Water Block (WB) SAFETY VALVE
Indispensable device for washing machines, dishwashers and demineralizers as, under the conditions defined in the technical features
herewith described, it prevents a flow of water greater than the one for which it has been set by the adjustment pointer.
This avoids continuous leaking. The Water Block also has a particular non-return valve (antipollution).
The device should be installed vertically (
see fig.2
) and following the instructions carefully.

USER INSTRUCTIONS
Water Block should be installed between the tap and the supply hose of the demineralizer (
fig. 2
).
Using the enclosed plastic key, turn pointer ‘P’ (
fig. 1
) counter-clockwise to the required setting
(example, position 1,5).
For use on other fixtures, set the pointer to a position suitable for that particular application, considering that each number on
the scale corresponds to a controlled volume of approx. 4-6 litres.
In case of installation on drinking water lines, it is recommended to let flow at least 10 litres of water inside the device before the
connection, so as to remove all impurities banked during the storage.
