1 Introduction
The Koehler K47001 Autoignition Apparatus is
used to determine the hot and cool flame
autoignition temperatures of a liquid in air at
atmospheric pressure in a uniformly heated
vessel. The temperatures at which ‘cool flame’ and
‘hot flame’ ignitions occur, as evidenced by
sudden temperature increases in the sample flask,
are measured and recorded, and the delay time
between introduction of the sample and ignition is
timed.

recommend consulting the Material Data and
Safety Sheet (MSDS) on each chemical reagent
for additional information. MSDS information can
be easily located on the internet at
http://siri.uvm.edu or http://www.sigma-
aldrich.com.
Disposal. Upon delivery the furnace does not
contain any material which is to be classified as
hazardous waste. However, process residues
may collect in the insulation during operation.
These may be dangerous to health and/or
dangerous to the environment.
Therefore we recommend proceeding as follows:
•Remove electrical components and dispose of
as electrical waste.
•Remove insulation and dispose of as special/
hazardous waste (wear a protective mask P2,
protective gloves and a protective suit).
•Dispose of the housing as scrap metal
3 Getting Started
The instructions for preparing the equipment
assume that the user is aware of the contents of
this document, which lists the warranty conditions
and important precautions.
3.1 Unpacking
Carefully unpack and place the instrument and
accessories in a secure location. Ensure that all
parts listed on the packing list are present. Inspect
the unit and all accessories for damage. If any
damage is found, keep all packing materials and
immediately report the damage to the carrier. We
will assist you with your claim, if requested. When
submitting a claim for shipping damage, request
that the carrier inspect the shipping container and
equipment. Do not return goods to Koehler without
written authorization.
3.2 Setup
3.2.1 Installation Site
Place the furnace on a non-flammable support
(stone, metal or similar). Keep a safe distance
from flammable components, 0.5 m from the
furnace sides and 1 m from the top. The minimum
distance between the furnace sides and non-
flammable materials can be reduced to 0.2 m.
Ventilation. Provide sufficient room ventilation to
carry off exhaust heat and gases which develop
during the process. Non-observance can result in
a fire risk and danger to health.

3.2.2 Electrical Connection
•Attach the correct plug to the power supply
cord(s) and connect the main plug in a
corresponding receptacle which is protected
sufficiently depending on the rated power of
the furnace. If the furnace is ordered /
delivered without a plug, a qualified electrician
must connect the furnace.
•NOTE: Using extension cables and/or junction
boxes may lead to a reduced furnace output
due to the voltage drop in the lines. The
power is also reduced if the connection line to
the junction box is very long, and the furnace
will not reach its nominal temperature. Please
have the connection checked by an
electrician. The voltage may not drop below
the rated load by more than 10%.
WARNING: For safety, disconnect the power
when performing any maintenance and/or
cleaning.
3.2.3 Initial Heating Procedure
•To dry out the brick lining and to create an
oxide protection layer on the resistance wire,
an initial heat run must be performed prior to
testing. This may cause an unpleasant smell.
Provide sufficient ventilation.
•Heat the empty furnace up to 1050 ºC over the
course of six hours. At each change rise in
temperature, run the AUTO TUNE on the
tuning page. Once 1050 °C is reached,
maintain this temperature for one hour, and
then let the furnace cool down on its own.
•The furnace is now ready to operate.

5 Operation
5.1 General Notes
•The insulation consists of high-quality
refractory material which is susceptible to
shock. Take care not to knock against the
refractory material when charging the furnace
to avoid damage.
•In order to achieve an even temperature
distribution the furnace should be charged in
such a way that products have a certain
distance to each other and also to the side
walls. Koehler offers shelves, etc. so that the
furnace chamber can be used in the most
efficient way possible.
•If the furnace is charged with a high quantity
of products the heating time may be prolonged
considerably.
•The furnace heating is stopped when the door
is opened and is switched on automatically
when the door is closed.
•Do not open the furnace when it is hot. If the
furnace must be opened at high temperatures
do this as quickly as possible. Wear personal
protective equipment and clothing and provide
sufficient room ventilation.
•Make sure that the door is properly closed
during heating.
•Discolorations may occur on the stainless
steel housing (especially when the hot furnace
is opened); these, however, do not affect the
functionality of the oven.
5.2 Maintenance and fault clearance
Regularly clean the ventilation holes/pipes so that
the ventilation cross-section remains unobstructed
and the suction functions well.
In the case of commercial use:
Please observe the safety regulations
applicable to your country.
When ordering replacement part(s), please
provide the model number, serial number, and
product shipment date of your equipment so that
we can ensure you will receive the proper
replacement part(s).
