The storage tanks can be installed in any room pro-
tected against a temperature drop below 0°C, which
will prevent freezing of water in the tanks. It should
be installed in a convenient place for the user (eg
basement, boiler room, etc.), in a way that will enable
easy maintenance or servicing in the future. Consider
the  lled 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. To avoid loss of heat energy, all hydraulic pipes
should be thoroughly insulated.
Removable housing with thermal insulation facilitates
transport and installation of the storage tank. Disas-
sembly the housing in the following order (see Fig. 8):
After the installation of the storage tank in its  nal lo-
cation, reinstall the removed components in the re-
verse order.
The storage tank stands on three feet that can be ad-
justed within the range from 0 to 15 mm to level the
tank.
1. Remove the Temperature gauge, plug of the
heating element connector pipe and blanking
plate of the inspection opening.
2. Remove the upper cover of the housing together
with thermal insulation.
3. Remove the plugs from the connector pipes and
black bushings.
4. Remove the  xing screws and the strip connect-
ing the housing jacket.
5. Remove the jacket surrounding the tank (housing
jacket.)
6. Remove the four-piece thermal insulation.
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 speci ca-
tion of the protective anodes available at NIBE, see
Section 6 “Accessories and Spare Parts”.
For the minimum clearances to be observed
when installing the storage tank, see Table 3.

8Chapter 3 | Installation BA-ST 9022-9100-FE
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 10 bar (BA-
ST 9022-FE up to 6 bar)(see Table 6 Technical data).
Install 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 ac-
cordance with the installation diagram (see Fig. 9, 10,
11.)
Pressure increases during heating the water in the
storage tank. Therefore, the appropriate safety valve
must be installed in each storage tank, at the cold
water inlet that will protect the storage tank against
overpressure. During heating the water, small and
temporary water  ow from the safety valve can oc-
cur, 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 out ow from
the safety valve to the sewerage or drain grate. The
safety valve out ow line should be installed with a
slope and be protected against water freeze, and it
should remain open to the atmosphere. The manu-
facturer is not responsible for  ooding the room as a
result of the valve operation.
Installation and commissioning of the storage
tank shall only be done by appropriately qual-
i ed installer. The installer should inform the
user of the functions of the product and pro-
vide the necessary information on its safe use.
CAUTION
When heating water, slight, temporary di-
scharge 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
Installation of necking of any kind (such as
reducers, dirt pockets, etc.) and cut-o valves
between the storage tank and the safety valve
is not allowed. Only a T-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
Installation of the appropriate safety valve in
the cold water supply line protecting the unit
against overpressure is mandatory!
CAUTION
Fig. 8 Housing and thermal insulation disassembly.
In order to minimize the fl ow of water from the
safety valve associated with the thermal ex-
pansion of the liquid, it is advisable to install
a suitable expansion vessel at the cold water
connection (see Fig. 9, 10, 11 item CM1.)
INFORMATION
We recommend installing a strainer in order
to protect the pumps, check valve and the
components of the heating system.

• Check the operation of the safety valve as de-
scribed by the manufacturer of the valve.
• Clean the inside of the storage tank periodically.
Cleaning intervals depends, among other things,
on the hardness of the water present in a given
area.
• To ensure optimum protection of the storage tank
against corrosion, we recommended checking
the level of wear of the isolated magnesium an-
ode once a year.
• The isolated protective anode earth conductor
must be connected to the steel components of
the storage tank (top bottom of the tank). Other-
wise, the tank will not be protected against cor-
rosion.
• In order to eliminate any odour of hydrogen sul-
phide (caused by bacteria in the oxygen decient
water), we recommend observing the periodic
cleaning of the tank and replacement of the elec-
trode and, in addition, from time to time and in-
dependently of the normal temperature setting,
overheating the water in the tank to a tempera-
It is possible to grow Legionella bacteria in
domestic hot water. To eliminate this danger,
it is recommended to heat the water to 70oC
once a week and keep it at this temperature
for 5 minutes.
CAUTION
Warnings and Practical
Requirements
We recommend the following
1. Open the cold water cut-o󰀨 valve at the inlet and
the hot water intake point.
2. Fill the storage tank until obtaining uniform
water outow at the hot water intake point. Close
the intake points.
3. Check tightness of the entire system.
When properly lled and vented, the storage tank is
ready to use.
After the installation and levelling the tank, follow the
procedure below (for the connector pipe numbers,
refer to Fig. 3 and Fig. 5):
Fill the storage tank with water and vent it after mak-
ing correct connections.
1. Remove protecting plugs from the connector
pipes
2. Connect the hot water intake line (XL4).
3. Connect the cold water supply line together with
the required safety valves (XL3).
4. If the system has the hot water circulation
system, connect it to the connector pipe (XL5).
Otherwise, plug the pipe.
5. Connect all temperature sensors (UA1-3).
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.
Filling and venting the hot water storage tank:
4 Connection and
start-up
Connection
The storage tank connections may not be
made of materials more precious than car-
bon steel due to the increased electrochem-
ical corrosion. This applies to connector
pipes (ttings) contacting the tank connector
pipe thread. Preferably, use galvanized pipe
connectors (ttings.)
CAUTION
If there is an electric heating module installed
in the storage tank, ll the tank with water be-
fore connecting it to the electrical installation.
CAUTION
Open the hot water intake valves before
heating the system up for the rst time or af-
ter a longer break in its operation in order to
check whether the storage tank is lled with
water and the cut-o valve at the cold water
inlet is not closed.
CAUTION
Start-Up
Thermal Insulation of the System
We recommend connecting the tank connec-
tor pipes with the system lines by means of
unions to allow disconnection of the tank, if
required.
INFORMATION
No thermal insulation, its inadequate thick-
ness or insulation made of improper materi-
als will degrade the thermal insulation of the
installation.

Connection and start-up
Maintenance
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
protective magnesium anode
• Cleaning of the storage tank
Storage tanks of BA-ST Series are, in order to protect
them against corrosion, coated inside with ceramic
enamel and in addition, protected with isolated pro-
tective magnesium anode. The anode corrodes  rst
under normal operation, thus protecting the storage
tank jacket. Therefore, you have to inspect its condi-
tion from time to time. Corrosion rate of the protective
anode is di󰀨 erent and depends upon the quality of
water in the area. We recommend checking the pro-
tective anode condition once a year in order to ensure
optimum corrosion protection.
• Activate the heating medium circuit or electric
heating unit if the tank is not  lled with water.
• Use the storage tank, if you  nd any malfunction
of the safety valve.
• Install any device (such as cut-o󰀨 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.
Check the safety valve performance as spec-
i ed by the valve manufacturer periodically
(min. every 14 days) or before each start-up
of the heater after decommissioning.
CAUTION
The use of the isolated anode allows you 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 simpli es operation and additionally
contributes to the reliability and long lifetime.

ture above 70 °C. This also eliminates the risk of
Legionella bacteria growth.
• In the systems with the electric heating unit, en-
sure that the electrical installation is properly pro-
tected by protective circuit.
• When heating water using a coil, limit the tem-
perature of the heating medium to 80°C, it will
be possible to avoid turning on the temperature
limiter.
• In order to reduce the risk of scalding with water,
we recommend installing a anti-scalding valve.
• Report any malfunctions in the storage tank oper-
ation to the authorized service centres.
In order to check the degree of wear of the anode, do
the following (see Fig. 13):
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 signi cantly corroded (above 50 % loss),
replace it immediately. Connect the anode protective
conductor to the tank after the measurement.
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

Magnesium Anode Wear

12 BA-ST 9022-9100-FEChapter 5 | Maintenance
When replacing the magnesium anode, follow the
procedure below (see Fig. 14):
1. In units with the electric heating unit installed, dis-
connect power from the unit  rst.
2. Wait until the water inside cools down.
3. Cut-o󰀨 the hot water supply and drain some wa-
ter from the tank through the drain valve (see Fig.
9, 10, 11 item QM1).
4. Remove the housing cover together with thermal
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.
Replace the protective magnesium anode every 18
months (regardless the measurement). In replace-
ment of the magnesium anode, you can use a tita-
nium anode, which you do not need to replace. Its
assembly should be carried out in accordance with
the assembly manuals of the anode manufacturer.
The replacement of the magnesium protec-
tive anode should be carried out at least once
every 18 months during the warranty period.
After the warranty expires, the frequency of
replacing the protective anode depends on
the degree of wear .Timely replacement and
correct installation are a condition for main-
taining the tank warranty.

Once making the above steps, the storage tank is
ready to use.
Cleaning of the Storage Tank
During the use of the tank, the so-called boiler scale
precipitation occurs from the heated water. The
amount of deposited stone depends on the hardness
of water, working temperature and time of use. Cov-
ering the heating surfaces with stone reduces their
heating e󰀩 ciency, increases energy consumption
and lengthens the heating time. It is recommended
to clean the tank from accumulated deposits at a fre-
quency of at least once a year. In the case of hard or
very hard water, it is necessary to carry out cleaning
more frequently.
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 “Accessories
and Spare Parts”).
2. In storage tanks with the electric heating unit in-
stalled, disconnect power from the unit  rst.
3. Turn o󰀨 the heating devices supplying the stor-
age tank and wait until the water inside the tank
cools down.
4. Cut-o󰀨 the hot water supply and drain the storage
tank through the drain valve (see Fig. 9, 10, 11
item QM1)
5. Remove the inspection opening blanking plate
and gasket
6. Remove the inspection opening screws and
Ensure that the anode protective conductor
is connected to the storage tank top head
after installing the new isolated magnesium
anode. Lack of connection of the anode with
the tank will completely block the work of the
anode and the tank will be deprived of corro-
sion protection.
