7.2.1. Lime-scale removal
Sooner or later, depending on the water quality, lime-
scale deposits will build up on the system. These
must be removed carefully.
)
Only use products for lime-scale removal that
are based on citric acid, amidosulphuric acid
or phosphoric acid.
)
Mix these with water in the proportions speci-
fied by the manufacturer.
)
Use these products to remove the lime-scale
deposits carefully from the system.
)
Rinse the system down with plenty clear wa-
ter.
Use of other products, such as cleaners that con-
tain hydrochloric acid, sulphuric acid, formic
acid, hydrofluoric acid or oxalic acid or incorrect
mixing proportions, can cause corrosion damage
and damage to tiles and the surface of the sys-
tem.
For damages caused by using one of the clean-
ers stated above no warranty claims will be ac-
cepted.
When removing lime-scale, avoid bringing the
products into contact with plastic components,
belts, sensors and cables. The acidic mixture can
cause damage to these elements.
)
After removing lime-scale, check the pH-value
in the water recycling system. The pH-value
must be between 7,0 and 8,0.
)
Wash at least 30 vehicles with fresh water if
the pH-value is below 7.
