This symbol indicates danger to machine or
person.
Caution
This symbol indicates important information
about what you should observe when maintaining your installation.
TIP
This symbol indicates tips on how to facilitate
using the product.
Marking
F1345 is CE marked and fulfils IP21.
The CE marking means that NIBE ensures that the product
meets all regulations that are placed on it based on relevant EU directives. The CE mark is obligatory for most
products sold in the EU, regardless where they are made.
IP21 means that the product can be touched by hand,
that objects with a diameter larger than or equivalent to
12.5 mm cannot penetrate and cause damage and that
the product is protected against vertically falling drops.
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 refrigerant 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 refrigerant 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.
Use types of pipe and tools stated for this type of refrigerant.
Using existing parts for other refrigerants can cause breakdowns
and serious accidents due to process circuit bursts.
Switch off the compressor before opening/breaching the refrigerant 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 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
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.

Chapter 1 | Important information
NIBE™ F1345
Use main switch with sufficient breaking capacity.
If the switch does not have sufficient breaking capacity, malfunctions
and fire can occur.
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.
Serial number
The serial number can be found at the bottom right of
the front cover and in the info menu (menu 3.1).
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 nitrous 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 for specialist purposes such as for storing
food, cooling precision instruments, freeze-conservation of
animals, plants or art.
This can damage the items.

Caution
Always give the product's serial number (14 digits) when reporting a fault.
Country specific information
Installer manual
This installer manual must be left with the customer.
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.
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 R410A
- Only use R410A refrigerant. R410A means that the pressure is
about 1.6 times as high as conventional refrigerants.
- The filling connections on units with R410A are different sizes, to
prevent the system being filled with the incorrect refrigerant by
mistake.
- 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.

2 Delivery and handling
Transport
F1345 should be transported and stored vertically in a
dry place. When being moved into a building, the heat
pump may be tilted back 45 °. NOTE! The heat pump is
top heavy.
If the cooling modules are pulled out and transported
upright, F1345 can be transported on its back.
1
NOTE
Ensure that the heat pump cannot fall over
during transport.
2
TIP
The side panels can be removed for easier installation in the building.
LEK
0
R
If F1345 needs to be transported across soft ground, such
as a lawn, we recommend that a crane is used that can
lift the unit to the installation location. When F1345 is
raised using a crane, distribute the load according to the
instructions on the packaging.
If a crane cannot be used F1345 can be transported on
a sack truck. F1345 must be taken from its heaviest side
(see printed material on packaging for where the centre
of gravity is) and two people are required to lift F1345.
R
0
Lift from the pallet to final positioning
Before lifting, remove the packaging and the load anchor
to the pallet as well as front and side panels.
Before lifting, the heat pump must be separated by
pulling the cooling modules out from the cabinet. See
the service chapter in the operating manual for instructions about the separation.
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 F1345 to the set up location.
NOTE
The centre of gravity is offset to one side (see
print on the packaging).
Carry the heat pump by the upper cooling module's slide
rails, use gloves.
NOTE
The heat pump must not be moved when only
the lower cooling module has been pulled out.
If the heat pump is not secured in position the
upper cooling module must always be removed
before the lower one can be pulled out.
Scrapping
For scrapping, remove the product in reverse order.

4 Pipe connections
General
Pipe installation must be carried out in accordance with
current norms and directives. F1345 can operate with a
return temperature of up to 58 °C and an outgoing
temperature from the heat pump of 65 °C.
F1345 is not equipped with internal shut off valves; these
must be installed to facilitate any future servicing.
NOTE
The pipe system needs to be flushed out before
the heat pump is connected so that debris cannot damage component parts.
NOTE
System diagram
F1345 consists of two heat pump modules, circulation
pumps and control system with possibility of additional
heat. F1345 is connected to the brine and heating medium circuits.
In the heat pump evaporator, the brine (water mixed with
anti-freeze, glycol or ethanol) releases its energy to the
refrigerant, which is vaporised in order to be compressed
in the compressor. The refrigerant, of which the temperature has now been raised, is passed to the condenser
where it gives off its energy to the heating medium circuit
and, if necessary, to any docked water heater. If there is
a greater need for heating/hot water than the compressors can provide it is possible is to connect an external
immersion heater.
Do not solder directly on the heat pump pipes,
because of internal sensors.
Compression ring coupling alternatively pressure
connection should be used.

harm other equipment.
Caution
When necessary you should install venting valves
in the brine system.
Applies to PEM hose 40x2.4 PN 6.3.
These are rough example values. At installation the correct
calculations must be made according to local conditions.
Caution
The length of the collector hose varies depending on the rock/soil conditions, climate zone and
on the climate system (radiators or underfloor
heating).
Max length per coil for the collector should not exceed
500 m.
The collectors must always be connected in parallel with
the possibility of adjusting the flow for the relevant coil.
For surface soil heat, the hose should be buried at a depth
determined by local conditions and the distance between
the hoses should be at least 1 metre.
For several bore holes, the distance between the holes
must be determined according to local conditions.
႑ Mark the brine system with the antifreeze that is used.
႑ Install the supplied safety valve at the expansion vessel
as illustrated in the outline diagram. The entire length
of the overflow water pipe from the safety valves must
be inclined to prevent water pockets and must also be
frost-free.
႑ Install shut off valves as close to the heat pump as
possible so that the flow to individual cooling modules
can be shut off. Extra safety valves between the particle
filter and shut off valves (according the outline diagram)
are required.
႑ Fit the supplied particle filter on the incoming pipe.
႑ Fit the supplied non-return valves on the outgoing pipe.
In the case of connection to an open groundwater system,
an intermediate frost-protected circuit must be provided,
because of the risk of dirt and freezing in the evaporator.
This requires an extra heat exchanger.
P
Ensure the collector hose rises constantly towards the
heat pump to avoid air pockets. If this is not possible,
airvents should be used.
As the temperature of brine system can fall below 0 °C
it must be protected against freezing down to -15 °C. 1
litre of ready mixed brine per meter of collector hose
(applies when using PEM-hose 40x 2.4 PN 6.3) is used as
a guide value when making the volume calculation.
Caution
Because the temperature of the brine system
varies depending on the heat source, the menu
5.1.7 "br pmp al set." must be set to the suitable value.

A climate system is a system that regulates indoor comfort
with the help of the control system in F1345 and for example radiators, underfloor heating/cooling, fan convectors etc.
႑ The pipe connections are on the rear of the heat pump.
႑ Install the necessary safety equipment and shut off
valves (installed as close to the heat pump as possible
so that the flow to individual cooling modules can be
shut off).
႑ Fit the supplied particle filter on the incoming pipe.
႑ The safety valve must have a maximum 0.6 MPa (6.0
bar) opening pressure and be installed on the heating
medium return. The entire length of the overflow water
pipe from the safety valves must be inclined to prevent
water pockets and must also be frost-free.
႑ When connecting to a system with thermostats on all
radiators, a relief valve must be fitted, or some of the
thermostats must be removed to ensure sufficient flow.
႑ Fit the supplied non-return valves on the outgoing pipe.
႑ Any docked hot water heater must be fitted with ne-
cessary set of valves.
႑ The mixing valve must be installed if the setting is
changed so that the temperature can exceed 60 °C.
႑ The setting for hot water is made in menu 5.1.1.
႑ The safety valve must have a maximum opening pres-
sure in accordance with the water heater manual and
be installed on the incoming domestic water line. The
entire length of the overflow water pipe from the safety
valves must be inclined to prevent water pockets and
must also be frost-free.
Caution
Hot water production is activated in menu 5.2
or in the start guide.

Load monitor
Room sensor
When many power consumers are connected in the
property at the same time as the electric additional heat
is operating, there is a risk of the property's main fuse
tripping. The heat pump has integrated load monitors
that control the electrical steps for the electrical additional
heat by disconnecting step by step in event of overload
in a phase. Reconnection occurs when other current
consumption is reduced.
F1345 can be supplemented with a room sensor (BT50).
The room temperature sensor has up to three functions:
1. Show current room temperature in the heat pump's
display.
2. Option of changing the room temperature in °C.
3. Makes it possible to change/stabilise the room temperature.
Connecting current sensors
Install the sensor in a neutral position where the set
temperature is required. A suitable location is on a free
inner wall in a hall approx. 1.5 m above the floor. It is
important that the sensor is not obstructed from measuring the correct room temperature by being located, for
example, in a recess, between shelves, behind a curtain,
above or close to a heat source, in a draft from an external door or in direct sunlight. Closed radiator thermostats
can also cause problems.
A current sensor (BE1 - BE3) should be installed on each
incoming phase conductor in to the distribution box to
measure the current. The distribution box is an appropriate installation point.
Connect the current sensors to a multi-core cable in an
enclosure next to the distribution box. Use a multi-core
cable of at least 0.5 mm2 from the enclosure to the heat
pump.
Connect the cable to terminal X6:10 to 12 and X6:GND
where X6:GND is the common terminal block for the
three current sensors.
The size of the property’s main fuse is set in menu 5.1.12.

Reversing valves
External connection options
F1345 can be supplemented with an external reversing
valve (QN10) for hot water control (see page 37 for accessory).
On terminal block (X6), F1345 has software controlled
inputs and outputs for connection of external contact
function. This means that an external contact function
can be connected to one of three special connections
where the function for connection must be decided in
the heat pump software.
Connect the external reversing valve (QN10) as illustrated
to terminal block X2:10 (N), X2:12 (operation) and X2:13
(L).
With several heat pumps connected as master/slave,
connect the reversing valve electrically to a suitable heat
pump. The reversing valve is controlled by the master
heat pump regardless which heat pump it is connected
to.
If an external contact function is connected to
F1345, the function for use input or output must
be selected in menu 5.4.
Selectable inputs on the input card for these functions
are AUX1 (X6:17), AUX2 (X6:18) and AUX3 (X6:19).
Connect ground to terminal block X6:GND. Selectable
outputs are terminal block X5.
