- INSPECTIONS AND GENERAL MAINTENANCE OF THE
APPLIANCE
Koehler Instrument Co. has reduced the maintenance requirements of the appliance to
the strict minimum. However, in order to ensure reliability of results, it is vital to carry out
basic maintenance of the appliance at regular intervals.
5.1 - Inspections before each test
Before any test, it is mandatory to check:

The condensates container: to avoid any overflow or blocking.
Handling of residues must be done with extreme precaution. These
residues are highly toxic and the operator must be equipped with the
necessary individual protective clothing (gloves, goggles and work
clothes).

The oven outlet must be free of carbon deposits. If this is not the case,
it is recommended running the cleaning cable through to clean off any
deposits (see next paragraph).
5.2 - General maintenance
Depending on the number of analyses and the type of samples used, periodic
maintenance is necessary. The frequency will be adapted to the rate and type of use of
the appliance and must be determined by observation.
5.2.1 Maintenance of the oven
5.2.1.1 Cleaning the cover seal
Air tightness of the oven mouth is by metal-metal contact between the
oven and its cover. Thus it is imperative:

that the cover is free of any shock or impacts

that
the cover and the oven mouth are free of any
carbon deposits.
At the time of manufacture, each oven is paired with
its own cover. A number at the base of the oven
and on the cover allow checking the pairing.

To remove all deposits from the cover and the oven mouth, use wire wool.
Do not
damage the metal.
Do not use emery cloth which would wear away the metal and cause leaks.
