4.2.1 Lid Release during Power Failure (Emergency Lid Release)

In case of power failure or malfunction, the lid of the centrifuge can be opened manually, in order to
protect samples.
Please proceed as follows:
• Switch the centrifuge off and unplug the power cord, wait until the rotor is at a standstill,
(this may take several minutes).
At the right side of the centrifuge, there is a plastic stopper (Figure 35). Remove this stopper, which
is connected to the lid lock, horizontally from the housing until the centrifuge lid opens.
• Now, open the lid of the centrifuge.
