MAINTENANCE
Cleaning the capacitive sensor
It is necessary to remove any adhesive residue that may remain on the sensor
regularly (at least once every three months) to prevent any incorrect level rea-
dings. It is also advisable to clean it when cleaning the tank or when changing
the type of adhesive.
1. With the adhesive block removed from the unit and the adhesive level
below the sensor, remove the screws from the clamp bushing.
2. Thread the screws through the bushing’s threaded extraction holes so
that it can be removed from its housing in the tank.
3. Clean the adhesive residue off the sensor, the bracket’s housing and the
sealing gasket. If the gasket is damaged, replace it with a new one.
Attention: Do not remove the sensor from the bracket.
4. Reinstall the bracket in its housing in the tank. Ensure that the fastening
screws are properly tightened
