Installation
4.4.4 Sample tubes installation
• Sample inlet connections - 6 mm (or ¼'') in polyethylene or PTFE or FEP. If particulate
matter is present in the sample, pre-filtration is necessary. A filter should be inserted in the
sample line. One is available as an option. Use new pipes for all connections during
installation.
• Flow rate - 6 to 9 L/hour
•Pressure - 0.2 to 6 bars (8 to 100 psig)
• Sample acidity - Sample acidity should not be more than 300 ppm CaCO
3
• Temperature - Temperature must be between 5 to 45 °C
At this stage of the installation, make sure that the flow valve is closed.
Connect the pipes by inserting them into the quick release connections found under the
sampling block. Connect one inlet and one outlet per channel.
Be sure that the sample line is correctly flushed before any connection to avoid particle injection
into the 9240 hydraulic system.
1. Connect the drain outlet.
2. Connect the sample inlet/outlets. Up to four are available, though the illustration below
shows only one channel connected with the other three inlet/outlet connections still
available
A - Drain outlet - 12/17 mm B - Sample outlet tube - 4/6 mm
C - Sample inlet tube - 4/6 mm
