1. The water yield of pure water equipment is over 1000L/H at 25 C. The water temperature of rural drinking water equipment rises or falls by 1 C. The water yield will increase or decrease by about 3%, which is determined by the characteristics of RO film.

2. Water entering RO membrane should strictly control the content of residual chlorine school drinking water equipment below 0.1 ppm. The method is to connect water at the sampling port of the adsorption filter and use residual chlorine determinant of ultra-pure water treatment equipment to detect residual chlorine. If exceeding the standard, activated carbon filter material should be replaced.

3. If the water intake is insufficient or the pressure is too low, the water shortage and under-pressure system of pure water equipment will cause the equipment to stop automatically.

4. When pure water equipment is used for the first time, because RO film contains preservatives, the outlet water conductivity will be on the high side. After washing for 1-2 hours and making water normally for a period of time, the outlet water conductivity will be significantly reduced.
