General information

This information has been created with the purpose of providing guidance to building contractors, owners, and other users regarding the storage, maintenance and cleaning of ironmongery products. Having chosen to apply high-end quality products, it is critical that these products are stored and maintained in the correct manner to ensure optimum benefit for their useful lifetime.

Storage
All products are carefully boxed prior to delivery to safeguard against damage during transport. Once the parts have reached their destination it is vital that all fittings are stored in a dry place until mounting. When they have been mounted, care must be taken to ensure that all fittings are adequately protected, until construction is complete.

Maintenance
Lever handles
If instructions are followed to the letter when the lever handles are mounted , there will be no need for adjustment; however, the tension of the fastening of all lever handles should be checked in connection with the annual inspections. Any fastenings that have come loose must be tightened.

Pull handles
Pulls should be checked to ensure correct mounting of the fittings and tightening of any neck screws used. If it is possible to move the pull, such movements will damage the surface of the door and cause instability of the pull leading to possible malfunctioning during use.

Cleaning
• It is essential to clean stainless steel and brass regularly
• Start by washing the surface with soap water or a mild cleaning agent
• Do not forget to rinse off the cleaning agent with pure water
• As a final step, dry/polish the object using a soft, dry cloth. In aggressive environments, such as off-shore or maritime environments and bathing or swimming facilities, it is particularly important to ensure regular cleaning

Discoloration
Any spots that may appear on the surface are not caused by the stainless steel, on the contrary they are produced by impurities in the water, air or cleaning agents that have been insufficiently rinsed off the surface.
• Spots can be avoided by careful cleaning
• Any discolorations or spots can be removed using a polished agent for stainless steel or liquid scouring-powder
• Again, as a final step rinse carefully with pure water and then polish the object with a soft, dry cloth

Do NOT use the following!
• Regular scouring-powder
• Steel wood
• Highly abrasive materials

Surface
With today’s environments the demands to the material properties of a product are considerable. Products must be able to withstand diverse atmospheric conditions, such as heavy air pollution, high humidity and maritime environments. In addition to this, products must allow cleaning with effective cleaning agents and, from an optimal point of view, offer non-allergic properties.

Material characteristics
stainless steel
Stainless steel is well known for the following two properties; resistance to corrosion and a modest need for maintenance. The corrosion resistance of stainless steel is provided by a thin hard-wearing film of a passive but stable chromoxide. This film is inactive, invisible, with extremely adhesive properties and self-repairing so that the steel is given the best possible protection. If the film suffers damage or is removed, it is automatically restored provided the oxygen in the atmosphere is not prevented from reaction with the chrome in the steel. To ensure this it is necessary to clean regularly. The purpose of the cleaning is to restore the appearance of the original surface, protect against corrosion and ensure hygienic conditions.

Brass and nickel plated
Lever handles made of brass with a polished or a nickel-plated surface are more affected by high variations of temperature and environment than lever handles made from stainless steel, as brass is a softer material. Lever handles with a nickel-plated surface have a harder surface than the polished brass lever handles, which can cause cracks in the surface when exposed for high variations of temperature and environmental fluctuations. For lever
handles made from brass or stainless steel the same rules regarding cleaning will apply.

Wood
During production the wooden lever handles have been “sealed” with a thin PU varnish that penetrates into the grains. The PU varnish is mixed oil on a turpentine base that hardens and gives a hard-wearing surface. Hardness in end-wood; 78-83 Mpa. By daily use and exposure to all kinds of weather, the lever handle may over time come to look a bit “worn”. This can be fixed by regularly applying a vegetable oil with a soft cloth. The excess oil needs to be dried off. (In case the layer of oil is used up and the lever handles have not been given aftercare, the wood will still
be fairly protected due to the original consealant).
