Installation conditions
•
The permitted ambient temperature (see chapter "Technical data") must not be
exceeded both on installation and operation.
•
A solid foundation must be available. For dimensions see the foundation plan
(

Chap. 3.2.3)
•
Install vertical and level
•
Outside installation: Avoid direct sunlight on the front of the unit. If required, fit a sun
protection system (all-weather roof)
•
If the water in and outflow pipework is installed in the open air, these should be
protected from frost
•
Because the analysis component has to be continuously rinsed with water, it must be
guaranteed that there is always enough water available at the sampling point so that
dry running of the system is avoided (e.g. small weir etc)
The feed hose should therefore be fixed as required
"
Caution!
Dry running and sand grains/particles can shorten the life span of the eccentric pump.
•
The outflow hoses must be installed falling away from the unit and with free outlet
•
When using the manual or automatic cleaning system, an isolation valve and pressure
reducer must be installed on site
3.2.1
Material resistance of the analysis pipework
The analysis system consists of a PVC pipework system and due to its material
composition is suitable for drinking water and beverages.
General chamical resistance
Resistant: Acids and bases
Non-resistant: Aromatic solvents
Application limits for pressure and temperature
(25-year values with calculated safety factor)
Type used: PVC-PN10
