Aztec 600 ISE ammonia and fluoride
Single-stream ion-selective analyzers
3 Installation
3.1 Optional Accessories
Optional accessories comprise:
 Reagent tray
 Calibration solution level sensor(s)
 Profibus capability (including separate manual – part no. IM/AZT6PBS)
3.2 Sampling Requirements
Selection of a good, representative sampling point is critical to obtain optimum performance from the analyzer.
To reduce sample dead time, locate the analyzer as close to the sampling point as possible.
Use small diameter tubing for the sampling line to minimize the lag time but large enough not to block.
The sample must also conform to the following conditions:
 Sample flow rate must be greater than 200 ml/min (7floz[US]/min) and less than 500 ml/min (17 fl oz [US]/min).
 Sample temperature must be within the range 1 to 40 °C (32 to 104 °F).
Samples must not contain particles exceeding 100 microns in size. Above these levels, an external filter must be fitted to the sample lines.
 Sample must be at atmospheric pressure. It must be as close to the analyzer as possible and the sampling point must provide a thoroughly mixed representative sample.

3.3 Location
For general location requirements refer to Fig. 3.1. Install 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.
It is also advisable to have adjacent drains near ground level, so that the waste outlet from the analyzer can be as short as possible, together with maximum fall.
If the optional reagent tray is used, mount it directly below the bottom tray of the analyzer housing – see Section 3.4.1, page 11.
The power supply and power isolation switch must be adjacent to the analyzer.
