CAUTION!
There is danger of serious burns when the hot plate is operating at temperatures over
3-8
50º C. You must not touch the hot plate, nor the vessel or the solution.
9-14
When heating flammable substances the hot plate temperature must be lower than the
substance flashpoint.
Note: Due to thermal coefficient of vessel materials, solution volume and temperature
4
loss by radiation, the solution temperature will always be lower than the temperature
adjusted on the hot plate.

Placing the thermometer

Placing the thermometer to control the temperature of the solution is an easy operation:

first, you should assemble the two parts of the rod (1.3) and insert it in its support (1.12) at
16
the back side of the equipment. Once the rod is placed ypu should put the bosshead (1.2) at
the desired height, hold it with the screw and put the clamp of the thermometer (1.1).
Once the stirring operation or your daily work is finished we highly recommend unplug-
ging the equipment, as it is provided with electric components that have a little electric con-
sumption, which involves an early ageing of the equipment, may provoke accidents due to
heating production or unnecessary waste of energy.
Security
The magnetic stirrer must be used by previously qualified staff that knows how it
works thanks to the user manual.
Put the magnetic stirrer in a horizontal, plane, stable table having a free space of at least
30 cm per side.
When working at temperatures over 50º C you must not touch the hot plate, nor the ves-
sel or the solution, as it may produce serious burns.
You should act with the utmost care when working with liquids than reach temperatu-
res higher than 100º C (for example, oil).
During operation, do not place the magnetic stirrer near any warm supply (burners,
blowlamps, etc.), nor expose it directly to the sun. Avoid vibrations, dust and dry envi-
ronments.
When heating flammable substances, the hot plate temperature must be lower than the
substance flashpoint.
In case the magnetic stirrer is not to be used for a long period of time please make sure
that it is unplugged from the net in order to avoid possible accidents.
It is essential to have the equipment switched off and unplugged from the net before
cleaning, checking components or replacing any piece (e.g. replacement of a fuse).
Never try to repair the magnetic stirrer by yourself, since you will lose the warranty and
may provoke damages to the general operating system or the electrical installation, as
well as injuries to the people that usually handle the equipment (burns, hurts...).
Try not to spill any liquid on the control panel, though it is properly insulated. In case
you have any doubts do please immediately unplug the magnetic stirrer (see
Maintenance).
Made under the European regulations for electrical security, electromagnetic compati-
bility and security on machines.
