Tempering flammable liquids:
For tempering flammable liquids, an external On/Off temperature con-
troller (not included with the magnetic stirrer) is required and must be
installed. The controller switches off the magnetic stirrer before the
media reaches the ignition point.
Safety feature:
The unit has an additional internal temperature sensor which will shut
the heating function off, in the event of a temperature control mal-
function.
Switch off the heat control knob, allow the unit to cool down, and then
switch the heat control knob on again.
Cleaning
• Unplug the magnetic stirrer.
• Clean carefully with a damp cloth and warm water.
• Do not clean with acetone or other organic liquids, except
alcohol.
• In extreme cases mild alcohol may be used.
• Rinse and dry thoroughly.
• To avoid electrical shock, do not open the housing. Refer
servicing to qualified personnel only.
