19 MAINTENANCE
Before the maintenance work is carried out, it is necessary that the specific safety procedures pertain-
ing to the system and operational process be observed!
W A R N I N G !
Dangerous voltage. It is necessary to take the equipment off the
mains before any assembly, maintenance or repair work is carried
out.
In order to do this the mains plug has to be removed from the
mains plug socket!
The frequency of the maintenance work depends on the operational process and can therefore only be
determined in each individual case. Maintenance instructions pertaining to individual components can
be found in the instruction manual for individual components.
All parts which require maintenance work are housed in the gas conditioning system in such a way so
that they are easily accessible. These are:

The filter element of the preliminary filter FPF-0,1GF.
N O T E !
In order to protect the analysers which have been additionally
connected, it is recommended that in the event of a condensation
irruption the moist filter elements be replaced.

The preliminary filter for the peristaltic pump PF2. If the condensate contains particle residue, the
preliminary filter should be replaced at regular intervals. The ‘one-way’ filter is situated in the suc-
tion side of the pump hose and can be easily replaced;

Hoses of the Condensate pump SR25.1. These should be checked every six months and, if neces-
sary, replaced;

Diaphragm of the sample gas pump N3KPE or N9KPE.. These should be checked every six
months and, if necessary, replaced;
20 DISMOUNTING THE FLOW COMPONENTS SUB PANEL
The dismounting of the flow components sub panel is carried out stepwise as follows:

check if the CSS is disconnected from all power supplies;

loosen the fastening screw from the flow alarm sensor;

remove the sensor from the flow meter glass;

turn the union nut of the liquid alarm sensor left by hand (fix the sensor while loosen the nut);

pull out the sensor of the flow chamber;

unscrew the hose connections of the condensate pump;
