1.管线清洁

2.控制盘指示检查,上部箭头指向“service”,下部按钮是否在“tank1”。

Checkontheindicationpanelofthecontrolifthetopindicationarrowisinposition”service”

如果没有,连上墙上的电源。

顺时针轻轻旋转旋钮到“manualregeneration”,直到阀门马达开启。

连续重复直到箭头指向前面描述的位置(Descriptionofvalvehead)

再次轻轻旋转旋钮到“manualregeneration”,直到指示箭头在“backwash”和“tank2”的位置。

关掉控制电源。

轻轻开启阀门进水。

滤罐1充满水,连续进行直至流出的水比较清洁并且没有气泡,关闭阀门。

断开控制单元电源。

轻轻打开连接阀门进水。

这时盐罐补水水。

自动完成。

测量水量。

根据滤器的类型,盐罐冲水量必须和“saltsolution/regeneration”计算的一样。

如果总量不同,根据“Adjustmentofprogramwork”进行调节。

再用软管多加10cm。
