alternatively, turn the turning knob back into "0" posi-
tion.
Caution: Do only turn the turning knob anti-
clockwise into "0" position!
EN
In order to avoid unintended permanent
operation, the Ultrasonic cleaning unit is
equipped with a safety switch-off automati-
cally. The unit switches off completely after
12 h permanent operation. In case you wish
to continue operation start the unit again.
7.5 Sweep function
This Ultrasonic cleaning unit is equipped with an
optional sweep function.
f
unctioning
A more homogeneous sounding of the cleaning bath
is achieved by the continued displacement of the
sound pressure maxima in the cleaning liquid.
Particularly for large cleaning items it may be useful
to switch on the sweep function.
h
ow to Proceed
Press the sweep key to switch on or off.
Sweep and degas functions cannot be ope-
rated at the same time.

uP treAtment of cleAning items
When the cleaning process is finished rinse the
cleaning items, e.g. under the tap.
d
rAin the unit
Caution! Electric shock hazard!
Disconnect from the mains before emptying
the tank! Make sure no detergent spills into
the socket during emptying.
Drain the liquid as soon as it is dirty or when the unit
is not operated over a prolonged period of time.
Certain residues and types of contamination may
destroy or damage the stainless steel tank.
Advice:
Empty by tipping the unit over the appli-
ance side at the back right hand side.
Ensure that no abrasive residues (plaster,
investment material, polishing residues,
metals, etc.) remain in the ultrasound tank,
danger of cavitation corrosion!
