Manual Door Release
During a power failure, you will not be able to open the centrifuge door with the regular electric
centrifuge 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 deceleration process lasts much longer than usual.
Proceed as follows:
1. Wait until the rotor has stopped. This might take some 60 minutes or even longer.
2. Pull out the power supply plug.
3. On the left side of the housing are two white plastic plugs which you can pry out of the side plate
with a screwdriver or a knife.
Pull the release cords attached to it at the same time to trigger the mechanical centrifuge door
release. The centrifuge door will open and the samples can be removed.
