Replacing water sensors
The sensors for detecting temperature, conductivity, and decreases in pressure are installed
in the water piping.
Device damage due to water
If water enters the cabinet while a water sensor is being replaced, this can result in material
Before replacing a water sensor, empty the entire water circuit and blow out the piping.
Removing a sensor
To remove a sensor, proceed as follows:
1. Loosen the screw in the sensor cover
2. Pull out the connector.
3. For the temperature sensor, loosen the two screws in the sensor cover
4. Remove the cables connected to the sensor.
5. Unscrew the sensor from the screw connection in the water pipe.
