Expansion Vessel - Pleion EGO Smart.Solar.Box 110 Mode D'emploi

Expansion vessel

The water held in the accumulator of the solar collector is
subjected to notable thermal excursions and, as a result,
important variations in volume.
The system is protected from the overpressure caused by
these fluctuations by the safety and one-way valve which,
if necessary, opens and allows the system to return to its
correct working pressure.
Should the user wish to prevent the safety and one-way
valve from opening, it is advisable to use an EXPANSION
VESSEL, suitably sized according to use.
When the EXPANSION VESSEL is assembled, the over-
pressure that can originate in the accumulation tank is
absorbed by vessel deformation, therefore the safety valve
does not need to intervene in normal conditions of use.
The EXPANSION VESSEL must be installed between the
safety and one-way valve and the inflow connection of the
solar collector.
The EXPANSION VESSEL must be connected using all
the methods indicated for heating systems, therefore it
must be directly connected to the accumulator (without
placing valves or taps between them) and pre-set at a
pressure of 0.5 bar less than that of the system working
pressure.

The EXPANSION VESSEL and its pre-set values must be
sized using the normal formulas that
can be found in normal hydraulic documents.
The expansion vessel must be installed by specialist
technicians and/or companies.

Starting
Use of the covering sheet
The integrated solar collector is supplied with a plasticiz-
er-free PVC covering sheet which serves the purpose of
blacking out the surface that captures the solar irradiation.
This will prevent the product from overheating from solar
exposure in the event of the collector being installed but
not connected to the water mains (therefore with no water
inside), or in any other situation where the collector volume
is wholly or partially empty.
The solar collector is not designed for exposure to direct
sunlight unless it is filled with water. If to the contrary, the
direct irradiation on the empty product will cause overheat-
ing and subsequent damage to the internal components.
In the event of using a different sun protection system,
make sure that it is plasticizer-free in order to prevent dam-
age to the transparent cover.

The cover sheet must be kept in position from
system installation to starting. Do not remove
it before having filled the collector.
Exposure to the sun when the system is empty
can damage the product; in this case the
manufacturer will not recognise any guarantee
rights.
If the solar collector should not be covered at the time of
commissioning, cover it with the supplied cover or with a
suitable blackout system and wait no less than 3 hours be-
fore starting the system loading operation.
In any case, the system must be charged with the cold sys-
tem (covered collector or early in the day).
Keep the cover sheet for future use.
DANGER!
If used again, position the sheet
carefully, making sure that the black PVC side is
turned towards the outside.

Start-up
The start-up consists of the first filling with water after installation. Fill
with water within 2 months after installation and in any case only ever
remove the covering sheet after the system has been filled and is stably
under pressure.
All the uses except start-up
If it is not possible to cover with the standard sheet supplied, always keep
the system primed with water and stably under pressure.
Filling
a) Connect the cold water supply line (from the mains or a well, etc.)
to the inlet connection as indicated in the basic hydraulic connection
diagram.
NotE: The outlet connection must be free, if a drainage tap for venting
the system has been installed upstream from the by-pass valve, this
must be opened.
b) Open the supply tap and begin to fill the accumulation tank until the
water has filled all the cylinders and the air inside has been vented
through the outlet connection.
ATTENTION! Repeat the filling and venting operations
several times, making sure that no bubbles or pockets
of air remain inside the accumulation tank. If any air
remains inside it could compromise the correct
operation of the system and even damage the collector
itself.
c) Allow the water to flow inside the system for a certain period of
time, in order to rinse out any deposits or residues that could have
entered the tank during installation. Convey the exiting water down
the drain.
In any case, it is recommended not to use the water as
"drinking" water for the first two weeks after filling and
putting the collector operation.
d) Close the drainage tap upstream from the cold water inlet and
connect the return line to the by-pass valve installed on the outlet
connection, as indicated in the basic hydraulic connection diagram.
e) Re-open the cold water drainage tap again, check the correct
installation of all the safety components and also check that there
are no leaks along the supply lines.
Make sure that all the safety components have been
installed according to the instructions in the basic
hydraulic connection diagram before opening the water
supply and putting the system into operation.
f) Lastly, turn on the hot water tap to check the correct supply of water
and eliminate any residual air in the supply line of the system.
g) After this operation, it will be possible to remove the covering sheet.
Due to the thermal inertia of the system, the
solar collector with integradìted EGO or EGO
PRIME storage will take a few sunny days to go
to full capacity. Normally the system will reach
temperatures of use after a day of full sun.
