General instructions for cleaning and maintenance
Regular cleaning and maintenance of your window and door elements is of great importance to assure their correct functioning and prolonged lifetime. The aluminium construction needs regular maintenance, using non-aggressive cleansing agents, like tepid water with a non-aggressive, pH-neutral (6-8), non-acetose detergent, not containing ammonia.
Hardware parts of the Reynaers Aluminium system should only be replaced by the original parts.
THE BELOW MATERIALS CAN NOT BE USED TO CLEAN YOUR WINDOWS AND DOORS:
• Hard materials such as knives, steel wool, metal scrapers, sandpaper, etc. These will damage the surface of your window -and door elements.
• Aggressive or corrosive cleaning agents should be avoided as they can inflict irreversible damage to the surface treatment of your window and door elements. Instead, use our dedicated range of Reynaers Aluminium care products. An overview of our care products can be found on page 10.
When and how often should you maintain your systems
Regular supervision of the elements is of major importance. The timeframe between these check-ups depends on the installation situation and the amount of window or door movements.
Any possible irregularities in the operation (slowness, unusual sounds, …) which might occur during maintenance must be reported immediately. Windows and sliding doors should undergo regular maintenance to prolong their service life and to ensure their functionality and the conservation of value.
(schools, hospitals,
doors (EN 179/EN1125)
Windows / Sliding systems
Profiles and hardware in non-corrosive environments - and provided that the aluminium elements are exposed to rain - should receive maintenance twice a year. In all other cases: minimum 4 times a year.
Some corrosive environments or other risk factors (e.g. limited rain) may however require even more frequent cleaning to be observed by the end-user.
Examples of such corrosive environments/risk factors are, but are not limited to:
• Near the coast (<10km) or close to estuaria or large rivers (<5km).
• Above water (condensation).
• Within industrial areas, in particular areas with heavy emission of chemicals, fluorides, gasses, and ore materials.
• Exposure to large traffic (motorways, railways, airports).
• Very aggressive environments (e.g. swimming pools, water treatment industry, laboratories, pollution by animals etc.).
Special maintenance is required in case of fireproof doors. For detailed guidelines, we refer to the specific system catalogues of Reynaers Aluminium.
Opening type Use
Overall maintenance
Maintenance of drainage holes
Clean the chamber between the moving and the fixed part every 6 months. If necessary, clear the drainage holes of any blockings.
Maintenance of rails in sliding and lift-slide elements
Dirt and sand might collect in the bottom profile of your sliding or folding door. Clean the gutter(s) every month. If necessary, clear the drainage holes of any blockings. Remove the dirt, dust, grease and graphite annually from the rail with a cloth.
Maintenance of gaskets
Maintenance of hardware and accessories
Clean hardware exclusively with a soft cloth and mild, pH-neutral cleaning materials in diluted form. Remove the dust, grease and graphite annually* from the following areas:
• Window gearing.
• Friction hinges.
• Moving parts of the handles.
• Locks and cylinders, using a graphite pipette and graphite powder.
• Safety device Soft-Close/Soft-Stop for sliding element.
Once a year, apply normal domestic talc to the gaskets (in EPDM) between the moving and the fixed part of the element, or apply liquid silicone (with a cloth), to avoid cracks and deposits. *
WARNING!
• Avoid silicone lubricants. Instead, use a dry cloth and fitting oil to protect the surface and prevent dust collection on the hardware parts.
• Do not lubricate the composite rods or door hinges.
• Never use aggressive acidiferous cleaning materials or scouring agents. These can cause damage to the hardware.
Maintenance of electrical components
The maintenance of motorised sliding systems must happen on a yearly basis, preferably before the winter season. You find a dedicated file with the instructions for motorised sliding systems, “Maintenance check-list”, on the article website under the article of the motor (e.g., 062.7352).
WARNING!
• Maintenance and repair of the motor and/or lock may only be carried out by a qualified professional.
• Motorised sliding windows must never be used as escape routes. There must always be another way of leaving the room. Motorised sliding windows must never be used as fire doors either.
• Make sure children do not play with the control button and/or cannot access the remote control.
• The motor must be able to be disconnected from the power supply for maintenance or repair work.
• Make sure water never enters the motor housing, even during cleaning.
Cleaning and maintenance of windows
The following maintenance operations must be carried out on a regular basis:
Clean the mechanism and remove any traces of dirt. Use a soft cloth and mild, pH-neutral cleaning materials in diluted form.
Check all the components that are important for safety (hinges, extension arms). In particular, the hinges should be checked for damage and/or deformation due to violent impact.
Lubricate the moving parts and locking points as indicated in the diagram (use neutral lubricants). If necessary, carry out adjustments to the mechanism and replace worn-out components to restore the correct functioning of the vent. This operation must be carried out by a qualified professional only. 1 2 3
Locking point Hinges
Cleaning and maintenance of doors
Single & double doors
DOOR LOCKS
Safety-relevant hardware should be checked at least once a year* for wear and tear and a continuous firm fit. Depending on the requirements, fixing screws have to be tightened. The damaged or worn parts should be replaced by original parts by a qualified professional.
All movable parts and locking parts have to be oiled and their working order should be checked. The cylinder can be maintained by using graphite powder.
DOOR HINGES
In general, hinges are maintenance-free and do not need to be lubricated.
DOOR CLOSERS
Safety elements such as door closers must be checked for wear regularly to ensure that they are fitted correctly and securely. Fixing screws must be tightened and any damaged components must be replaced. The frequency depends on opening type and environment, please check specifications on page 3.
Furthermore, the following maintenance tasks must be performed at least once a year (depending on the type of hinged doors and their applications).
• All moving parts on the link arm must be oiled.
• The closer settings (e.g. closing speed) must be checked.
• Smooth operation of the door must be checked.
• In the case of door closers with special functions (hold-open devices / hold-open systems), the legal check, monitoring, and maintenance must be observed.
• Door closers and/or defective parts must be replaced immediately if their proper functioning is no longer guaranteed.
Only cleaning agents without corrosive and damaging components should be used.
Sliding doors
SLIDING ELEMENT
All safety aspects of the hardware, more specifically the fixings (lock, lock keeps, hook keeps and door handles) should be checked regularly. All gear adjustments, especially of the keeps and roller assemblies, the replacement of parts and installation and removing of the vents should be executed by a qualified window expert. Maintenance should be carried out at suitable intervals (see page 3) relative to the amount of use and environmental conditions.
Follow these instructions:
• Check the operation of the components
• Any dust or dirt must be removed from the components as this could affect the smooth operation of the system.
• Clean the mechanism and remove any traces of dirt. Use a soft cloth and mild, pH-neutral cleaning materials in diluted form.
• After cleaning the hardware surface, treat it with silicone and corrosion-free (i.e. non-acidic) oil.
LIFT-SLIDE ELEMENT
To ensure smooth and trouble-free operation, you must carry out the following maintenance tasks at least once a year:
• Lubricate or oil all locking parts.
• Use only clean and non-resinous grease or oil.
• After cleaning the hardware surface, treat it with silicone and corrosion-free (i.e. non-acidic) oil.
WARNING!
The following tasks should only be performed by a qualified professional:
• Replacing the fittings.
• Assembling / dismantling the vents.
