2 INSTALLATION

The system is designed to be able to work in environments where the temperature remains between 0°C
and 50°C (on condition that the electric power supply is ensured: see par.6.6.14 "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.
If the system is used for the domestic water supply, respect the local regulations of the authorities
responsible for the management 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 flooding.
 The electrical system is provvided with a differential switch sized according to the
characteristics indicated in Table 2
 The equipment requires an earth connection.
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).

2.1 Hydraulic connection

The Inverter works at constant pressure. This regulation is most appreciated if the hydraulic
system downstream from the system is suitably sized.
Systems made with excessively narrow pipes can cause load losses which the appliance is unable to
compensate for; the result is that the pressure is constant on the device but not on the utility.
RISK OF FROST: pay attention to the installation site of Inverter! Take the following precautions:
If the Inverter is operative it is absolutely necessary to protect it adequately against frost and to leave it
constantly powered. If it is disconnected from the power supply, the anti-frost function is no longer active!
If the Inverter is not operative it is necessary to turn off the power supply, disconnect the appliance
from the pipe and completely empty out all water left inside.
It is not sufficient just to remove pressure from the pipe, because some water is always left inside!
There is already a non-return valve inside the inverter, so it is not necessary to fit an external one.
The hydraulic connection between the Inverter and the electric pump must not have any derivations.
The dimensions of the pipe must be suitable for the electric pump installed.
