GENERAL INFORMATION
In the present manual you will nd all necessary instructions with regard to the installation, operation
andmaintenance of the product.
The company is active in the Solar Energy Field with high-tech equipment, ultra-modern facilities and certied prod-
ucts of high quality. Our experience and know-how support our co operations, before and after sales, both in Europe
and internationally.
Nowadays, the necessity for production and saving of energy without at the same time polluting the environment has
become common knowledge. The planetʼs conventional energy resources are diminishing to a threatening level as
our societyʼs energy requirements are increasing, generating pollutants that affect the climateʼs balance. Renewable
energy sources promise a solution to the energy problem as well as to pollution. Gradually, the international legisla-
tion is changing and encouraging - or even imposing - the use of alternative energy products, with the aim to satisfy
energy requirements without endangering the environment.
DOMESTIC HOT WATER CONSUMPTION
Statistically, it is estimated that the mean family consumption is 35 to 50 liters daily per person. If we add the con-
sumption of a washing machine and a dishwasher, when these are connected to the solar water storage tank, then
each requires 20 liters per day (per wash). Thus, a family of four, for example, with a mean hot water consumption
of 40 liters per person, needs an 160 liters solar water heater. If household appliances connected to the solar water
heater are added, then the demand increases by at least 40 liters daily. In order to take full advantage of the solar
water heater, maximum use of hot water should be made during daytime, so that the system can continuously pro-
duce hot water during the daylight hours, maintaining thus its maximum efciency.
SOLAR WATER HEATER OPERATION - WATER HEATING
The collecting surface absorbs solar energy and heats the liquid (water or antifreeze mixture) that circulates in the
water element. This liquid when heated becomes lighter and is directed to the water storage tank where it heats the
water. The ow of the collector’s liquid is accomplished naturally and not forced (thermosiphonic ow).
The factors that affect the temperature of the water supplied by a solar system are many and their values vary accord-
ing to the season, the time of day and the location. Keeping in mind that the solar system is a system that is exposed
to the weather conditions, basic parameters affecting its performance are the mains water temperature, the available
solar energy and the ambient temperature. The mains water does not have a constant temperature throughout the
year, being much colder in winter compared to summer. Considering 45°C as a v temperature for the domestic hot
water (in order to full the needs of a home) and based on statistic values, in winter the temperature of the mains
water has to be increased by approximately 35°C, whereas during the summer the increase is 20°C.
Similarly, the available solar energy does not remain the same throughout the year, being much less in the winter
months than in the summer months. During periods of reduced sunlight and low ambient temperatures, the solar
water storage tank assures the preheating of the water and is assisted by an electrical heating element or the cen-
tral heating water storage tank (triple action solar water storage tanks). As far as night-time temperature losses are
concerned, these are limited as much as possible by the solar system’s powerful thermal insulation. They are never-
theless affected by ambient temperatures, which vary depending on the location and the weather.

RELIABILITY - HARMONY - AESTHETICS
• High aesthetics and design without obvious piping.
• All the connections between water storage tank and collector are found by the side of the system
The pipes, the cables and the connection elements are covered by special decorative ABS UV PROOF.
APOLLON Solar Systems constitute an ecological proposal and an effective energy solution, combining high
output, autonomy, aesthetics, facility in the installation and money saving. They are made of excellent materials ac-
cording to international specications and have all the certications and tests that conrm their quality.
They are highly aesthetic systems, which can be simply and quickly installed to blend with the traditional or modern
architecture of a building and to provide free hot water almost the whole year round. Even in regions with low sunlight
they achieve the preheating of the water, which contributes to a drastically reduced consumption of conventional
energy.
With the use of solar systems, thermosiphonic or forced circulation, is achieved energy saving of 70-100%. At the
same time the operation time of the boiler or electric resistance is decreased, depending on the sunlight of each re-
gion and the system’s size, with simultaneous reduction of emission of carbon dioxide.

GENERAL INSTALLATION RULES
ATTENTION! Installation must be in compliance with local & national rules concerning water and electrical instal-
lations (plumbing, electricity, hygiene, urban and others).
The solar system’s packaging must be removed at the site of installation in order to protect the device from shocks
during its transportation, making sure that the collectors are not supported on their pipe joints. Until installation is
completed, the collector’s glass must remain covered until the water storage tank is lled with domestic water, so as
to avoid the boiling of the lling liquid or the breaking of the glass. The plastic protective caps must be removed from
the water storage tank’s and the collector’s pipe joints.
Installation location - shading: Prior to installation, a proper selection of the location must be made by the install-
er (in agreement with the customer), and the surface must be checked (taking into consideration its static resist-
ance), so that it can bear the weight of the system.
On inclined roofs the system should not be placed between two beams but above a single one.
The position chosen for the solar water heater installation should not be shaded by any obstacles such as trees,
buildings and other all year round, so as to ensure at least 4 hours of uninhibited exposure of the collector to the
sun during the midday hours.
Any deviation means a reduction in the system’s performance. If a deviation from the proper orientation cannot be
avoided, then the system’s performance should be corrected by increasing the collector surface, following a study
and evaluation of the specic conditions that apply. As the sun ray’s angle of attack varies with time but also depend-
ing on the system’s location, the collector’s angle should be approximately equal to the installation location’s latitude.
At this angle the maximum energy gain on an annual basis is achieved.
Installation particularities: In case there is no compatibility between the surface where the solar water heater will be
installed (inclined or at) and the standard equipment provided with the system, a different kind of equipment should
be used. The responsibility for the equipment chosen lies on the installer and in no case on the company. It is up to
the installer to propose & install the different equipment required, who must previously agree it with the customer.
Special weather conditions: In regions suffering from heavy snowfalls, please make sure that the snow is always
timely removed. For this case and cases of regions with storms, high wind velocity, rainfall, cyclones, tornadoes, the
system must be placed on the roof as rmly as possible and must be tightened with extra metal stripes. In areas
where these conditions occur and hail of more than 20mm in diameter is to be observed, it is recommended that
insurance for the solar water heater is issued. In every case, it is recommended to secure your solar water heater on
the support base system with more metal belts than those provided.
Orientation - optimum angle: a basic factor for the system’s optimum
performance is the selection of its angle and orientation for its particular
location and the time during which the maximum gain is required.
The solar system should be positioned so that the collector’s surface
faces the geographical south, if the installation takes place in the North-
ern Hemisphere (and the geographical north for the Southern Hemi-
sphere), i.e. it should always face the Equator.

Piping: the routing of the piping and cabling must be agreed upon between the installer and the client, so as to ensure
the proper installation of the solar system in compliance with local rules concerning water and electrical installations.
Make sure that the tubes connecting the storage tank with the collector and the piping to/from the water heater are
insulated in such a way that they can withstand temperatures covering the range of: -30°C to 120°C. Anti-UV protec-
tion must be used for the insulation.
Antifreeze Liquid: The special heat transfer medium used in the closed circuit protects the system from freezing
and from salt accumulation inside the collector tubes. The jacket in which the heat transfer medium’s circulation
takes place, does not communicate with the water tank. The thermal uid must be well mixed with water in a per-
centage that is necessary to protect the system. The responsibility for the appropriate heat transfer medium quanti-
ty as well as for the use of other liquid than the one accompanying the solar water heater lies on the installer and in
no case on the company.
The use of water or inappropriate liquid may annul the warranty validity.
After the installation is completed, the area where the work was executed should be clean & tidy. The warranty
should be lled in and the customer should sign it and immediately mail it to the company. The customer should ll
in the check list provided by the company. The company does not hold any responsibility that may be the result of
an inappropriate installation or incorrect use of components used for the solar water heater installation.
INSTALLATION POSITION
The installation is only allowed on roofs and at surfaces of adequate bearing capacity. Before you proceed with the
installation, make sure that the roof and/or the construction is of adequate bearing capacity in terms of statics, always
according to the expected maximum loads at the installation point. If the installation is in a place with an extremely
big wind and snow load, the system as a whole should be statically checked by a skilled person, e.g a specialized
engineer. In special cases, strengthening or more solid constructions may be required.
Space requirements for installation on the roof (TILED ROOF)
For the installation on the roof the following points must be taken care of:
• The minimum distances from the ends of the roof should be:
- From the sides: distance equal to the width of two tiles
- From the top of the roof: distance equal to three rows of tiles
• The minimum distance limit of 0.8 m should necessarily be respected, in order for the collectors and the mounting
accessories not to be exposed to winds the power of which increases on the perimetrical edges of the roof.
Space requirements for free standing installation (FLAT ROOF)
The system should be installed at least 1.5 m away from the edges of the roof so as for:
• The systems to be accessible for maintenance reasons.
• The systems and the xing system not to be exposed to strong winds which are developed at the ends and edges
of the roof.
• The snow to be removed.
For the proper operation of the system, the minimum recommended inclination angle of the collectors is 20°

The rates listed in the above table relate to the resistance of the collector that has been tested on an inclined surface with an angle support of
15°-75° and on a at surface with an angle support of 35°. Τhe system may only be installed in locations with lower wind and snow load values
than the ones mentioned above.

GENERAL PREVENTION MEASURES
• Please respect the instructions related to accidents prevention and the safety rules during the installation of the
solar thermal systems as well as the piping.
• Please keep the work place clear and free of objects obstructing the execution of works.
• Do not let children, pets and other people to come in contact with the tools or close to the working place. This has
to be respected, especially in case of existing buildings renovation.
• Store the antifreeze liquid in a safe place away from children.
• During the execution of maintenance, service or installation modication works, please remove the electrical de-
vices and tools current collector or protect the electrical devices and electrical tools against unintended activation.
• Use only the tools intended to be used for this specic solar system. The use of other components or inappropri-
ate tools can cause accidents.
Requirements related to the personnel
• The installation of our Solar Thermal systems can only be undertaken by authorized specialized companies and
trained personnel.
• Works in electrical installations or conductors have to be executed by trained & specialized electro technicians
only.
Labour uniforms
• Have protection glasses on, as well as appropriate work uniform, protection shoes, protection helmet and special
long hair net.
• Do not wear baggy clothes or jewelry, as they me be trapped in movable parts.
• If, despite the use of protection glasses, antifreeze liquid comes in contact with your eyes, wash off your eyes with
plenty of water and with the eyes wide open.
• Please wear protection helmet during the installation works executed at the level of or above the head.
Installation of the water storage tank
• For the transportation, mounting & installation of the tank use forklifts suitable for the dimension and weight of the
tank.
• Please protect the enameling surface from beatings during transportation and installation.
• Due to the tank’s weight, there is a risk of accidents. Please make sure that the bearing capacity of the ground
where the tank is going to be installed is adequate, when the tank is full.
LIGHTNING PROTECTION
The metal construction conforms to the general requirements of the ELOT 1197 Standard and the special lightning
protection requirements of the ELOT 1412 Standard which takes into account the environmental conditions as well
as the altitude.
