5.5 Heating bath
As soon as the mains plug is plugged in, the bath starts to
warm up, provided the main switch is turned on. Thus, make
sure that there is always heating bath liquid in the bath.
Temperatures up 180 ° are possible with the heating bath.
To avoid accidents:
• Never remove rotating flasks from the bath because
splashing oil can lead to burns
• Make sure that no liquid can flow from the bath when the
evaporating flask is submerged.
• Installation of protectiv shield only if if heating bath is cold.
If the desired temperature is set via the turn button-the display
jumps from ACTUAL to SET point. The DESIRED temperature
can now be set. After approximately 2 seconds, the display
jumps back to the ACTUAL value.
The temperature scale via the SET point potentiometer is 2-
coloured. Blue marks the water range, i.e. the temperature
range below 100 °C, orange marks the oil range, i.e. tempe-
rature above 100 °C. For safety related reasons, when activities
are performed above 100 °C, the regulator is to be turned
over the 100 °mark against a mechanical resistance.
To be able to regulate the upper range, heat transfer oil for a
operating range up to 250 °C must be used.
