Security
The centrifuge must be used by previously qualified staff that knows how the equip-
ment works thanks to the user manual.
Put the centrifuge on top of a horizontal, plane and stable table making a free space at
least at 30 cm per side. The ventilation grilles must be always completely free of obstruc-
tions.
Do not put the centrifuge near any warm supply (burners, blowlamps…), nor expose it
directly to the sun, etc. Avoid vibrations, dust and dry environments.
During operation, dangerous material such as flammable liquids or pathological mate-
rial should be out of the working area.
Nahita centrifuges are not suitable for treatment of flammable liquids, explosive sam-
ples or samples capable of forming explosive mixtures.
The centrifuge is provided with a safety switch that avoids operation if the lid is open
and that in case of opening the lid during operation automatically stops centrifugation. It
is also provided with an electromagnetic lock that locks the lid when the rotor starts spin-
ning. Never try to open the lid while centrifuge is operating.
When you are not using the centrifuge for a long period of time please make sure it is
unplugged 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 centrifuge 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 centrifuge (see Maintenance).
Made under the European regulations for electrical security, electromagnetic compati-
bility and security on machines.
