1 GENERAL SAFETY INFORMATION
b
Check that the product is complete, undamaged
and as ordered as soon as you receive it. Report
any discrepancies or damage to the dealer 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 declara-
tion of conformity confirming that the installation has
been completed to the highest standards in com-
pliance with the instructions provided by
B
in
this instruction 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
B
.
B
declines all responsibility, contractual
or other, for damage to property or injury to persons
or animals caused by improper installation, adjust-
ment, 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 sec-
tion 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
modifies the existing structure of the roof. Verify
the suitability 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 gust-
ing 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
protection 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 cyl-
inder 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
suitable 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 no-
tify
B
’s Technical Assistance Service or a quali-
fied 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. Safe-
ty valves can therefore discharge extremely hot liq-
uids. Make sure that the expansion vessel is of a
suitable size and design for use in solar water heat-
ing systems.
b
Use proper slings to lift and move the elements of
the system. Never lift the collector or storage cylin-
der 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 follow-
ing the safety precautions specified by applicable
occupational safety standards.
a
Never install solar collectors on roofs without an ad-
equate lightning protection system.
a
Never install the system without providing proper
drainage for the two safety valves: that of the do-
mestic hot water circuit and that of the primary (so-
lar collector) circuit.
a
If the storage cylinder is equipped with a supple-
mentary heating element, never attempt any clean-
ing 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
devices without prior authorisation and instructions
from the manufacturer.
a
Never use anti-freeze other than that supplied by
B
to fill or top up the solar collector circuit. Mix-
ing different products can reduce the anti-freeze
protection 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 en-
vironment, or leave it within the reach of children,
since it can become a potential hazard. Dispose of
packaging material in compliance with applicable
legislation.
