bubbles in the suction pipe). The suction pipe must draw at its
entrance at a depth of at least 30cm below the water level and
must be watertight along its whole length, as far as the entrance
to the electropump.
The suction and delivery pipes must be fitted so that they do not
exert any mechanical pressure on the pump.
2.1.2 Loading Operation
Installation above head and below head
Installation "above head" (par. 2.1.1): access the technical compart-
ment and, with the aid of the accessory tool (Fig.3_point 5) or with a
screwdriver, remove the filling cap (Fig.3_point 6). Fill the system with
clean water through the loading door, taking care to let the air out. If the
non-return valve on the suction pipe (recommended in paragraph 2.1.1)
has been placed close to the system entry door, the quantity of water
with which to fill the system should be 2.2 litres. It is recommended to fit
the 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 (2.2 litres + ...).
Installation "below head" (par. 2.1.1): 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 slack-
ening the filling cap (Fig.3_point 6) enough to vent the trapped air allows
the system to load completely. You must survey the operation and close
the loading door as soon as the water comes out (however it is recom-
mended to fit a check valve in the section of the suction pipe and to use
it to control the loading operation with the cap open). 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.

2.2 - Horizontal Configuration
Remove the 4 support feet from the bottom tray of the packaging and
screw them fully into their brass seats on face E. Put the system in place,
taking into account the dimensions in Fig.10.
• The distance of at least 270mm between Face B of the system
and an obstruction is recommended so as to be able to carry out
maintenance on the non-return valve without disconnecting the
system.
• The distance of at least 200mm between Face A of the system
and an obstruction is recommended so as to be able to remove
the door and gain access to the technical compartment.
• The distance of at least 10mm between Face D of the system
and an obstruction is obligatory to let out the power supply cable.
If the surface is not flat, unscrew the foot that is not touching and adjust
its height until it contacts the surface so as to ensure the stability of the
system. The system must in fact be placed in a safe and stable position,
ensuring that its axis is vertical: it must not be in an inclined position.
