4.2.4 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.

4.2.5 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.

On glass heat exchangers the correct position of the seal is important when connecting the gas lines (see image). The seal con-
sists of a silicone ring with a PTFE sleeve. The PTFE side must face the glass thread.
