Water Hardness Analyzer
AW101 Testomat
2.2 Sample Supply
The temperature of the sample water must be between 10 and 40 °C (50 and 105 °F). Higher water temperatures can lead to
damage to all parts coming into contact with water (for example, the filter housing or measuring chamber). Lower water temperatures
can cause misting on the sight-glass windows.
In the event of higher temperatures, install a cooler in the sample line of the AW101.
Position the sample line (fitted with a hand-operated shut-off valve) as close as possible to the outlet from the water softening plant.
Keep the sample line to the AW101 as short as possible and not longer than a maximum of 5 m (16.04 ft.). It is important that the
sample line connection is taken vertically from the top of the main soft water line in order to prevent dirt particles from entering into the
measuring chamber.

2.3 Electrical Connection
Check the supply voltage on the rating plate.
2.3.1 Basic Requirements
Keep the external cables (for example, water meter and interface) clear of the power cables and as short as possible.
2.4 Plug Connector
The unit is equipped as a standard with a plug connector for opaque plastic hoses (external diameter 6 [0.24 in.] mm/internal
diameter 4 mm [0.16 in.]).
2.5 Sample to Drain
The feed water flows through the measuring chamber then, via the outlet pipe, to the drain (hose connection internal diameter 14 mm
[0.44 in.]). Ensure, by using a funnel for example, that the water can run freely to drain and cannot backup into the measuring
chamber. Use a hose impervious to light for the drain pipe (to discourage algae formation).
