GENERAL SAFETY INSTRUCTIONS
Please be aware that our General Assembly Regulations must be adhered to.
They can be viewed under www.k2-systems.com/en/downloads/product-information.html
In general, the following applies:
¬ Systems may only be installed and put into use by people who can ensure the proper carrying-out of the
work due to their technical suitability (e.g. training or occupation) and/or experience.
¬ Before assembly, it must be checked that the product meets the local static requirements. For roof systems,
the load-bearing capacity of the roof has to be checked in principle.
¬ National and local building regulations, standards and environmental regulations are always to be adhered
to.
¬ Work safety and accident prevention regulations and corresponding standards and regulations of occupati-
onal associations are to be adhered to! In particular, it is to be ensured that:
- Safety clothing is worn (especially safety helmets, work shoes and gloves).
- For work on roofs, the regulations for working on roofs are to be adhered to (e.g. use of anti-fall
guards, scaffolding with arrestor equipment from an eaves height of 3m etc.)
- Presence of two people is vital for the entire course of the assembly, so that swift help can be ensured
in the case of an accident.
¬ K2 mounting systems are constantly being developed further. Because of this, assembly procedures can
change. Therefore, before assembly, always check that the assembly instructions are up-to-date under
www.k2-systems.com/en/downloads/product-information.html. We can also send you the latest versi-
on on request.
¬ The assembly instructions of the module manufacturer are to be adhered to.
¬ Earthing must be ensured, use lightning arrestor clamp if necessary.
¬ During the entire assembly time it is to be ensured that at least one copy of the assembly instructions is
available on site.
¬ In the event of non-adherence to our General Safety Instructions and if competitor’s parts are built in or
attached, K2 Systems GmbH reserves the right to refuse liability.
¬ With disregarding our general installation and assembly instructions and not using all system components
and assemblies according to these instructions as well when components are used, which were not obtai-
ned from us, K2 Systems is not liable for any resulting defects and damages. Warranty is excluded in such
cases.
¬ If all safety instructions are adhered to and the system is correctly installed, there is a product warranty
entitlement of 12 years! Please read out Terms and Conditions of Warranty which can be viewed under
www.k2-systems.com/en/downloads/product-information.html. We can also send them to you on request.
¬ The dismantling of the system takes place according to the assembly steps, in reverse order.
¬ K2 components made of stainless steels are available in different corrosion resistance classes. In every
case,the expected corrosion exposure of each structure or component must be checked.

IN GENERAL:
Please carefully read through all the steps first to ensure safe and correct assembly of the system. The required
material is listed for each step. Should you have any problems during assembly or questions relating to the system
please contact us on our
SERVICE HOTLINE: [phone]
IMPORTANT:
¬ The grounding must be prepared on site and carried out in accordance to the respective
national regulations.
¬ If the the trapezoidal sheet is fixed with calottes, never connect the MultiRail directly with the calottes
¬ The General Installation Instructions must be adhered to.
These can be found at: www.k2-systems.com/en/downloads/product-information.html
¬ This system can be installed on all standard flat roofs with pressure-resistant substrates and a roof pitch of up
to 5 degrees. The elevation angle is 10°.
¬ Minimum distance to roof edge: 500 mm.
¬ The K2 S Dome S1000 system is suitable for modules with a frame height of 34 - 50 mm.
This system is not suitable for thin-film modules.
¬ Modules with an area of up to flat of 2m2and a width of 950 to 1050 mm can be used.

MOUNTING THE MULTIRAIL
MEASURING THE RAILS
Use two self-tapping screws to fasten the MultiRail rail to
the center of the crest. To do that the rail has to be pre-
drilled with 2 holes with 6mm diameter each, an appropri-
ate EPDM strip material has to be used to seal between the
trapezoidal sheet and the rail. Minimum width of the crest:
22mm. The EPDM seal under the rail may be compressed
to a maximum of 50%. The seal of the screw should not be
too tightly compressed.
Materials required: K2 MultiRail 25, self-tapping sheet-metal
screws
The horizontal spacing X of the MultiRail rails is defined
by the dimensions of the modules and their maximum
clamping range. As a rule the recommended spacing is half
the length of the module. In individual cases the assembly
instructions of the modules must be followed with respect
to the clamping range.
Use a chalk line to align the rails in a row.
