The device may only be used under the following circumstances:
The device is in full working order.
The device is used according to its intended purpose.
All operators of the device possess the necessary safety and risk awareness.
The instructions stipulated in this instruction manual are followed.
Errors must be eradicated immediately; especially those which jeopardize safety.
Intended use
The device is a magnetic stirrer with a heating function, suitable for continuous operation. The device stirs
and/or heats substances in a container. A magnetic stir bar, which is guided by a magnet, moves to administer stirring.
A suitable operating location for the device is one of the following areas:
Chemical and biological laboratories in industry and universities
In order to use the device according to its intended use, please also observe these operating instructions, the
safety instructions and the instructions provided for cleaning (see chapter "Cleaning").
Uses not permitted
Any use which deviates from the device's intended use is considered to be improper. The manufacturer does
not accept liability for any damages resulting from non-permitted uses. The risk is carried by the operator
alone.
Do not use the device in potentially explosive areas. The device is not protected against explosion.
Do not insert any objects into the area between the hotplate, the cover plate and the base of the device.
Do not cover the ventilation slots.
Use in potentially explosive areas
Do not use the device in potentially explosive areas. The device is not protected against explosion. There
is no explosion or ATEX protection available.

Operating personnel’s obligations
NOTICE
Operating instructions
These operating instructions must be followed, read and understood by all persons work-
ing on the device (acknowledgment of the safety instructions is particularly important).
Ensure that work which uses naked flames is not carried out in the vicinity of the device (risk of explo-
sion).
Ensure that the flow rate when removing liquids with flammable materials remains at < 1 m/s (electro-
static charge; risk of ignition).
Ensure that gases classified in explosion group IIC are not produced by materials or during chemical reac-
tions, e.g. hydrogen.
Ensure that no devices are operated or assembled which are emission or radiation sources (electromag-
netic waves) for the frequency range (3×1011 Hz bis 3×1015 Hz).
Ensure that no devices are operated or assembled which constitute emission or radiation sources for ioniz-
ing radiation or in the ultrasonic range.
Ensure that no adiabatic compression or shock waves occur (shock wave combustion).
Please wear the appropriate protective clothing when working on the machine (protective glasses and if
necessary, safety gloves).
Ensure that sufficient heat transfer media are used.
Ensure that the correct heat and cold protection is used in relation to the media implemented.
Please avoid putting pressure on the display.
Personnel qualification
The target group for this device is qualified personnel. The device may only be operated by individuals who
have been instructed in its proper use by qualified personnel.
Safety-conscious operation
