Installation
Establish supply line to the sample water and to the canal
The connections for inlet and outlet are designed for flexible plastic hose with 1/4-inch
outer diameter.
A manual shut-off valve must be provided between the preparation unit and the analyser. A
suitable valve can be found in the product catalogue or in the spare parts list. When connecting
to a drinking water pipe, the installation must take EN 1717 into account. The drain must lead
into an open channel via a short connection. The drainpipe must remain depressurised.
Make sure that the inlet and outlet are not interchanged. The inlet is located on the left
side of the inlet filter.
Pressure
The inlet pressure of the water sample must be between 0.5 and 5.0 bar.
The recommended inlet pressure of the water sample should be between
1 and 2 bar.
The hose length of the water drain must not be longer than 2 m and must
lead away vertically downwards. The system must be able to relax freely
against the atmospheric pressure (no counterpressure). The water drain is
pressureless into an open funnel or drain.
