14 SUPPLY CONNECTIONS
14.1 CONNECTING THE HEATED SAMPLE LINE

Remove the aluminium heat-conducting jaws at the probe's filter head by loosening the 4
screws from the gas outlet's threaded connection. The outlet's threaded connection is provided
for the connection of a tube with an external diameter of 6 mm (optionally 8 mm).

Before connecting a sample line not specified by M&C, the tube connection should be
prepared according to the following sketch.
M&C's heated sample lines type PSP 4M4/6 and PSP-W4M4/6 are manufactured to fit the
mechanical and electrical connections to the PSP4000-H... gas sample probe and already contain an
internal line for the probe's power supply.

Connection of the heated sample line

Push the insert into the PTFE tube in order to avoid the tube being compressed and slide the
red silicon protective ring up to the end of the heated sampling tube.

Introduce the PTFE tube into the threaded connection joint with the double-cutting ring system
to ensure sealing.
