1. Introduction
Lightning protection
In case the height at which the collectors are to be installed exceeds 20 metres
and a building is not equipped with the lightning protection it is necessary to
connect all electrically conducting elements with an earth rod (minimal earth
rod cross-section –16mm2), and then with a compensating potential.
In case the height at which the collectors are to be installed does not exceed
20 metres it is not necessary to provide the lightning protection.
If the building is equipped with the lightning protection it is important to check
the connection of the solar system to the lightning protection. That task should
be performed by an electrician.
Recycling
Completely used up solar collectors can be returned to the manufacturer.
The returned solar collectors shall be utilized by the manufacturer in the way
which is the least burdensome for the natural environment.
2. Safety during installation
Before commencing the installation work it is necessary to immediately
get acquainted with the safety tips!
2.1. Notes included in the instruction.
