GENERAL REMARKS
The installer always has to check whether the rubber protection (provided underneath the basic unit) suffices when instal-
ling onto a soft of half-soft underground. The installer also has to check the compatibility of the rubber protection with the
roof surface.
For the following installations, special instructions have to be kept in mind (these specific versions can be delivered on
demand):
•
In an aggressive environment: all materials must be SS with the right specifications to determine the aggressive sub-
stances.
•
In sea salt environments: use anodized aluminium or SS.
Special attention to roofs with a pitch in E-W direction and to roofs that easily move up and down (e.g. as a result of vibrati-
ons from wind load or other causes):
•
Without extra connections in N-S direction, the installation can tend to move downwards irregularly.
•
In cases where you are dealing with roofs which have a negative and/or positive pitch, we recommend to make a con-
nection at the roof-ridge.
•
For roofs with a pitch in N-S direction and which have a negative and a positive pitch, we recommend to make a
•
connection at the roof-ridge.
•
If in doubt, contact a specialized structural design agency.
Clamps:
•
Only use clamps that the module manufacturers allow and/ or advise.
•
Always clamp with the correct torque (max 9-11 Nm).
Special attention for installations on roofs in extreme circumstances:
•
In the following situations/circumstances, the mounting frames of Allimex are not suitable unless there is a written
acknowledgement of Allimex (concerning a specific project):
* Roof height >20m
* Roof pitch PVC roofs >3°
* Roof pitch non-PVC roofs >4°
* Places where nearby buildings of other objects cause a wind-tunnel effect or increased wind speed
Contamination of the roof skin can lead to a lower friction coefficient, which means that more ballast has to be provided or
(extra) mechanical connections have to be provided, to prevent sliding.
Edge zone:
The installer always needs to keep the minimal edge zone, which is described in de applying standards, free. An example of
such a standard is the NEN7250 but this standard is however not limitative.
Installers should always provide sufficient ballast specific to individual installations. In case of doubt a specialized
ureau should always be consulted.
Always provide sufficient East-West connections.
It is the responsibility of the installer to check whether the panels can be clamped in the way (on the short or long side,
position of the clamps, etc.) that is shown in this manual. If this is not the case, Allimex can in no way be held responsible
for any damage, in whatever form. Allimex can never be held liable if during installation materials are used that are not
supplied by Allimex.
The warranty conditions regarding the mounting frames of Allimex are available on demand. The installation manual should
be observed strictly, otherwise all guarantee agreements will lapse.
The installer is responsible for using the necessary personal protective equipment.
Allimex maintains the right to edit the installation manual at any time. It’s the responsibility of the installer to follow the
latest version, which is the only valid one. The latest installation manual is always available on demand.
