Centrifuge 5424 / 5424 R — Operating manual
6.3 Additional service instructions for Centrifuge 5424 R
 Empty and clean the condensation water tray regularly and especially after liquid spillage in
the rotor chamber. Pull out the tray for condensation water from the left side of the centrifuge.
 Clear the rotor chamber regularly of ice formations by thawing, either by leaving the centrifuge
lid open or carrying out a brief temperature control run at approx. 30 °C.
 Wipe up condensate in the rotor chamber. To do so, use a soft absorbent cloth.
 Remove dust deposits from the ventilation slits of the centrifuge using a brush or swab at the
latest every six months. First switch off the device and remove the power plug.
6.4 Glass breakage
Broken glass scratches the surfaces of the rotor chamber and the accessories (Rotors, rotor lid
and adapter) so that their chemical resistance is reduced. Therefore, a fine, black metal abrasion
develops in the rotor chamber due to the air turbulence which, in addition to causing damage to
the rotor chamber and the accessories, can also contaminate the samples.
 Carefully remove all splinters and glass powder from the rotor chamber and accessories
when breakage of glass occurs (Rotors, rotor lid and adapter).
 If required, replace the adapters to prevent any further damage.
 Check rotor bores regularly for residues or damage.
6.5 Fuses
The fuse holder is located under the mains power socket (5424) (Fig. 1 on p. 8) or on the right
next to the mains switch (5424 R) (Fig. 2 on p. 8).
1. Disconnect the mains plug.
2. Remove the fuse holder.
Both fuses are now accessible and can be replaced.
6.6 Decontamination before shipping
If you are shipping the device to the authorized Technical Service for repairs or to your authorized
dealer for disposal please note the following:
Hint!
Note when using glass tubes that the danger of breakage of glass increases with an increasing
g-force (rcf) or speed (rpm). Please note the manufacturer's information on the recommended
centrifugation parameters (loading and speed).
WARNING!
Risk to health from contaminated device.
1. Follow the instructions in the decontamination certificate. This can be found in a PDF file on
our homepage (www.eppendorf.com/decontamination).
2. Decontaminate all the parts you want to dispatch.
3. Enclose the fully-completed decontamination certificate for returned goods (incl. the serial
number of the device) with the dispatch.
