Pressure Reducer - Pleion EGO Smart.Solar.Box 110 Mode D'emploi

Positioning and fixing the backflow
preventer
The solar collector with integrated storage is protected
from negative pressures by a backflow preventer (or air
feed valve) that is assembled on the outflow connection.
This valve comes already pre-installed but it needs to be
correctly orientated and anchored by the installer.
For the coupling, use the pair of flat ¾'' gaskets supplied
with the collector. For ensuring correct operation of the
valve and the validity of the warranty of the collector, the
aforementioned by-pass valve must never be isolated,
obstructed or covered. For the correct positioning please
refer to the installation diagram in the "HYDRAULIC
4 5 6 7 8
CONNECTION" section.

A flat ¾'' gasket is placed between the valve and the
outflow connection in the factory; the valve is only
tightened by hand.
The valve body should be
directed so that the suction
element (black plastic) is
turned perfectly upwards
(in other words, it must
create a 90° angle as to the
horizontal surface.

Before tightening the valve to the outflow connection,
connect between the valve and the user supply line.
To do this, keep the plastic connection still using a no. 36
spanner and lock the valve body by tightening the pipe
connection. A maximum tightening force of 20 Nm can be
applied to the plastic connections and the valve body (it is
best to use a torque wrench to avoid exceeding this value).
A valve that is not positioned correctly can easily
become clogged or dirty, which results in loss of
functionality and leaks. No guarantee rights will be
recognised if the previously mentioned valve is not
installed or is installed incorrectly.

Pressure reducer

It is obligatory to install a PRESSURE REDUCER calibrated
to 3 Bar; for the correct positioning please refer to the
installation diagram in the "HYDRAULIC CONNECTION"
section.
The pressure reducer is available as an accessory (see the
"ACCESSORIES ON REQUEST" section)
In case of failure to carry out the proper
installation or maintenance, or if the calibration of
the pressure reducer is incorrect, the producer will
not acknowledge any warranty rights.

Thermostatic mixer valve
In order to limit/adjust the operating temperature and
avoid any burns from the hot water produced, it is nec-
essary to install the THERMOSTATIC MIXING VALVE,
available as an accessory on request (code 4400224500).
This solution "protects the user from scalding hot water
flowing out after a period during which the water was not
used", as indicated in section 5.2 of Standard EN 12976.
DANGER OF OVERTEMPERATURE
To prevent risks of burns and scalding, always
install a thermostatic mixer valve.
Connecting more than one collector mod. 110/180/260
If it is necessary to use several collectors, parallel connection is strongly recommended.
The parallel connection must be made in a balanced manner, as shown in the
hydraulic diagram and follow.

Connecting more than one collector mod. 150/220
The components surrounded by a broken line, identified
by this icon, make up a basic set that is always present
i
in all possible system configurations. For simplicity, these
components are not shown in other hydraulic drawings, but
their presence is indicated by the relative icon.

Do not serial connect two or more solar collectors with integrated
storage. The system was not designed and produced for these
applications. Serial connecting the solar collector collectors can cause
faults or even damage the product, therefore the manufacturer will not
recognise any guarantee rights.
Install the THERMOSTATIC MIXER valve along the water
inflow line connected to the
solar collector, downstream
of the backflow preventer.
Connect a branch of the
"cold" water line to the
lower part.
The domestic water
temperature must be set
as required within the
range of 35-55 °C. Use the
adjustment knob to do this.
