2 Design
Vertical storage tank BA-ST 9030/9040/9050- 1FEDC with
a large surface coil is a pressure equipment, i.e. the pres-
sure within the storage tank and coil are equivalent to the
pressures in the corresponding systems.
Storage tank is made of high quality steel and is equipped
with one helical coil that can simultaneously operate with
independent heat source, e.g. a solar heating system,
fireplace with water jacket or central heating boiler. The
hot water tank is protected against corrosion by ceramic
coating and insulated protective magnesium anode. The
coil is not internally protected against corrosion. Thermal
insulation of the tank is a specially selected insulation
that provides excellent thermal insulation properties of all
devices. Storage tanks have aesthetic plastic housing, a
temperature indicator, inspection opening and connectors
for mounting electric heating unit and connecting the hot
water circulation.

Location of
the Storage Tank
Housing Disassembly
Storage tank can be installed in any room protect-
ed against temperatures below 0 °C and convenient
for the user (e.g. in the basement, boiler room, etc.).
Location and manner of installation must ensure trou-
ble-free maintenance and servicing of the unit in the fu-
ture. However, we recommend installation of the buffer
tanks in the immediate vicinity of the main heat source
in order to avoid unnecessary heat losses. Consider the
filled tank weight when selecting its location. As a rule,
select the device location in a way allowing the rational
routing of both the hot water and the heating lines. In-
sulate thoroughly all hydraulic lines and the storage tank
fittings in order to avoid any energy losses.
The storage tank stands on three feet that can be ad-
justed within the range from 0 to 15 mm to level the
tank.
If space for the installation of the magnesium bar an-
ode (used as standard), you can use the appropriate
titanium anode (that should be installed in accordance
with the anode manufacturer’s instructions) or the ap-
propriate magnesium chain anode. For the specifica-
tion of the protective anodes available at NIBE, see
Section 6 Accessories and Spare Parts.
Removable housing with thermal insulation facilitates
transport and installation of the storage tank. Disas-
sembly the housing in the following order (see Fig. 6):
After the installation of the storage tank in its final loca-
tion, reinstall the removed components in the reverse
order.

Chapter 3 |
Protection against overpressure shall be made in ac-
cordance with the relevant regulations in force.
Connect the storage tank to the water supply system
of water pressure at least 1 bar and max 6 bar and to
the heating systems where parameters of the heat-
ing medium may not exceed the allowable operating
conditions of the coil (see Table 4 Technical data). In-
stall a pressure reducer if the pressure at the cold
water inlet to the tank is higher than allowed.
Connect the heating and water supply systems in
accordance with the installation diagram (see Fig. 7.)
Pressure increases during heating the water in the
storage tank. Therefore, the appropriate safety valve
must be installed in storage tank, at the cold water in-
let that will protect the storage tank against overpres-
sure. During heating the water, small and temporary
water flow from the safety valve can occur, which
indicates that the pressure has increased above the
rated value, which triggered the valve. This may in no
way be prevented. Blocked safety valve can cause
equipment failure. Drain the outflow from the safe-
ty valve to the sewerage or drain grate. Safety valve
drain line should be installed with a decline, in an en-
vironment free of freezing and remain open to the
atmosphere. The manufacturer is not responsible for
flooding the room through the safety valve.

IMPORTANT
Installation and commissioning of the stor-
age tank shall only be done by appropriately
qualified installer. The installer should in-
form the user of the functions of the prod-
uct and provide the necessary information
on its safe use.
IMPORTANT
The coil in BA-ST 9030-9050-1FEDC storage
tanks is not internally protected against corro-
sion. The coil may only be filled with a heat-
ing medium (heating water) that meets the
requirements of VDI 2035 part 1 and 2.
TIP
In order to minimize the flow of water from
the safety valve associated with the ther-
mal expansion of the liquid, it is advisable
to install a suitable expansion vessel at the
cold water connection (see Fig. 7 item 9.)
TIP
We recommend installing a strainer in order
to protect the pumps, check valve and the
components of the heating system.
CAUTION
Installation of the appropriate safety valve
in the cold water supply line protecting the
unit against overpressure is mandatory!

4 Connection and start-up
Connection
Start-Up TIP
We recommend connecting the tank con-
nector pipes with the system lines by
means of unions to allow disconnection of
the tank, if required.
CAUTION
If there is an electric heating module in-
stalled in the storage tank, fill the tank with
water before connecting it to the electrical
installation.
CAUTION
The storage tank connections may not
be made of materials more precious than
carbon steel due to the increased electro-
chemical corrosion. This applies to con-
nector pipes (fittings) contacting the tank
connector pipe thread. Preferably, use gal-
vanized pipe connectors (fittings.)
CAUTION
The plug on the connection pipe of the heat-
ing module is an exploitation element, there-
fore it is necessary to check its tightness
before using the tank.
CAUTION
Installation of necking of any kind (such as re-
ducers, dirt pockets, etc.) and cut-off valves
between the storage tank and the safety
valve is not allowed. Only aT-pipe with a drain
valve and a T-pipe with an expansion vessel
may be installed in these line sections.
CAUTION
Never block the safety valve or drain line.
This can cause a dangerous overpressure
in the storage tank.
CAUTION
When heating water, slight, temporary dis-
charge from the safety valve can occur. This
is a correct safety valve function. Any attempt
to interfere in its operation can lead to the
danger and destruction of the storage tank.
CAUTION
Never use the equipment with clogged
safety valves.

Warnings and Practical
Recommendations
Thermal Insulation of
the System
• Check the operation of the safety valve as de-
scribed by the manufacturer of the valve in order
to check whether it is not clogged.
• Clean the inside of the storage tank periodically.
Cleaning intervals depends on the hardness of
the water present in a given area.
• To ensure optimum protection of the storage
tank against corrosion, we recommended check-
ing the level of wear of the isolated magnesium
anode once a year.
• In the systems with the electric heating unit, en-
sure that the electrical installation is properly pro-
tected by protective circuit.
• In order to eliminate any odour of hydrogen sul-
phide (caused by bacteria in the oxygen deficient
water), we recommend observing the periodic
cleaning of the tank and replacement of the an-
ode and, in addition periodically increase the hot
water temperature in tank to prevent bacterial
growth.
• Limit the setpoints of the heating medium tem-
perature controllers in the storage tank supply
lines to 80 °C in order to avoid triggering of the
thermal cut-off in the electric heating module.
• In order to reduce the possibility of scalding by
the water, we recommended to set the water
heating temperature in the storage tank (of both
the heating unit and the coil) so, that it does not
exceed 60 °C. This will also help to extend the life
of the storage tank.
• Report any malfunctions in the storage tank op-
eration to the authorized service centres.You can
find the complete list of our authorized service
centres at our website.
• Activate the heating medium circuit or electric
heating unit if the tank is not filled with water.
• Use the storage tank, if you find any malfunction
of the safety valve.
• Install any device (such as cut-off and/or check
valves, etc.) between the storage tank and the
safety valve (except T-pipes).
• Make any unauthorized repairs.
• Stop water leaks from the safety valve.
• When heating with only the electric unit, the coil
circuits may not be isolated.
We recommend the following:
It is forbidden to:
In order to minimize thermal energy losses, insulate
all connector pipes, pipelines and temperature sensor
covers thoroughly after the installation of the unit and
performance of the leak proof test. For this purpose,
use thermal insulation of correctly selected thickness
and thermal insulation parameters.
TIP
Lack of thermal insulation, its incorrect thick-
ness or insulation made of inadequate ma-
terials will cause decrease of thermal insu-
lation properties of the unit and the system.
CAUTION
To prevent bacterial growth we recommend
to make sure a periodically increase of hot
water temperature for a shorter time at reg-
ular intervals e.g. every 14th day.
CAUTION
Systematic admission of fresh, untreated
water to the heating circuit (coil) increases
the risk of corrosion inside the coil.
CAUTION
Open the hot water intake valves before
heating the system up for the first time or
after a longer break in its operation in order
to check whether the storage tank is filled
with water and the cut-off valve at the cold
water inlet is not closed.

Replacement of the
Protective Magnesi-
um Anode
Storage tank BA-ST 9030/9040/9050- 1FEDC with coil
is, in order to protect them against corrosion, coated
inside with ceramic enamel and in addition, protected
with isolated protective magnesium anode.The anode
corrodes first under normal operation, thus protecting
the storage tank jacket. Therefore, you have to inspect
its condition from time to time. Corrosion rate of the
protective anode is different and depends upon the
quality of water in the area. We recommend checking
the protective anode condition once a year in order to
ensure optimum corrosion protection.
Replace the protective magnesium anode every 18
months (regardless the measurement). Instead of the
magnesium anode, you can use the titanium anode. In-
stall it in accordance with the anode installation manual.
In order to check the degree of wear of the anode, do
the following (see Fig. 11):
Periodic inspections and maintenance are the condi-
tions of continuous operational readiness, reliability
and a long service life of the product.
Maintenance activities include the following:
• Routine inspections and replacement of the pro-
tective magnesium anode.
• Cleaning of the storage tank.
1. Remove the housing cover together with thermal
insulation.
2. Disconnect the connecting conductor (protective)
from the storage tank top head.
3. Connect an electric meter (range in mA) between the
protective conductor and the M5 threaded pin and
measure the intensity of the protective direct current.
Intensity of the protective direct current should not
be lower than 0.3 mA at full storage tank. If it is too
low, remove the anode and check its wear visually. If
the anode is significantly corroded (above 50 % loss),
replace it immediately. Connect the anode protective
conductor to the tank after the measurement.

TIP
The use of the isolated anode allowsyou to mon-
itor the degree of wear of the anode by measur-
ing the intensity of the protecting direct current
without having to remove it and empty the tank
(interrupting operation of the storage tank). This
solution simplifies operation and additionally con-
tributes to the reliability and long lifetime.
CAUTION
Check the safety valve performance as spec-
ified by the valve manufacturer periodically
(min. every 14 days) or before each start-up
of the heater after decommissioning.
CAUTION
If the current intensity measurements do not
indicate any wear of the anode, its max oper-
ating time is not longer than 18 months. The
anode should be replaced after this time.
CAUTION
Replace the protective magnesium anode
every 18 months. Its timely exchange and
proper installation are the conditions to
maintain the warranty on the storage tank.

Cleaning of
the Storage Tank
When replacing the magnesium anode, follow the
procedure below (see Fig. 10):
1. In units with the electric heating unit installed,
disconnect power from the unit first.
2. Switch the storage tank coil heaters OFF and
wait until the water inside cools down.
3. Cut-off the hot water supply and drain some
water from the tank through the drain valve (see
Fig. 7 item 4).
4. Remove the housing cover together with ther-
mal insulation (1).
5. Remove the anode protective conductor (2).
6. Remove the worn magnesium anode (3).
7. Screw the new magnesium anode.
8. Connect the anode protective conductor to the
storage tank.
9. Fill the tank with water and vent it as described
in par. Start-Up.
10. Check tightness of the installed anode.
11. Reinstall the thermal insulation and the housing
cover.
Boiler scale is precipitated from the heated water
during the storage tank operation. The amount of de-
posited scale depends on the water hardness, the
operating temperature and operating time. Heating
surfaces covered with boiler scale reduce the heat
output of the storage tank, increase power consump-
tion and extend the heating time. It is recommended
to clean the storage tank from deposits at least once
every two years. In the case of hard or very hard wa-
ter, cleaning should be carried out at shorter intervals.
Storage tank cleaning procedure:
1. Prepare a new inspection opening gasket. The
old gasket may not be reused (for the list of the
inspection opening gaskets, see Section 6 Acces-
sories and Spare Parts).
2. In storage tanks with the electric heating unit in-
stalled, disconnect power from the unit first.
3. Switch the storage tank coil heaters OFF and
wait until the water inside cools down.
4. Cut-off the hot water supply and drain the storage
tank through the drain valve (see Fig. 7 item 4).
5. Remove the inspection opening blanking plate
and gasket.
6. Remove the inspection opening screws and
flanged cover and flush the storage tank and re-
move accumulated sludge and lime slurry. If nec-
essary, remove lime deposits from the coil – this
guarantees a proper heat exchange. Pay special
attention to not damage the ceramic enamel
coating.
7. Replace a new gasket and the inspection open-
ing flanged cover. Screw tightening torque: 25±5
Nm.
8. Fill the tank with water and vent it as described
in par. Start-Up.
9. Check tightness of the inspection opening.
10. Replace the insulation and inspection opening
blanking plate.
Fig. 10 Replacement of the protective magnesium
anode.
Once making the above steps, the storage tank is
ready to use. Ensure that the anode protective con-
ductor is connected to the storage tank top head
after installing the new isolated magnesium anode.
Lack of contact between the anode and the tank will
interfere operation of the anode and the tank will not
be protected against corrosion.
Once cleaned, the unit is ready to use.
Connect the anode protective conductor to the M5
pin fixed to the top head of the storage tank.

TIP
Ensure that the anode protective conductor
is connected to the storage tank top head
after installing the new isolated magnesium
anode. Lack of contact between the anode
and the tank will interfere operation of the
anode and the tank will not be protected
against corrosion.
TIP
During mechanical cleaning, be careful to
not damage the enamel. In the case of
chemical cleaning, pay special attention to
neutralize the chemicals used for cleaning.
