Cleaning the sensors
The three sensors should be cleaned every 3 months, if the water is very dirty it is advised to clean the sensors more
frequently.
To maintain sensors functionality, it is important to clean the sensors regularly.
The pH sensor must be removed from the measuring chamber in order to clean it properly without damaging it. Unscrew
the four bolts holding the sensor in place. See Illustration 36 on which bolts to remove.

surface e.g. a clean rag.
