1.4 ELECTRICAL CONNECTION:
The 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 efficient earthing system as
specified by current safety standards.
Important: Immergas S.p.A. declines any
responsibility for damage or physical injury
caused by failure to connect the storage tank unit
to an efficient earth system or failure to comply
with the reference standards.
Also ensure that the electrical installation
corresponds to maximum absorbed power
specifications as shown on the storage tank
data-plate.
The storage tank unit is supplied complete with
an “X” type power cable without plug.
Solar collector probe connection.
Connect the solar collector probe to pins 45
and 46 onto the terminal board (Fig.1-5 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.
The power supply cable must be connected to
a 230V ±10% / 50Hz mains supply respecting
L-N polarity and earth connection
. This
network must also have an omnipolar circuit
breaker with class III over-voltage category.
When replacing the power supply cable, contact
a qualified technician (e.g. the Immergas After-
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.
Important: after 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 find parameter 27
(system configuration);
- press the “i” key for about 2 seconds.
- on enter ing p arameter 27, f ind t hat
configuration 1 is set; use the scrolling keys to
select configuration 2.
- press the “i” key to confirm the configuration
selected.
1.5 SYSTEM FILLING.
Once the storage tank has been connected, fill
the system via the boiler filling 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 filling valve when the boiler manometer
pointer indicates approx. 1.2 bar (see boiler
instruction book).
1.6 DOMESTIC HOT WATER STORAGE
TANK UNIT.
The 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. This storage tank
unit, manufactured with stainless steel casing and
bottoms, guarantees long duration through time.
The assembly concepts and welding (T.I.G.) are
implemented to the minimum detail to ensure
maximum reliability.
The upper inspection flange ensures practical
control of the storage tank unit and the coil heat
exchanger pipe and easy internal cleaning.
The DHW couplings are positioned on the lid
of the flange (cold inlet and hot outlet). The
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.
N.B.: every year a skilled technician (e.g.
Immergas Authorised After-sales Service),
must check the efficiency of the storage tank
unit Magnesium Anode. The storage tank unit
is prepared for introduction of the domestic hot
water pump fitting.
1.7 HYDRAULIC CIRCUIT RESISTANCE.
In order to guarantee sufficient DHW flow rate,
it is important to consider the resistance of the
storage tank hydraulic circuit to be coupled to
the boiler. (Fig. 1-3). For correct connection of
the storage tank unit to Immergas boilers, see the
boiler instruction book.
1.8 CIRCULATION PUMP.
The storage tank unit is supplied with a built-in
circulation pump with 3-position electric speed
control. With the circulation pump on first
speed it is probable that there is not sufficient
circulation. The circulation pump is already fitted
with a capacitor.
Pump release. If, after a prolonged period of
inactivity, the circulation pump is blocked,
unscrew the front cap and turn the motor shaft
using a screwdriver. During this operation, avoid
damage to the motor.
