1STORAGE TANK UNIT INSTALLATION
1.1 INSTALLATION
RECOMMENDATIONS.
e place of installation of the appliance and
relative Immergas accessories must have suitable
features (technical and structural) such to allow
(always in safety, efficiency and comfortable
conditions):
- installation (according to the provisions of the
technical legislation and technical regulations);
- maintenance operations (including scheduled,
periodic, routine and special maintenance);
- removal (to outdoors in the place for loading
and transporting the appliances and compo-
nents) as well as their eventual replacement
with appliances and/or equivalent components.
Only professionally enabled companies are au-
thorised to install Immergas appliances.
Installation must be carried out according to
regulation standards, current legislation and
in compliance with local technical regulations
and the required technical procedures. Before
installing the storage tank unit, ensure that it is
delivered in perfect condition; if in doubt, contact
the supplier immediately. Packing materials (sta-
ples, nails, plastic bags, polystyrene foam, etc.)
constitute a hazard and must be kept out of the
reach of children.
If the storage tank unit is installed inside or
between cabinets, ensure there is sucient space
for normal servicing. It is advisable to leave an
adequate gap between the storage tank casing
and the sides of the cabinet.
A space of at least 650 mm is to be le in the
upper part and 450 mm in the inspection and
sacricial anode connection areas.
In the event of a malfunction, fault or incorrect
-operation, disable the storage tank unit and
contact an authorised company (e.g. the Au-
thorised Technical Assistance centre, which has
specically trained sta and original spare parts).
Do not attempt to modify or repair the appliance
alone. Immergas is to comply with the conditions
specied in the conventional warranty contract
during the period of validity of the said warranty.
Failure to comply with the above implies personal
responsibility and invalidates the warranty.
• Installation regulations: previously check the
features of the place of installation regarding
clearance and total weight of the accumulation,
if necessary placing a support surface under the
storage tank in order to optimise distribution
of the weight. ese storage tanks have been
designed only for oor installation; they must
be used for the storage of domestic hot water
for domestic and similar uses. ey have not
been designed for wall installation. Make sure
that the volume and pre-charged pressure of
the expansion tank of the secondary circuit are
suitable for the system;
N.B.: It is mandatory to have a properly sized
safety valve and expansion vessel to place on
both hydraulic circuits.
Important: this storage unit is used to produce
and store hot water; it must therefore be con-
nected to a heating plant, to a domestic hot
water distribution network and a water system,
which are compatible with its performance and
power. e materials used for the installation and
connection must be completely compatible with
the minimum features requested for solar use.
It must be installed in an environment where the
temperature cannot fall below°C. It must not be
exposed to atmospheric agents.

1.3 HYDRAULIC CONNECTION.
Before making the connections, all of the system
piping must be washed thoroughly to remove
any residues that could compromise the good
functioning of the storage tank. Water connec-
tions must be made in a rational way.
N.B.: while performing the connection, set up
a drain tting and an interception cock at the
cold water inlet (AF) to facilitate maintenance
operations. e storage tank safety valve outlet
must be connected to a draining funnel. If this
is not the case, the storage tank manufacturer
declines any liability in the event of ooding if
the drain valve cuts in.

sion. e insulating material on Inoxstor 200
and 300 litre models is about 60 mm thick and
about 80 mm thick on Inoxstor 500 litre model.
- Boiler protection: this storage tank is manufac-
tured with a stainless steel casing and bottom,
which guarantees a long life. e assembly
concepts and welding (T.I.G.) are implemented
to the minimum detail to ensure maximum
reliability.
- Eciency: the coiled heat exchange surface is
sized to supply large quantities of hot water.
- e storage tank has two seats to include the
sacricial anode, which is supplied as standard
to protect the inner part of the storage tank
against corrosion; one is on the upper part and
the other is on the side of the storage tank.

2USER AND MAINTENANCE INSTRUCTIONS
2.1 CLEANING AND MAINTENANCE.
Attention: to preserve integrity of the storage
tank unit and keep the safety features, per-
formance 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,
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 FUNCTIONING.
is storage tank allows easy provisioning of
water for domestic use and industrial use.
e storage tank is connected to the water dis-
tribution network via the cold water tting and
to the utilities via the hot water tting.
If a utility withdraws hot water, the cold water
enters the tank where it is heated to the tempera-
ture set on the thermostat.
It is recommended to adjust the temperature
between 60 and 65°C because this temperature
guarantees the best performance of the storage
tank unit and at the same time ensures:
- maximum hygiene
- maximum aordability
- delay in lime scale formation
e DHW in the storage tank is heated with
the passage of CH/solar water, which circulates
inside the coils inside the storage tank unit itself.
In all cases the maximum temperature inside the
storage tank unit must not exceed 99°C.
2.3 EMPTYING THE STORAGE TANK
UNIT.
To drain the storage tank, use the special drain-
ing valve in the lower part of the storage tank.
Before draining, ensure that the DHW inlet
valve is closed.
2.4 CASE CLEANING.
To clean the outer parts of the storage tank, just
use a cloth dampened with product suitable for
the purpose that can be found on the market.
Abrasive, solvents, petrol and alcohol products
are not recommended.
2.5 DECOMMISSIONING.
In the event of permanent shutdown of the stor-
age 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.

3.2 YEARLY CONTROL AND
MAINTENANCE OF THE STORAGE
UNIT.
e following checks and maintenance should
be performed at least once a year.
- Visually check for water leaks or oxidation
from/on connections;
- Check visually that the safety and control
devices have not been tampered with and in
particular:
- adjustment probes;
- expansion vessel;
- domestic hot water side safety valve;
- Check integrity of the storage tank sacricial
anodes;
- In the case of particularly hard water, decalci-
cation of the storage tank is recommended
at least once a year. To perform this operation
the tank must be emptied through the draining
valve and then remove the ange in order to
access the inside and use a plastic or wooden
spatula to remove the most resistant deposits
and then clean and rinse with a jet of water.
- During the cleaning phase pay particular at-
tention not to damage the internal protection
of the tank.
