Mechanical Emergency Door Release
During a power failure, you will not be able to open the centrifuge lid with the regular electric lid
release. A mechanical override is provided to allow sample recovery in the case of an emergency.
However, this should be used only in emergencies and after the rotor has come to a complete stop.
Always wait a few minutes until the rotor has come to a stop without braking. The brake does not work
when there is no current. The braking process lasts much longer than usual.
Proceed as follows:
1. Make sure the rotor has stopped (view port in the lid).
2. Pull out the power supply plug.
3. On the back of the housing are two black plastic plugs which you can pry out of the back plate
with a screwdriver or a knife.
Pull the release cord attached to it at the same time to trigger the mechanical lid release. The lid
will open and the samples can be removed.

4. Push the cord back into the centrifuge and mount the plug.
WARNING
The rotor can still be spinning at high speed. If touched, it can cause serious
injuries.
WARNING
Never use your hand or other tools to brake the rotor.
Note
You need to pull both levers in order to unlock both locks.
