frigerant leaks, electric shocks, fire and personal injury, as a result of a system malfunction.
Use original accessories and the stated components for the installation.
If parts other than those stated by us are used, water leaks, electric shocks, fire and personal
injury may occur as the unit may not work properly.
Install the unit in a location with good support.
Unsuitable installation locations can cause the unit to fall and cause material damage and
personal injury. Installation without sufficient support can also cause vibrations and noise.
Ensure that the unit is stable when installed, so that it can withstand earthquakes
and strong winds.
Unsuitable installation locations can cause the unit to fall and cause material damage and
personal injury.
The electrical installation must be carried out by a qualified electrician and the
system must be connected as a separate circuit.
Power supply with insufficient capacity and incorrect function can cause electric shocks and
fire.
Do not perform any repairs yourself. Consult the dealer if the system requires repair.
Incorrectly performed repairs can cause water leakage, refrigerant leakage, electric shocks
or fire.
Consult the dealer or an expert regarding removal of the heat pump.
Incorrect installation can cause water leakage, refrigerant leaks, electric shocks or fire.
Switch off the power supply in the event of a service or inspection.
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.

5NIBE™ F2300Chapter 1 | Important information

- 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, con-
taining 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.
Insulate the unit's connection pipes so that the ambient air moisture does not
condense on them.
Insufficient insulation can cause condensation, which can lead to moisture damage on the
roof, floor, furniture and valuable personal property.
Do not install the outdoor unit in a location where insects and small animals can
inhabit.
Insects and small animals can enter the electronic parts and cause damage and fire. Instruct
the user to keep the surrounding equipment clean.
Dispose of any packaging material correctly.
Any remaining packaging material can cause personal injury as it may contain nails and
wood.
Do not touch any buttons with wet hands.
This can cause electric shocks.
Do not shut off the power supply immediately after operation has start.
Wait at least 5 minutes, otherwise there is a risk of water leakage or breakdown.

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:
႑Efficient scroll compressor
New efficient scroll compressor that operates at temperatures down to
-25°C.
႑Intelligent 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.
႑Fan
F2300 has an automatic 2-step capacity regulator for the fan.
႑Long service life
The material has been chosen for a long service life and is designed to
withstand the Nordic outdoor conditions.
႑Many possibilities
F2300 can also be used together with most electric boilers, oil boilers or
similar.

11NIBE™ F2300Chapter 2 | The heat pump – the heart of the house

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 distributed 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 evapor-
ator 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 wa-
ter'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.
NIBE™ F2300Chapter 2 | The heat pump – the heart of the house12

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 information.
13NIBE™ F2300Chapter 2 | The heat pump – the heart of the house

Maintenance of F2300
Regular checks
When your heat pump is located outdoors some external maintenance is re-
quired.
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.
LEK
Prevent snow building up and covering the grille on F2300.
LEK
Keep free of snow and/or ice.
NIBE™ F2300Chapter 2 | The heat pump – the heart of the house14

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 water trough
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 trough and drain.
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 installed 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 temper-
ature, 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:
႑Open 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.

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.
17NIBE™ F2300Chapter 2 | The heat pump – the heart of the house

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.
