Air/water heat pump

NIBE F2120

NIBE F2120 is an inverter-controlled air/water heat pump

which represent a real breakthrough when it comes to

efficiency. With a seasonal performance factor in excess

of 5.0* , the heat pump provides more than five times as

much heat per year as an electric heater with the same

energy consumption. NIBE F2120 provides optimized

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.

Good to know about NIBE F2120

If there is a risk of snow slip from roof, a protective roof or

cover must be erected to protect the heat pump, pipes and

wiring.

Installation area

The distance between F2120 and the house wall must be at least 350 mm, but not more than 500 mm in locations that are

exposed to the wind. The free space above F2120 must be at least 1,000 mm. The free space in front must be at least

1,000 mm for any future servicing.

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

Installed before connection "heating medium return" (the

lower connection) on the vacuum pump.

•reversing valve.

The image shows connection to the control module.

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.
