GENERAL DESCRIPTION OF THE RAIN SYSTEM
A control unit controls the management and distribution system of the rainwater. The main scope of this control unit is to give priority to
rainwater consumption rather than mains water. Generally, the system is delimited to an irrigation system, washing machine, toilet flush tank
and floor washing (N.B. The water supplied by the system is never drinkable).
The control unit controls the inflow of drinking water even if you want to use mains water instead of rainwater. The two independent water reserves
(rainwater and mains water) ensure the regular working of the system. This switch can take place via a manual command, or automatically
(using a level indicator for the accumulated rainwater) if the tank does not contain a sufficient rainwater reserve.
The control unit is equipped with “open drainage” in compliance with the standard EN 1717, and with a safety device that prevents any possible
contaminants in the tank to come in contact with the water mains.
Basic characteristics of the control units (Models “S” and “F”):
•
The control units work with an automatic electronic device and are equipped with an external, multi-stage, self-priming, centrifugal
pump.
•
The control units are also equipped with an automatic system to switch to the intake of drinking water if the rainwater reserve tank is
empty; if needed, this operation can take place manually.
Additional characteristics of the Model “F” control unit:
The “F” model control unit, in addition to the characteristics of the “S” model, is equipped with a microprocessor with these additional
features:
•
signals any anomalies in the system via acoustic and optical indicator;
•
indicates the level (expressed as a percentage) of the water collected inside the underground tank;
•
periodically replaces the water collection inside the small tank of the control unit to avoid standing water in the drinking water supply
pipes;
•
allows installation of an additional submersible pump.
Characteristics of the “PX” module:
System equipped with a stainless steel submersible pump and a safety device.
