e instruction book is an integral and essential part of the product and must be consigned to the new user also in the case of transfer or succession of ownership.
It must be stored with care and consulted carefully, as all of the warnings provide important safety indications for installation, use and maintenance stages.
is instructions manual provides technical information regarding installation of Immergas storage tank units. As for the other issues related to installation
of the said storage tank units (e.g. safety in the work site, environment protection, injury prevention), it is necessary to comply with the provisions specied in
the regulations in force and principles of good practice.
In compliance with legislation in force, the systems must be designed by qualied professionals, within the dimensional limits established by the Law. Installation and maintenance must be performed in compliance with the regulations in force, according to the manufacturer’s instructions and by an authorised
company, which has specic technical expertise in the system sector, as required by Law.
Improper installation or assembly of the Immergas appliance and/or components, accessories, kit and devices can cause unexpected problems to people, animals
and objects. Read the instructions provided with the product carefully to ensure a proper installation.

INSTALLATION
1.1 INSTALLATION RECOMMENDATIONS.
Only professionally enabled companies are authorised to install Immergas appliances.
Installation must be carried out according to the
Standards, current legislation and in compliance
with local technical regulations and the required
technical procedures.
Before installing the appliance, ensure that it is
delivered in perfect condition; if in doubt, contact
the supplier immediately. Packing materials
(staples, nails, plastic bags, polystyrene foam,
etc.) constitute a hazard and must be kept out of
the reach of children.
1.2 MAIN DIMENSIONS.
1-1
80 litre stainless steel storage tank unit
If the appliance is installed inside or between
cabinets, ensure sufficient space for normal
servicing; therefore it is advisable to leave a gap
of 2÷3 cm between the storage tank casing and
the sides of the cabinet.
In the event of a malfunction, fault or incorrect
-operation, disable the storage tank unit and
contact an authorised company (e.g. the
Authorised Technical Assistance centre, which
has specically trained sta and original spare
parts). Do not attempt to modify or repair the
appliance alone.
Failure to comply with the above implies personal
liability and invalidates the warranty.
• Installation Standards: These storage tanks
have been designed for oor installation; they
must be used for the storage of domestic hot
water and similar purposes. ey have not be
designed for wall-installation.
Important: these units are used to store water at
a temperature below boiling point at atmospheric
pressure. ey must be connected to a boiler and
to a DHW water distribution network. ey must
be installed in rooms where the temperature
cannot fall below 0°C and must not be exposed
to atmospheric agents.

washed thoroughly to remove any residues that
could compromise the good functioning of the
storage tank. Water connections must be made in
a rational way using the couplings on the storage
tank template. e storage tank safety valve outlet
must be connected to a draining funnel. If this

1.4 SYSTEM FILLING.
Once the storage tank has been connected, ll
the system via the boiler lling valve. Filling is
performed at low speed to ensure release of air
bubbles in the water via the boiler and central
heating system vents.
Close the lling valve when the boiler manometer
pointer indicates approx. 1.2 bar (see boiler
instruction book).
1.5 DOMESTIC HOT WATER STORAGE TANK UNIT.
e storage tank unit must be connected to a
boiler. It contains large coiled stainless steel heat
exchanger pipes, which allow to notably reduce
hot water production times. is storage tank
unit, manufactured with stainless steel casing and
MAINTENANCE TECHNICIAN
bottoms, guarantees long duration through time.
e assembly concepts and welding (T.I.G.) are
implemented to the minimum detail to ensure
maximum reliability.
e upper inspection ange ensures practical
control of the storage tank unit and the coil heat
exchanger pipe and easy internal cleaning.
e domestic hot water connections are placed
on the ange cover (cold inlet and hot outlet), the
Magnesium Anode cap inclusive of the same, is
provided as standard for the internal protection
of the storage tank from possible corrosion is
located on the side of the UB INOX 200 V2
storage tank, in the other models is placed on
the inspection ange.
N.B.: annually check (e.g. the Authorised
Technical Assistance centre) eciency of the
sacrificial anodes. The storage tank unit is
prepared for introduction of the domestic hot
water pump tting.

AND MAINTENANCE.
2.1 CLEANING AND MAINTENANCE. Attention: to preserve integrity of the storage
tank unit and keep the safety features, performance and reliability, which distinguish it,
unchanged over time, you must at least execute
maintenance operations on a yearly basis in
compliance with what is stated in the relative
point at “annual check and maintenance of the
appliance”, in compliance with national, regional,
INSTALLERUSER
or local standards in force. Annual maintenance
is essential to validate the Immergas warranty.
We recommend stipulating a yearly cleaning
and maintenance contract with an authorised
local rm.
2.2 EMPTYING THE STORAGE TANK UNIT.
To drain the storage tank, use the special
valve in the lower part of the storage tank
(Part. 5 Fig. 1-6).
Before draining, ensure that the DHW inlet
valve is closed.
2.3 CASE CLEANING.
Use damp cloths and neutral detergent to clean
the storage tank casing. Never use abrasive or
powder detergents.
2.4 DECOMMISSIONING.
In the event of permanent shutdown of the storage tank, contact an authorised company for the
relative operations, among other things making
sure that water supply is disconnected.
At the end of its service life the appliance must
not be disposed of like normal household waste
nor abandoned in the environment, but must
be removed by a professionally authorised
company. Contact the manufacturer for disposal
instructions.

- loosen the screws (2) and pull the front panel
outwards (3);
- loosen the screws (4) of the side pieces (5)
positioned on the top and in the lower part
of the side pieces themselves. Aer having
INSTALLERUSER
released them from the screws, they can be
removed by pulling them forward and then
upwards.
3.4 REPLACING THE ANODE.
e magnesium anode (Part. 3 Fig. 1-6), present
in the storage tank, must be replaced every year
