). The
green LED in the key indicates the operation in
dynamic
mode.
Dynamic
can be switched on or off as required during
operation.
Cleaning items with sensitive surfaces may be adversely
affected by a combination of
dynamic
and 25 kHz. Please treat
sensitive items at 25 kHz plus
dynamic
for short periods only.
Also, the sound-giving surface of the cleaning tank is subject to
a higher degree of cavitation erosion.

Ultrasonic cleaning process
Please observe the following instructions before starting the
ultrasonic cleaning process.
Risk of scalding by hot surfaces and cleaning liquid!
Ultrasonic energy is physically transformed into heat.
The unit and the cleaning liquid in the tank heat up during
ultrasonic operation even with the heating switched off.
During permanent operation with cover temperatures exceeding
60°C can be reached.
During permanent operation with cover and heating
temperatures exceeding 80°C can be reached.
Do not reach inside the bath.
If necessary touch unit and basket with protecting gloves!
Ultrasonic units can produce annoying sounds.
Wear personal ear protection devices when working close to an
ultrasonic unit which is operated without cover.
Sensitive surfaces may be adversely affected by ultrasound
during prolonged periods of ultrasonic treatment, in particular at
lower ultrasonic frequencies.
Ensure that sensitive surfaces are exposed to ultrasonic activity
for a suitable period only.
If in doubt check the cleaning progress regularly and observe
the state of the surface material.
Ultrasonic energy is physically transformed into heat.
The unit and the cleaning medium in the tank heat up during
ultrasonic operation even with the heating switched off.
