Install the rotor carefully and securely on the drive shaft (crown) in the rotor chamber�
Always place the rotor pin in the drive hole (crown hole) next to the crown pin�
Take care not to get your hands or fingers caught in the door of the centrifuge�
Maximum rotor speed depends on the tubes or adapters to be used� Follow the
instructions in the rotor instruction manual�
Sufficient balance can be achieved by placing approximately equivalent quantities of
sample in the tubes; extreme differences in sample quantity must be avoided�
Clean the inside of the drive hole (crown hole) of the rotor and the surface of the drive
shaft (crown) of the centrifuge once a month�
Storing the rotor on a shelf is permitted if the shelf provides adequate earthquake
protection to prevent the rotor from falling�
Do not pour any solution such as water, detergent or disinfectant directly into the rotor
chamber� Take care to prevent leakage of the sample� Failure to comply with this may result
in corrosion or deterioration of the bearings of the drive unit and/or the sensors�
Use the rotor log book to manage the life of the rotor�
It is important to manage the life of the rotor� The life of each rotor is unique and is
dependent upon the frequency of use and the total running time� Do not use rotors whose
service lifetime has been exceeded� If such an instrument it used, it can incur serious
damage� (Comply with the rotor instruction manual�)
For details on zonal centrifugation, see the zonal rotor instruction manual�
Do not press the touchscreen with a sharp-pointed object such as a ballpoint pen�
Make sure to remove the rotor from the rotor chamber when the centrifuge is not in use
over a long period or when the instrument is moved� Otherwise the drive shaft (crown) may
be damaged�
To avoid electrical shock hazards, proceed as below when servicing the centrifuge�
Make sure to turn off the POWER switch and, if your centrifuge is equipped with a three-
wire power cord, turn off the distribution board of your centrifuge room� Then wait at least
three minutes before removing the covers from the centrifuge�
Make sure to turn off the POWER switch and, if your centrifuge is equipped with a power
cord with plug, unplug the power cord from the outlet� Then wait at least three minutes
before removing the covers from the centrifuge�
When a power failure occurs during operation, it takes three hours or more for the moving
rotor to stop completely because the rotor chamber is depressurized and thus contains
less air to brake the rotor� Make sure to allow sufficient time to elapse before opening the
door of the rotor chamber�
For maintenance and repair work on the rotors, tubes, etc�, refer to the rotor instruction
manual and the rotor, tube, bottle, and cap instruction manual�
After installation and before any test run is performed, this ultracentrifuge requires an
internal check by an authorized Thermo Fisher Scientific sales/service representative�
Repairs, disassembly, and other modifications to the centrifuge are strictly prohibited
unless performed by an authorized Thermo Fisher Scientific sales/service representative�
