PRODUCT INFORMATION
Solar collector NANOSOL 135
Technical descripon
Carefully read the safety instrucons before commencing the installaon. It’s for your own safety.
Please follow the structural instrucons if the installaon locaon of the solar system is above 600m sea level or possibly
exposed to large amounts of snow (higher than zone 4). The installaon needs to be carried out on a roof that is capable of be
aring that load. The stac bearing capacity needs to be checked on site before the installaon.
The collectors can either be transported vercally or horizontally. Aenon: Breakage of glass. Store the collectors in a dry and
shadowy place. The protecons of the manifolds have to be removed before the solar collectors are exposed to the sun and
heat themselves.
Working on the roof
Appropriate safety measures have to be arranged. Familiarize yourself with the general regulaons of accident prevenon for
construcon work of your professional associaon or let yourself be instructed by an appropriate person.The following aspects
have to be respected to achieve a secure installaon of the solar system:
• always use fall protecon while working on a roof
• respect safety regulaons when using a ladder
• while working on roof coverings with corrugated sheets the risk of breaking through exists
• secure workplaces on steep roofs
• safety clearances have to be met if an aerial pipeline leads across the roof
up to 1.000 V >1m, more than 1.000 V to 11.000 V >3m, with unknown voltage >5m.
• always wear safety goggles and gloves while working with an angle grinder
• Flat plate collectors can achieve a staonary temperature of over 200°C due to incident light. The risk of burns exists
at the connecons of flow and return. Always cover the collectors on sunny days during the installaon
• Even regular daylight might cause the fluid in the collector to vaporize. This vapor leaks from the collector connecons.
Possible risk of scalding
Aenon: glass
• Don’t extent mechanical pressure on the glass covering. Glass splinters might evoke cuts
• Wear safety goggles and gloves while installing the solar system to avoid injuries due to possible damages
Connecon
• According to DIN, a safety valve must be installed in the cold water inlet. This must not be lockable.
• According to the state of the art, a water filter must be installed in the cold water inlet.
• The domesc hot water temperature in the pipe network has to be taken to a maximum of 60 °C for normal operaon
by taking suitable measures to limit (use of suitable anscalding devices at the drawoffpoints).
With exisng lightning protecon system: minimum distance from this device: 1 meter

GENERAL INFORMATIONS
1.1 Use of the appliance
This appliance provides users with domesc hot
water, exploing solar energy and it can be used in
dependently or as a backup to convenonal hot
water system. It is:
•Ecological: Because it is polluon free and environ
mentally safe.
• Easy to be installed: Thanks to its frame it can be
located in any place. Furthermore, it needs neit
her electrical supply nor electrical components
such as: storage baeries, pumps and control
boxes.
• Cheap and economical: In installaon and main
tenance.
Panel has a square shape. Its small size in comparison
with its large storage capacity, the fact that it does
not need any electromechanical devices and its frame
make the installaon easier nearly anywhere.
This appliance is manufactured using high quality we
atherresistant materials that have been selected on
the one hand to increase solar energy absorpon, on
the other hand to make the working life of the appli
ance longer, thus reducing maintenance costs.
On demand it can even be equipped with a heater
element.
ATTENTION:
A magnesium anode, that is placed
inside the tank, protects the whole
appliance against galvanic corrosion. It has to be
replaced every 812 months.
A pressure relief and non return valve protects
the tank against excessive pressure due to the vo
lume increase of water while heang; moreover
it prevents domesc hot water from flowing back
into the cold water circuit. The lack of a suitable
pressure relief valve causes the warranty on the
storage tank to be invalided.
1.2 Descripon of components
The appliance is a storage solar water heater made
up of 4 parts:
•In the upper part there are 2 methacrylate cupo
las, a special material that increases the green
house effect, having a transparency coefficient
higher than crystal.
•In the lower part there is 1 ABS treated tray ex
ternally coated with a film of methacrylate; it is
internally insulated with expanded polyurethane
with closed cells to avoid heat losses.
•The storage tank is in steel internally coated with
enamel (2 injecon of enamel). Its external sur
face is coated with a black highly selecve paint.
Its special shape and structure make the tank
highly resistant to pressure, avoiding any possible
breakage due to frost
•The external frame is in hot dipped galvanised
steel. It can be posioned easily, according to the
user’s needs and adjusted with different angles.
Its easy way of operang and the fact that it does not
need any maintenance intervenons are the main pe
culiaries of Panel.
Enamelling is the best treatment that can be done
on steel tanks that, because of their use, come in con
tact with sanitary hot water. First of all it protects
from the natural galvanic corrosion that inevitably de
velops inside the tank; furthermore it limits the ad
herence and the prolificaon of bacterium

1.3 Safety devices
Pressure relief and non return valve
The protecon from overpressure or overheang
foresees the expulsion of a given mass of water in
case the pressure inside the tank exceeds 6 bar in
order to bring the pressure back to opmum values.
At the same me a given mass of cold water will get
into the tank lowering the temperature of water.
Warning labels
Some labels stuck on the appliance highlight some
important warnings.
Each dangerous point is marked with a suitable label.
Keep the labels clean and legible; replace those that
are missing or damaged.
ATTENTION:
Danger of serious burns! If the
appliance is located in a place easily
accessible to people, do not approach it during
the day because there could be a high tempera
ture. Keep children away from the water heater,
fencing the appliance if necessary.
ATTENTION:
If the appliance is installed in Italy,
the pressure relief valve supplied
with the appliance must be replaced with a safety
group in accordance with the UNI rule EN
1487:2002 (as required by The Memorandum N°
9571 dated 26/03/03 issued by Ministry of Pro
ducve Assets G.U. N° 87 of 14/04/03). In case
of noninstallaon of a safety group in compli
ance with the rule EN 1487, the manufacturer will
be exempted from any warranty claim on the
tank.
ATTENTION:
If the discharged hot water due to
overpressure may damage nearby
objects, we suggest to foresee a suitable draining
system in order to avoid any problem. The water
inside the tank can reach very high temperatures
(over 60 °C): for this reason in order to avoid any
risk of burning it is necessary to install a water
mixer expecially when we foresee to use the hot
water taking it directly from the panel.

PRODUCT INFORMATION Satellite collector NANOSOL 135
2.1 Installaon recommendaons
The total daily measured value of the incident radia
on is 26.7 MJ/m2at an ambient temperature of
34.8 °C. We advise not to install the appliance in cli
mac areas where the radiaon value is higher than
the abovequoted one.
The appliance has to be installed by professional and
qualified people who are responsible for the applica
on of safety regulaons in force and can carry out,
not only a proper set up of the appliance, but also the
necessary tests before commissioning the plant.
2.2 Packaging
The appliance is delivered packaged in a wooden box
with appropriate protecon. A pressure relief and
non return valve and an envelope containing this boo
klet are delivered with the appliance.
2.3 Sizing
Before installing the appliance, knowing exactly how
it will be used is very important in order to avoid an
under sizing of the whole plant. The right sizing de
pends on the user’s needs.
Useful advices:
•One appliance is suitable to produce enough do
mesc hot water for two people.
•We suggest to install at least two units (the hot
water produced by the first one is quite oen wa
sted during the water distribuon).
•If the solar system is well sized, it is possible to
use the domesc hot water produced by the ap
pliance for a longer period throughout the year,
thus increasing the user’s savings
•If for economic reasons an undersized system is
carried out, foresee brackets for other units, in
order to make a possible subsequent installaon
of more appliances easier and quicker.
•Domesc hot water consumpon: On average
about 910 litres of water flow offa tap every mi
nute (every 10 minutes = 100 litres of water. This
equals to 3/4 of the overall storage capacity of
the appliance).
2.4 Installaon and locaon
of the appliance
The water heater is delivered in a packaging. It is sup
plied with the installaon manual and with a pressure
relief valve (to be replaced with a pressure relief and
nonreturn valve in accordance with the rule EN 1487
in case the panel is installed in Italy). Once the appli
ance is out of the packaging, place it exactly where it
has to be installed paying aenon while handling it:
use the special handles in order to avoid to compro
mise the ghtness of the black seal that fixes the cu
polas to the tray. At this stage, connect the cold and
hot tubes, placing the pressure relief valve on the cold
water inlet. Then fill the tank. In all storage solar
water heaters the absorbing surface (cupola) must al
ways be exposed to the sun. The best posioning of
the solar water heater is SOUTHWARDS.
In order to use all the hot water stored in the tank, a
35° installaon is advised. This angle makes water
straficaon easier: in this way, beeing the hot water
outlet in the upper part of the tank, it is possible to
use nearly all the hot water. Moreover, thanks to this
angle, sun rays are perpendicular to the appliance du
ring the hoest part of the day.
Suggeson for a good installaon:
•If possible, always connect the hot water outlet of
the appliance to the cold water inlet of conveno
nal hot water systems such as gas boilers, boilers
with calorifier or fireplaces. In this way you will be
nefit at best from solar energy: the solar water
heater will act as an efficient heat integrator.
•In order to avoid useless heat losses, we advise to
locate the solar water heater close to point where
users withdraw hot water.
•If the appliance is located in public places, we sug
gest to install a thermostac water mixer and a
token dispenser to keep down the hot water con
sumpon.

Excellent inclinaon
Inclinaon and load resistance
The holes of the solar water heater frame allow three
different inclinaons according to needs:
•AA: 13° inclinaon in comparison with the hori
zontal line
•BB: 26° inclinaon in comparison with the hori
zontal line
•CC: 35° inclinaon in comparison with the hori
zontal line
Maximum bearable load:
•Snow (Sk): 100 kg/m2
•Wind (Vm): 110 km/h
The panel has to be installed only in those areas
where Skand Vmhave values lower than the above
stated ones.
The entry of the pipes into the building has to be
resistant against rain and condensaon: make sure
that the pipes coming out from the building and that
will have to be connected to the “cold water inlethot
water outlet” of the panel, are realized in such a way
to be resistant against rain and condensaon, in order
to avoid annoying infiltraons that would damage the
walls of the building.
Filling up
Once you connect the pipelines of the building to the
“cold water inlethot water outlet” of the panel, ma
king sure that either the pressure relief valve that is
supplied with the appliance (in case the unit is instal
led abroad) or a hydraulic safety group conforming to
the rule EN 1487:2002 proceed to fill up the tank by
simply opening the faucet placed along the cold
water supply duct.
Starng
Appliance is a simple storage panel needing neither
pumps, nor control boxes. Therefore it needs no igni
on.
Informaon about the commissioning of the plant
Once the appliance is installed, it will be enough to
fill up the tank and to wait that the sunrays, engraving
on the cupolas, warm the water stored inside the
tank.
Since the water may reach very high temperatures
(7075 °C), in order to avoid any danger of burning, it
is necessary to foresee the installaon of a water
mixer, parcularly in the case the hot water outlet is
not directly connected to points having their own
water mixer.
In a sunny summer day, Appliance can give more than
200 litres of sanitary hot water at a temperature of
about 40 °C with repeated collecng. Therefore it can
sasfy the demands of 2 people.
On the other hand, in the winter season it can be
used as preheater, connecng it in series to an al
ready exisng water heater or heang boiler.

Examples of possible posioning:
Installaon on a vercal wall:
In order to make the kind of installaon shown effi
cient, it is necessary to invert the cold water inlet and
the hot water outlet.
The pressure relief and nonreturn valve has always
to be fied on the cold water inlet).
2.5 Connecon and pipework
Pipes insulaon
We suggest to insulate the cold water pipe to the
water heater and the hot water pipe from the water
heater, because they could freeze during the winter
me.
The insulaon of the tubes can be obtained by using
some covering in expanded elastomer.
Pipe secon
The advisable pipe secon is 1/2”. However, if the ap
pliance is a long way from the point where hot water
is used, a 3/4” pipe secon is suggested.

Fing of the pressure relief and non return valve
The pressure relief and non return valve supplied with
the appliance must be fied to the cold water inlet (the
arrow on the valve must be poinng towards the tank),
without any intercepon between the valve and the
water heater (1).
This valve has a double funcon:
•safety funcon: it allows the discharge of the
water stored inside the tank in case the pressure
exceeds the limit fixed by the valve seng.
•nonreturn funcon: it avoids that, because of
the high pressure that may arise inside the tank,
the hot water flows back along the cold water
tube.
Fing of the drain valve
The fing of a drain valve (2) is recommended to
empty the tank: it has to be installed between the
safety valve and the appliance.
ATTENTION:
If the appliance is installed in Italy,
the pressure relief valve supplied
with the appliance must be replaced with a safety
group in accordance with the UNI rule EN
1487:2002 (as required by The Memorandum N°
9571 dated 26/03/03 issued by Ministry of Pro
ducve Assets G.U. N° 87 of 14/04/03). In case
of noninstallaon of a safety group in compli
ance with the rule EN 1487, the manufacturer will
be exempted from any warranty claim on the
tank.
2.6 Installaon o the appliance
Installaon of a single unit
If just one appliance is installed, it has to be connected
to the water system directly.
Installaon of several appliances in a row
If several units are to be installed, the appliances have
to be connected as shown in the diagram. Foresee
just one pressure relief and non return valve that
has to be fied to the cold water inlet of the first ap
pliance.
Frame
To give the water heater the right angle, use support
brackets and screws included in the frame. Once you
have determined the right angle of installaon, you
have to match the hole in the bracket with the hole
in the frame (1): then insert the bolt and ghten the
nut (2). To give the appliance an angle different from
the ones foreseen by the manufacturer, drill the
frame in order to obtain the desired angle.
2.7 Magnesium Anode
To extend the working life of the appliance, respect
the following parameters, as foreseen by the Euro
pean Direcve 98/83/CE (regarding the quality of
water intended for human use):
• overall water hardness: included between 15
and 50 °F (in parcolar where water has under
gone a soening or desalisaon treatment)
• chloride:s 25 mg/l (max. value 200 mg/l)
• pH: included between 6,5 and 9,5
• conducibility: 400 μS/cm (max. value 2500 μS/cm)
10 © Solarbayer GmbH (213859)
PRODUCT INFORMATION Satellite collector NANOSOL 135
Where water does not suite the above parameters,
the warranty will decay automacally.
The solar water heater is equipped with a magnesium
anode (1) that protects the tank against galvanic cor
rosion.
It has to be replaced every 812 months.
To replace the anode:
• close the water supply
• reduce pressure in the water system opening a
hot water tap
• remove the anode protecon
• unscrew the anode holder
• remove the old anode and replace it with the new
one
• screw the plug being sure that the ghtness is
granted
• close the hot water tap
2.8 Possible operaon defects
If the hot water producon of the appliance is not
enough, there can be several reasons:
Improper installaon of the panel
• remember that this device must be installed with
orientaon to the SOUTH and inclinaon of 35°
to the horizontal and in areas where we do not
create shade during the day.
Incorrect panel
• a connuous sampling of hot water by different
users does not allow water inside the tank to heat
up. Being a panel storage, water should be stan
ding in the tank unl it is warmed
Undersizing system than the real situaon
• if a single device is required to reach more users
(bathrooms and kitchens) on different floors of a
building with long pipes, the plant is undersized;
you need to add one or more panels or to make a
series connecon with a possible water heater or
boiler.
Hole in the tank
• This incident, due to the non replacement of the
magnesium anode, causes the tray to be filled up
by water. As a consequence the insulaon in ex
panded polyurethane becomes soaked with water
and the whole appliance has to be replaced
Breaking of one cupola (of of both)
• The breaking of one or both cupolas, with the
consequent making of consensaon between
them, lowers the efficiency of the appliance. The
cupolas will have to be replaced.
Making of condensaon between the cupolas
• If the making of condensaon between the cupo
las is not due to their breaking but to the release
of the black gasket that fixes the cupolas to the
tray or to the wear of the silicone used to grant
the ghtness, it is necessary to remove the cupo
las, dry them fully and reassemble them using a
non acec silicone to seal in order to avoid any
chemical reacon that may damage the cupolas.
2.9 How to use the appliance
• Never empty the tank to avoid any risk of brea
king of the inner cupola and the subsequent con
dense formaon, that prevents the sun from
warming water.
• In case the tank has be emped and the appliance
is lewithout water, protect it with Opaque ma
terials.
• Empty the tank only if the outer temperature
falls below 20 °C, in order to avoid possible da
mage caused by ice.
• If there is a STOP COCK on input COLD WATER,
this should never be closed.
• If the appliance remains exposed to the sun for
long me without using water and it is not instal
led a water mixer aer the appliance itself, it is
necessary to be careful about the danger of
burns due to the high temperature of the water.
2.10 Maintenance intervenons
Cleaning of the solar water heater
In storage solar water heaters the transparent outer
cupola has to be as clean as possible, because dust
and dirness prevent sun rays from warming water at
best. As a result, the solar water heater efficiency
would be reduced considerably.
To clean the cupola use a wet and socloth: when
scratched the cupola lost its transparency.

Instrucons for lightning protecon
The general principles for protecon against lightning are stated in DIN EN
62305 part 3 / VDE 01853053 (protecon against lightning, physical
damage to structures and life hazard) and in supplementary sheet 2
(Photovoltaic and solar thermal systems).
If a lightning protecon system is installed on a structure as external
lightning protecon the collectors and its installaon rails have to be
connected to the protecon system. A specialist for lightning protecon
has to check if either the solar system is within the range of a lightning
protecon system or what arrangements have to be met. Aenon: It is
not
allowed to draw a conducve connecon between the collector and the
exisng lightning protecon system (danger of launching the lightning into
the house!) A safety clearance of approx. 0,5 m from the collector array to
the conducve parts of the lightning protecon system has to be
maintained to all sides. The exact calculaon of the safety clearance is
stated in DIN EN 62305 part 3. If it is impossible to keep up the safety
clearance a specialist for lightning protecon has to realize the necessary
regulaons.
Furthermore it has to be considered: If the lightning protecon is outdated
and no longer in accordance with the norm, the right of connuance expi
res due to the mounng of the collectors. In this case the lightning protec
on system has to be revised.
Source: informaon sheet no. 34, march 2009, Operang Reliability of
Solar Thermal Systems. For further informaon see: www.BDHKoeln.de
Overload protecon: In order to protect the collector sensor and the
control unit against overload you can install an overload arrester. Nearby
lightning might induce voltage peaks which can destroy the sensor or the
control unit. Protecve diodes limit the damage caused by overload to a
minimum. Solarbayer control units are regularly equipped with an overload
protecon.
Potenal equalizaon: The solar system is to be connected to the
structure’s exisng potenal equalizaon by a specialist.
When planning and mounng, it is always the most recent version of this guidlines and regulaons that has to be paid aenon to!
