In the case of installation in places subject to heavy
snowfalls or on pitched roofs with slopes greater than those
indicated, it is recommended to use suitable additional
supports to safely anchor structures and system and to
implement suitable measures so that snow will not build up
behind the tank.

4.5 Installing the DHW tank
Once the support structures have been securely fastened, the DHW tank
can be positioned. It is advisable to install the heat pipe housing wells
before fitting the DHW tank on the supporting and mounting structure.
Install the copper wells where the heat pipe condensers will be housed on
the 1/2" sleeves positioned on the plating, interposing a sealant suitable
for contact with drinking water and able to withstand high temperatures.
Position the tank on the saddles, making sure that the holes of the
threaded inserts match the slots.
Take care to face the Heat Pipe housing wells towards the front part of
the system.
Then, use the hexagonal head screws to secure the tank to the structure,
placing washers between the screws and the supporting and mounting
structure.
Connect the 4 fixing points of the tank to the structure.
The handling of equipment whose weight exceeds 30 kg requires the use
of suitable means of lifting and carrying. To this end, the containers must
only be handled when empty.
Verify the presence of the magnesium anode at the installation location,
as well as its proper installation.
The DHW tanks must be installed and used in accordance with the
current national legislation in the country of use.
We recommend filling the DHW tank in order to check for any leaks or
water leakage from the Heat Pipe housing wells. In this way, once the
capturing tubes are installed, they will not run "dry".
To connect the system to the DHW circuit, refer to the hydraulic diagram below:

When the supporting structure has been assembled and securely
fastened, the DHW tank has been positioned, secured and filled, it is
possible to install the capturing tubes and parabolic reflectors.
4.6 Filling and starting the DHW tank
Do not leave the empty solar system exposed to sunlight, it
could be damaged beyond repair! In case of installation without
backfill, it is recommended not to install the capturing tubes
In order to activate the system, begin by filling the domestic
hot water circuit by simply opening the valve for the tank and
opening a utility tap for purging.
Favignana systems do not require heat transfer fluid for
their operation, as they are able to directly heat the water
contained in the DHW tank.
Do not use the DHW tank's connections or threads as
anchor points for lifting operations. If necessary, use two
slings of an adequate length as shown in the figure.
4.7 Installing capturing tubes and parabolic reflectors
Use cut-resistant gloves and protective goggles
during all handling and assembly steps of
capturing tubes.
The breakage of one of them could lead to
serious accidents.
Caution!
Capturing tubes are by their nature particularly fragile
Extreme care must be taken not to subject them to impacts
or mechanical actions that could cause damage.
Caution!
During assembly, avoid touching the heat pipe condenser
with your bare hands, as it can reach very high temperatures.
We recommend to carry out the installation of capturing
tubes early in the morning or late in the afternoon.
