Cleaning and care instructions
7.1
Stainless steel outer wall terminals (M-WRG-II ES)
NOTICE
The thin and transparent passive coating on the surface protects the stainless steel
against corrosion. 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
complete.
►
Remove all adhesive residues that remain on the outer wall terminals when you
remove the protective film.
►
Clean the outer wall terminals after installation using a soft, lint-free cloth and stain-
less steel cleaner.
► Remove any flash rust that is already present using a soft, lint-free cloth and stainless
steel cleaner.
NOTICE
Corrosion caused by flash rust is not covered by the warranty.
► 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 and before it hardens from
the surface of the outer wall terminals.
