b

As soon as you open the packaging, check
immediately that the contents are all present and
undamaged. Contact the reseller from whom you
purchased the solar collector if you notice any
problems.

b

This solar collector must be used only for the proper
purpose for which it is designed and made. The
manufacturer declines all responsibility, contractual
or other, for damage to property or injury to persons or
animals caused by improper installation, adjustment,
maintenance or use.

b

The solar collector must be serviced every two
years.

b

Work near uncovered and live electrical wires, with
which it is possible to come into contact, is only
permitted under the following conditions:

- Wires must be free from voltage for the entire
duration of the work.

- Parts remaining live must be covered or accidental
contact prevented.

- The following minimum safety distances must be
respected:

1 m for voltages of up to 1000 Volts
3 m for voltages from 1000 to 11000 Volts
4 m for voltages from 11000 to 22000 Volts
5 m for voltages from 22000 to 38000 Volts
over 5 m if the voltage is not known.
Contact with open, live electrical wires may lead to

electrocution and may even be fatal.

b

Always wear safety goggles when drilling. Always
wear safety shoes, cut-proof protective gloves and
a safety helmet when performing installation work.

b

Before beginning installation work on roofs, install
the necessary fall prevention and fall arrest devices
and ensure that all applicable safety standards are
applied.

Use only tools and materials that conform to the

safety standards that are applicable in the place of
work.

b

Only wear overalls that have a safety harness (with a
suitable safety or fall-arrest belt, ropes or slings, fall
dampers or dissipaters). In the absence of adequate
fall prevention and security devices, failure to use a
proper safety harness may lead to falls from great
heights with serious or even fatal consequences.

b

The use of ladders leaned against walls can lead
to serious falls if the ladder slips, slides of falls.
When using ladders, always ensure that they are
stable, and that suitable ladder stops are present.
If possible secure the ladder with hooks. Make
sure that there are no live electrical wires near the
ladder.

b

Especially when installing the solar collector as part
of a domestic hot water system, follow the orientation
and angle of the roof to ensure that the collector
blends in with the architecture of the building.

b

This instruction manual is an integral part of the solar
collector. It must be kept safe and must ALWAYS
accompany the solar collector, even if it is sold
to another owner or transferred to another user or
to another installation. If you damage or lose this
manual, order a replacement immediately from your
local Technical Assistance Centre.

GENERAL SAFETY INFORMATION AND PRECAUTIONS

ICV08 5

DESCRIPTION OF THE SOLAR COLLECTOR

The solar collectors are identified by two plates:

These panel type solar collectors have two water fittings
and consist of a wooden tray covered with a single­piece copper absorber plate. This has a highly selective
finish obtained by a special vacuum treatment called
"SUN-SELECT", which guarantees excellent collector
performance. The absorber plate is ultrasonically welded
to 12 copper pipes through which the heat transfer fluid
flows. The two main pipe connection manifolds are
also in copper. The top manifold has a central choke
to allow the first 6 pipes to be fed in parallel. After the
heat transfer fluid reaches the bottom manifold, it rises
through the second group of 6 pipes to the top manifold
again. This effectively doubles the thermal length of the
collector.

Each panel is protected by solar, hail-proof, tempered
glass with low iron oxide content and a high energy
transmission factor. The bottom and walls of the tray are
lined with 5.5 cm of rock wool insulation. The temperature
probe is installed in a special copper socket.
These solar collectors are easy to install recessed in the
roof. Provided they are properly installed, they provide
reliable, long lasting and extremely efficient service.

b If these plates or any other means of clearly identifying the product are defaced, removed or lost, proper installation

and servicing may be rendered difficult.

- Data plate

This lists the technical specifications and performance of the product.

- Serial number plate

This bears the collector’s code number, model and serial number.
