It results that, with SP = 3.0 bar, the system is able to ensure a constant pressure at the users that require flow rates respectively between 0 and
85 litres/minute. For higher flow rates the system works according to the characteristic curve of the electropump at maximum rotation speed. For
flow rates lower than the limits described above, as well as ensuring constant pressure, the system reduces the absorbed power and therefore
the energy consumption.
The above performances are to be considered measured at ambient temperature and water at about 20°C, during the first 10 minutes
of motor operation, with water level at suction at a depth of no more than 1 metre.
As the suction depth increases, the performance of the electropump decreases.

4. INSTALLATION
– The system is designed for indoor use. In the case of outdoor installations and/or those directly exposed to atmospheric agents, it
is recommended to adopt protection appropriate to the context of installation, in order to guarantee correct operation of the system
under all conditions.
– The system is designed to be able to work in environments where the temperature remains between 0°C and 50°C (on condi-tion
that the electric power supply is ensured: see par.9.6 "AF: anti-freeze function").
– The system is suitable for treating drinking water.
– The system cannot be used to pump salt water, sewage, inflammable, corrosive or explosive liquids (e.g. petroleum, petrol,
thinners), greases, oils or food products.
– The system can take in water the level of which must not be at a depth greater than 8m (the height between the water level and the
pump suction mouth).
– Do not connect any pipe to the 1¼'' mouth that houses the non-return valve, see fig. 26.
– If the system is used for the domestic water supply, respect the local regulations of the authorities responsible for the management
of water resources.
If you are not sure of the absence of foreign bodies in the water to be pumped, install a filter on the system intake that is suitable for catching
impurities.
The installation of a filter on intake causes a decrease of the system's hydraulic performance proportional to the loss of load caused
by the filter itself (generally the greater the filtering power, the greater the fall in performance).
Choose the type of configuration you intend to use (vertical or horizontal) considering the connections to the system, the position of the user
interface panel, and the spaces available according to the indications below. Other types of installation configuration are possible using DAB
accessory interfaces: see dedicated paragraph (par. 11.2, 11.3).
