Settings at the heating bath
6 .1 .1
Setting the heating bath temperature
ATTENTION
As soon as the power plug is connected and the mains switch is turned on, the bath starts heating if
the actual temperature is below the set temperature. For this reason, make sure that there is always
heating medium in the bath to prevent heating bath damage.
WARNING
The heating bath can reach temperatures up to 180 °C. To avoid burns, consider the following:
• Never remove a rotating flask from the bath because splashing oil can result in burns.
• Make sure that no liquid can overflow from the bath when the evaporating flask is submerged.
• Install the protective shield (optional accessory) only to a cold heating bath.

to oil bath mode, proceed as follows:
• Switch off the heating bath.
• Turn the adjusting knob to any position except
for 0 °C or 180 °C.
• Switch on the heating bath.
• As soon as the temperature is indicated on the
display, turn the knob to the 180 °C position
within 3 seconds. The indication “OIL” will now
appear on the display.

ATTENTION
In the oil bath mode, always operate the bath with oil as the heating medium as water might start
boiling and evaporating which would lead to a heating bath damage.
After the oil bath has been standing opened for a prolonged period, condensation water can accu-
mulate at the bottom. When the bath is used again, it must be heated above 100 °C with rotating
flask to drive the water out.
NOTE
A setting up to 180 °C is only possible in oil bath mode.
