1.10 Limitation of liability
All information and instructions contained in this document have been
compiled in consideration of the applicable standards and regulations, the
latest developments in technology and many years of knowledge and
experience.
The hardware manufacturer assumes no liability for damage caused by:
■Failure to comply with this document and all product-specific documents
and other applicable directives (see the chapters entitled “Security” and
“Stipulated use”).
■Improper use / misuse (see the chapters entitled “Security” and “Stipu-
lated use”).
■Insufficient invitation to tender, non-compliance with installation specifi-
cations and non-compliance with the application diagrams (where
available).
■Increased contamination.
Claims made by third parties against the hardware manufacturer on account
of damage resulting from misuse or failure to comply with the obligation to
give instructions on the part of hardware dealers, window, door and balcony
door manufacturers and building element dealers or the builder are passed
on accordingly.
The obligations agreed in the delivery contract, the general terms and condi-
tions, the hardware manufacturer’s terms and conditions of delivery and the
legal provisions applicable when the contract was concluded shall apply.
The warranty only covers original Roto components.
We reserve the right to make technical changes as part of improvement to
performance characteristics and further development.
1.11 Preserving the surface finish
ATTENTION
Surface treatments may cause property damage.
Surface treatments (e.g. painting and varnishing) on elements can
damage components or prevent them from working properly.
uFor masking, only use adhesive tape that does not damage
the paint coats. Consult the manufacturer if in doubt.
uProtect components against direct contact with the surface
treatment.
uProtect components against contamination.
General information
Limitation of liability
12 · 11 / 2020 · IMO_539_EN_v0 Roto FS Kempton Subject to change.
ATTENTION
Using incorrect cleaning agents and sealing
compounds may cause property damage.
Cleaning agents and sealing compounds may damage the
surfaces of components and gaskets.
uDo not use aggressive or flammable liquids, acidic cleaners or
abrasive cleaners.
uOnly use mild, pH-neutral cleaning agents that have been
diluted.
uApply a thin protective film to the components, for example
using a cloth soaked in oil.
uAvoid aggressive vapours (e.g. produced by formic acid,
acetic acid, ammonia, amine compounds, ammonia
compounds, aldehyde, carbolic acid, chlorine, tannic acid)
around the element.
uDo not use any acetic acid-crosslinking or acid-crosslinking
sealing compounds or those with the aforementioned constit-
uents as both direct contact with the sealing compound and
its fumes can corrode the surface of the components.
ATTENTION
Contamination may cause property damage.
Contamination prevents components working properly.
uRemove deposits and contamination caused by construction
materials (e.g. plaster, gypsum).
uKeep components free of deposits and contaminants.
ATTENTION
(Permanently) damp room air may cause property
damage.
Damp room air can lead to mould growth and corrosion caused
by condensation.
uProvide adequate ventilation for components, particularly
during the construction phase.
uIntensively air out the room several times per day by opening
all elements for approximately 15 minutes. If intensive airing is
not an option, place the elements in the tilt position and
provide airtight masking inside the room, e.g. if there is fresh
screed that cannot be walked on or must not be exposed to
draughts. Discharge any humidity present in the room air to
the outside using condensation dryers.
uEstablish a ventilation plan for more complex construction
projects if necessary.
uProvide adequate ventilation during holiday periods as well.

2.5 Basic safety information
The following hazards may arise when handling the product:
2.5.1 Installation
Incorrect installation poses an immediate risk of death or serious
injuries.
Incorrect installation or assembly of hardware can lead to hazardous situa-
tions or property damage. Depending on the height of the fall, this can result
in serious to life-threatening injuries and glass breakage.
uOnly use hardware combinations that have been approved by the
hardware manufacturer.
uOnly use original accessories or those that have been approved by the
hardware manufacturer.
uAlways have installation performed by a specialist company.
Heavy loads pose a risk of injury.
Lifting and carrying heavy loads may lead to injuries in the event of a fall or
physical overexertion.
uNote the applicable accident prevention regulations.
uTransport heavy loads with two people and use suitable transportation
means (such as an industrial truck).
Physical strain may cause damage to health.
Moving heavy loads for extended periods leads to physical injury in the long
term.
uWhen carrying and lifting by hand, comply with a maximum weight of
25 kg for men and 10 kg for women.
uCarry and lift even small loads with an ergonomically correct posture.
2.5.2 Use
Falls from open windows and balcony doors present an immediate
risk of death and pose the risk of serious injuries.
Opened sashes of windows and balcony doors create a danger zone.
Depending on the height of the fall, this can result in serious to life-threat-
ening injuries and glass breakage.
uTake care when in the vicinity of open windows and balcony doors.
uKeep children and anyone unable to understand the risks away from the
hazardous area.
Trapping body parts in the opening between sash and frame may
lead to serious injuries.
Gripping between the sash and frame when closing windows and balcony
doors poses the risk of crushing injuries.
uWhen closing windows and balcony doors, never grip between the sash
and frame and always exercise caution.

uKeep children and anyone unable to understand the risks away from the
hazardous area.
Opening and closing sashes improperly poses the risk of injury and
property damage.
Incorrect opening and closing of sashes can result in serious injuries and
substantial property damage.
uWhen moving the sash, ensure that it will not slam against the frame or
other sashes once fully opened or closed.
uEnsure that the sash is slowly guided by hand throughout its entire
movement range, until it has been brought into a fully closed or opening
position.
uWhen closing a sash and locking the hardware, the gasket counter force
must be overcome.
uIf no opening restrictor is used, the sash may close in an uncontrolled
manner. Ensure that the sash does not strike any obstacles.
Misuse poses a risk of injury and property damage.
Misuse can lead to hazardous situations and may destroy the hardware,
frame materials or other individual components within the windows or
balcony doors.
