Installation
Manual Lid Unlocking
Procedure
• Put the rotor on the motor shaft
• Secure the rotor on the shaft by turning the hexagonal nut counter-
clockwise (with the supplied tool)
• Verify that the rotor cannot be removed by trying to pull it (gently)
off the shaft.
• In case you are using a swing-out rotor:
• Gently grease the trunnions
• Put the buckets on the trunnions after verifying that the weight of
the buckets is identical (the weight is engraved on the bottom of
each bucket).
In the event of mains non-availability or power failure, opening of the
lid is prevented by the lid locking safety device. It is recommended that
the user waits for the mains to be switched back on so that this safety
device enables the lid to be unlocked.
Manual lid unlocking must only be done by someone informed of
the possible danger and of the necessary precautions.
Rotating parts are a risk as they could come in contact with the user or
be ejected. There is particularly high risk of injury if:
• The user attempts to manually stop the rotor
• Any object falls inside the centrifugation chamber while the rotor is
running.
L
Manual lid unlocking may be necessary under a very limited number
of conditions, such as the urgent recovery of critical samples that could
be damaged if left in the centrifuge rotor.
In this case the lid can be opened by using the special tool supplied
with the centrifuge.
Always set the power switch to the OFF position before performing
this manual procedure, even in the case of a mains power outage.
L
Should the emergency occur due to power failure during centrifugation
wait at least 10 minutes for the end of the rotor rotation. In spite of
the absence of noise, the rotor could still be rotating when you need to
open the lid manually. Upon opening, lift the lid by hand and observe
the rotor (be careful in this operation): if it is still rotating, close the lid
and wait.
