This manual provides all the necessary instructions for installing, operating and servicing the natural circulation sys-
tem SIME NATURAL 160S - 200S - 300/5.2S - 320S.
Nowadays we know that we need to produce and save energy without polluting the environment. Our planet's conven-
tional energy resources have decreased to an alarming level while people's energy requirements increase, generating
polluting agents that affect the climatic balance.
The renewable energy sources solve the energy and pollution problems. The international legislation is gradually modify-
ing and encouraging, even imposing, the use of alternative energy products with the aim of meeting the energy require-
ment without placing the environment at risk.
D.H.W. REQUIREMENT
It was statistically calculated that the average daily consumption of a family varies from 35-50 litres per person. Should
we add the consumption of the washing machine and dishwasher in case they were connected to the solar system, around
20 litres are required daily for each appliance (for one wash).
A family made up of four people with an average D.H.W. consumption of 40 litres per person, requires a 160 litre solar
water heater. The requirement increases by at least 40 litres per day if we add the domestic appliances connected to the
solar system. To obtain the maximum benefit from the solar water heater, use the highest amount of hot water possible
during the day so that the plant can continuously produce during the sunny period, maintaining yield to a maximum.
SOLAR SYSTEM FUNCTIONING - WATER HEATING
The collector surface heats the liquid (water or anti-freeze solution) circulating in the solar collector, through the so-
lar energy it absorbs. The heated liquid becomes less heavy and moves towards the boiler heating the water contained
therein. The collectors' liquid circulates naturally (thermosyphon flow).
There are many factors affecting the temperature of the water supplied by a solar panel and their oscillation values vary
depending on the season, time of day and place.
As the solar panel is a system exposed to atmospheric conditions, the essential parameters affecting its yield are the
supply water temperature, the solar energy available and the environment temperature.
The temperature of the mains water is not constant during the year as it is much colder in the winter than the summer.
Considering 45°C as satisfying D.H.W. temperature (to meet the requirements of a home), it is given from the static data
that the temperature of the mains water must increase by 35°C during the winter and 20°C in the summer.
Furthermore, the available solar energy is not constant during the year as it assumes lower values during the winter
months with respect to the summer period. The solar panel assures pre-heating and is assisted by using the electric
heater or the central heating boiler (triple energy systems), in cases of reduced sun and low environment temperature.
The heat losses during the night are minimised by the system's efficient thermal isolation. The leaks depend on the en-
vironment temperature that varies depending on the place and climatic conditions.

Certification
Solar Keymark
The natural circulation solar systems Sime Natural S constitute an ecological proposal and efficient energy solution that
combines high results, autonomy, aesthetics, easy installation and money savings. They are made with materials that
meet the international specifications. Their quality is proven by all the relative certifications and tests.
These are cutting-edge aesthetic systems that can be easily and quickly installed, they adapt to the more traditional or
modern architectural style of buildings and allow using D.H.W. almost all-year-round. Even in the regions with scarce
sunlight, the solar systems reach water pre-heat thus contributing to the significant reduction of conventional energy
consumption.
An energy saving varying between 70 and 100% is obtained by using natural circulation solar systems. At the same time,
the boiler or electric heater operating time is reduced with a simultaneous reduction of the carbon dioxide emissions,
based on the sunlight of the different regions and the system dimensions.

GENERAL INSTALLATION RULES
ATTENTION:
Installation must be conform to the local standards in force for hydraulic and electric plants.
Remove the water heater packaging in the place of installation to protect the equipment against impacts during transport,
avoiding resting the collectors' weight on the pipes connection fittings. The collectors' crystals must remain covered until in-
stallation is completed, until the boiler is filled with domestic water to avoid the filling liquid from boiling or the crystals from
breaking. Remove the plastic protective caps from the boiler and collectors' connection fittings.
Installation point: the installer must accurately choose the place of installation before proceeding, (in agreement with the cus-
tomer). It is also necessary to check (considering the static resistance) that the surface is able to support the system's weight.
On inclined roofs, the system must never the placed between two beams but above a single beam.
Direction - Perfect inclination - Shading: It is essential, in order to obtain maximum solar system yield, to properly choose the
inclination and direction with regard to the installation place and the maximum production period requested. The solar panels must
be directed so that their surface faces the geographic South in the northern hemisphere (geographic North in the southern hemi-
sphere), meaning they always face the equator.
A change of direction means a decrease in the plant's yield. Correct the system yield if the change of the correct direction is inevi-
table, by increasing the collectors' surface based on an assessment of the specific conditions.
As the angle of incidence of the solar radiation changes with the season and with the system's place of installation, the collectors'
angle of inclination must be almost equal to the place of installation latitude. This inclination gives a maximum annual energy
production. Avoid the system being shaded by trees,
buildings, other obstacles in order to guarantee the
collectors' surface to at least 4 hours of full exposure
of solar radiation during midday.
Installation specification: should the installation
surface of the solar heater (inclined or flat) not be
compatible with the standard equipment supplied
with the system, a different type of equipment must
be used.
The installer is responsible for choosing the equip-
ment. The company is in no way responsible. Prior
agreement with the customer, the installer is re-
sponsible for proposing and installing the different
equipment required.
Particular atmospheric conditions: it is necessary
to make sure that, in regions characterised by heavy
snow, this is immediately removed. In this case and in
regions affected by storms, strong wind, heavy show-
ers, cyclones and tornado, the system to be placed on
the roof must be as stable as possible and secured
with further metal straps.
We recommend stipulating an insurance policy for the solar water heater in areas where these conditions occur and hailstones
larger than 20 mm are seen. However, we recommend fixing the solar water heater to the basic support system using more metal
belts than supplied.

Piping: the piping and cables' path must be agreed between the installer and the customer to guarantee perfect solar
system installation, in compliance with the local standards on water and electric systems.
Make sure the connection pipes between the tank and the collector and the pipes from and to the water heater, are ad-
equately isolated to support temperatures between: -30ºC and 120ºC. Anti-UV protection must be used for the insulation.
Anti-freeze liquid: the special heat transfer means used in the closed circuit protect the system against freezing and
salt accumulation inside the collector's pipes. The double wall where the heat transfer mean circulates does not com-
municate with the water storage tank. The thermal fluid must be mixed with an adequate amount of water to protect the
system. The responsibility for an adequate amount of heat transfer mean and use of a different liquid from that supplied
with the solar water heater, lies with the installer and the company.
The use of water or other inappropriate liquid may cancel the warranty.
The work execution area must be cleaned and tidied-up once installation is completed. The warranty form must be filled-
in, signed by the customer and immediately sent to the company. The customer must also fill-in the check list supplied
by the company. The company does not undertake any liability deriving from an inadequate installation or incorrect use of
the components used for installing the solar water heater.
POSITIONING THE SOLAR COLLECTORS
The plant can only be installed on flat roofs and surfaces with adequate supporting capacity. Make sure the roof and/or
construction have an adequate supporting static capacity, according to the maximum loads foreseen in the installation
point, before installing.
The entire system must be checked by an expert, such as a qualified engineer, from a static point of view, should the plant
be in an extremely windy or snowy area. Reinforced or more solid constructions may be required in particular cases.
Space requirements for roof installation
Tiled roof
The following steps must be carried out for roof installation:
- The minimum distances from the roof ends must be:
- From sides: same distance to the width of two tiles.
- From the top of the roof: same distance to three rows of tiles.
- The minimum distance limit of 0.8 m must be respected to avoid exposing the collectors and assembly accessories to
wind, which force increases along the roof perimeter.
Space requirements for single installation
Flat roof

- The systems are accessible for maintenance.
- The plant and fixing system are not exposed to strong winds developing at the ends and along the edges of the roof.
- The snow is removed.
GENERAL PREVENTION MEASURES
- The solar heat systems and relative piping must be installed respecting the health and safety and accident prevention
instructions.
- Keep the work place clear and without objects that can obstruct executing the work.
- Do not allow children, animals and other people to come into contact with the instruments or near the work place.
This rule must be respected, particularly when restructuring already existing buildings.
- Preserve the anti-freeze liquid in a safe place, away from the reach of children.
- Remove the devices and electric instruments of the current collector or protect them against an accidental switch-on
during maintenance execution, assistance or change in installation.
- Only use the instruments provided for this specific solar system. The use of other inadequate components or instru-
ments can cause accidents.
Personnel requirements
- The thermal solar systems must only be installed by qualified companies and trained personnel having appropriate
authorisation.
- Work on the plants and electric wires must only be carried out by qualified and trained electricians.
Personal protective equipment
- Wear protective goggles, adequate work clothes, protective shoes and helmet and a specific net for long hair.
- Do not wear wide clothes or jewellery as they may get caught up in the moving parts.
- Should the anti-freeze liquid come into contact with the eyes, despite using the protective goggles, keep the eyes open
and rinse them with running water.
- Wear the protective helmet during installation carried out level with or above the head level.
Boiler installation
- For boiler transport, assembly and installation, use suitable forklifts for the boiler dimensions and weight.
- Protect the glazed surface against impacts that might occur during transport and installation.
- There is a risk of accidents due to the boiler weight. Make sure the capacity of the support plan where the boiler will
be installed is also adequate for a full boiler.
Dismantling the system
The thermal solar system must only be dismantled by qualified companies and trained personnel having appropriate
authorisation. Only trained and qualified electricians can disconnect the electric parts.
Exhausted thermal solar systems must be disposed of in compliance with local regulations. Where possible, particular
attention must be paid to materials recycling.
PROTECTION AGAINST LIGHTNING
The metal parts of the entire system conform with the main requirements of Standard ELOT 1197 and the special protec-
tive requirements against lightning of Standard ELOT 1412 that considers the environmental conditions and the altitude.
