(4) Remove the packing at the top of the water flow sensor, then
adjust the flow rate setting screw to find the position where the
flow rate sensor is placed in the conduction state (on).
(5) From the found position, turn the flow rate setting screw of the
water flow sensor counterclockwise until the water flow sensor is
in the state immediately before it becomes off.
(6) Increase the cooling water flow rate gradually to the alarm-off
setting flow rate, then check that the water flow sensor is on.
