Maintenance - IKA C 7000 Operating Instructions Manual

3DJH 
When handling combustion samples, combustion residues and auxiliary materials,
the appropriate safety requirements must be observed. The following are examples
of substances that may cause dangers:
2[\JHQ
When working with oxygen, observe the appropriate requirements.
Danger warning: As a compressed gas, oxygen promotes combustion, supports
combustion intensively and may react violently with combustible substances.
'R QRW XVH DQ\ RLO RU JUHDVH
Keep all gas lines and screw connections that carry oxygen free from grease.
Observe the accident prevention requirements applicable to the activity and the
work station.
Close the main valve on the oxygen supply when work is complete.
Only carry out maintenance work when the system is depressurised.

When using crucibles made of stainless steel, their condition should be carefully
PDGH RI VWDLQ
checked after every experiment.
OHVV VWHHO
A reduction in the thickness of the material may cause the crucible to burn and may
damage the decomposition vessel. For reasons of safety, crucibles must not be
used any more after a maximum of 25 combustion procedures.

The decomposition vessel C 7010 and C 7012 are manufactured in accordance with
WKH GHFRPSRVL SRVH the regulation for pressure vessels 97/ 23/ EC. This can be recognized from the &(
WLRQ YHVVHO
V\PERO with the identifying number of the testing station named. The decomposition
vessel is a pressure device of Category III. The decomposition vessel has been
subjected to an EC prototype test. The CE declaration of conformity represents our
guarantee to you that this decomposition vessel complies with the pressure device
described in the EC prototype test certificate. The decomposition vessel has been
subjected to a pressure test at a test pressure of  EDU and a leak test with oxy-
gen at 30 bar.
Decomposition vessels are H[SHULPHQW DXWRFODYHV and must be tested by a SUR
IHVVLRQDOO\ WUDLQHG SHUVRQ each time before they are used.
An individual application is understood here to mean a series of experiments that
are performed under roughly the same conditions in terms of pressure and tem-
perature Experiment autoclaves must be operated in special chambers (C 7000).
5HSHDWHG WHVWV
The decomposition vessel must be subject to repeated tests (internal tests and
pressure tests) by a person with professional training. The intervals between tests
must be determined by the operator based on experience, operating manner and
the material used in the decomposition vessel.

The WKUHDGLQJ on the body of the decomposition vessel and cap screw in particular
are subject to a high level of mechanical stress and must therefore be monitored
regularly for ZHDU DQG WHDU.
The condition of the seals must be checked for functionality must be ensured by
means of a test for leaks (please observe the Operating Instructions for the decom-
position vessel).
Pressure tests and service tasks on the decomposition vessel must only be per-
formed by persons with professional training.
