Return Line Installation
The return hose fitting is a 12 mm (
1
/
2
”) hose barb on the bottom of the regulator output port and
should always be connected even when pressure is below 1 bar.
INSTALLING THE INPUT FILTER
In order to ensure maximum accuracy of measurements, it is recommended to have always clear
sample, with suspended particles smaller than 0.5 µm. This can be achieved by installing two
filters before the sample input.
The type of filters depends on the quality of the water: the first filter should have 50-100 µm pore
size, whereas in any case the second filter, the one closer to the analyzer, has to be 0.5 µm.
For correct instaling procedure and maintenance, see the instructions of filters.
INSTALLING THE pH AND ORP PROBES
To mount the pH and ORP probes, first turn off the analyzer.
Unscrew the closing caps from the electrode holder and remove the protective cap from electrodes and
electrodes connectors.
