5.2.3 Installation of Rotors
• Open the centrifuge lid by pressing the lid key.
• Unscrew the rotor tie-down screw from the motor shaft (anti-clockwise).
• Lower the rotor with its central bore straight down onto the motor shaft.
• Tighten the rotor tie-down screw clockwise with the supplied rotor wrench
with 5 Nm. In doing so, hold the rotor at its outer rim.
• After frequent use, the rotor tie-down screw must be loosened by some turns
and fastened again. This must be done once a day or after 20 cycles. This
ensures a proper connection between the rotor and the motor shaft.
• The rotor tie-down screw should only be tightened when a rotor is installed in
order to prevent the collet chuck from being expanded.
) Attention!
• When using rotors for microtiter plate formats: Ensure that the plate holders
are inserted together
with the plates into the buckets.
• The lid screw serves for the fastening of the lid onto the rotor only, not for the
fastening of the rotor onto the collet chuck. Prior to installing the lid, check for
the tight fit (5 Nm) of the rotor tie-down screw.
) Attention!
• Please follow the safety instructions and hazard warnings in chapter
