Prepare a location-type water sensor or water detection cable of the same model.
The location-type water sensor consists of a water leakage locator, tieline, and water
leakage location cable. The water detection cable is laid out on the floor. The liquid level
sensor is deployed around the collector. The water detection cable and the liquid level
sensor are connected using the lead wire.
Recommended tool and material: crimping tool
Pull out the water detection cable from the lead wire port on the water leakage locator.
Remove the water leakage locator from the DIN guide rail.
Install the new water leakage locator on the DIN guide rail with the latch facing
upwards.
Touch grounded devices or pipes to eliminate ESD before taking the water sensor module.
