1 GENERAL SAFETY INFORMATION
b Check that the product is complete, undamaged and
as ordered as soon as you receive it. Report any dis-
crepancies or damage to the Sdealer who sold it.
b This product must be installed by a legally qualified
heating engineer. On completion of the installation,
the installer must issue the owner with a declaration
of conformity confirming that the installation has been
completed to the highest standards in compliance
with the instructions provided by Sin this instruc-
tion manual, and that it conforms to all applicable
laws and standards.
b This product must only be used for the purpose
for which it is designed and made, as specified by
S. Sdeclines all responsibility, contractual or
other, for damage to property or injury to persons or
animals caused by improper installation, adjustment,
maintenance or use.
b Make sure that the roof is strong enough to support
the weight of the solar water heating system under
operating conditions. Also make sure that the section
of roof chosen for the installation enjoys a high level
of insolation, and is not shaded during the day by tall
plants, trees, other houses, hills, etc..
b The installation of a solar water heating system mod-
ifies the existing structure of the roof. Verify the suita-
bility of all roof elements and if necessary adapt them
to avoid leaks or damage by wind and/or snow loads.
b If the system is installed in an area subject to gusting
winds or snow loads in excess of the limits given in
the technical specifications, consult your supplier for
advice.
b Snow can build up in the sheltered area behind the
solar water heating system. Provide adequate protec-
tion to avoid increasing the static load on the roof.
b The system must be serviced at least once a year.
b The water supply circuit must permit the storage
cylinder to be filled and emptied in safety. Shut-off
valves must therefore be easily accessible to the user
and the operation of emptying the storage cylinder
must not create any risk of flooding or other damage.
b Insulate the domestic water pipes (hot and cold) and
the pipes of the solar collector circuit. Provide suita-
ble insulation for all outdoor accessories.
b The point through which the water pipes enter the
building must be rain-proof and damp-proof.
b If you notice any water or heat transfer liquid leaks,
disconnect the system immediately from the mains
electricity supply (if a supplementary heating ele-
ment is installed), shut off the water supply, and notify
S’s Technical Assistance Service or a qualified
heating engineer immediately.
b Make sure that the water-glycol mix in the solar col-
lector circuit is able to resist the minimum tempera-
tures likely to occur in the place of installation.
b The system can reach very high temperatures. Safety
valves can therefore discharge extremely hot liquids.
Make sure that the expansion vessel is of a suitable
size and design for use in solar water heating sys-
tems.
b Use proper slings to lift and move the elements of the
system. Never lift the collector or storage cylinder by
their fittings. Avoid subjecting the collector to impacts
or mechanical strain, and take care to protect the
glass panel. Use the personal protection equipment
required by applicable safety standards.
2 PRECAUTIONS
a Never attempt to install the system without using the
personal protection equipment and without following
the safety precautions specified by applicable occu-
pational safety standards.
a Never install solar collectors on roofs without an ade-
quate lightning protection system.
a Never install the system without providing proper
drainage for the two safety valves: that of the domes-
tic hot water circuit and that of the primary (solar col-
lector) circuit.
a If the storage cylinder is equipped with a supplemen-
tary heating element, never attempt any cleaning or
maintenance without first disconnecting it from the
mains power supply.
a Do not allow children or infirm persons to operate the
system unsupervised.
a Do not tamper with or adjust the safety or control de-
vices without prior authorisation and instructions from
the manufacturer.
a Never use anti-freeze other than that supplied by
Sto fill or top up the solar collector circuit. Mixing
different products can reduce the anti-freeze protec-
tion provided.
a Never drain the solar collector circuit under sunny
conditions or when the collector is hot.
a Do not dispose of packaging material into the envi-
ronment, or leave it within the reach of children, since
it can become a potential hazard. Dispose of packag-
ing material in compliance with applicable legislation.
