If the power supply is not shut off, there is a risk of electric shocks and damage due to
the rotating fan.
Do not run the unit with removed panels or protection.
Touching rotating equipment, hot surfaces or high voltage parts can cause personal
injury due to entrapment, burns or electric shocks.
Cut the power before starting electrical work.
Failure to cut the power can cause electric shocks, damage and incorrect function of
the equipment.
Care
Do not use the unit where water splashes may occur, for example in laundries.
The indoor section is not waterproof and electric shocks and fire can therefore occur.
Do not use the unit for specialist purposes such as for storing food, cooling precision
instruments, freeze-conservation of animals, plants or art.
This can damage the items.
Do not install the outdoor unit in the locations stated below.
- Locations where leakage of combustible gas can occur.
- Locations where carbon fibre, metal powder or other powder that can enter the air.
- Locations where substances that can affect the unit, for example, sulphide gas, chlorine,
acid or alkaline substances can occur.
- Locations with direct exposure to oil mist or steam.
- Vehicles and ships.
- Locations where machines that generate high frequency harmonics are used.
- Locations where cosmetic or special sprays are often used.
- Locations that can be subjected to direct salty atmospheres. In this case, the outdoor
unit must be protected against direct intakes of salty air.
- Locations where large amounts of snow occur.
- Locations where the system is exposed to chimney smoke.
If the bottom frame of the outdoor section is corroded, or in any other way dam-
aged, due to long periods of operation, it must not be used.
Using an old and damaged frame can cause the unit to fall and cause personal injury.
Do not allow the drainage pipe to exit into channels where poisonous gases,
containing sulphides for example, can occur.
If the pipe exits into such a channel, any poisonous gases will flow into the room and
seriously affect the user's health and safety.

F2300 - An excellent choice
F2300 is an air/water heat pump specially developed for the Nordic climate,
which utilises the outside air so there is no need for bore holes or coils in
the ground.
The heat pump is intended for connection to water borne heating systems
and 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 additional heat.
Excellent properties for F2300:
■Efficient scroll compressor
New efficient scroll compressor that operates at temperatures down to
-25°C.
■Intelligent control
Integrated intelligent control for optimum control of the heat pump. At
a start signal from an NIBE indoor module or thermostat F2300 is started.
■Fan
F2300 has an automatic 2-step capacity regulator for the fan.
■Long service life
The material has been chosen for a long service life and is designed to
withstand the Nordic outdoor conditions.
■Many possibilities
F2300 can also be used together with most electric boilers, oil boilers
or similar.
■Draining
F2300 has been prepared to lead off the condensation water.

NIBE™ F2300Chapter 2 | The heat pump – the heart of the house12

An air/water heat pump can use the outdoor air to heat a property. The
conversion of the outdoor air's energy to property heating occurs in three
different circuits. In the brine circuit, (1) , free heat energy is retrieved from
the surroundings and transported to the heat pump. In the refrigerant
circuit, (2) , the heat pump increases the retrieved heat's low temperature
to a high temperature. In the heating medium circuit, (3) , the heat is dis-
tributed around the house.
Outdoor air
The outdoor air is sucked into the heat pump.
A
The fan then routes the air to the heat pump’s evaporator. Here, the air
releases the heating energy to the refrigerant and the air's temperature
drops. The cold air is then blown out of the heat pump.
B
Refrigerant circuit
A gas circulates in a closed system in the heat pump, a refrigerant, which
also passes the evaporator. The refrigerant has a very low boiling point.
In the evaporator the refrigerant receives the heat energy from the outdoor
air and starts to boil.
C
The gas that is produced during boiling is routed into an electrically
powered compressor. When the gas is compressed, the pressure increases
and the gas's temperature increases considerably, from 5 °C to approx.
80°C.
D
From the compressor, gas is forced into a heat exchanger, condenser,
where it releases heat energy to the heating system in the house,
whereupon the gas is cooled and condenses to a liquid form again.
E
As the pressure is still high, the refrigerant can pass an expansion valve,
where the pressure drops so that the refrigerant returns to its original
temperature. The refrigerant has now completed a full cycle. It is routed
to the evaporator again and the process is repeated.
F
Heat medium circuit
The heat energy that the refrigerant produces in the condenser is retrieved
by the climate system's water, heating medium, which is heated to 55 °C
(supply temperature).
G
The heating medium circulates in a closed system and transports the heated
water's heating energy to the house water heater and radiators/heating
coils.
H
The temperatures are only examples and may vary between different installations and
time of year.
13NIBE™ F2300Chapter 2 | The heat pump – the heart of the house

Contact with F2300
F2300 has an integrated control system that checks and monitors the heat
pump operation. At installation the installer makes the necessary settings
of the control system so that the heat pump will work optimally in your
system.
The heat pump is controlled in different ways depending on what your
system looks like. If you have a NIBE indoor module heat pump operation
can be controlled from there. Refer to the relevant manual for further in-
formation.
NIBE™ F2300Chapter 2 | The heat pump – the heart of the house14

Maintenance of F2300
Regular checks
When your heat pump is located outdoors some external maintenance is
required.
NOTE
Insufficient oversight can cause serious damage to F2300 which is not
covered by the guarantee.
Checking grilles
Check that the inlet grille is not clogged by leaves, snow or anything else
regularly throughout the year.
Pay extra attention in event of high winds or snowfall that may cause the
grille to be blocked.

15NIBE™ F2300Chapter 2 | The heat pump – the heart of the house

Cleaning the outer casing
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 F2300. Prevent F2300 coming into contact with alkaline
cleaning agents.
Condensation drain pan and condensation water pipe
The trough and drain pipe may require cleaning from leaves or similar
during the year.
Cleaning
1. Use the safety switch to cut the incoming electrical supply.
2. Release the trough using the quick release catches on the left and
right front edges. Keep in position at the rear edge without stretching
the power cable.
3. Clean drain pans and condensation water pipe/drains.
4. Reinstall the trough using the removal method in reverse order (see
point 2).
5. Switch on the safety switch again.
In event of long power cuts
In the event of prolonged power failures it is recommended that the part
of the heating system located outdoors is drained. Your installer has in-
stalled a shut off and drain valve to facilitate this. Call and ask your installer
if you are unsure.
Saving tips
Your heat pump installation produces heat and/or hot water. This occurs
via the control settings you made.
Factors that affect the energy consumption are, for example, indoor tem-
perature, hot water consumption, the insulation level of the house and
whether the house has many large window surfaces. The position of the
house, e.g. wind exposure is also an affecting factor.
Also remember:
■Open the thermostat valves completely (except those thermostats in
the rooms that are to be kept cooler for various reasons, e.g. bedrooms).
The thermostats slow the flow in the heating system, which the heat
pump wants to compensate with increased temperatures. It then works
harder and consumes more electrical energy.
■Reduce or adjust the settings for heating in any external control systems.

cleaner, engine block heater = 6240 kWh domestic electricity/year.
Energy meter
Check the accommodation's energy meter regularly, preferably once a
month. This will indicate any changes in power consumption.
Newly built houses usually have twin energy meters, use the difference to
calculate your domestic electricity.
New builds
Newly built houses undergo a drying out process for a year. The house
can then consume significantly more energy than it would thereafter.
After 1-2 years the heating curve should be adjusted again, as well as the
heating curve offset and the building's thermostat valves, because the
heating system, as a rule, requires a lower temperature once the drying
process is complete.
