Figure 20: Mounting brackets
A
Do not squeeze the heat insulation in mounting brackets
tightly together, so that the outer braiding is pressed on to
the heat conductor. If you disregard this, damage to the
protective braiding and the heated sample gas line may
occur.
B
Tighten the BBS cable clips sufficiently but not excessively, in
order to prevent damage to the protective braiding and the
heated sample gas line.

Figure 21: Connecting the back purging unit
1. Mount the solenoid valves on the filter unit as illustrated.
2. Connect the compressed-air pipes for purge air and control
air to the respective ports at the filter unit.
3. Connect the electrical cables of the solenoid valves to the
corresponding terminal strip in the analyzer cabinet. For
