Mechanical Emergency Door Release
During a power failure, you will not be able to open the centrifuge door with the regular electric door
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 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 door).
2. Pull out the power supply plug.
3. Unlock the front door by means of square box wrench.
4. Open the front door.
5. Pull down both levers on the right hand side.
The door lock is released mechanically. The door will open and the samples can be removed.

6. Close the front door and lock it well.
Reconnect the centrifuge once the power has been restored. Switch on the centrifuge. Press the key
to have the door locks operative again.
WARNING Never use your hand or other tools to brake the rotor. The rotor can still be
spinning at high speed. If touched, it can cause serious injuries.
