Determine whether the flow switch and the system
connected with it are in good operation according to the
measured value by flow meter, namely, when the measured
value on flow meter is less than 60% of rated water flow of
the unit, the target flow controller should be cut off and
observed for 3 working periods, and it should be covered
with flow switch shell timely.

4.10 Installation of single-module water system
pipeline
Be sure to determine the model of target slice according to
the rated flow of the unit, the diameter of the outlet pipe
and the adjustment range of the target slice of the flow
switch. Besides, the target slice should not contact with
other restrictors in the pipeline or on the inner wall of the
pipeline, or the flow switch cannot be reset normally.
