2- INSTALLATION
The system is designed for indoor use: do not install the system
outdoors and/or directly exposed to atmospheric agents.
The system is designed to be able to work in environments
where the temperature remains between 1°C and 50°C (on con-
dition that the electric power supply is ensured: see par. 5.6.8
“anti-freeze function”).
The system is suitable for treating drinking water.
The system cannot be used to pump salt water, sewage, inam-
mable, corrosive or explosive liquids (e.g. petroleum, petrol, thin-
ners), greases, oils or food productsi.
The system can suck up water with a level that does not exceed
the depth of 8 m (he height between the water level and the
pump suction mouth).
If the system is used for the domestic water supply, respect the
local regulations of the authorities responsible for the manage-
ment of water resources.
When choosing the installation site, check that:
• The voltage and frequency on the pump’s technical data plate
correspond to the values of the power supply system.
• The electrical connection is made in a dry place, far from any
possible ooding.
• The earth system must comply with the regulations.
If you are not sure of the absence of foreign bodies in the water to be
pumped, install a lter on the system intake that is suitable for catching
impurities.
The installation of a lter on intake causes a decrease of the
system’s hydraulic performance proportional to the loss of load
caused by the lter itself (generally the greater the ltering pow-
er, the greater the fall in performance).
Choose the type of conguration you intend to use (vertical or horizontal)
considering the connections to the system, the position of the user inter-
face panel, and the spaces available according to the indications below.
Wall installation is possible, see par. 8.2.
2.1 - Vertical Conguration
Screw the 4 rubber feet supplied loose in the package into the brass seats
in face C. Put the system in place, taking into account the dimensions in
