Operation
Display 'Temperatur / Temperature / Tempèrature'
(two digit, 'S/R','H/T', 'D' and 'D/HF' types only)
In cleaning mode, the current bath temperature is shown in degC in this display. If the pre-selected temperature has
not yet been reached, the decimal point in the display flashes; the bath is being heated. Once the pre-selected
temperature has been reached, the decimal point is steady. During the process 'Setting the bath temperature', the
target temperature for the cleaning bath is shown in the display.
Display 'Leistung / Power / Puissance' (single digit, 'D' and 'D/HF' types only)
The current set value of the ultrasonic power is shown in steps from 1-9 in this display. Step 9 corresponds to
maximum power (100%).
Setting the cleaning time
With ultrasonic switched off press the 'Auswahl / Select / Choix' button until the 'Zeit / Time / Durée' display flashes.
The desired cleaning time can be set in steps from 1 – 99 minutes with the '+' and '–' adjusting buttons.
The time pre-selection can be disabled by pressing the '-' button until two horizontal lines are
shown in the display ('- -').
Once the desired time has been set, release the '+' and '–' adjusting buttons and wait until the display stops flashing
(approx. 5 sec). The value is stored now.
Setting the bath temperature ('S/R', 'H/T' 'D' und 'D/HF' types only)
With ultrasonic switched off press the 'Auswahl / Select / Choix' button until the 'Temperatur / Temperature /
Tempèrature' display flashes. The desired liquid temperature can be set up to 80degC with the '+' and '–' adjusting
buttons.
Once the desired temperature has been set, release the '+' and '–' adjusting buttons and wait until the display stops
flashing (approx. 5 sec). The value is stored now.
Setting the ultrasonic power ('D' und 'D/HF' types only)
The ultrasonic power can be set during ultrasonic on or off.
Ultrasonic 'OFF':
During ultrasonic switched off press the 'Auswahl / Select / Choix' button until the 'Leistung / Power / Puissance'
display flashes. The desired power can be set in steps from 1 – 9 with the '+' and '–' adjusting buttons (step 9 = max.
power).
Once the desired power is set, release the '+' and '–' adjusting buttons and wait until the display stops flashing
(approx. 5 sec). The value is stored now.
Ultrasonic 'ON':
During ultrasonic switched on press the 'Auswahl / Select / Choix' button until the 'Leistung / Power / Puissance'
display flashes. The desired power can be set in steps from 1 – 9 with the '+' and '–' adjusting buttons (step 9 = max. E
power).
Once the desired power is set, release the '+' and '–' adjusting buttons and wait until the display stops flashing
(approx. 5 sec). The value is stored now.
Degassing the fluid (DEGAS, 'D' und 'D/HF' types only)
In order to obtain an optimum cleaning process after the unit has been refilled, first of all the liquid should be
degassed. The cleaning result is considerably impaired by the solved gas bubbles (usually ambient air) in the liquid.
Ultrasonic vibrations dispense these gases.
In the DEGAS mode the unit is periodically switched on and off, the gas bubbles can raise out of the fluid in the OFF
period.
Degassing can be speeded up by adding a few drops of a surface-active agent (e.g. washing-up liquid) to the
cleaning fluid.
Most ultrasonic cleaning agents already contain a surface-active agent.
The degassing process does not have to be repeated when reusing the cleaning liquid.
