This type of connection requires preparation of the water supply system. Direct connection to the water supply is not recommended; typically, 3- or 5-cell filters are used for water purification.
Attention! Installation of water supply regulation devices is prohibited!
A 6mm diameter PVC hose is used to connect to the machine's nipple. Ensure that the water supply pressure is at least 0.15 - 0.8 MPa (1.5 - 8 bar).
Connection procedure:



The water supply connection setup is complete.
In some cases, if the water pressure in the water supply system is high, the solenoid valve may not open (the machine displays error 1, and no water is pumped when reset). The solution is to reduce the pressure using the supply regulator. If this doesn't work, add voltage (turn clockwise) to the UPS board transistor.
