Installation above head and below head
Installation “above head” (par. 2.1.1): access the technical compart-

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

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-

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.
