5 Putting into operation

57 R-220 SE Operation Manual, Version F

Basic heating transfer medium requirements

• Do not use media which are corrosive against the heating bath and its subcomponents or the

evaporating ﬂask. E.g. add a sufﬁcient amount of borax when deionized water is used!

• The medium must be liquid at room temperature.

• Do not mix liquids of unknown composition!

DANGER

Death or serious burns by use with highly ﬂammable substances in the heating bath.

• Do not use heating transfer medium with a ﬂash point below 200 °C

• At liquid exchange, the heating bath must be clean and dry

DANGER

Death or serious burns by deﬂagration of hot heating bath liquids.

• Do not mix or add water to other heating transfer media with a higher boiling point

• The replenishment valve must not be connected to a water source when another heating

transfer medium than water is used

NOTE

• Do not switch on the heating when the heating transfer medium level is unsufﬁciently low for

evaporation tasks.

• Drain and clean the bath regularly to maintain the system in good working order.

• Ambient humidity can diffuse into the heating medium and condensated water can gather at the

bottom when the bath has not been used over a longer period. To drive out unwanted water let

the evaporating ﬂask rotate and heat up the bath above 100 °C for some minutes.
