• Disengage the 4 screws at the corners of the panel using the accessory tool.
• Do not remove the screws completely, just disengage them from the thread on the
product body.
• Be careful not to drop the screws into the system.
• Move the panel away, taking care not to pull on the signal transmission cable.
• Reposition the panel in its seat at the preferred angle taking care not to pinch the
cable.
• Tighten the 4 screws with the wrench.
2.2.3 Loading Operation
Installation above head and below head
With reference to its position with respect to the water to be pumped, the installation of the system
may be defined "above head" or "below head". In particular the installation is defined "above head"
when the pump is placed at a level higher than the water to be pumped (e.g. pump on the surface
and water in a well); vice versa it is "below head" when the pump is placed at a level lower than
the water to be pumped (e.g. overhead cistern and pump below).
Installation "above head": with a screwdriver, remove the filling cap which, for the horizontal
configuration, is the one on Face F (Fig.1). Fill the system with clean water through the loading
door, taking care to let the air out: to ensure optimum filling it is convenient to open also the
loading door on Face A (Fig.1), used for filling in the vertical configuration, so as to let all the
air out, which otherwise could remain trapped in the system; take care to close the openings
correctly once the operation is completed. The quantity of water with which to fill the system
must be at least 0,7 litri almeno. litres. It is recommended to fit a non-return valve at the end of
the suction pipe (foot valve) so 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 deposit 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 com-
pletely. You must survey the operation and close the loading door as soon as the water comes out
(however 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 installation over head.

The suction depth must not exceed 8 m.
3.1 - Electrical Connections
To improve immunity to the possible noise radiated towards other appliances it is recom-
mended to use a separate electrical duct to supply the product.

The line voltage may change when the electropump is started. The line voltage
may undergo variations depending on other devices connected to it and on the
quality of the line.
It is recommended to carry out installation as indicated in the manual, in compli-
ance 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 table 0).
