14 CLOSING DOWN
N O T E !
The location for the gas conditioning unit must remain frost-free, even if the
unit has been switched off.
There are no special regulations to be observed if the gas conditioning unit CSS-V is to be closed
down for a short period of time.
In case of a long-term closing down, for example after a series of measurements has been completed,
it is recommended to purge the gas conditioning system with ambient air or inert gas. Under normal
conditions, the equipment needs only to be washed for 3 to 5 minutes. Condensate residues should
also be removed from the system.
W A R N I N G !
Aggressive condensate possible.
Wear protective glasses and proper protective clothing!
15 MAINTENANCE
Before carrying out any maintenance work, the specific safety instructions referring to the instalment
and the process must be observed!
W A R N I N G !
Dangerous voltage. Before any maintenance work is carried out on
the gas conditioning system, disconnect the unit from the mains !
The frequency of the maintenance work depends on the operational process and can therefore only
be determined in each individual case.
All parts which require maintenance work are easily accessible and are installed on the front side of
the gas conditioning unit CSS-V. Only for any work on the gas sample pump, the case has to be
opened:

Replace the filter element of the fine filter FPF-2-0,3 GF in case the flow rate is to low or after
visible control (see chapter 15.1).
N O T E !
In order to protect downstream analysers in case of a irruption of
condensate, always replace the humid filter element.

The diaphragm of the sample gas pump N3/5/9 KPE should be checked every six months and, if
necessary, replaced (see chapter 15.2).
