Precooling the centrifuge (20R refrigerated models only)
To maintain sample integrity during low temperature runs it is recommended to precool the empty
rotor and instrument prior to the run. This centrifuge has a special program that precools the
centrifuge under defined conditions.
NOTE
Once the precooling program is loaded, the set temperature can only be set to values below the actual
temperature. If the limits of the setting range are reached during the setting process, the temperature
display flashes for approximately one second.

The display shows 1/3 of the maximum rotor speed and the corresponding RCF value. The
runtime field indicates ‘

’ (continuous run). The set temperature cannot be higher than the
actual temperature.
