2. Turn on the power supply after 1 minute of water supply, the "system power" indicator, "pump work" indicator, "water inlet" indicator is on at the same time, the machine will start to run. The machine will start to run.
3, the machine will automatically flush the RO membrane and UF membrane 18 seconds each time the machine is turned on, at the same time, "system flushing" indicator light; 18 seconds later, "system flushing" indicator light off, the end of the system flushing, the machine enters the normal state of water production.
4, pressure control system
(1) the first level of pressure control system for when the source water has a certain pressure, the first level of low-pressure switch closure, in each level of pressure tank is not full (the first level of high-pressure switch is not disconnected), the first level of the water inlet solenoid valve to open the first level of the pure water pump to start the first level of the water tank has a gauge to monitor the pressure of the water tank.
(2) when the first stage of the water tank has a certain pressure, the second stage low pressure switch closed, in the second stage of the water tank is not full (the second high-pressure switch is not disconnected), the second stage of the pure water pump to start, at the same time the second stage of the water inlet valve is open, when the second stage of the water tank is full of water (the second stage of the high-pressure switch is disconnected), the second stage of the pure water pump stops running, at the same time the second stage of the water inlet valve is closed. When the first stage tank is full of water (the first stage high pressure switch is disconnected), the first stage pure water pump stops running, while the first stage water inlet solenoid valve is closed.
5, pure water access:
Lightly press the "RO water" button, RO water nozzle can be access to RO purified water, and then press to close.
Lightly press the "UP water" button, UP water nozzle can take UP ultrapure water, at the same time the UP water quality online monitor on the upper part of the control panel of the machine shows the UP water quality in the pipeline at this time, and then you can press to turn off; with the "ultraviolet elimination" function of the model, press the "UV elimination" function, press the "UV elimination" function, press the "UP" function. models with "UV digestion" function, press the "UP water" button, the UV instrument at the same time to start the "UV digestion" indicator light, 185nm/254nm dual-wavelength UV lamp can kill more than 99.8% of the bacteria in the water and oxidize and decompose the residual organic matter in the water, then The terminal filter removes the residual bacteria and fine particles in the pure water, and the TOC content of UP ultrapure water can be as low as 5~10PPb.
