for flat collectors on flat roof or foundation.
1. Introduction
Lightning protection installation
In the case where the height of the collector installation exceeds 20m and the building is not
e uipped with lightning protection, all of the electrically conductive elements should be
connected to an earth rod (minimal earth rod cross-section – 16mm
2
), and then to the
e ualizing potential.
When the collector installation height does not exceed 20m, the lightning protection system
is not re uired.
If the building is e uipped with the lightning protection, the connection of the solar
installation with the lightning protection should be checked. This procedure should be
performed by an electrician.
Recycling
Worn out solar collectors can be returned to the manufacturer.
The manufacturer will dispose the returned collectors in an environmentally sound manner.
2. afety during installation
Before starting the installation it is necessary to get promptly acquainted with the
safety precautions!
2.1 Notes included in the instruction
The installation instruction includes important information concerning safety and proper
positioning of the collectors on the roof as well as the proper execution of the hydraulic
connection.
The drawings and the information included in the instruction apply to a vertical and
horizontal installation of collectors.
The installation of collectors described in the instruction may only be performed by
ualified persons who have expertise in a range of gas and water installations.
Upon the completion of works, the installer should hand over the installation instruction to
the customer and present in a comprehensible manner the principles of operation and Note
essential to a proper operation of the solar installation.
2.2 Application
This instruction includes a description of an installation set for installation of collectors on a
flat roof or a foundation with the inclination ranging from 30°
to 75°.
The installation set shall be used only for solar collectors installation, it must not be used
for installation of other devices on the roof. The installation of solar collectors only on a
supporting structure guarantees safety.
Collectors installed on the ground must be attached to the ground by the means of
foundation and transitional construction (Not included in the standard installation set).
The minimum distance between the bottom edge of a collector to the ground surface must
be min.40cm.
