The following table gives typical values for the holding 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.

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.
Especially with heavy loading of the steriliser it is not sufficient to use these typical values without further
tests. Reliable sterilisation requires validation of the individual sterilisation process, e.g. with the aid of
additional temperature probes or by using biological or chemical indicators.
Note:
In sterilisation processes the vent valve on the oven must be closed after the moist
sterilisation load has been dried!
WARNING!
Models SFP 700/800 are fitted with lockable doors. If the user, against
our express warning, enters the steriliser chamber he must first remove
the key and carry it on his person.
