as to be able to fill it quickly too during the loading operation. In this case the
quantity of water necessary for the loading operation will depend on the length
of the suction pipe (0,7 litres + ...).
Installation "below head": if there are no check valves between the water de-
posit and the system (or if they are open), it loads automatically as soon as it is
allowed to let out the trapped air. So slackening the filling cap (Face F - Fig.1)
enough to vent the air allows the system to load completely. You must survey
the operation and close the loading door as soon as the water comes out (how-
ever it is recommended to fit a check valve in the section of the suction pipe
and to use it to control the loading operation with the cap loose). Alternatively,
in the case where the suction pipe is intercepted by a closed valve, the loading
operation may be carried out in a similar way to the one described for installa-
tion over head.

The suction depth must not exceed 8 m.

To improve immunity to the possible noise radiated towards other appli-
ances it is recommended to use a separate electrical duct to supply the
product.
Attention: always respect the safety regulations!
Electrical installation must be carried out by an expert, autho-
rised electrician, who takes on all responsibility.
The system must be correctly and safely earthed as required by
the regulations in force.
The line voltage may change when the electropump is started.
The line voltage may undergo variations depending on other de-
vices connected to it and on the quality of the line.
It is recommended to carry out installation as indicated in the
manual, in compliance with the laws, directives and standards in
force in the place of use and depending on the application. The
product contains an inverter inside which there are continuous
voltages and currents with high-frequency components (see ta-
ble 0).
