tetrahydrofuran, as well as unsaturated hydrocarbons, such as tetralin, diene, cumene and aldehydes, ketones
and solutions of these substances.
DANGER OF BURNING! The heating bath, tempering medium, evaporator piston and glass assembly can
become hot during operation and remain so for a long time afterwards! Let the components cool off before
continuing work with the device.
ATTENTION! Avoid delayed boiling! Never heat the evaporating flask in the heating bath without
switching on the rotary drive! Sudden foaming or exhaust gases indicate that flask content is beginning to
decompose. Switch off heating immediately. Use the lifting mechanism to lift the evaporator piston out of the
heating bath. Evacuate the danger zone and warn those in the surrounding area!
• When the device is switched off or the power supply disconnected, the internal safety lift removes the
evaporator piston from the heating bath.
CAUTION! Never operate the device when the evaporator piston is rotating and the lift is raised. Always
lower the evaporator piston into the heating bath first before starting the rotation drive. Otherwise hot
tempering medium may be sprayed out!
• Set the speed of the drive so no tempering medium is sprayed out as a result of the evaporator piston
rotating in the heating bath. If necessary reduce the speed.
• Do not touch rotating parts during operation.
• Imbalance may result in uncontrolled re
sonance behaviour of the device or assembly. Glass apparatus may be
damaged or destroyed. In the event of unbalance or unusual noises, switch off the appliance immediately or
reduce the speed.
• The appliance does not start up again automatically followin
g a cut in the power supply.
• The device is only disconnected from the power supply network if the device power switch is off or the plug is
pulled out.
• The socket for the mains cord must be easily accessible.
• The voltage stated on the type plate m
ust correspond to the mains voltage.
• Socket must be earthed (protective ground contact).
• Removable parts must be refitted to the appliance to prevent the infiltration of foreign objects, liquids etc.
• Protect the appliance and accessories from bump
s and impacts.
• The appliance may only be opened by experts.
