6.2.2.2
Installation of Angle Rotors with a Hermetically Sealed Lid
Screw the rotor cover onto the rotor and tighten it.
Lower the rotor with the cover onto the motor shaft .
Insert the rotor tie-down screw into the motor shaft. Tighten the
rotor tie-down screw with 10 Nm using the supplied rotor wrench
so that the spring washer assembly is compressed tightly.
The rotor can also be used without a cover.
Slightly grease the rotor and lid seals after cleaning.
The rotors can be installed or removed with a closed lid after
loosening the rotor tie-down screw.
Follow the safety instructions and hazard warnings in chapter 3!

6.2.2.3 Installation of Accessories
Only use inserts that are suitable for the rotor (see 11.1 "Suitable
Accessories").
All four buckets of the swing-out rotor need to be installed when
spinning.
Always load the opposite inserts/buckets of the rotors with the
same accessories and fill to avoid imbalance.
Centrifugation with different tube sizes:
Working with different tube sizes is possible. In this case, however, it
is very important that opposite inserts are identical (see Fig. 6.2).
Centrifugation with low capacity: The tubes must be installed
symmetrically so that the buckets and their inserts are loaded evenly
(see Fig. 6.3).
