5.1
Heating up of the cleaning liquid
Depending on the degree and kind of contamination and on the
cleaning medium used it is recommendable to heat up the
cleaning liquid.
Switch on the heating. The yellow control lamp "heating" is
turned on.
Turn switch
„heating“ to position
„on“
Select the required cleaning temperature. The tank must be
filled at least half. The optimum filling level is marked on the
tank wall (page 7 - illustration 4.1).
Setting of
temperature at
thermostate
In order to achieve a uniform heating of the cleaning liquid it is
necessary to switch on the ultrasound from time to time or to
stir the liquid.
Without stirring of the liquid the heat will rise to the surface.
There will be a considerable gradient of temperature within the
cleaning tank (the temperature difference between the liquid
surface and the bottom of the tank can be as high as 40°C).
Also, lime settings will form around the heating element
because the high temperature is not fully transmitted to the
liquid.
5.2
Placement of cleaning items
Caution!
Do not place the cleaning items directly on the bottom
of the transducer tank as this might lead to damages on the
unit.
Put the cleaning items into the stainless-steel cleaning basket.
