Safety precautions
Caution
Install the system in full accordance with this installation
manual.
Incorrect installation can cause bursts, personal injury, water leaks,
refrigerant leaks, electric shocks and fire.
Observe the measurement values before working on the
cooling system, especially when installing in small rooms, so
that the limit for the refrigerant's density is not exceeded.
Consult an expert to interpret the measurement values. If the refri-
gerant density exceeds the limit, lack of oxygen can occur in the
event of any leak, which can cause serious accidents.
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.
Ventilate the working area well – refrigerant leakage may
occur during service work.
If the refrigerant comes into contact with naked flames, poisonous
gas is created.
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.
Use the stated cables for the electrical connection, tighten
the cables securely in the terminal blocks and relieve the
wiring correctly to prevent overloading the terminal blocks.
Loose connections or cable mountings can cause abnormal heat
production or fire.
Check, after completed installation or service, that no refriger-
ant leaks from the system in gas form.
If refrigerant gas leaks into the house and comes into contact with
an aerotemp, an oven or other hot surface, poisonous gases are
produced.
Switch off the compressor before opening/breaching the re-
frigerant circuit.
If the refrigerant circuit is breached /opened whilst the compressor
is running, air can enter the process circuit. This can cause unusually
high pressure in the process circuit, which can cause bursts and
personal injury.
Switch off the power supply in the event of a service or in-
spection.
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 in-
correct function of the equipment.
Care
Carry out the electrical installation with care.
Do not connect the ground lead to the gas line, water line, lightning
conductor or telephone line's ground lead. Incorrect grounding can
cause unit faults such as electric shocks due to short-circuiting.
Use main switch with sufficient breaking capacity.
If the switch does not have sufficient breaking capacity, malfunctions
and fire can occur.
NIBE™ F2300Chapter 1 | Important information2
1 Important information

Always use a fuse with the correct rating in the locations
where fuses are to be used.
Connecting the unit with copper wire or other metal thread can
cause unit breakdown and fire.
Cables must be routed so that they are not damaged by
metal edges or trapped by panels.
Incorrect installation can cause electric shocks, heat generation and
fire.
Do not install the unit in close proximity to locations where
leakage of combustible gases can occur.
If leaking gases collect around the unit, fire may occur.
Do not install the unit where corrosive gas (for example ni-
trous fumes) or combustible gas or steam (for example thinner
and petroleum gases) can build up or collect, or where
volatile combustible substances are handled.
Corrosive gas can cause corrosion to the heat exchanger, breaks in
plastic parts etc. and combustible gas or steam can cause fire.
Do not use the unit where water splashes may occur, for ex-
ample 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 and use the system close to equipment that
generates electromagnetic fields or high frequency harmonics.
Equipment such as inverters, standby sets, medical high frequency
equipment and telecommunications equipment can affect the unit
and cause malfunctions and breakdowns. The unit can also affect
medical equipment and telecommunications equipment, so that it
functions incorrectly or not at all.
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 damaged, 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.
If soldering near the unit, ensure that solder residue does not
damage the drip tray.
If solder residue enters the unit during soldering, small holes can
appear in the tray resulting in water leakage. To prevent damage,
keep the indoor unit in its packing or cover it.
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.
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 equip-
ment clean.
Take care when carrying the unit by hand.
If the unit weights more than 20 kg, it must be carried by two
people. Use gloves to minimize the risk of cuts.
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 touch any refrigerant pipes with your hands when
the system is in operation.
During operation the pipes become extremely hot or extremely cold,
depending on the method of operation. This can cause burn injuries
or frost injuries.
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.
Do not control the system with the main switch.
This can cause fire or water leakage. In addition, the fan can start
unexpectedly, which can cause personal injury.
Especially for units intended for R407C
- Do not use other refrigerants that those intended for the unit.
- Do not use charging bottles. These types of bottles change the
composition of the refrigerant, which makes the performance of
the system worse.
- When filling refrigerant, the refrigerant must always leave the
bottle in liquid form.

NIBE™ F2300Chapter 1 | Important information6

Transport and storage
F2300 must be transported and stored vertically.
NOTE
Ensure that the heat pump cannot fall over
during transport.
Assembly
႑Place F2300 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.
႑The concrete foundation or slabs must be positioned
so that the lower edge of the evaporator is at the level
of the average local snow depth, although a minimum
of 300 mm.
႑The F2300 should not be positioned next to sensitive
walls, for example, next to a bedroom.
႑Also ensure that the placement does not inconveni-
ence the neighbours.
႑F2300 must not be placed so that recirculation of the
outdoor air can occur. This causes lower output and
impaired efficiency.
႑Large amounts of condensation water as well as melt
water from defrosting can be produced. Condensation
water must be led off to a drain or similar (see page
8).
႑Care must be exercised so that the heat pump is not
scratched during installation.
LEK LEK
PLQ  PP
Do not place F2300 directly on the lawn or other non
solid surface.
If there is a risk of roof falls, a protective roof or cover
must be erected to protect the heat pump, pipes and
wiring.
7Chapter 2 | Delivery and handlingNIBE™ F2300
2 Delivery and handling

Lift from the street to the set up location
If the base allows, the simplest thing is to use a pallet
truck to move the F2300 to the set up location.
NOTE
The centre of gravity is offset to one side (see
print on the packaging).
LEK
If F2300 must be transported across soft ground, for ex-
ample a lawn, we recommend that a crane that can lift
it to the set up location is used. When the F2300 is lifted
by crane the packaging must be untouched and the load
equally distributed with a boom, as illustrated above.
If a crane cannot be used F2300 can be transported using
an extended sack truck. F2300 must be used on the side
marked "heavy side" and two people are required to get
the F2300 up.
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.
It is not permitted to lift anything other than the machine
feet.
Scrapping
When scrapping, the product is removed in reverse order.
Lift by the bottom panel instead of a pallet!
Condensation water trough
The condensation water trough is used to collect and
lead away condensation water from the heat pump.
NOTE
It is important to the heat pump function that
condensation water is led away and that the
drain for the condensation water run off is not
positioned so that it may cause damage to the
house.
NOTE
Pipe with heating cable for draining the condens-
ation water trough are not included.
NOTE
To ensure this function the accessory KVR 10
should be used.
NOTE
The electrical installation and wiring must be
carried out under the supervision of an author-
ised electrician.
Caution
If none of the recommended alternatives is used
good lead off of condensation water must be
assured.
႑The condensation water (up to 100 litres/day) collec-
ted in the trough should be routed by pipe to an ap-
propriate drain, it is recommended that the shortest
outdoor stretch possible is used.
႑The section of the pipe that can be affected by frost
pipe must be heated by the heating cable to prevent
freezing.
႑Route the pipe downward from F2300.
႑The outlet of the condensation water pipe must be
at a depth that is frost free or alternatively indoors
(with reservation for local ordinances and regulations).
႑Use a water trap for installations where air circulation
may occur in the condensation water pipe.
႑The insulation must be tight against the bottom of
the condensation water trough.

General
Pipe installation must be carried out in accordance with
current norms and directives.
F2300 can only operate up to a return temperature of
about 55 °C and an outgoing temperature of about 65
°C from the heat pump.
F2300 is not equipped with external shut off valves on
the water side; these must be installed to facilitate any
future servicing. The return temperature is limited by the
return line sensor.
Water volumes
When docking with F2300 a minimum available system
volume of at least 20 litres per kW output on the heat
pump is recommended.
NOTE
The pipe work must be flushed before the heat
pump is connected, so that any contaminants
do not damage the components parts.
NOTE
The charge pump must be operational, even if
F2300 is not running, to prevent damage due
to freezing.
The charge pump can also be controlled directly from
F2300, terminal block (X3), which takes the ambient
temperature into consideration. Alternatively, the heat
pump is connected to an intermediate circuit with a heat
exchanger, pump and water with anti-freeze.
