Installation Guide
Connecting the gas lines
Gas lines route gases from the sensor head to the analytical unit. They are made from semi-rigid
stainless steel tubing.
NOTICE
You can connect any of the gas lines to any of the two gas connectors inside the unit.
To connect the gas lines:
1
Stretch out the gas line tubing slightly to bring its tip to a gas connector inside the cabinet.

2 Push the tip slowly but firmly into the connector opening until you feel it make contact at the bottom
of the opening.
3
Tighten the screw by hand as much as possible.
4
Once tightness has been achieved, apply a final 1/8 to ¼ turn (45° to 90°) with a small torque wrench.
NOTICE
Use a second wrench to prevent movement on the fitting body.
Do not
apply excessive torque as this might permanently damage the connection.
The conduit screw must be properly tightened to prevent gas leaking from the
connection point.
5
Repeat steps 1 to 4 for the second gas line.
6
Route the three remaining cables (sensor head AC, sensor head DC, Modbus) immediately to the left
of the bulkhead fitting.
7
Put back the cable cover.
