9. Connect the measuring cell to the outlet.
If a sample return pump is present, then
use the connecting pipe (see figure below).
Section 2.3
The connection of the sample
return is dependent on the installed
components. The following options
are available:

Direct connection to the dis-
charge system

Direct connection to the op-
tional sample return pump

Through the optional sampling
equipment
10. a) Connect the compressed air line on systems
with optional pumps.
The compressed air line is adjusted at the
factory according to the components present
and installed. The purging air for the Ex hous-
ing and compressed air for the pump are fed
from the same source.
The compressed air is also used as purg-
ing air and should thus be clean, dry and
oil-free (instrument air, ISO 8573-1:2010
[1:3:1]).
A: Reducing valve for purging air on the Ex
housing
B: Compressed air connection for sample feed
pump
C: Main purging air/compressed air connection
D: Compressed air connection for sample re-
turn pump
b) Connect the compressed air line on instru-
ments without pumps.
Only carry out steps 1 and 2 if a free-fall
measuring cell KPFLJC PVDF is present.
1. Connect the purging air line to the measur-
ing cell KPFLJC PVDF (pos. B).
2. Connect the purging air line on the pressure
regulator side (pos. A).
3. Connect the compressed air/purging air to
the fittings (circle).
