1.2 Product safety and dangers
The appliances described in this manual are technically sophisticated, manufactured using
high-quality materials and subject to many hours of testing in the factory. They contain the
latest technology and comply with recognised technical safety regulations. However, there are
still risks involved, even when the appliances are used as intended. These are described below.
Warning!
After removing covers, live parts may be exposed. You may receive
an electric shock if you touch these parts. Disconnect the mains plug
before removing any covers. Only electrical technicians may work on
the electrical equipment of the appliances.
Warning!
When loading the appliance with an unsuitable load, poisonous
or explosive vapours or gases may be produced. This could cause
the appliance to explode, and persons could be severely injured or
poisoned. The appliance may only be loaded with materials/test

2.2 Function
Appliances of the UN, SN and
IN type series feature
natural circulation
(convection). For the UF, SF
and IF type series, air is
circulated by a fan at the
working chamber rear panel
(Fig. 3 , No. 1). It increases
the air flow and provides
stronger horizontal forced
air circulation than natural
convection.
In both the convection and
fan ventilated appliances,
supply air (2) is preheated
in a pre-heating chamber
(3). Through the ventilation
slits in the side panel of
the working chamber, the
preheated air is introduced
into the interior of the
chamber. The supply and
exhaust air (5) volume (air
change) is controlled by the
air flap (4) on the rear panel
of the appliance.

3. Press the confirmation key. The display
now shows the remaining time in a large
font and the approximate end time in a
smaller font beneath.
4. Now, as described under 5.4.2, set the individual values for temperature, air flap position
etc. which you want the appliance to operate at. For universal ovens UN/UF and incubators
IN/IF, the set values can be changed while the timer elapses. The changes are effective immediately. For sterilisers SN/SF, parameters cannot be changed while the timer elapses.
For universal ovens UN/UF and incubators IN/IF, you can choose if the timer should run
setpoint-dependent or not in the
until a tolerance band around the set temperature is reached or if it should start right after
activation (see page 35). If the timer runs setpoint-dependent, this is indicated by the
symbol in the timer display.
When the timer has elapsed, the display shows 00:00. All functions
(heating etc.) are switched off. If a fan had been active, it will keep
on running for a short safety period.

For sterilisers SN/SF, the timer is by default setpoint-dependent. To ensure that the
required temperature is maintained for a sufficient period of time, this setting cannot be
changed. If the temperature is no longer within the tolerance band, the sterilisation time
is, for reasons of safety, restarted as soon as the required temperature is reached again.
For universal ovens UN/UF and incubators IN/IF, the timer is in this case interrupted and

Sterilisers SF/SN
8. Sterilisers SF/SN
8.1 Intended use
The SF/SN appliance serves for sterilising medical material through dry heated air at
atmospheric pressure.
8.2 Note in accordance with Medical Devices Directive
The product lifetime as intended by the manufacturer is eight years.
8.3 Guidelines for sterilisation
For hot air sterilisation, there are different guidelines on the temperature and sterilisation
time to choose, as well as on packaging the sterilisation load. The values to be chosen depend
on the type and characteristics of the load to be sterilised and on the type of germs to be
neutralised. Before beginning sterilisation, make yourself familiar with the sterilisation method
laid down for your application.
Process parameters for hot air sterilisers are temperature and minimum hold time. The
following process parameters have been defined in recognised standards:
► According to WHO: 180 °C with a minimum hold time of 30 min► According to the European Pharmacopoeia: 160 °C with a minimum hold time of 120 min
For the inactivation of endotoxin (pyrogenes), dry heat of at least 180 °C can be applied. For
the depletion of pyrogenic substances, you have to keep a combination of temperature and
time going beyond the requirements of sterilisation.
Inactivation of endotoxin is possible using the following process parameters (data in
accordance with ISO 20857:2010):
► 180 °C with a minimum effective time of 180 min► 250 °C with a minimum effective time of 30 min
Caution:
The temperature and time requirements normal for hot air sterilisation do not destroy
endotoxins.
Especially when the appliance is heavily loaded, using these parameters without checking
them will not be sufficient. For safe sterilisation, validation of the individual sterilisation
process is required. The requirements for the validation of sterilisation by dry heat are e.g.
defined in standard ISO 20857:2010. Also valuable is the "guideline on validation and routine
monitoring of sterilisation processes using dry heat for medical products" issued by the
German Society for Hospital Hygiene (DGKH).
