Initial operation

 According to the laboratory instrument standards EN / IEC 61010-2-020 an emergency switch to separate power
supply in the event of a failure must be installed in the building electrical system.
This switch has to be placed remote from the centrifuge, prefered outside of the room in which the centrifuge is
installed or near by the exit of this room.

Position the centrifuge in a stable and level manner in a suitable place. During set-up, the required safety
margin of 300 mm around the centrifuge is to be kept according to EN / IEC 61010-2-020.
When the centrifuge is running, according to EN / IEC 61010-2-020, no persons, dangerous
substances or objects may be within the safety margin of 300 mm around the centrifuge.
 Do not place any object in front of the ventiduct.
Keep a ventilation area of 300 mm around the ventiduct.
 Check whether the mains voltage tallies with the statement on the type plate.
 Connect the centrifuge with the connection cable to a standard mains socket. For connection ratings refer to
Chapter "Technical specifications".
 Turn on the mains switch (Switch position "").
The machine type and program version will be displayed and the LEDs light up.
displayed after 15 seconds.
 Open the lid.
The last used centrifuge data will be displayed.
 Remove the transport safety device (see instruction sheet on "Moving the equipment safely").

Installation and removal of the rotor


Clean the motor shaft (C) and the rotor drilling (A), and lightly grease the motor shaft
A afterwards. Dirt particles between the motor shaft and the rotor hinder a perfect seating
of the rotor and cause an irregular operation.

Place the rotor vertically on the motor shaft. The motor shaft dog (D) has to fit in the
rotor slot (B). The alignment of the groove is labelled on the rotor.
B

Tighten the rotor tension nut with the supplied wrench by turning in a clockwise
direction.
C

Check the rotor for firm seating.
D

Loosening the rotor: Loosen the tension nut by turning in a counter clockwise direction,
and turning until the working point for lifting. After passing the working point for lifting
the rotor is loosened from the motor shaft cone. Turn the tension nut until the rotor is
able to be lifted from the motor shaft.
