3. Temperature-sensitive or easily flammable media in the rotary
evaporator
When the pre-set bath temperature may not be exceeded under
any circumstances set the safety circuit as described below.
Setting the safety circuit
• Once the desired temperature of the medium has been reached
and the "Heating" signal lamp has blinked three times, the
safety circuit can be set.
• Using a suitable tool, slowly turn the adjustment knob (F) coun-
terclockwise until the red signal lamp lights up.
• Then press and slowly turn the adjustment knob (F) clockwise.
Once the red signal lamp goes out, turn the adjustment knob (F)
a little bit more in a clockwise direction so that the temperature
of the safety circuit is somewhat higher than the pre-set target
temperature (Turning the adjustment knob (F) by 5° corresponds
to an increase in the safety temperature of approximately 8 K).
Reset
Press the operating knob (F).
