operation
•
According to the laboratory instrument standards EN 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.
•
Remove the transportation safety device from the bottom of the housing, see sheet ”Transportation safety device"
•
Position the centrifuge in a stable and level manner in a suitable place. When setting up the equipment, care
should be taken to provide the required safety area of 300 mm around the centrifuge in accordance with IEC
61010-1.
No persons and / or dangerous materials may be located within the safety zone when the centrifuge is
running.
•
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 "Appendix, Technical data/Technical specification".
•
Turn on the mains switch. Switch position "

B
A
•
Clean the motor shaft (C) and the rotor drilling (A), and lightly grease the motor shaft
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.
•
Tighten the rotor tension nut with the supplied wrench by turning in a clockwise
direction.
•
Check the rotor for firm seating.
Check the firm seating of the rotor on a weekly basis.
•
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.
