4.2 Sampling Requirements

The sampling point must be as near as possible to the analyzer
and must provide a thoroughly mixed, representative sample.
The sample must conform to the following conditions:

Sample must contain less than 10 ppm suspended solids
with a particle size no greater than 60 µm.
(If particle sizes exceed 60 µm, use a 60 µm filter.)

Sample temperature must be within the range 5 to 55 °C
(41 to 131 °F).

Sample flow rates must be within the range 20 to 500
ml/min.

Sample must be at atmospheric pressure.

4.3 Location
For general location requirements refer to Fig. 4.1. Install indoors
in a clean, dry, well ventilated and vibration-free location giving
easy access and where short sample lines can be used. Avoid
rooms containing corrosive gases or vapors – for example,
chlorination equipment or chlorine gas cylinders.
Select a location away from strong electrical and magnetic
fields. If this is not possible, particularly in applications where
mobile communications equipment is expected to be used,
screened cables within flexible, earthed metal conduit must be
used.
It is also advisable to ensure drains are adjacent and near
ground level, so that the analyzer waste outlet can be as short
as possible, together with maximum fall.
Mount reagent solutions less than 1 m (3.28 ft) from the bottom
of the analyzer housing – see Fig. 4.2, page 15.
Ensure that the power supply and power isolation switch are
adjacent to the analyzer.
