3. Connect the discharge to the sewerage system.
4. If the incline of the discharge pipe is insufficient, install a lifting station in order to guarantee the
discharge.
4.3 Mains water pipe connection
Proceed as follows:
1. Connect the mains water supply pipe to the 3/4" threaded outlet on the righthand side of the tank
(see fig. 01 point 8).
2. Check that the float valve moves freely and that it is correctly positioned within the mains water
tank (see fig .02A,). The float should be able to move freely.
WARNING

Make sure that the level regulation float does not turn when tightening the pipe.

The float valve that regulates the discharge of mains water is designed to operate at a
maximum pressure of 4 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 (see Table 1). 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).
The point of suction must always guarantee the suction of clean water, use a suction kit and install it
as illustrated in figure 03.
