4.1.
Operating elements
The devices have a mechanical timer which allows an adjustable time set of ultrasonic operating up to 30 minutes or
continuous operation. For on-times below 2 minutes, first of all turn the knob to a longer time and then turn it back to
the desired value. The continuous ultrasonic operation is obtained by turning the rotary knob anti-clockwise from the
'0' position over the latching point.
The ultrasonic energy applied to the fluid is visible in the form of undulations on the surface of the fluid.
USC100TH: An orange indicator in the heater switch lights up when the heater is enabled. The temperature is preset
fixed to 65degC.
USC200T, TH: During ultrasonic operation a green indicator lights up. The USC200TH has additionally a green
indicator when the heater is enabled and a yellow indicator if the set temperature is not reached. To adjust the
desired set temperature turn the knob to the desired value (in degC).

Ultrasonic cleaning
Immerse the items to be cleaned in the cleaning bath, the distance of the items from the bottom must be at least
20 mm (0.8 inches). If required, use the cleaning basket which is available as an accessory.
Set the required cleaning time and temperature for the cleaning process (if applicable). The value excessively
depends on the cleaning fluid, temperature, type and degree of soiling of the items requiring cleaning. The time
can vary from a few seconds to a few minutes. The best combination of the parameters may have to be
experimentally determined.
Start the cleaning process by switching on the ultrasonic operation.
After the cleaning process remove the items out of the liquid with suitable care. We recommend rinsing the parts
in clean water.
Disconnect the ultrasonic cleaning unit from mains if the unit is not needed.
WARNING:
Consider the temperature tolerance of the material to be cleaned!
Please note that the bath temperature rises considerably with duration of the ultrasonic operation and
can exceed the set temperature.
Never put the items to be cleaned directly on the bottom of the tank.
Never clean too many items at once, the cleaning result can deteriorate.
4.3.
Emptying the tank
If the cleaning result becomes worse or if the cleaning liquid has got contaminated, the cleaning liquid must be
replaced.
Prior to any emptying or cleaning the unit must be disconnected from mains.
