Basic heating transfer medium requirements
• Do not use media which are corrosive against the heating bath and its subcomponents or the
evaporating ask. E.g. add a sucient 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 ammable substances in the heating bath.
• Do not use heating transfer medium with a ash point below 200 °C
• At liquid exchange, the heating bath must be clean and dry
!
DANGER
Death or serious burns by deagration 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 unsuciently low for
evaporation tasks.
• Drain and clean the bath regularly to maintain the system in good working order.
• Ambient humidity can diuse 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 ask rotate and heat up the bath above 100 °C for some minutes.
