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.
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 Connecting the heat exchanger
To minimise gas wash out in the cooler, the two (identical) heat exchangers must be operated in series. This should be done as
follows:
1.
Gas inlet line to red gas inlet on heat exchanger no. 2 (pre-cooling).
2.
Connection between the heat exchanger no. 2 gas outlet and the red gas inlet on heat exchanger no. 1 (after-cooling).
3.
Secure final gas outlet line to the heat exchanger no. 1 gas outlet.
