The Electronic IF-171 Door Handle
2.5.3 Cleaning Tips
The devices are made of top quality stainless steel. This steel grade is extremely durable and has a
smooth, matt-finished surface and a high resistance against wear and tear, corrosion and abrasion.
Please observe the following instructions to avoid damaging the naturally formed passive protective
coating when handling or cleaning stainless steel products.
Do not use any ferritic auxiliaries such as steel wool, brush or abrasive paper to repair and rework
defects on the steel surface. These materials can damage the protecting passive layer that has been
formed on the steel surface. It is there where the surface begins to corrode.
Professional installation and the use of adequate fasteners prevent a natural, atmospheric exposure
corrosion. Do not use screws that were made of or are anodized with less noble metals as fasteners.
Stainless steel products must be cleaned at regular intervals if you want to prevent impurities or rust
depositing on the surface.
Simply cleaning the surface using adequate detergents and water for
thorough rinsing is sufficient
.
Besides regular cleaning, we recommend applying an additional protective coat on the surface using
adequate, commercially available preservative agents or care oil.
Paints, acids and lye may damage the surface of the product. Damages of this type can
result in malfunctions and even failure of the product.
This may affect the security of your
organization.
This product must therefore not be in contact with the aforementioned
substances.
