The total sterilisation time to be selected consists of the heating-up time (i.e. the time until the desired
temperature has been established within the entire steriliser chamber), the actual sterilisation time, and a
safety margin.
The following table gives typical values for the total sterilisation time to be set, with different amounts
of load, for sterilisers with and without fan. Please note that these values can be employed only with
correct and loose distribution of the load. Notes on the correct loading of the steriliser can be found in
these Operating Instructions and also on the label affixed to the steriliser. In case of unfavourable loading
heating-up time could increase considerably.

The sterilisation time is increased by a factor of 4 when sterilising at a temperature of 160°C.
On large sterilisers and with heavy loading it is recommended to use wire shelves (special accessory) instead
of perforated shelves.
