Connecting the sample lines

Note.

Sample inlet tubing is customer-supplied.

Keep sample drains as short as possible and vertical to
enable the sample to drain freely.

Where particulate matter is present (for example,
magnetite in boiler samples) it is recommended that a 60
micron sample filter is fitted to the sample inlet line.
To make external sample inlet connections:
1. Fit a shut-off valve (not supplied) at each sample inlet.
Referring to Fig. 3:

3. Ensure the drain tubing
is routed to a suitable drain.
4. Ensure the 2 drain tubes
are kept as straight as possible and routed through the funnel

at the base of the wet-section. Drain tubes are
factory-fitted but may have moved in transit.

Connecting the standard solution
2 (high) and reagent tubing
Connections to the standard solution 2 (high) and reagent
containers (at the QD couplings) must be made on site. All other
internal wet-section tubing connections are factory-made.
Note. If reagent and standard solutions have not already been
prepared, proceed to Solution preparation (overleaf).
Referring to Fig. 44:
1. Fill the standard solution 2 (high) and reagent containers with
the correct solutions – refer to Solution preparation.
2. Connect the standard solution 2 (high) tubing QD coupling
