Emergency release

During a power failure the lid cannot be unlocked by motor. An emergency release has to be executed by hand.
For emergency release disconnect the centrifuge from the mains. In the case of permanently connected
devices, switch off the mains switch to disconnect the mains supply of the device in the building installation
and secure it against being switched on again, e.g. by locking the switch.
Open the lid only during rotor standstill.
See figure on page 2.

Switch off the switch on the front panel (switch position "0").

Look through the window in the lid to be sure that the rotor has come to a standstill.

Insert the hexagon socket head wrench horizontally into the drilling (Fig. 1, A) and carefully rotate by half a turn
in clockwise direction until the lid can be opened.

Pull the hexagon socket head wrench out of the drilling again.

After turning the centrifuge on again, press the button
the normal position (opened).
