5.10.7 Cotton like Fill Scale

Cotton like Fill Scale is normal and occurs on the leading edge of the fill, it occurs because of

the high evaporation rate at this leading edge and the diminished flow that is normally found at

this area of the fill as well. This type of scale is normally very soft and can be removed with a

manual spray nozzle cleaning as needed.
