Grundfos SCALA1 System - Product Introduction; Product Description; Suitable Pumped Liquids; Mechanical Installation

2. Product introduction
2.1 Product description
The SCALA1 System is used to manage and
distribute rain. The system is suitable for irrigation,
water flushing of toilets and floor cleaning systems.
The system prioritises the use of rainwater over tap
water. In case of insufficient rainwater in the tank, the
control unit switches to tap water to ensure the
necessary water flow at the tapping points. The
system automatically switches between the rainwater
tank and the tap water tank by means of a three-way
valve installed on the pump inlet port. The water
supplied by the system is not potable.
