3.3. For protection of the equipment
You have received a product designed for industrial and experimental use. Nevertheless, avoid strikes to the housing,
vibrations, damage to the operating-element panel, and contamination.
Make sure that the mains power supply has low impedance to avoid any negative effects on instruments being
operated on the same mains.
Do not expose the unit to sunlight
Sudden drops may cause damage in the interior of the instrument.
Transport the instrument with care.
The device can be damaged when sucking in aggressive gases or vapor through the installed ventilator.
Press the power button to interrupt the stirrer, rather than disconnect the main power plug directly.
The voltage stated on the nameplate must correspond to the mains voltage.
Do not cover the device, even partially e.g. with metallic plates or film. This results in overheating.
Protect the appliance and accessories from bumps and impacts.
Ensure that the base plate is kept clean
Observe the minimum distances between devices, between the device and the wall and above the assembly (min.
800 mm).
