Open ball valve (BV1) completely. (BV3) closed. Adjust ball valve (BV2) and needle valve (NV1)

and make the flow rate into free available chlorine detector between 0.1 and 2.5 L/min.
(BV3) is used for manual zero adjustment and washing. To stabilize the zero filter with water,

refer to Section 6.1.7 of IM 12F5A1-01E or Section 3.8 of IM 12F05B10-02EN.
