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

Installation "above head": with the aid of the accessory tool (Fig.3_point 5) or

with a screwdriver, remove the filling cap which, for the horizontal configura-

tion, 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. The quantity of water with which to

fill the system must be at least 1.5 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 (1.5

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
