5.5.5 Continuous cooling
Continuous cooling
Continuous cooling maintains the rotor chamber at the set temperature if the rotor stops.
During continuous cooling the display shows the set temperature.
To prevent the rotor chamber from freezing or condensation from forming, the temperature does not go
below 4 °C , irrespective of the set temperature.
If the rotor stops, temperature control is slower than during centrifugation or a temperature control run.
ECO shut-off
Continuous cooling is switched off if the centrifuge is not used for longer than the preset time. The
centrifuge switches to standby mode.
Default setting: Continuous cooling ends after 8 h.
Continuous cooling can be limited to 1 h, 2 h or 4 h.
ECO shut-off can be switched off (continuous cooling set to endless operation).
Limit continuous cooling to 1 h (2 h, 4 h).
