2.1

INSTALLATION RECOMMENDATIONS

The total daily measured value of the incident radiation
2
is 26.7 MJ/m at an ambient temperature of 34.8 °C.
We advise not to install the appliance in climatic areas
where the radiation value is higher than the above -
quoted one.
The appliance has to be installed by professional and
qualified people who are responsible for the application
of safety regulations in force and can carry out, not only
a proper set up of the appliance, but also the necessary
tests before commissioning the plant.
During the original
maintenance, carefully follow the instructions in this
booklet.
Any change in the connections or non -observance of
these instructions will

accordance with the standard EN61024 -1 (Protection
of structures against lightning – Part 1: General
principles).
2.2 PACKAGING
The appliance is delivered packaged in a wooden box
with appropriate protection.
A pressure relief and non return valve and an envelope
containing this booklet 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 depends on the user's needs.
Useful advices:
 One appliance is
domestic hot water for two people.
 We suggest to install at least two units (the hot water
produced by the first one is quite often wasted during
the water distribution).
 If the solar system is well sized, it is possible to use
the domestic hot water produced by the appliance for
a longer period throughout the year, thus increasing
the user's savings.
If for economic reasons an undersized system is

to make a possible subsequent installation of more
appliances easier and quicker.

capacity of the appliance).

in
In all storage solar water heaters the absorbing surface
(cupola) must always be exposed to the sun.
The best positioning of the solar water heater is
SOUTHWARDS.
In order to use all the hot water stored in the tank, a 35°
installation is advised (this is valid for Italy). This angle
makes water stratification 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 during the hottest part of the day.
Suggestion for a good installation
 If possible, ALWAYS connect the hot water outlet of
the appliance to the cold water inlet of conventional
hot water systems such as gas boilers, boilers with
calorifier or fireplaces. In this way you will benefit 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
suggest to install a thermostatic water mixer and a
