FOR THE INSTALLER
14
Assembly
The solar collector must be fitted by specialist personnel.
Use only the assembly material supplied with the solar
collector. The supporting framework and all masonry or
brickwork fixing points must be checked by a person
expert in static loading, and must be suitable for the
nature of the installation site.
Static load
The solar collector must only be installed on roofs or
frames that are strong enough to support its weight. The
strength of the roof or frame must be verified on site by a
person expert in static loading before the solar collector
is installed. During this process, it is important to verify
the suitability of the supporting frame to hold the screw
fasteners that fix the solar collector in place. An expert in
static loading must verify that the entire frame complies
with relevant standards, especially in areas liable to snow
and areas exposed to high winds. Conditions (gusts of
wind, formation of wind vortices, etc.) at the point where
the solar collector is to be installed must be carefully con-
sidered since these can increase the loads on the sup-
porting structure. Allow for a maximum permissible total
load on each collector of 850 Pa (possible in the event of
a peak wind speed of 130 km/h).

Once you have removed the outer packaging, proceed
as follows to unpack and handle the solar collector:
- Remove the PVC wrapping to free the solar collector
from the pallet
- Tilt the solar collector slightly and grip it at the four
points shown (A) to lift it.
- Use a hoist or other suitable lifting equipment to hoist
the solar collector on to the roof.
b
Never lift the collector by its threaded water fit-
tings.
b
Wear suitable personal protective equipment and
use suitable safety devices.

Do not dispose of the packaging material into the
environment where it can become a potential haz-
ard. Dispose of the packaging material in compli-
ance with applicable legislation.
INSTALLATION
Lightning protection
The metal piping of the solar heating circuit must be con-
nected to the main potential compensation bar by a (yel-
low-green) copper wire (H07 V-U or R) of at least 16 mm
2
.
If a lightning conductor system is already installed, the
solar collectors may be connected to the existing system.
Alternatively, the solar collector piping may be connected
to ground via a ground wire sunk into the earth. Ground
wires must be sunk outside the house. The ground wire
must be connected to the potential compensation bar
through a wire of the same diameter.
Connections
Solar collectors must be connected in series using the
threaded unions provided.
If flexible pipes are not used to connect the solar col-
lectors, the piping must be fitted with expansion joints
(U-type expansion joints, flexible hoses) to absorb ther-
mal expansion. Provided adequate expansion joints
are used, up to 6 solar collectors may be connected in
series. Make sure that the unions are located correctly
when tightening them. When tightening a union with a
pipe wrench or spanner, always hold the opposite union
steady with a second tool to avoid twisting the pipe to
which the union is attached.
