Changing the connector arrangement may increase the risk of leakage or incorrect installation.
4. Confirm the water-flow direction
Install the ICS518 according to the illustrated water-flow direction.
Correct direction is important for measurement accuracy.
5. Tighten all connections
Make sure all connectors are securely installed before turning on the water.
Check for leakage during the first test.

Briefly press the front button until FLOW MODE appears.
Turn on the water and confirm that a real-time flow value is displayed.
