For Home Owners

General

System description

Principle of operation

F2025 is an air/water heat pump, specially designed for the

Nordic climate. F2025 utilises the outside air so there is no

need for bore holes or coils in the ground. F2025 has an

automatic 2-stage capacity control of the fan (does not apply

to F2025-6 kW, which only has one fan speed).

F2025 is designed for **water based heating systems and

can be used together with most electric boilers, oil-fired

boilers or equivalent. The heat pump includes an advanced

control system for optimal control. F2025 is started by a start

signal from another controller or thermostat.

F2025 can also be controlled by a specially designed control-

ler, SMO 10 *. This connects and disconnects the additional

heat and controls switching between room heating and hot

water heating.

Accessories such as extra shunt group and pool control can

be connected if SMO 10 is present.

F2025 can both heat hot water effectively at high outdoor

temperatures and give a high output to the heating system

at low outdoor temperatures.

If the outdoor temperature drops to a level below the stop

temperature all heating must then occur with external addi-

tional heat.

F2025 is manufactured in four sizes: 6, 8, 10 and 14 kW.

The material has been chosen for a long service life and is

designed to withstand the Nordic outdoor conditions.

accessory for F2025*

When docking with F2025, a total water volume, incl.

boiler, radiators, pipes, etc. of at least 20 litres boiler water

per kW output on the heat pump is recommended.

The heating medium side and the hot water side must be

fitted with the necessary safety equipment in accordance

with the applicable regulations.

For Home Owners

System description

Maintenance routines

General

F2025 is equipped with control and monitoring equipment,

however some exterior maintenance is still necessary.

Make regular checks throughout the year that the inlet grille

is not clogged by leaves, snow or anything else. Check

through the cold part of the year to make sure that there

isn't a build up of snow and/or ice under F2025. The condens-

ation water trough KVT 11 accessory is available for manage-

ment and removal of condensation. Strong wind combined

with heavy snowfall can block the intake and exhaust air

grilles. Make sure that there is no snow on the grilles.

If necessary the outer casing can be cleaned using a damp

cloth. Care must be exercised so that the heat pump is not

scratched when cleaning. Avoid spraying water into the grilles

or the sides so that water penetrates into F2025. Prevent

F2025 coming into contact with alkaline cleaning agents.

!WARNING!

Insufficient maintenance can cause serious damage to

F2025 which is not covered by the guarantee.

LEK

Keep free of snow and/or ice.

LEK

Prevent ice and/or snow building up under F2025.

LEK

Prevent snow building up and covering the grille on F2025.

F20254

For Home Owners

Maintenance routines

General points for the installation engineer

Transport and storage

F2025 should be transported and stored vertically.

Inspection of the installation

Current regulations require the heating installation to be in-

spected before it is commissioned. The inspection must be

carried out by a suitably qualified person and should be

documented. The above applies to closed heating systems.

If the heat pump is replaced, the installation must be inspec-

ted again.

Assembly

F2025 should be installed outdoors on a firm surface,

preferably a concrete foundation with ground stand or wall

mounting. The F2025 should not be positioned next to

sensitive walls, for example, next to a bedroom. Also ensure

that the placement does not inconvenience the neighbours.

Care must be exercised so that the heat pump is not

scratched during installation.

LEK

Do not place F2025 directly on the lawn or other non solid

surface.

Large amounts of condensation water as well as melt water

from defrosting can be produced. Provide good drainage at

the installation area and make sure water cannot run out

onto paths or the like during periods that ice can form. It is

also possible to install the accessory KVT 11, which is a col-

lecting trough for leading off condensation water. Condens-

ation water must be led off to a drain or similar.

LEK

Cirka 1 m

$SSUR[ 

Place F2025 on concrete pillars resting on macadma or

shingle for good drainage. The concrete pillars must be posi-

tioned so that the lower edge of the heat pump is at the

level of the average local snow depth, although a minimum

of 400 mm.

LEK

&RQGHQVDWLRQ ZDWHU

WURXJK

The distance between F2025 and the house wall must be at

least 350 mm. Clearance above F2025 should be at least one

metre. F2025 must not be placed so that recirculation

of outdoor air can occur. This causes lower output and

impaired efficiency.

For the Installer

General points for the installation engineer

Control

F2025 is equipped with an internal electronic controller that

handles all functions necessary for heat pump operations.

Accordingly, defrosting, stop at max/min temperature, con-

nection of the compressor heater as well as enabling the

heater for the drip pan, monitoring of motor protection and

pressure switches are controlled.

The number of starts and the operating time can also be

read.

The integrated controller is set during installation and can

be used during a service.

Under normal operation conditions the home owner does

not need to have access to the controller.

F2025 has an integrated electronic return line sensor that

limits the return temperature.

F2025 can also be switched on/off via signals from other

control equipment or a thermostat. If F2025 is controlled

from the accessory SMO 10 the control is described in the

instructions supplied.

SMO 10 communicates with F2025 which means that set-

tings and measurement values from F2025 can be adjusted

and read off in SMO 10 .

F20256

For the Installer

General points for the installation engineer

Pipe connections

General

Pipe installation must be carried out in accordance with cur-

rent norms and directives.

F2025 operates up to a return temperature of about 50 °C

and an outgoing temperature of about 58 °C from the heat

pump. Because F2025 is not equipped with shut off valves

these must be installed outside the heat pump to facilitate

any future servicing. The return temperature is limited by the

return line sensor and is adjusted on channel A2.

NOTE

The pipe work must be flushed before the heat pump

is connected, so that any contaminants do not damage

the components parts.

Pipe coupling heating medium circuit

F2025 can be connected to the heating system, see the

"Docking" section or one of the system solutions that can

be downloaded from the website www.nibe.eu.

The heat pump must be vented by the upper connection (70,

HM-out) using the venting nipple on the enclosed flexible

hose.

The supplied particle filter (SF) must be installed before the

inlet, i.e. the lower connection (71, HM-in) on F2025. All

outdoor pipes must be thermally insulated with at least

19 mm thick pipe insulation.

The charge pump must be operational, even if F2025

is not running, to prevent damage due to freezing.

The charge pump can also be controlled directly from F2025,

terminal (11), which takes the outdoor temperature into

consideration. Alternatively, the heat pump is connected to

an intermediate circuit with a heat exchanger, pump and

water with anti-freeze (does not apply to docking with

VVM300).

Shutoff (AV) and drain valves (TV) are fitted so that F2025

can be emptied in the event of prolonged power failures.

The supplied flexible hoses act as vibration dampers. The

flexible hoses are fitted so a slight bend is created, thus acting

as vibration damping.

Water volumes

When docking with F2025 a total water volume in the boiler

and accumulator of at least 20 litres boiler water per kW

output on the heat pump is recommended.

General

F2025 can be installed in several different ways. The requisite

safety equipment must be installed in accordance with cur-

rent regulations for all docked options.

See www.nibe.eu for more docking options.

When docking with F2025, a total water volume, in the

boiler and accumulator, of at least 20 litres boiler water per

kW output on the heat pump is recommended.

F2025 -6, -8 and -10 can be connected to VVM 300. F2025

is controlled by VVM 300. F2025 works with floating con-

densing against the heating system and prioritises hot water

charging in VVM 300.

If F2025 cannot meet the heating requirement, additional

heat is shunted in from VVM 300. If the outdoor temperature

drops below the set stop temperature, VVM 300 engages

and takes over heating.

NOTE

To prevent interference, sensor cables and communic-

ation cables must be separated (min 20 cm) from high

voltage cables when cable routing.
