Chapter 1 | Important information
NIBE™ F470
Before work is started on systems that contains combustible refrigerants, safety checks must be performed to
ensure that the ignition risk is kept to a minimum.
႑
All markings of equipment are visible and clear.
Markings, signs and similar that are not clear must
be replaced.
The work must be carried out in a controlled way to
minimise the risk of contact with combustible gas or liquid
during the work.
႑
Refrigerant pipes and components are positioned in
such a way that it is not likely that they be subjected
to substances that can corrode components containing refrigerant, if these components are not made of
material that is resistant against corrosion, or not appropriately protected against such corrosion.
All maintenance staff and those who work in close proximity to the product must be instructed which type of
work is to be carried out. Avoid carrying out work in enclosed spaces. The area surrounding the worksite must
be cordoned off. Ensure that the area is made safe by
removing combustible material.
Check whether there is refrigerant in the area using a
suitable refrigerant detector prior to and during work, to
notify the service technician whether there is a possible
flammable atmosphere or not. Ensure that the refrigerant
detector is suitable for combustible refrigerant, i.e. does
not generate sparks or cause ignition in any other way.
Repair and maintenance of electrical components must
include initial safety checks and procedures for component inspection. In the event of a fault, which can cause
a safety risk, do not supply any power to the circuit until
the fault has been rectified. If the fault cannot be rectified
immediately, and operation must continue, an adequate
temporary solution must be implemented. This must be
reported to the equipment owner, so that all parties have
been informed.
If hot work is carried out on the heat pump, a powder
or carbon dioxide fire extinguisher must be to hand.
The following checks must be carried out at the initial
safety checks.
Those who carry out work with refrigerant system connections, including exposing pipes that contain or have
contained combustible refrigerant, may not use potential
ignition sources in such a way that that can lead to risks
of fire or explosions.
All potential ignition sources, including cigarette smoking,
should be kept at a safe distance from the service work
area where combustible refrigerant can leak out. Before
carrying out work, the area surrounding the equipment
must be checked to ensure that there are no ignition
risks. "No smoking" signs must be displayed.
Ensure that the work is carried out outdoors or that the
work area is ventilated before the system is opened and
before any hot work is carried out. The area must be
ventilated whilst the work is being carried out. There must
be ventilation around any refrigerant that comes out,
which should be routed outdoors.
If electrical components are replaced, the replacement
parts must be fit for purpose and have the correct technical specifications. Always follow the manufacturer's
guidelines regarding maintenance and servicing. Contact
the manufacturer's technical department in the event of
any doubts.
The following checks must be carried out for installations
that use combustible refrigerants.
႑
The filling quantity is appropriate for the size of the
space where the parts that contain refrigerant are installed.
႑
Ventilation equipment and outlet work correctly and
without obstructions.
႑
If an indirect refrigerant circuit is used, check whether
the secondary circuit contains refrigerant.
NIBE™ F470
႑
That the capacitors are discharged. Discharging must
be done safely, to prevent the risk of sparking.
႑
That no powered electrical components or live cables
are exposed when filling or collecting refrigerant or
when the system is flushed.
႑
That the system is continually grounded.
Removal and draining
When a cooling circuit is opened for repairs – or for another reason– work must be carried out in a conventional
manner. Due to the risk of fire it is important that best
practice is applied. Follow the procedure below.
1.
2.
3.
4.
5.
Drain the refrigerant.
Flush the circuit with inert gas.
Drain the circuit.
Flush again with inert gas.
Open the circuit by cutting or burning.
Collect the refrigerant in the intended container. Flush
the system with oxygen-free nitrogen to make the device
safe. This process may need to be repeated several times.
Compressed air and oxygen may not be used.
Flush the system by breaking the vacuum with oxygenfree nitrogen, and filling the system to working pressure,
relieving the pressure to atmospheric pressure and finally
pumping to vacuum. Repeat the process until no refrigerant remains in the system. After the final filling of oxygenfree nitrogen, relieve the pressure in the system to atmospheric pressure, so that work can be carried out. This
type of flushing must be carried out if hot work is to be
performed on the pipe system.
Chapter 1 | Important information
3
Ensure that the vacuum pump's outlet is not near to ignition sources and that there is satisfactory ventilation by
the outlet.
oil and refrigerant must be taken, if analyses are required
before collected refrigerant can be reused. There must
be a power supply when this task is started.
Filling
1. Familiarise yourself with the equipment and its use.
2. Isolate the system electrically.
3. Before starting the procedure, ensure that:
In addition to the conventional filling procedures, the
following actions must be taken.
Ensure that different refrigerants are not mixed when
filling equipment is used. Hoses and lines must be as
short as possible to minimise the enclosed refrigerant
volume.
necessary equipment for mechanical handling of the
refrigerant container is available
႑
Containers must be stored upright.
႑
Ensure that the cooling system is grounded before
the system is filled with refrigerant.
the collection process is continuously supervised by
an authorised person
႑
Mark the system once filling is complete (if not already
marked).
႑
Take extra care not to overfill the cooling system.
႑
Before refilling the system, pressure test it with oxygenfree nitrogen. Leak test the system after filling but before
using the system. Perform an additional leak test before
leaving the installation.
the collection equipment and containers meet appropriate standards.
4. Pump the refrigerant system to vacuum, if possible.
5. If it is not possible to pump to vacuum, manufacture
a branch, so that the refrigerant can be retrieved
from different parts of the system.
6. Check that the refrigerant container is on the scales
before starting to collect.
Leak testing
7. Start the collection device and collect according to
The following leak detection methods are deemed acceptable for systems containing flammable refrigerants.
8. Do not overfill the containers (max 80 % (volume)
Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need re-calibration. (Detection equipment
shall be calibrated in a refrigerant-free area.) Ensure that
the detector is not a potential source of ignition and is
suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed
and the appropriate percentage of gas (25 % maximum)
is confirmed.
Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine
shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work.
If a leak is suspected, all naked flames shall be removed/extinguished.
If a leakage of refrigerant is found which requires brazing,
all of the refrigerant shall be recovered from the system,
or isolated (by means of shut off valves) in a part of the
system remote from the leak. Oxygen free nitrogen (OFN)
shall then be purged through the system both before and
during the brazing process.
Decommissioning
Before performing this procedure, the technician must
be familiar with the equipment and all its component
parts. Good practice prescribes that all refrigerant is collected safely. Before the work is carried out, samples of

9. Do not exceed the containers' maximum permitted
working pressure – not even temporarily.
10. When the containers have been filled correctly and
the process is complete, close all shut-off valves in
the equipment and remove and containers and
equipment from the installation immediately.
11. The collected refrigerant must not be filled in any
other system before being cleaned and checked.
Marking
The equipment must be marked stating that it has been
taken out of operation and drained of refrigerant. The
marking must be dated and signed. Check that the
equipment is marked indicating that it contains combustible refrigerant.
Collection
Best practice prescribes that all refrigerant is collected
safely when the refrigerant is drained from a system,
either for servicing or for decommissioning.
The refrigerant must only be collected in suitable refrigerant containers. Ensure that the required number of containers, that can hold the entire volume of the system,
are available. All containers that are to be used must be
intended for the collection of the refrigerant and marked
for this refrigerant (especially designed for the collection
of refrigerant). The containers must have the correctly
functioning relief valves and shut-off valves. Empty collecNIBE™ F470
tion containers must be drained and, if possible, chilled
before collection.
The collection equipment must function correctly and
instructions for the equipment must be to hand. The
equipment must be suitable for the collection of combustible refrigerant.
Serial number
The serial number can be found at the bottom right of
the front cover and in the info menu (menu 3.1).
Fully functioning and calibrated scales must also be to
hand.
Hoses must be in good condition and be equipped with
leak proof quick-couplings. Before using the collecting
machine, check that it works correctly and has been well
maintained, and that corresponding electrical components
are sealed, to prevent ignition if any refrigerant should
come out. Contact the manufacturer in the event of any
doubts.
Return the collected refrigerant to the refrigerant supplier
in the correct collection container and with the relevant
Waste Transfer Note. Do not mix refrigerants in collection
devices or containers.

4 Pipe and ventilation connections
General pipe connections
Pipe installation must be carried out in accordance with
current norms and directives.
The system requires a low-temperature design of the radiator circuit. At lowest dimensioned outdoor temperature
(DUT) the highest recommended temperatures are 55 °C
on the flow line and 45 °C on the return line.
Overflow water from the evaporator collection tray and
safety valves goes via non-pressurised collecting pipes to
a drain so that hot water splashes cannot cause injury.
The entire length of the overflow water pipe must be inclined to prevent water pockets and must also be frost
proof.
NOTE
The pipe system needs to be flushed out before
the heat pump is connected so that any debris
cannot damage component parts.
System diagram
F470 consists of a heat pump, water heater, immersion
heater, circulation pump and control system. F470 is
connected to ventilation system and heating medium
circuits.
When the exhaust air at room temperature passes
through the evaporator, the refrigerant evaporates because of its low boiling point. In this way the energy in
the room air is transferred to the refrigerant.
The refrigerant is then compressed in a compressor,
causing the temperature to rise considerably.
The warm refrigerant is led to the condenser. Here the
refrigerant gives off its energy to the boiler water,
whereupon the refrigerant changes state from gas to liquid.
The refrigerant then goes via filters to the expansion valve,
where the pressure and temperature are reduced.
The refrigerant has now completed its circulation and
returns to the evaporator.
The volume of the pressure expansion vessel (CM1) is 10 litres and it
is pressurised as standard to 0.5 bar
((5 mvp). As a result, the maximum
permitted height "H" between the
vessel and the highest radiator is 5
metres; see figure.
H
Maximum boiler and radiator volumes
If the standard initial pressure in the
pressure vessel is not high enough
it can be increased by adding air via
the valve in the expansion vessel.
The initial pressure of the expansion
vessel must be stated in the inspection document. Any
change in the initial pressure affects the ability of the
expansion vessel to handle the expansion of the water.
The maximum system volume excluding the boiler is 219
litres at the above pre-pressure.

Connecting the climate system
When connecting to a system with thermostats on all
radiators/underfloor heating coils, a relief valve must be
fitted, or a thermostat must be removed to ensure sufficient flow.
NIBE™ F470
Supply air battery
The supply air coil is connected in parallel with the radiator circuit and heats the house’s supply air. The water flow
through the supply air battery is set by means of a trim
valve (RN1). The supply air temperature must be approximately the same as the indoor temperature, preferably
a few degrees lower.
TIP
If possible, choose a cold day to adjust the trim
valve.
Connecting hot water circulation
To reduce the risk of bacterial growth in systems with
hot water circulation, the temperature of the circulating
water should not fall below 50 °C. There should not be
any non-circulatory hot water pipes. Adjust the hot water
system so that the temperature does not fall below 50
°C at the ends of the system.
The circulation pump for hot water circulation can be
controlled by the heat pump. The HWC return can be
connected to a freestanding water heater.
Installation alternative
F470 can be connected in several different ways, some
of which are shown below.
Further option information is available at www.nibe.eu
and in the respective assembly instructions for the accessories used. See page 66 for a list of the accessories
that can be used with F470.
Extra hot water heaters
The heat pump should be supplemented with an electric
water heater, if a hot tub or other significant consumer
of hot water is installed.
Two or more climate systems
When more than one climate system is to be heated, the
following connection can be used.
The ECS 40/ECS 41. accessory is required for this connection.
NIBE™ F470
Chapter 4 | Pipe and ventilation connections

General ventilation connection
Ventilation flow
Ventilation installation must be carried out in accordance
with current norms and directives.
Connect F470 so that all exhaust air except exhaust air
duct air (kitchen fan) passes the evaporator (EP1) in the
heat pump. The lowest ventilation flow should be according to current national standards. For optimum heat pump
performance the ventilation flow should not be less than
31 l/s (110 m³/h). The supply air flow should be lower
than the exhaust air flow to prevent over pressure in the
house.
To prevent fan noise being transferred to air devices
should a silencer be installed in the duct.
Connections must be made via flexible hoses, which must
be installed so that they are easy to replace. The extract
air and outdoor air ducts are to be insulated using diffusion-proof material along their entire lengths. Provision
must be made for inspection and cleaning of the duct.
Make sure that there are no reductions of cross-sectional
area in the form of creases, tight bends etc, since this will
reduce the ventilation capacity. The air duct system must
be a minimum of air tightness class B.
The heat pump’s installation area should be ventilated
with at least 5 l/s (18 m³/h). The installation area must
have a volume of at least 8 m³.
Ensure that the ventilation openings are not blocked. Set
the ventilation capacity in the heat pump's menu system
(menu 5.1.5).
The exhaust air duct must be a maximum of 20 m long
and contain a maximum of six bends.
Adjusting ventilation
Because the heat pump contains a flammable refrigerant
in the form of propane (R290), the air ducting system
must be grounded. This is done by making a sound electrical connection to the four ventilation ducts using the
four ground cables supplied. The cables must then be
connected to the ground studs on top of the top cover.
To obtain the necessary air exchange in every room of
the house, the exhaust air device and the supply air device
must be correctly positioned and adjusted and the fans
in the heat pump adjusted.
The factory setting for the ventilation on the heat pump
is 50% and you should therefore adjust the ventilation
immediately after installation so that it is set according
to the projected value for the house.
Exhaust air duct
Exhaust air duct (kitchen fan) must not be connected to
F470.
A defective ventilation installation may lead to reduced
installation efficiency and thus poorer operating economy,
and may result in moisture damage to the house.
NOTE
A duct in a masonry chimney stack must not be
used for extract air.

Optional connections
Load monitor
When many power consumers are connected in the
property at the same time as the electric addition 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 addition by redistributing the power between the different phases or disengaging in event of overload in a phase. Reconnection
occurs when other current consumption is reduced.
Connecting current sensors
A current sensor 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 the input card (AA3) on terminal
block X4:1-4 where X4:1 is the common terminal block
for the three current sensors.

Example: If the supply air flow rate is set to 150 m³/h and
DUT is -20 °C a setting is obtained, at a pump pressure
(= pressure drop coil circuit ) of 3.3 mvp (33 kPa), of 2.8
on the trim valve.
This means the trim valve should be opened 2.8 turns
from the closed position. At the same time it can be read
that the coil supplies the supply air with approximately

Caution
Menu 1.3.1 - heating
An increase in the room temperature can be
slowed by the thermostats for the radiators or
under floor heating. Therefore, open the thermostat valves fully, except in those rooms where a
cooler temperature is required, e.g. bedrooms.
Increases or decreases in the accommodation temperature
can be scheduled here for up to three time periods per
day. If a room sensor is installed and activated the desired
room temperature (°C) is set during the time period.
Without an activated room sensor the desired change is
set (of setting in menu 1.1). A one degree change in room
temperature requires one increment for underfloor
heating and approximately two to three increments for
the radiator system.
TIP
Wait 24 hours before making a new setting, so
that the room temperature has time to stabilise.
If it is cold outdoors and the room temperature
is too low, increase the curve slope in menu
1.9.1 by one increment.
If two settings conflict with each other a red exclamation

pump’s control computer determines the temperature of
the water to the heating system, flow line temperature,
and therefore the indoor temperature. You can select
heating curve and read off how the flow line temperature
changes at different outdoor temperatures here.
Curve coefficient
An offset of the heating curve means that the supply
temperature changes as much for all the outdoor temperatures, e.g. that a curve offset of +2 steps increases the
supply temperature by 5 °C at all outdoor temperatures.

Because the flow line temperature cannot be calculated
higher than the set maximum value or lower than the set
minimum value the heating curve flattens out at these
temperatures.
Caution
The optimum slope depends on the climate conditions
in your location, if the house has radiators or under floor
heating and how well insulated the house is.
Underfloor heating systems are normally max
flow line temperature set between 35 and 45
°C.
The heating curve is set when the heating installation is
installed, but may need adjusting later. Thereafter the
heating curve should not need further adjustment.
Check the max temperature for your floor with
your installer/floor supplier.

If a room sensor is installed and activated the desired
room temperature (°C) is set during the time period. This
setting applies to all climate systems with room sensors.
If a room sensor is not activated, the desired offset of the
heat curve is set. This setting applies to all climate systems
without room sensors. A one degree change in room
temperature requires one increment for under floor
heating and approximately two to three increments for
the radiator system.
Vacation scheduling starts at 00:00 on the start date and
stops at 23:59 on the stop date.

The display is not lit and the control computer is not
connected.
႑
The temperature in the heat pump boiler section is
controlled by a fixed thermostat (BT30) at 63 °C.
႑
The compressor is off and only the fans, heating medium pump and the electrical addition are active. The
electrical addition power in emergency mode is set in
the immersion heater card (AA1). See page 23 for
instructions.
႑
The automatic heating control system is not operational, so manual shunt operation is required. This is done
by turning the adjustment screw on the shunt motor
(MA1) to "manual mode" and then turning the shunt
knob to the desired position.
There may be some hot water when draining
the heating medium side/climate system. There
is a risk of scalding.
The hot water can be tapped through safety valve (FL2)
via the overflow cup (WM1) or through a hose that is
connected to the safety valve's (FL2) outlet.
1. Open the safety valve (FL2).
2. Set the vent valve for the climate system (QM20) in
the open position for air supply.
