INSTRUCTIONS TO THE END USER AND INSTALLER
INSTRUCTIONS TO THE END USER AND INSTALLER
• The solar systems do not require the intervention of the user . It is recom-
mended though, that after the first 15 days of functioning, to check the pres-
sure of the closed circuit (collector - boiler) and that the temperatures are at
normal levels in relation with the time of the inspection, the sunlight and the
«Installation Sheet» .
• After two years of functioning, it is recommended that a program of annual
service is begun . The maintenance program is to replace the fluid loop circuit
and maintain the proportions of propylene glycol, replacing the magnesium
anode and check the operation of all existing valves
• If there is a breakage of collector’s glass, it must be replaced immediately so
that the absorber wiill not be damaged .
• In dusty conditions or small rainfall, it is recommended to clean the glass
with a damp cloth, if the collectors are dirty . It is also recommended that the
glass of the collectors are washed at least twice a year with water, except
if it often rains .
• After the installation is complete, the installer will have to inform the client
about the functioning of the system .
• In the case of any malfunction of the system, we recommend the client to
contact the installer as he knows all of the various parameters and the pos-
sible particular characteristics of the installation .
• The valves must be periodically checked to assure their correct functioning .
• The installer who will make the disassembly must be a specialized and certi-
fied installor in accordance with the national regulations that apply in your
country . When the installation is completed he must leave the place in the
same conditions as before the installation .
• The mixing valve (when installed by the installer) must not be regulated in a
temperature above 60°C . There is only one thermostat and should not be
set up above 60 °C .
• Before putting the system in operation, the installer must check all the
valves and fittings, including also the loop circuit as well as the main water
tank .
• The safety valves must be checked periodically to assure their proper func-
tioning
• If there is a danger of frost , please check the loop circuit to confirm if the
s antifreeze liquid conforms with the rules . In case of overheating check the
overheating valve to assure that the circuit is working properly .
• Do not start the system operation if the weather conditions are around 0°C .
Check the loop circuit and the quantity of the antifreeze liquid . Consult the
standards of the builder .
• The thermal efficiency and the solar quantity of the system is according to
paragraph 5 .9 of EN 12976-2, for loads defined on the proposed load .
• NOTE: during high radiation do not close the supply of water and do not
empty the system
• NOTE: The water consumption of the system can be withdrawn during high
radiations to prevent the overheating of the system .
• The heat transfer liquid is propylene glycol
• During periods of prolonged absence it is recommended the collectors to be
covered with an opaque covering so that to avoid working unnecessarily .
Do not use plastic material or glass material for their cover .
• The system does not use any electrical device for freeze protection, because
it works with propylene glycol .
• The overheating protection of this system it is not electrical dependent,
however it should not be disconnected from the electricity or water supply
network .
INSTALLATION INSTRUCTIONS
• The piping system used on the system is resistant to rain and moisture .
• The hot water piping system is thermal insulated .
• Sk maximum (snow load) is 2kN/m² according to ENV 01/03/1991, and Vm
(mean wind speed) is 180 km/h .
•
Disclaimer: This equipment can be installed in areas with snow load values
under 2kN / m² and the wind speed average under 180 km/h .
• Our equipments can be only installed with safety valve on the inlet cold water
to prevent over pressure . Αn asfety valve to is also needed in cases where
there is overheating circuit which uses metal pipes (copper, stainless steel or
steel) to hot water extraction . This pipe system is connected to the extraction
system of the equipment . This system should not cause any problems to any
other building material .
• The system should be used with mixing valve to draw-off temperature limit
of 60 °C .
• The installation of the system should be performed only by authorized install-
er . Collectors should be covered during installation . The collectors will be
filled with propylene water, without air . After that, the collectors cover
can be removed . To start using the collectors, open the water . After that, you
can use the installation . To re-check, please perform the same procedure .
• The operation of the system can start since everything was checked and is
correct .
•
The end user should also confirm that everything is correct and uses the
invoice has warranty .
• Declaration: the sizing of the system depends on the climatic conditions of
the area where the systems is installed .
• Check the gaskets, valves, fittings and thermal insulation (replacing it if nec-
essary) . Furthermore, it should check the general state of metallic structure
as well, screws and nuts, in order to detect any type of wear or damage .
This is especially important in marine environments . The charges from these
repairs will be the responsibility of the owner .
• If the water pressure exceeds 6 bar, you must install a pressure reducing
valve .
• The system should be installed as close as possible to the place of consump-
tion of hot water . It is very important to inform end user, of technical aspects
of installation, to agree with him all the details in this way, a secure installa-
tion and aesthetics possible, respecting the appearance of the building where
it will be performed .
• The system can be installed on the roof, terrace or garden, on a firm surface
and sturdy, which does not receive shade of nearby obstacles in any season .
• Comply with current regulations on water and electricity installations . Keep in
mind the local conditions of wind, especially during assembly . The damage
resulting from faulty installation are not covered under warranty .
• The tank must be full of water before filling the primary circuit or filled with
the heat transfer fluid before connecting the electrical resistance backup .
• After finished the system installation, make sure that all leftover materials
used on the installation, are collected, since they may cause injury or dam-
age to third parties .
• The reading of this instruction manual is very important, since its not
checked, may void the warranty .
• The piping system used in this system is waterproof and moisture .
• All pipes for conducting hot water are thermally isolated .
• a hose must be used for hot water draining to the nearest gutter, to avoid
damage in materials or people .
WARNING: THE INSTALLATION SHOULD NOT COMPROMISE THE
STRUCTURAL INTEGRITY OF THE BUILDING ON WHICH IS INSTALLED.
IN THE CASE OF MALFUNCTION
Ensure that:
• The climate conditions permit the functioning of the solar system .
• There is no shading of the collectors by any obstacles and that they are
clean from dust .
• That there is no leakage in the closed circuit and that all of the connections,
raccords, and pipes are tightly screwed and water-tight .
• That the function of the circulator is correctly programmed .
• The mixing valve for hot / cold water in the outlet of the boiler is correctly
adjusted and is functioning .
• The pressure of the closed circuit (indication of the manometer on the
hydraulic kit) is the same, with the one described on the «settup sheet»
(around 1 .5 – 2 .5 bar) . To start immediately the system fill the closed circuit
with a mixture or water and antifreeze liquid or adjust the automatic filling
tap, until reaching the indicated pressure in the “installation sheet” .
• There is enough liquid in the closed circuit of collectors - tank . During days
with high radiation and normal operation of the pump, the pipes in their
highest points (outlet of collectors) should be warm (be careful with the high
heating due to solar radiation) .
• The circulator is functioning if the weather conditions allow for it’s function .
By touching the circulator we can feel the vibrations of the system . Check the
electric current on the electric board and
• There is no air in the expansion vessel and the safety valve was not opened .
Note: All the connections and the installations must be done according
to the regulations (electrical, plumbing, urbanism and others) that apply
in your area. In the case of the malfunction of the system please contact
the installer.
