b) Setting of the timer
Timer
For cleaning periods of up to 15 minutes use the timer with automatic
switch-off. The required cleaning period is set by turning the knob. After the
set period the ultrasound is switched off automatically. If you need to switch
off the unit before the set period is over turn the timer knob back to the OFF
position.
Permanent Operation
If you require a cleaning period longer than 15 minutes turn the knob to the
infinity position. In this operation mode the unit has to be switched off by
hand.
c) Heating
The heating is switched on and off by the green button (fig. 1). Ensure that
the filling level in the tank is correct before switching on the heating. This
prevents overheating of the tank at the spot where the heating is fixed.
Please note that the liquid will heat up by ultrasonic activity alone without
heating. This effect is even stronger when a cover is used.
Heating and ultrasound can be operated separately. Higher temperatures
usually shorten the cleaning period considerably.
As ultrasonic activity additionally heats up the cleaning liquid do not set the
temperature too high when operating the unit over longer periods.
