2 - INSTRUCTIONS TO THE INSTALLER
Inclination and load resistance
The holes of the solar water heater frame allow three
different inclinations according to needs:
 A-A: 13° inclination in comparison with the horizontal
line
 B-B: 26° inclination in comparison with the horizontal
line
 C-C: 35° inclination in comparison with the horiz ontal
line
Maximum bearable load:
2
 Snow (S ): 100 Kg/m
k
 Wind (V ): 110 Km/h
m
The panel has to be installed only in those areas where
S and V have values lower than the above-stated
k m
ones.
The entry of the pipes into the building has to be
resistant against rain and condensation: make sure
that the pipes coming out from the building and that will
have to be connected to the "cold water inlet - hot water
outlet" of the panel, are realized in such a way to be
resistant against rain and condensation, in order to
avoid annoying infiltrations that would damage the walls
of the building.
Information about the revision, filling up and starting
up of the plant
Revision
The appliance must be revised at least once a year. In
particular it is necessary to verify:

The state of the cupolas and the tightness of the
seal: make sure that there are neither cracks in the
cupolas, nor cracks in the tightening gasket in order
to avoid the formation of condensatio n between the
cupolas that would lower the output of the panel.

The state of the tray: make sure that there is no
water leakage from the appliance because this would
mean that there is a hole somewhere in the tank:
• either because of missed annual replaceme nt of
the anode, in presence of water parameters in
accordance with what foreseen by the D. Lgs
02/02/2001, n° 1 (see page 15)
• or because annual replacement of the anode, but
in presence of water parameters that do not
comply with what
02/02/2001, n° 1 (see page 15)
Filling up
Once you connect the pipelines of the building to the
"cold water inlet - hot water outlet" of the panel, making
sure that either the pressure relief valve that is supplied
with the appliance (in case the unit is installed abroad)
or a hydraulic safety group conforming to the rule EN
1487:2002 (in case the unit is installed in Italy), proceed
to fill up the tank by simply opening the faucet placed
along the cold water supply duct.
Starting
Appliance is a simple storage panel needing neither
pumps, nor control boxes. Therefore it needs no ignition.

foreseen by the D.
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 (70 -
75 °C), in order to avoid any danger of burning, it is
necessary to foresee the installation of a water mixer,
particularly in the case the hot water outle t 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 collecting. Therefore it can satisfy
the demands of 2 people.
On the other hand, in the winter season it can be used
as pre-heater, connecting it in series to an already
existing water heater or heating boiler.
