Anti-incrustation - „ALTO No Scale“
Light indicator: insufficient „No Scale“
Dark indicator: sufficient „No Scale“
Only use „ALTO No Scale“.
To avoid incrustation of the piping of the boiler and thus ensure optimum operation, an anti-incrustant -
„ALTO No Scale“ should be added, which is available from your ALTO distributor. Fill the anti-incrustant
through the socket (1) and it will automatically be added to the water in a balanced dosage. Any lack of
„ALTO No Scale“ will appear from a change of colour from dark to light on the indicator (2).
