In case of power failure or malfunction, the lid of the centrifuge can be opened manually, in order to

protect samples.

Please proceed as follows (see Figure 30):

• Switch off the centrifuge and unplug the power cord, wait until the rotor has come to a

standstill (this may take several minutes)

• On the left hand side of the centrifuge housing, there is a plastic stopper. Remove this

stopper and behind is a hexagon nut.

• Take the delivered box spanner, put it into the hole, and lock the box spanner, with the

hexagon nut .

• Turn the box spanner to the right (clockwise), up to the limit.

ATTENTION: Only turn to the limit, don´t tighten the nut.

• Open the lid of the centrifuge.

• Switch the centrifuge on again, to proceed with regular function.
