4.2.1
"ECO-BALL" ball valve
The "Eco-ball" valve consists of a sphere
contained inside the tube that connects the tub to
the filter body. Its purpose is to keep the washing
water (contained in the tub) separate from the
water in the drain circuit.
Advantages with respect to a conventional circuit:
Energy savings: the water inside the drain circuit is not heated.
The detergent does not deposit on the filter body, thus improving the quality of the wash (reduction in
mechanical detergent losses).
Better rinsing efficiency.
