STALLATION
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 components) as well as their eventual replacement
with appliances and/or equivalent components.
Only professionally enabled companies are authorised 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 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.
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 malfunctions, faults or incorrect
operation, turn the appliance o 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
responsibility 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.
Attention: 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.
"Anti-legionella" heat treatment of the Immergas
storage tank (activated by the specic function
present on the predisposed thermoregulatory
systems): during this stage, the temperature of
the water inside the storage tank exceeds 60°C
with a relative risk of burns. Keep this domestic
water treatment under control (and inform
the users) to prevent unforeseeable damage
to people, animals, things. If required install a
thermostatic valve on the domestic hot water
outlet to prevent scalding.

1.4 HYDRAULIC CONNECTION.
Before making the connections, all of the system
piping must be washed thoroughly to remove
any residues that could compromise the proper
operation 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 is not the case, the storage tank manufacturer declines any liability in
the event of ooding if the drain valve cuts in.
1.5 ELECTRICAL CONNECTION.
e storage tank has an IPX0D protection rating
for the entire appliance. Electrical safety of the
appliance is reached only when it is correctly connected to an ecient earthing system as specied
by current safety standards.
Attention: Immergas S.p.A. declines any responsibility for damage or physical injury caused by
failure to connect the storage tank to an ecient
earth system or failure to comply with the reference standards.
Also ensure that the electrical installation corresponds to maximum absorbed power specications as shown on the storage tank data-plate.
e storage tank unit is supplied complete with
an “X” type power cable without plug.
MAINTENANCE TECHNICIAN
Solar manifold probe connection.
Connect the solar manifold probe to pins 45
and 46 on the terminal board (Fig.1-12 part. 17)
present inside the storage tank unit, paying attention to eliminate the resistance R15 as indicated
in the wiring diagram.
Storage tank connection to the boiler.
Connect the storage tank to the boiler as indicated in the wiring diagram, using a cable (not
present) to connect clamps 36 and 37 to the boiler
and to the storage tank.
Storage tank unit electric connection.
e power supply cable must be connected to a
230V ±10% / 50Hz mains supply respecting L-N
polarity and earth connection;
must also have a multi-pole circuit breaker with
class III over-voltage category. When replacing
the power supply cable, contact a qualied rm
, this network
(e.g. the Authorised Aer-Sales Technical Assistance Service).
For the main power supply to the appliance,
never use adapters, multiple sockets or extension leads.
Solar collector return probe connection (optional).
Connect the solar collector return probe to pins
8 and 7 on the terminal board present inside the
storage tank unit.
Attention: aer the connections have bee made,
the new system layout must be set on the solar
control unit as follows:
- press the “i” key for about 10 seconds;
- use the scrolling keys to nd parameter 27
(system conguration);
- press the “i” key for about 2 seconds.
- upon accessing parameter 27, you will nd that
conguration 1 is set; use the scrolling keys to
select conguration 2.
- press the “i” key to conrm the selected conguration.
1.6 FILLING THE SYSTEM.
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).
1.7 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
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 DHW couplings are positioned on the lid
of the ange (cold inlet and hot outlet). e
Magnesium Anode holder cap including the
same, supplied as per standard for the internal
protection of the storage tank from possible corrosion, is found on the side of the storage tank.
IMPORTANT NOTE: have the eciency of the
storage tank Magnesium Anode checked annually by a qualied rm. e storage tank unit is
prepared for introduction of the domestic hot
water pump tting.
1.8 DHW MIXING VALVE.
e thermostatic mixing valve mixes the cold
water with the hot water and via an internal wax
element, sensitive to the temperature, automatically controls the temperature of the mixed water
set by the user.
N.B.: for excellent management of the temperatures, the mixing valve must be set by the installer
at a safety temperature required by the user. e
outlet temperature of the domestic hot water
can also depend on the value set on the boiler,
however, the upper limit temperature value of
the domestic hot water is always determined by
the position of the mixing valve: knob position 1
= 42°C, 2 = 48°C, 3 = 54°C, 4 = 60°C (standard)
(the values indicated refer to a storage tank with
water at 70°C).
Any release of the three-way mixing valve. If
aer a long period of inactivity the three-way
mixing valve is blocked, it is necessary to act
manually on the knob positioned on the top of
the same in a way to release the shutter of the
valve itself.
