6.4. Installation and use of by-pass
The by-pass valve has the shunt function. If the position of the keys is parallel to the inlet/
outlet, the valve is in service state; whereas, when in opposite position (by-pass), the
valve is in by-pass state. A quick joint structure is adopted for connecting the valve to the
bypass, with reliable sealing characteristics.
6.5. Mixing Function (Outlet water hardness correction)
If the user considers that the hardness of the outlet water is too low, he can adjust it by
using the water mixing function using the Bypass Valves.
