Cleaning the system
Refer also to the operating instructions for the C
6010/ 6012 decomposition vessel
For cleaning, disconnect the main
plug!
After the result has been recorded, you can take out the decom-
position vessel, open it and clean it.
If you suspect that the combustion sample, the combustion gases
produced or the combustion residue could be harmful to health,
wear personal protective equipment (e.g. protective gloves, brea-
thing masks) when handling these materials. Harmful or polluting
combustion residue must be disposed of as hazardous waste. Ex-
press reference is made to the applicable regulations.
In order to obtain accurate measurements it is essential that the
decomposition vessel is clean and dry. Impurities alter the heat
capacity of the decomposition vessel and thus cause inaccurate
measuring results. It is important to thoroughly clean the inner
walls of the vessel, the internal fittings (brackets, electrodes etc.)
and the combustion crucible (inside and out!) after each combus-
tion test.
In most cases all that is necessary is to remove condensate from
the inner walls of the vessel and the internal fittings. It is sufficient
to thoroughly wipe the parts with an absorbent, non-fibrous cloth.
If the decomposition vessel cannot be cleaned in the above way
(e.g. due to baking, pitting, corrosion etc.), please contact Tech-
nical Service.
The combustion residue in the crucible, e.g. soot or ashes, should
also be wiped away with an absorbent non-fibrous cloth.
Repairs:
Please only send devices in for repair that have been clea-
ned and are free of materials which might present health
hazards.
For this, use the “ certificate of compliance ” form which you
can obtain from IKA
®
or can download a version for printing from
the IKA
®
website at www.ika.com .
If your appliance requires repair, return it in its original packaging.
Storage packaging is not sufficient when sending the device - also
use appropriate transport packaging.
Servicing and cleaning the filter
Servicing
Check the filter every week or according to experience. Over time
the filter becomes clogged with sludge thereby causing a reduc-
tion in the cooling water flow rate.
Do not use distilled or demineralized water (increased risk
of corrosion)! Fill the cooler according to the cooler operating
instructions. is recommended in drinking tap water quality. Mix in
(max. 1 ml for 4-5 l of water) of the supplied water additive. Thus,
the durability of the water is improved.
Cleaning
• Switch the device off.
• Switch the cooling water supply off (switch off the conden-
ser, clock the water shut-off valve).
• Disconnect the hoses from the device.
• Have an absorbent cloth ready to hand.
• Turn the filter casing anticlockwise, some water will escape.
wipe up the water with the cloth.
• Pull out the sieve.
• Use a suitable brush to clean the sieve inside and out.
• Place the sieve back in the filter.
• Screw the filter casing on again finger-tight.
• Reconnect the hoses to the device (see also the section
“Commissioning“).
• Switch the cooling water supply on again.
• Switch the device on again.
