5.1 Processing instructions
Friction stay
Positioning and rebate clearance
■
The Roto FS Kempton friction stays are designed to be installed between two parallel, fixed surfaces with a
correct rebate clearance distance.
■
The retraction mechanism of the friction stays must be placed in the inner corner of the frame rebate unless
adaptation is required.
■
If the profile does not have any parallel surfaces for mounting the scissor stays, use packer strips or adapters to fill
the gap and adapt the scissor stay space in accordance with requirements
■
The installation space for the friction stays must meet the requirements defined in this document.
Sash formats
■
Refer to the specifications of the friction stays for the maximum permitted sash heights and widths.
■
Do not exceed the maximum permitted sash weight
3.6 “Application diagrams” from page 26
The component with the lowest permitted load bearing capacity determines the maximum permitted sash weight.
■
Before using electronic data records and implementing them in window fabrication programs in particular, check
that they match the specifications, application diagrams and component assignments.
Limiting the opening width
■
Additional hardware components (such as opening restrictors) may be required to hold sashes in a specific
position.
This applies particularly to large formats, very small opening angles (10° or less) or in areas exposed to wind.
■
Windows with Top-Hung friction stays of sizes 22", 24" and 26" are equipped with an internal opening width
restrictor. An additional opening restrictor can be installed if necessary
3.6 “Application diagrams” from page
.
■
Installation or maintenance work may require opening angles that exceed the nominally permitted opening angles
of the friction stays. These opening angles must not be used in regular operation. For this reason, take suitable
measures (such as integrated opening restrictor or additional opening restrictor) to limit the sashes to the
maximum permitted opening angle.
Specifications from profile manufacturers
■
The window and balcony door manufacturer must comply with all specified system dimensions (e.g. gasket gap
dimensions or locking distances).
■
They must continue to ensure and check this on a regular basis, especially when new hardware components are
used for the first time, during production and on a continuous basis, up to and including window installation.
INFO
The hardware components are always designed in such a way that any system dimensions affected by the
hardware can be adjusted. The hardware manufacturer shall not be liable for any additional expenses
incurred if a deviation from these dimensions is not discovered until after the windows have been
installed.
Combining hardware
■
Windows and balcony doors for wet rooms and those for use in environments with aggressive, corrosive constit-
uents in the air require hardware that meets special requirements.
■
The resistance of windows and balcony doors to wind loads when they are closed and locked depends on the
individual design of the windows and balcony doors. The hardware system is capable of handling wind loads
specified by legislation and standards (for example in accordance with EN 12210 – especially test pressure P3).
