The design of the water softener is very advanced, all microcomputer operations, generally no human operation is required. The following points should be noted during use: 1. Soft water machines should be kept away from heat sources or necessary thermal insulation measures should be taken, and they must not be connected to hot water pipes or pipes that may cause hot water backflow. 2. When the raw water does not meet the municipal tap water standard, such as high sand content, excessive residual chlorine, etc., pre-treatment equipment should be installed before the soft water machine. 3. There should be enough space between the soft water machine's drainage pipe and the drain floor trap to prevent siphonage. 4. After installation, the valve head should be adjusted to the backwash position first, then the inlet valve should be opened, with the aim of discharging the resin protective liquid into the sewer. Then start the immediate regeneration program, and pay attention to observe whether each program runs normally during regeneration. 5. The soft water machine should use special salt, insoluble impurities should be less than 1%, and the use of various additive salts is prohibited. 6. During the operation of the soft water machine, users should check the amount of salt in the salt tank. Each salt addition should reach two-thirds of the height of the salt tank, and when the salt level is lower than one-third, it should be added in time. 7. A salt bridge may form in the salt tank, which is a space formed under the salt layer. During the regeneration process, the salt cannot dissolve in the water to make brine, so the失效resin will not be regenerated, and the soft water machine will not produce qualified soft water. Users should frequently check whether there is a salt bridge at the bottom of the salt tank, and if there is a salt bridge, please crush it. &；nbsp； Related thematic articles: What kind of inkjet printer should be used for what kind of product New occupation: Indoor environmental management engineer Basic knowledge
