2. CLEANING & MAINTENANCE FREQUENCY VELFAC 860 Bi-fold doors are easy to use and maintain but in order to ensure maximum lifespan it is important to inspect and service individual parts regularly. The correct cleaning and maintenance of your bi-fold doors will keep them looking good and ensure they will resist even the harshest weather conditions for years to come. The following cleaning and maintenance instructions should, as a minimum, be carried out according to the frequency below. Please note that cleaning and maintenance intervals may vary based on the way of operating the bi-fold door and on the environment. Your bi-fold doors will need more regular inspection and maintenance if they are installed in a harsh environment, such as a marine or industrial location or in areas of high internal humidity or if they are exposed to strong sunlight on south facing facades. You can find more information on the different cleaning and maintenance subjects on the following pages.

3. MAINTENANCE 3.1) General The external cleaning effect is generally regulated by normal rainfall which removes harmful deposits. Internally it is important to remove fingerprints and in coastal or industrial areas where the concentration of chlorides and sulphur dioxide can be higher we recommend cleaning with a damp cloth. To remove fingerprints: wet cloth or leather with a mild detergent solution. For bright annealed and polished mirror surfaces: chloride-free glass cleaner. For stubborn stains, lime scales and slight discoloration: household cleaning detergents, iron-free cleaning sponges, rinse with clear or demineralized water and dry rub the surface. For oily and greasy stains: alcoholic detergents and solvents such as white spirit or acetone. Brushed and polished surfaces: always wipe in the direction of the grain/texture. 3.2) Seals & Connections Joints Regular check if the seals fit properly and are in good condition. Annual greasing of the seals with silicone spray. Annual inspection of sealing joints from frame to masonry. If necessary, repair or replace sealant due to cracking or delamination. 3.3) Hinges & Locking All hinges and locking devices are of the low maintenance type and are almost wear-free. To preserve the value of your investment check the surfaces, hinges, locking systems etc. on a regular basis for full functioning. We recommend regular lubrication of the hinges with suitable lubricants, please check frequency table at page 4. 3.4) Carriage Annual oiling of all movable parts and locking points (hinge, hinge bearing, rotating bands, carriages, guide rollers and gears) with an acid and resin free grease. Annual check of the opening handle and seal. If necessary tighten bolts in handle rosette. Weekly clear debris and clean the track. Your VELFAC 860 bi-fold door was installed and adjusted carefully. Extreme stress or movements in the surrounding structures can require read justment over the years. Contact your installer of the bi-fold door to make these adjustments. 5

4. CLEANING Before commencing any task, ensure that you have received the appropriate health and safety literature from the supplier and fully understand it. If in doubt, seek further advice. 4.1) Aluminium The panels are externally and internally made from aluminium with a powder coated finish. Cleaning will be needed at least once a year with a soft cloth or soft bristle brush and luke warm water with a few drops of mild detergentt and a preservative as car wax (for stubborn stains use a car polish), Black stripes from gaskets will be harder to remove, if allowed to sit for long periods and materials such as paint, wet concrete etc. must be washed off immediately, A scratch will not affect the durability of the sash as the aluminium will form a natural layer of oxide. Scratches in the surface treatment can be repaired with repair lacquer, but differences in colour may occur If atmospheric pollution has resulted in heavy soiling of the coating, then nothing stronger than white spirit should be used. Abrasive cleaners or chemical cleaners containing ketone, esters or alkalis should not be used. 4.2) Glass Clean regularly with water, sponge or cloth, Use of glass cleaners, without abrasives components, is possible, Clean with alcohol, acetone and benzine to remove stubborn stains. 4.3) Seals & Connections Joints Annual cleaning of the gaskets with water and mild detergent. 4.4) Stainless Steel Handles Stainless Steels are inherently corrosion resistant materials that do not need additional surface protection to enhance their appearance and durability. Some routine maintenance and cleaning is needed to keep stainless steel surfaces in good condition so that the aesthetic appearance and corrosion resistance are not compromised. In this respect, stainless steels are no different to other construction materials such as glass, plastics or coated steels, which are never maintenance free throughout the life of a building. Follow the below guidelines on efficient, cost-effective cleaning that will allow them to take advantage of the corrosion resistant properties of stainless steel. Cleaners that should NOT be used on stainless steels include: - chloride-containing cleansers, especially those containing hydrochloric acid, - hypochlorite bleaches should not be used on stainless steels; if applied acciden tally or spilt on stainless steel surfaces, should be rinsed off immediately with liberal amounts of fresh water, - silver-cleaners must not be used on stainless steel. 6

4.4.1) Initial cleaning of handles before handover The initial cleaning is carried out before the building is handed over to the owner. If the stainless steel parts have been protected adequately then simple maintenance cleaning at the hand-over stage will probably be sufficient. An adhesive plastic film during fabrication, transport and assembly. Is often used to protect stainless steel parts. Although providing excellent protection against damage and soiling, some plastic films deteriorate on exposure to the ultraviolet radiation in sunlight and which can make them difficult to strip. The film adhesives can also stick to the stainless steel surface. Protective plastic films should be removed as soon as they are no longer needed for protection during construction and installation, starting at the top of the building and working downwards. Mortar and cement splashes can be treated with a solution containing a small amount of phosphoric acid. Rinse with water (preferably deionized water) and dry. Deionized water reduces the risk of water staining marks. Proprietary products are available from specialists finishing companies. Never allow mortar removers or diluted hydrochloric acid to be used on stainless steel. If they have accidentally been applied to or spilt over the stainless steel, rinse generously with fresh water. Building contractors and tradesmen are not always aware of how dangerous proprietary building mortar removers containing hydrochloric acid are to stainless steel components. This should be stressed. If possible, the sequence of operations should be changed so that any ceramic tile fixing and cleaning is completed before neighbouring stainless steel components are installed. Iron particles picked up from tools or from contact with structural steel, scaffold tubing etc. must be removed immediately. Steel dust particles created during operations such as welding, cutting, drilling and grinding of carbon (no stainless) steel will rust quickly. Besides corroding themselves, these particles can locally break the self-healing passive film of stainless steel resulting in pitting corrosion in spite of their normally good corrosion resistance. At an early stage, light deposits can be removed mechanically using nylon pads, such as the Scotch-Brite type used in the kitchen. Alternatively the contamination can be removed with a proprietary stainless steel cleaner containing phosphoric acid. If pitting attack has occurred, depending on its severity, acid pickling treatments or mechanical rectification will be needed to restore the surface. Pickling agents in paste form are available for localized, on-site application. Care must be taken to use these products in accordance with the supplier s directions so that there is a safe system of work and the relevant legislation on environmental protection is adhered to. 7

While restoring the corrosion resistance of the surface, pickling may change the surface appearance of the steel. Further mechanical or chemical treatments may be necessary to restore the original surface finish. It is therefore advisable to avoid contamination, in the first place by either protecting the stainless steel parts, whilst other work is being done or by installing them after other operations that could cause contamination have been completed. 4.4.2) Maintenance cleaning of handles Cleaning of interior handles should be done before there is a visible build up of soiling or finger-marking, so that the effort and cost of cleaning is minimised along with the risk of marking or altering the appearance of the surfaces. Exterior handles may be exposed to a wider range of potentially more aggressive environments as a result of contact with: marine atmospheres, environments laden with industrial pollutants, salt spray from road de-icing salt, atmospheric dirt and traffic film. It is a good practice to clean the stainless steel handles at the same frequency as the glazing. Depending on the severity of soiling and deposit build up, routine cleaning frequencies of 6-12 months for light soiling and 3-6 months for heavy soiling or environments such as those listed above is advisable. A stainless steel cleaner containing phosphoric acid will remove this form of contamination. Any damage or scratches to the finish should be professionally repaired as soon as possible using recommended touch up coating. On external applications, such as facades, rainfall can normally be expected to wash off accumulations of dirt and other deposits efficiently, depending on the amount of exposure of the elevation. Special attention should be given to sheltered areas during routine cleaning to ensure that accumulations of airborne contaminants are removed. This is particularly important in marine and industrial environments, where build-up of airborne chlorides or sulfur oxides (SO x ) can result in localized corrosion, if not effectively removed. On interior applications, finger marks can be an issue. There is a wide range of finishes available for stainless steels, many of which are particularly suitable for use in heavily exposed (high traffic) public areas. 4.4.3) Appropriate Cleansers To remove fingerprints and other marks from architectural finishes, soapy water or a mild detergent are usually safe and successful. Proprietary spray cleaners are available, which combine ease of cleaning with a light film that produces an even and smooth lustre. These spray cleaners remove existing fingerprints and leave the surface in a condition that reduces the 8

tendency for fingerprints to show in subsequent service. After applying the spray to the surface, polish with a dry cloth. Your nearest national stainless steel development association should be able to advise on products locally available. A full list of BSSA members can be found on www.bssa.org.uk. Mirror-polished stainless steel can be cleaned with glass cleansers. These products should be selected chloride-free. For more stubborn stains, mild household cream cleansers should be effective. This should also be suitable for cleaning off watermarks and light discolouration. After cleaning, remove the residues with (preferably deionized) water (available in supermarkets, e.g. for steam ironing or car batteries) and dry to avoid streaking and water marks. Scouring powers should not be used as these products can leave scratches on stainless steel surfaces. Severe oil and grease marks can be removed with alcohol based products, including methylated spirit and isopropyl alcohol or other solvents such as acetone. These products are not a corrosion hazard to stainless steel. Care is needed with solvents to avoid spreading the staining on the stainless steels, which can then be difficult to fully remove. It is advisable to apply clean solvent several times with a clean, non-scratching cloth, until all traces of the partially dissolved oil / grease are removed. Paint and graffiti can be treated with proprietary alkaline or solvent-based paint strippers. The use of hard scrapers or knives should be avoided as the underlying stainless steel surface may become scratched. Heavily neglected surfaces can be treated with metal polishes, such as those for cleaning chromium-plated items (e.g. automotive trim). Furthermore, polishes used for re-finishing car paint can be considered. Care must be taken as highly polished surfaces may become scratched with these cleaners. Alternatively, use a proprietary stainless steel cleaner containing phosphoric acid to remove contamination, rinse with deionized water and dry. It is advisable that the entire surface of the component is treated so that a patchy appearance is avoided. 4.4.4) Cleaning utilities A damp cloth or chamois leather will usually be suitable for removing normal soiling, fingerprints, etc. For more stubborn dirt, nylon pads such those known as Scotch-Brite pads are usually satisfactory. Non-stainless steel based scouring pads, cleaning wool or wire brushes must not be used on stainless steel. Apart from scratching the surface, these pads can leave carbon steel deposits on the stainless surface, which can subsequently develop into rust spots, if the surface becomes wet. Soft nylon brushes can be used for cleaning stainless steel with patterned finishes. Non-stainless steel wire brushes must not be used. 9

Where water has been used for cleaning or rinsing, wiping the surface dry to prevent watermarks, especially in hard water areas may be advisable. The use of deionized water will prevent the formation of hard water staining. To avoid cross-contamination from iron particles, ensure that cleaning utensils have not been used for ordinary (i.e. carbon) steel before. Cleaning materials for use on stainless steel items should preferably be reserved exclusively for that purpose. 07.58-01.18 2018 VELFAC LTD VELFAC and VELFAC logo are registered trademarks used under license by VELFAC Group.
