The resulting condensate is continuously discharged by a peristaltic pump type SR25.1 .
A pre-filter type PF2  is installed in the condensate line between the heat exchanger and the
peristaltic pump. This protects the pump from particle contamination in the condensate.
The 4/6 mm tube connections for the condensate and sample gas lines are located on the right
11
side of the case (see Figure 2 and Figure 5).
A stainless steel sample tube (length 0.5 m, Ø 6 mm) and 3 m PVC sample tubing (4/6 mm) are
included as standard.
The ventilation grids in the lid and in the left side wall of the case provide sufficient convex forced
ventilation.
Options:
The PSS-5 and PSS-5/3 sample gas conditioning unit can be equipped at the factory with a maximum
of four sample gas outlets. Each sample gas outlet can be controlled according to the specified volume
flow range (see table on page 9) by the optional installation of a flow meter type FM40 with needle
valve. Unused mounting holes for sample gas outputs or flow meters are closed by blind caps.
To protect the downstream analyzers against liquid ingress and to increase the operational reliability
of the entire system, we recommend the installation of a liquid alarm sensor type LA1S. For this
purpose, the FP-2T fine filter installed as standard is replaced at the factory by the FP-2T-D fine filter
with built-in liquid alarm sensor. The LA1.4 electronic controller is located on the terminal support rail
 (Figure 2), in the upper part of the case. The LA electronics automatically shuts off the sample gas
pump in the event of a liquid alarm. The alarm is indicated by a red LED. If there is no alarm, a green
LED will be on.
The PSS-5 and PSS-5/3 sample gas conditioning units can optionally be equipped with a sample gas
inlet (see Figure 3, Part No. 01G9060) for connecting a heated sample line. The existing anti-kink
protection must only be used for heated sample lines of connection type "C" (Part No. 03B1012).
Assembly instructions can be found in the appendix.
It is also possible to connect the heated sample line Part No. 01B4036 in connection with the gas
sample probe PSP 4000.
The temperature controller 701 (Part No. 01G9055) required to control the heated line is factory-
installed on the terminal support rail  (Figure 2).
A 3-way ball valve (Part No. 01G9046) or a 5-way ball valve (Part No. 01G9045) can optionally be
installed in the inlet of the gas conditioning unit for test gas feed or sample gas switching.
