Transport and handling instructions

b
Caution!
Collectors may be damaged by incorrect
storage!
If the flat collector is not stored correctly,
moisture can penetrate and cause damage in
the presence of frost.
> Always store the flat collectors in a dry
place and protected from the elements.
> Always transport the flat collector lying flat to ensure
optimum protection.
> The load can be transported to the roof more easily
using a construction site crane or automatic crane. If
this equipment is not available, an inclined hoist can
be used. In either case, it is essential to guide the flat
collector with additional ropes to prevent swinging or
tilting to the side.
> If motorised equipment is not available, pull the flat
collector on to the roof by sliding them up lean-to lad-
ders or scaffolding boards.
3.2

Installation instructions

> Observe the maximum permissible substructure load-
ing and the required distance from the roof edge in
accordance with EN 1991.
> Attach the flat collectors carefully to ensure that the
brackets can safely withstand the tensile loading that
occurs during storms and adverse weather conditions.
> Align the flat collectors to point south if possible.
> Remove the sun protection film on the flat collectors
only after the solar energy system has been started
up.
> For work on the solar circuit, use only hard soldered
joints, gaskets and compression fittings or press fit-
tings that have been approved by the manufacturer
for use in solar circuits and at correspondingly high
temperatures.
> Thermally insulate the pipes in accordance with the
Heating Systems Ordinance (HeizAnlV), making sure
that the thermal insulation is temperature resistant
(175 °C) and UV resistant.
> Fill the solar system only with Vaillant ready-mixed
solar fluid.
