As described below, the defrost function operates differently depending on centrifuge status when
defrosting is started. Evacuation is performed simultaneously with defrosting.

Operation
details
Defrosting starts when selected and
continues for 10 minutes. When
defrosting ends, the air leak valve
automatically activates.
If the vacuum pump is not operating, it will
start operating when the defrost function
is selected. When defrosting ends, the
vacuum pump stops operating and the air
leak valve is activated to vent the
Defrosting starts when rotor speed starts
to decelerate and continues for 10
minutes.
After defrosting ends, the temperature is
controlled until the air leak valve
activates and the chamber is vented.
Canceling
Press the [VACUUM] button to activate
the air leak valve and stop defrosting.
Press the [DEFROST] button from the
“MENU” tab and select [Normal].
1) Be sure to close the door when defrosting is started after the rotor has stopped.
2) Wipe the rotor chamber dry if there is plenty of moisture.
3) Enabling the defrost function when the rotor is turning starts defrosting when the rotor
decelerates. Then the bowl is heated for 10 minutes and evacuation continues. Regardless
of whether the rotor is still rotating or has stopped after 10 minutes, temperature control will
resume if the [VACUUM] button is On.
If the defrost function is enabled, set the [VACUUM] button to Off as soon as the rotor stops
and remove the rotor.
4) When defrosting is enabled in zonal operation, defrosting starts when the rotor decelerates.
When defrosting ends after 10 minutes, temperature control resumes unless the air leak
valve is activated and the chamber is vented.
5) The temperature rise caused by the defrosting operation (10 minutes) is less than 1°C.
