Emergency Lid Release
In the event of a power supply failure, it is possible to manually open the
centrifuge lid using two stoppers that are secured with screws. They are located
on the front of the bottom panel.
•
Switch off the mains power switch and disconnect the power cord from the
socket.
•
Unscrew the screws in the stoppers.
•
Remove the stopper, e.g. with a screwdriver.
•
Pull the visible strings in order to release the lid. Then, reinsert the stoppers
into the openings.
•
Reinsert the screws centrally.
The lid may only be unlocked and opened when the rotor is at a standstill.
If the lid is opened by way of the emergency lid release during operation, the
centrifuge will be switched off immediately and decelerate brakeless.
