WARNING
The float valve that regulates the discharge of mains water is designed to operate at a maximum
pressure of 6 Bar and a flow rate of over 10 l/min. If the mains pressure exceeds this value, fit a
pressure reducer upstream from the float valve ad a mesh filter to protect it against any impurities that
endanger its operation. Excessive pressure in the mains pipe could cause the float valve inside the
system to leak or break.
Ideally an on-off valve should be fitted before the float valve so that the mains water can be turned off
in the event of breakage or malfunction, and so that maintenance can be performed in total safety.
4.4 Collection water suction pipe connection.
The suction pipe must have an internal diameter of at least DN25, and must always have an incline
towards the collection tank. Before connecting it to the system, make sure that there are no air locks
and that it is clean, if necessary clean it with clean water.
Install the system as close as possible to the rain water collection tank. Use the table below in order to
ensure that the distance is not excessive, a suction height of 6 meters should never be exceeded in
order for the pump to perform at its best (total between the effective suction distance and penalization
of the suction based on the length of the suction pipe).
If the suction height is over 6 m use another pump connected in series with that of the system in order
to reduce the difference in height.
The point of suction must always guarantee the suction of clean water, use a suction kit and install it
as illustrated in figure 03.
Always install a filter to ensure that impurities are prevented from blocking valves and other internal
parts of the pump.
