WATER DISINFECTION SYSTEM
Water disinfection system is obtained by adding hydrogen peroxide (2,35%) to the water
When the mixing cup is empty, the sensor sends the signal to the Stand Controller, the V27 air valve
opens to pressurize the tank and close the non-return valve. The V31 pump is activated for 2 seconds (1
ml per second) at the end of filling. The “Stand controller” opens the water solenoid valve (V30) which
automatically stops the sensor probe (upper level). At the end of the filling process, the controller stand
sends a signal to the V27 solenoid valve, which closes and releases the pressure inside the tank. This
process allows the valve to be released and the tank to be filled. The cycle is repeated until the tank is
full, an operation managed by the "controller stand AO-891".
