Cleaning and care instructions
6.1 Stainless steel outer wall terminals
NOTE
The thin and transparent passive coating on the surface protects the stainless steel against corro-
sion. However, dust and other soiling from the atmosphere can still be deposited on the surface,
causing flash rusting.
►
Do not remove the protective film from the outer wall terminals until the installation is com-
plete.
►
Clean the outer wall terminals after installation using a soft, lint-free cloth and stainless steel
cleaner.
►
Remove any flash rust that is already present using a soft, lint-free cloth and stainless steel
cleaner.
►
Immediately remove particles of iron, metal filings, plaster and swarf from the surface of the
outer wall terminals.
►
Remove lime and cement spatter as quickly as possible before it hardens from the surface of
the outer wall terminals.
►
Do not use abrasive cleaning utensils (pan scourers, steel wool, etc.) and do not use clean-
ing agents containing chlorine or hydrochloric acid.
NOTE
Corrosion caused by flash rust is not covered by the warranty.
