savings since the heat pump automatically adapts to your
home’s output requirements all year round.
NIBE F2120 has a class leading working range and deliver a supply tem-
perature of up to 65°C. Even at outdoor temperatures of as low as -25°C,
it still provides a supply temperature of up to 63°C, while the noise level
stays low. NIBE F2120 has three-phase connection, which simplifies
electrical installation.
Thanks to smart technology, the product gives you control over your
energy consumption and will be a key part of your connected home. The
efficient control system automatically adjusts the indoor climate for high
comfort, and you do nature a favour at the same time.
•Breakthrough in efficiency with a seasonal performance factor
of over 5.0.*
•Class leading working range, supply temperature of up to 65°C,
and 63°C at an outdoor temperature of -25°C.
•Low noise level, even at full output.
*NIBE F2120 has a rating of SCOP > 5.0 (Average climate, Low temperature) and SCOP
4.3 (Colder climate, Low temperature) in accordance with European standard EN
14825:2013, i.e. the standard for determining the reference seasonal performance
factor, SCOP. Applies to F2120-16 and -20.

Installation method
F2120 – a part of your climate system where F2120 is inten-
ded to be combined with one of the indoor modules VVM or
the control modules SMO.
Together with an indoor module, F2120 creates a complete
heating/cooling and hot water unit. Our flexible indoor
modules provide efficient heating and high hot water per-
formance. VVM indoor modules are complete with a smart
and user-friendly control system, hot water heater, addition-
al heat, self-regulating circulation pump, etc.
The control modules, SMO, offer a flexible system solution
that can be easily customised. For systems with SMO, differ-
ent components such as water heaters, additional heat and
other accessories can be selected to suit the installation's
requirements. Up to eight F2120 can be connected to a
SMO 40.
There is a wide range of system solutions and accessories
for NIBE indoor modules and control modules.

Transport
F2120 must be transported and stored vertically.
Ensure that the heat pump cannot fall over during transport.
Check that the heat pump has not been damaged during
transport.
LIFT FROM THE STREET TO THE SET UP
LOCATION
If the surface allows, the easiest method is to use a pallet
truck to move the heat pump to the installation area.
The centre of gravity is offset to one side (see print on the
packaging).
LEK
C:a 180 kg
Approx. 180 kg
If the heat pump needs to be transported across soft ground,
such as a lawn, we recommend using a crane truck that can
lift it to the installation location. When the heat pump is lifted
with a crane, the packaging must be intact.
If a crane truck cannot be used, the heat pump can be
transported on an extended sack truck. The heat pump must
be taken hold of from its heaviest side and two people are
required to lift it.
LIFT FROM THE PALLET TO FINAL POSITIONING
Before lifting remove the packaging and the securing strap
to the pallet.
Place lifting straps around each machine foot. Lifting from
the pallet to the base requires four persons, one for each
lifting strap.
Installation and positioning
•Place F2120 outdoors on a solid level base that can take
the weight, preferably a concrete foundation. If concrete
slabs are used they must rest on asphalt or shingle.
•The lower edge of the evaporator must not be lower than
the level of the average local snow depth. The base should
be at least 70 mm tall.
•F2120 should not be positioned next to noise sensitive
walls, for example, next to a bedroom.
•Also ensure that the placement does not inconvenience
the neighbours.
•F2120 must not be placed so that recirculation of the
outdoor air is possible. Recirculation entails reduced power
and impaired efficiency.
•The evaporator must be sheltered from direct wind / ,
which negatively affects the defrosting function. Place
F2120 protected from wind / against the evaporator.
•Small amounts of condensation water, as well as melt
water from defrosting, may be produced. Condensation
water must be led off to a drain or equivalent.
•Care must be exercised so that the heat pump is not
scratched during installation.

Inspection of the installation
Current regulations require the heating installation to be
inspected before it is commissioned. The inspection must
be carried out by a suitably qualified person and must be
documented. The above applies to closed heating systems.
If the heat pump is replaced, the installation must be inspec-
ted again.
Condensation water trough
The condensate drain pan collects and leads away the con-
densation water.
It is important for the heat pump’s function that the con-
densation water is led away and that the outlet for the
condensation water pipe is positioned so as to prevent
damage to the building. Condensation run-off should be
checked regularly, especially during the autumn. Clean if
necessary.
Pipe with heating cable for draining the condensate drip
tray is not included. To ensure the function, the accessory
KVR 11 should be used.
•The condensation water (up to 50 litres/24 hrs) that col-
lects in the trough should be routed away by a pipe to an
appropriate drain, it is recommended that the shortest
outdoor stretch possible is used.
•The section of the pipe that can be affected by frost must
be heated by the heating cable to prevent freezing.
Pipe with heating cable for draining the condensation
water trough is not included.
To ensure the function, the accessory KVR 11 should be
used.
•Route the pipe downward from the heat pump.
•The outlet of the condensation water pipe must be at a
depth that is frost free or alternatively indoors (with reser-
vation for local ordinances and regulations).
•Use a water trap for installations where air circulation may
occur in the condensation water pipe.
•The insulation must seal against the bottom of the con-
densation water trough.

Otherwise the stone caisson can be positioned directly under
the heat pump.
Drain indoors
Water seal
The condensation water is lead to an indoor drain (subject
to local rules and regulations).
When routing pipes indoors, condensation water pipes must
be insulated against condensation.
Route the pipe downward from the heat pump.
The condensation water pipe must have a water seal to
prevent air circulation in the pipe.

An undersized system can result in damage to the product
and lead to malfunctions.
F2120 can only operate up to a return temperature of about
55 °C and an outgoing temperature of about 65 °C from the
heat pump.
F2120 is not equipped with shut-off valves on the heating
medium side, rather these must be installed to facilitate any
future servicing. The return temperature is limited by the
return line sensor.
WATER VOLUMES
Depending on the size of your F2120, an available water
volume is required to prevent short operating times and to
enable defrosting. For the optimum operation of F2120, a
minimum available water volume of 10 litres multiplied by
the size number is recommended. E.g. F2120-12: 10 litres x
12 = 120 litres. This applies individually to heating and cooling
systems.

PIPE COUPLING, HEATING MEDIUM
You can find a list of compatible products in the section
"Compatible indoor modules (VVM) and control modules
(SMO)".
There is a difference between connection to a control
module compared with connection to an indoor module.
See the Installer Manual for the indoor module/control
module.
Vent the heat pump by the "heating medium supply" con-
nection (XL1) using the venting nipple on the enclosed flex-
ible hose.
Install as follows:
•expansion vessel
•pressure gauge
•safety valves
•drain valve
For draining the heat pump during prolonged power fail-
ures.
•non-return valve
Installations with only one heat pump: a non-return valve
is only required in those cases where the placement of
the products in relation to each other can cause self-cir-
culation.
Cascade installations: each heat pump must be fitted with
a non-return valve.
•charge pump
•shut-off valve
To facilitate any future servicing.
•enclosed filterball

Charge pump
The charge pump (not included in the product) is powered
and controlled from the control module. It has a built-in frost
protection function and, for this reason, must not be
switched off when there is a risk of freezing.
At temperatures below +2 °C the charge pump runs period-
ically, to prevent the water from freezing in the charge cir-
cuit. The function also protects against excess temperatures
in the charge circuit.
