4.2.4 Sample gas pump connection gas lines (optional)
On coolers ordered with attached sample gas pump these are already installed and wired. Add-on parts ordered at the same
time are already installed and connected to the sample gas pump.
The sample gas pump may be installed both below and next to the cooler.
Avoid mixed-material installation, i.e. metal piping to plastic bodies. If this cannot be avoided in isolated applications, screw the
metal connections into the pump body with care, never use force.
Lay the lines so the line at the inlet and outlet remains flexible for an adequate distance.
The pumps are marked
IN
for inlet and
OUT
for outlet at the mounting ring. Be sure the gas line connections are tight.
4.2.5 Peristaltic pump connector (optional)
Coolers ordered with attached peristaltic pump already have it installed and wired. Heat exchangers ordered at the same time
are already installed and connected to the peristaltic pump.
The ø6 mm (0.24 inch) hose nipple for the pump’s condensate outlet must be carefully and properly connected with a suitable
hose and hose clamp.
Versions with screw connections DN 4/6 or 1/6”-1/4” are supplied with ferrule and knurled nut and must be carefully sealed
with appropriate hose.

4.2.6 Connecting the heat exchanger
The picture on the left shows the schematics for connecting two separate heat exchangers.
To minimise gas wash out in the cooler, the two (identical) heat exchangers must be operated in series (right picture). This
should be done as follows:
1.
Gas inlet line to red gas inlet on heat exchanger 2 (pre-cooling).
2.
Connection between gas outlet on heat exchanger 2 and the red gas inlet on heat exchanger 1 (after-cooling).
3.
Attaching the final gas output line to the gas outlet on heat exchanger 1.
