Installation And Removal Of The Rotor; Loading The Rotor - Hettich ROTO SILENTA 630 RS Bedienungsanleitung

Installation and removal of the rotor


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
A
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.

Loading the rotor

Standard centrifuge containers of glass will not stand RCF values exceeding 4000 (DIN 58970, pg. 2).

Check the rotor for firm seating.

With swing-out rotors all rotor positions must be lined with identical hangers. Certain hangers are marked with
the number of the rotor position. These hangers may only be used in the respective rotor position. Hangers that
are marked with a set number (e.g. S001/4) may only be used in the set.

The rotors and hangers may only be loaded symmetrically. The centrifuge containers have to be distributed
evenly on all rotor positions. For authorised combinations see Chapter "Anhang/Appendix, Rotoren und
Zubehör/Rotors and accessories".
In the case of angle rotors all possible rotor positions must be loaded, see chapter "Anhang/Appendix, Rotoren
und Zubehör/Rotors and accessories".
Rotor is evenly loaded

On certain hangers, the weight of the maximum load or the weight of the maximum load and the maximum
weight of the completely loaded hanger is specified. This weight may not be exceeded. In case of exception, see
chapter " Centrifugation of materials or mixtures of materials with a density higher than 1.2 kg/dm
specified for the maximum loading includes the total weight of adapter, frame, centrifuging container and content.

In containers with rubber inserts, the same number of rubber inserts must always be among the centrifuge
containers.

The centrifuge containers may only be filled outside of the centrifuge.

The maximum filling quantity for the centrifuge containers specified by the manufacturer must not be exceeded.
In the case of angle rotors, the centrifuging
vessels may only be filled so far that no fluid
can be expelled from them while the centrifuge
is running.

When loading the angle rotors, no liquid may get into the angle rotors or centrifuging chamber.

When loading the hangers and swing-out rotors and when swivelling out the hangers while the centrifuge is
running, no liquid may enter the hangers or the centrifuging chamber.

In order to maintain the weight differences within the centrifuge container as marginal as possible, a consistent
fill level in the containers is to be heeded.
