Maintenance and servicing instructions

General
External building parts are not only subject to the weather, but also increased stress caused by smoke, industrial fumes and aggressi-
ve airborne dust. In conjunction with rain and dew, deposits of these substances may affect the surface and change the appearance.
External parts must therefore be cleaned (at least twice annually or more frequently depending on the degree of contamination) to
avoid possible settling of deposits. The sooner you remove dirt from the surface, the easier it is to clean. Observe the safety inst-
ructions and instructions for use of the respective servicing and cleaning products. When cleaning do not use a material with an
unknown composition. If you are not certain about the effect of the cleaner , then test it first by cleaning a visually unimportant,
non-exposed portion of the component.
Fittings
All fittings must be regularly checked for tightness and wear. Attachment screws must be tightened and defective parts replaced as
required. In addition, at least once a year, all moving and sliding fittings must be lightly greased with fitting grease. Only servicing
and cleaning agents that do not affect the corrosion protection of fittings should be used.
Glass surfaces
Dirty glass surfaces can be cleaned using water and a sponge or cloth, etc. Commercially available non-abrasive glass cleaners (such
as Ajax, Pril, etc.) can be added to the water. Stubborn stains such as paint or tar splashes should be removed with methylated
spirits or white spirit.
Caution!
Do not use alkaline caustic solutions, acids, and fluoride-containing detergents to clean glass surfaces.
Caution!
A suitable protective film should be used to protect the glass surface against mortar spattering, cement slurry, sparks or weld sputte-
ring from partitioning screens and stone-facade acidic-cleaner..
Seals
All seals must be cleaned and lubricated at least once a year to ensure good functioning. For this purpose we recommend the use of
a seal care product. The care product maintains the suppleness of the seal, thus preventing premature brittleness. Ensure that the
seals are not damaged and do not come into contact with solvent materials.
Aluminium surfaces
Anodizing and powder coating is a highly durable and decorative finishing for aluminium components. To maintain the decorative
appearance of such components for decades, the surfaces need to be regularly maintained by means of cleaning twice a year.
Cleaning anodized surfaces
Cleaning of the surfaces must not take place in direct sunlight, the surface temperature must not exceed 25°C. Use only neutral pH
cleaners such as normally diluted washing up liquid. Abrasive or scouring materials must not be used to clean heavily soiled, ano-
dized surfaces - cleaning pastes are available.
