temperature, 4 °C must be met via this continuous cooling in order to prevent the rotor chamber
from freezing.
5.3.5 Continuous cooling
If the rotor stops, the rotor chamber will be maintained at the target temperature if the following
requirements have been met:
• The centrifuge is switched on.
• The centrifuge lid is closed.
• The target temperature is lower than the ambient temperature.
• The centrifuge is not in standby mode.
During continuous cooling the following applies:
• The set and actual temperature are displayed alternately.
• Irrespective of the set temperature, the temperature does not go below 4 °C to prevent the
rotor chamber from freezing and from increased condensation in the device.
• The temperature adjustment is slower because the rotor does not rotate during this process.
To end continuous cooling, open the centrifuge lid or press the standby key.
If the centrifuge is not used for more than 8 hours, the continuous cooling is switched off
automatically (ECO shut-off). The device then switches to standby mode. This protects against
ice formation in the rotor chamber and increased condensation in the device. With FastTemp you
can quickly reach the desired temperature again (see p. 55).
You can also change from automatically switching off continuous cooling after 8 hours (ECO
shut-off) to unlimited continuous cooling.
1. When the centrifuge lid is opened, press the temp and prog keys simultaneously.
Standby 8h appears in the display.
2. Press the fast temp key immediately.
Endless operation for continuous cooling is activated. Standby endless appears in the
display.
3. To change back to Standby 8h , repeat the process.
Hint!
The centrifuge stops the cycle automatically if the rotor or the buckets have reached the set
temperature. Therefore, there may be a delay of approx. 30 min between the display of the set
temperature and the automatic end of the temperature control run.
Hint!
When using aerosol-tight buckets, always carry out a FastTemp run at low temperatures without
a cap. There is a danger otherwise of the caps becoming fixed by suction due to a vacuum. Do
not pull on the sealing clamps or hooks to loosen the cap. Adjust the temperature of the buckets
to room temperature so that the caps can be removed easily.
NOTICE!
Ice formation and compressor overheating during continuous cooling.
 Switch the centrifuge off regularly to eliminate any ice formation by thawing.
 Regularly remove condensation from the rotor chamber using a soft, absorbent cloth.
 Empty and clean the condensation water tray regularly.
