observed
For both installation and maintenance, it is necessary to
leave free spaces around the storage tank, as shown in
gure 5-1.
5 - INSTALLATION
5.2 - Selection of place of
installation
WARNING! The unit must be installed only on
a horizontal surface that will take its weight, take into
account the weight in service of the storage tank (see
section 8 technical specications) plus the hot water
heater if it’s the type with a base, both full of water
(for details relating to the hot water heater see its
installation manual).
Determine the room and the right position for installation,
taking the following factors into account:
- dimensions and weight of the unit;
- connection to water supply;
- connection of domestic hot water system;
- any eventual connection of storage tank drain
(recommended);
- any eventual connection of storage tank safety valve drain
(recommended);
- any eventual connection of storage hot water heater
safety valve drain (recommended);
- connection to electric power supply of electronic anode (if
present);
- As far as the hot water heater’s connections are
concerned, see the instructions in its installation manual.
This storage tank must be installed in a place where
any leakage of water that comes from it, from the joints
between pipes or from any discharge from the safety
valve, cannot cause any damage to materials or things
below it.
5.3 - Installation of electronic
anode rode
WARNING! The presence and correct operation
of the electronic anode rode is indispensable to protect
the storage tank from corrosion.
The electronic anode rode is supplied already installed in
the storage tank.
The position of the electronic anode rode in the storage
tank is shown in section 3. Follow the instructions in the
control unit and the cables supplied with the storage tank to
make the electrical connection. To check correct operation,
follow the steps described in section 7.1.1.
5.4 - Storage tank earthing
WARNING! For correct operation of the
electronic anode rode the storage tank must be
“earthed”. If the earthing is not carried out correctly the
protection of the tank cannot be guaranteed.
5.5 - Domestic hot and cold
water
WARNING! Install a lter with a mesh not wider
than 0.5 mm2 in the domestic cold water inlet.
WARNING! Read the water heater installation
manual for the treatment of the domestic hot and cold
water.

6 - USE
6.1 - Important information
WARNING! We would remind you that the
assembly, adjustment and maintenance of the electrical
and hydraulic connections of your unit can only be
carried out by a professionally qualied engineer.
In the event of a breakdown or poor operation,
disconnect the unit and do not attempt any repair or
direct intervention. Contact a professionally qualied
engineer.
 To ensure the e󰀩ciency of the unit and its correct
operation, periodic maintenance must be carried out be a
professionally qualied engineer.
The engineer will explain the operation and use of the
unit to the user.
 The user must know how to ll and empty the system.
6.2 - Troubleshooting
In case of water leaks
Close the house’s main cold water valve;
 Call a professionally qualied engineer.
If no DHW is produced
Check the hot water/boiler is not paused.
WARNING! If after these checks the DHW is still
cold, do not try to solve the problem yourself, but call a
professionally qualied engineer.
6.3 - Operations prior to
commissioning the system
6.3.1 - Valves opening check
Any valves on the hot and cold water must be open.
6.4 - Control panel
The storage tank does not have a control panel, for any
adjustment follow the directions in the installation, use and
maintenance manual of the water heater/boiler it is used
with.
6.5 - Switch-on procedure
See the directions given in the installation, use and
maintenance manual of the water heater/boiler it is used with.
6.6 - Switch-o󰀨 procedure
If the storage tank is not to be used for a relatively short time
(a few weeks and when there is no risk of frost), just turn o󰀨
the water heater/boiler as described in its installation, use
and maintenance manual. If there is a risk of frost during the
time the storage tank is not being used, the system must be
drained, proceeding as follows:
Follow the procedure to drain the domestic hot water
circuit described in section 7.1.2;
6.7 - Anti-frost precautions
WARNING! The anti-frost protection service
o󰀨ered by the unit connected to the storage tank
cannot guarantee anti-frost protection to the storage
tank, central heating system, DHW system, or the
building served or parts of it.
If you are not using the storage tank for a long period (more
than a year), we recommend you to drain it following the
procedure described in section 7.1.2.
6.8 - Anti-Legionella
For the preparation of DHW the storage tank must be
connected to a special device thanks to which a cycle of
disinfection against the Legionella bacterium is o󰀨ered.
This cycle takes the storage tank up to a temperature of
60°C (temperature at which the Legionella bacterium dies)
after two hours of electric power supply and at least once a
week. For this reason the water (at some times) may reach
users at a higher temperature than that set with the relevant
command.
WARNING! A domestic hot water temperature
greater than 51°C can cause injury or damage, even of
a permanent nature, to people and animals and things.
In particular, children, the elderly and the disabled must
be protected against any possible risks of scalds, by
inserting devices that limit the temperature of use of
the DHW to users.
