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).
1. Press the menu/enter key.
2. Select TEMP using the arrow key. Confirm with the menu/enter key.
3. Select 1 h ( 2 h, 4 h ) using the arrow key. Confirm with the menu/enter key.
4. To activate ECO shut-off after 1 h, 2 h or 4 h, open and close again the centrifuge lid after the end of the
run.
The device switches to standby mode after 1 h, 2 h or 4 h. The display shows EP .
5.5.6 Endless operation of continuous cooling
The ECO shut-off function can be switched off. Continuous cooling is changed to endless operation.
• Endless operation can shorten the service life of the compressor.
• The rotor chamber may freeze.
1. Press the menu/enter key.
2. Select TEMP using the arrow key. Confirm with the menu/enter key.
3. Select oo using the arrow key. Confirm with the menu/enter key.
Ending continuous cooling
4. Open the centrifuge lid to end continuous cooling.
• If the centrifuge lid is not opened and closed again after the run, ECO shut-off engages
after 8 h (default setting).
• Open the centrifuge lid to end continuous cooling early.
