4 Pipe and ventilation connections
General pipe connections
System diagram
Pipe installation must be carried out in accordance with
current norms and directives.
F730 consists of heat pump, water heater, immersion
heater, fan, circulation pump as well as control system.F730 is connected to the ventilation system and
heating medium circuit.
The system requires the radiator circuit to be designed
for a low temperature heating medium. At the lowest
dimensioned outdoor temperature (DOT) the highest
recommended temperatures are 55 °C on the supply
line and 45 °C on the return line.
Overflow water from the evaporator collection tray
and safety valves goes via overflow cup 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.
Maximum boiler and radiator volumes
When the room temperature exhaust air, and in certain
cases outdoor air, 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.
AvluftThe volume
Frånluft
of the pressure expansion vessel (CM1) is 10 litres and it
is pre-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 m, see figure
Extract
air
Avluft
Exhaust
air
Frånluft
H
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
285 litres at the above pre-pressure.

Connecting the climate system
A climate system is a system that regulates indoor
comfort with the help of the control system in F730
and for example radiators, underfloor heating/cooling,
fan convectors etc.
■ When connecting to a system with thermostats on
all radiators, either a bypass valve must be fitted or
some of the thermostats must be removed to ensure
sufficient flow.

Installation alternative
Extra hot water heaters
F730 can be installed in several different ways, some
of which are shown below.
The heat pump should be supplemented with an extra
water heater, if a hot tub or other significant consumer
of hot water is installed.
Further option information is available at www.nibe.eu
and in the respective assembly instructions for the accessories used. See page 50 for a list of the accessories
that can be used with F730.
More information about the options is available at
www.nibe.eu.

Connect F730 so that all exhaust air, except exhaust
air duct air (kitchen fan), passes the evaporator (EP1)
in the heat pump. The lowest ventilation flow must
comply with the applicable national standards. For
optimum heat pump performance, the ventilation flow
should not be less than 21 l/s (75 m³/h) at an exhaust
air temperature of at least 20 °C. When the exhaust air
temperature is lower than 20 °C (for example at startup and when there is no one at home) the minimum
value is31 l/s (110 m³/h).
Ensure that the 440
ventilation openings are not blocked.
Set the ventilation
capacity in the heat pump's menu
615
system (menu 5.1.5).

To obtain the necessary air exchange in every room of
the house, the exhaust air devices must be correctly
positioned and adjusted and the fan in the heat pump
adjusted.

F730 has a very low extract air temperature.
To avoid damaging the product and/or the
building, it is therefore important that the extract air ducts are insulated with diffusionproof material (PE30) along their entire length.

LEK
To prevent fan noise being transferred to the ventilation devices, it may be a good idea to install a silencer
in the duct. This is especially important if there are
ventilation devices in noise sensitive rooms.
Connections must be made via flexible hoses, which
should be installed so that they are easy to replace. The
extract air duct must be provided with diffusion-tight
insulation (PE30) over its entire length. Ensure that the
condensation insulation is sealed at any joints and/or
at lead-in nipples, silencers, roof cowls or similar. Provision must be made for inspection and cleaning of the
duct. Make sure that there are no reductions of crosssectional area in the form of creases, tight bends etc.,
since this will reduce the ventilation capacity. The duct
system must be a minimum of air tightness class B. The
extract air duct must be a maximum of 20 m long with
a maximum of six bends. The ventilation ducts should
be installed in such a way that it is easy to open the
inverter box. The extract air duct should, if possible, be
routed up through the roof. If the duct is to be routed
out through an external wall, avoid having a 90 degree
bend backward, as this can cause noise and poorer
capacity.

General ventilation connection
TIP
If additional condensation insulation (PE30)
dimension Ø 200 is installed on the outside of
the existing exhaust line between the heat
pump and the inner roof, the noise in the installation area is reduced by 1-2 dB(A).
Immediately after installation adjust the ventilation so
that it is set according to the projected value of the
house.
A defective ventilation installation may lead to reduced
installation efficiency and thus poorer operating economy, and may result in moisture damage to the house.
Exhaust air duct /kitchen fan
Exhaust air duct (kitchen fan) must not be connected
to F730.
To prevent food vapour being transferred to F730 the
distance between the kitchen fan and the exhaust air
device must be considered. The distance should not be
less than 1.5 m.
Always use a kitchen fan when cooking.
NOTE
A duct in a masonry chimney stack must not
be used for extract air.

Connections
NOTE
To prevent interference, unscreened communication and/or sensor cables to external connections must not be laid closer than 20 cm
from high voltage cables.
Install the outdoor temperature sensor (BT1) in the
shade on a wall facing north or north-west, so it is unaffected by the morning sun for example.
Connect the sensor to terminal block X6:1 and X6:2 on
the input board (AA3). Use a twin core cable of at least
0.5 mm² cable area.
If a conduit is used it must be sealed to prevent condensation in the sensor capsule.
Power connection
F730 must be installed via an isolator switch with a
minimum breaking gap of 3mm. Minimum cable area
must be sized according to the fuse rating used. The
enclosed cable (length approx. 2 m) for incoming supply electricity is connected to terminal block X1 on the
immersion heater board (AA1). The connection cable
can be found on the reverse of F730 (see dimensions

Room sensor
F730 is supplied with a room sensor enclosed (BT50).
The room sensor has up to three functions:
1. Show current room temperature in F730's display.
2. Option of changing the room temperature in °C.
3. Makes it possible to change/stabilise the room
temperature.
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.
The heat pump operates without the sensor, but if one
wishes to read off the accommodation's indoor temperature in F730's display, the sensor must be installed.
Connect the room sensor to X6:3 and X6:4 on the input
board (AA3).
If the sensor is to be used to change the room temperature in °C and/or to change/stabilise the room temperature, the sensor must be activated in menu 1.9.4.
If the room sensor is used in a room with underfloor
heating, it should only have an indicatory function, not
control of the room temperature.

The table displays the maximum phase current for the
relevant electrical step for the heat pump.
In addition to this, there is the current for the compressor, which, depending on the operating conditions,
can amount to 12A on L2.
If the current sensors are connected, the heat pump
monitors the phase currents and allocates the electrical
steps automatically to the least loaded phase.
Output locking
F730 follows applicable building regulations (BBR). This
means that the maximum power output (maximum

Optional connections
NIBE Uplink™
Load monitor
Connect the network connected cable (straight, Cat.5e
UTP) with RJ45-contact (male) to RJ45 contact (female)
on the rear of the heat pump.
When many electrical appliances 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 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 electrical distribution unit. The
multi-core cable between the enclosure and the heat
pump must have a cable area of at least 0.5 mm².
Connect the cable to the input board (AA3) on terminal
X4:1-4 block - where X4:1 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.

Venting the climate system
Preparations
1. Check that the switch (SF1) is in position "
".
Caution
Check the miniature circuit-breaker (FA1) in
the heat pump. It may have tripped during
transportation.
1. Turn off the power supply to the heat pump.
2. Vent the heat pump via the vent valves (QM20),
(QM22), (QM24), (QM26) and the rest of the climate system via the relevant vent valves.
3. Keep topping up and venting until all air has been
removed and the pressure is correct.
NOTE
The vent hoses from the container must be
drained of water before air can be released.
This means that the system is not necessarily
vented despite the flow of water when the
vent valves (QM20), (QM22), (QM24), (QM26)
are opened.
Filling and venting
Filling the hot water heater
1. Open a hot water tap in the house.
2. Open the filling valve (QM10). This valve should
then be fully open during operations.
3. When water comes out of the hot water tap, the
hot water heater is full and the tap can be closed.
QM11
FL1
QM24
FL2
Filling the climate system
1. Open the vent valves (QM20), (QM22), (QM24) and
(QM26).
2. Open the filler valves (QM11) and (QM13). The
boiler unit and the rest of the climate system are
filled with water.
3. When the water exiting the bleed valves (QM20),
(QM22), (QM24) and (QM26) is no longer mixed
with air, close the valves. After a while, the pressure
rises on the pressure gauge(BP5). When the pressure reaches 2.5 bar (0.25 MPa) the safety valve
starts to (FL2) release water. Close the filling
valve(s).
4. Reduce the boiler pressure to the normal working
range (approx. 1 bar) by opening the vent valves
(QM20), (QM22), (QM24) and (QM26) or safety
valve (FL2).
5. Check that there is water in the overflow cup
(WM1).
6. Start the heat pump and allow it to run in both
heating and hot water modes.
7. Vent the climate system (see section "Venting the

Caution
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.
* A low-temperature radiator system refers to a system where
the supply temperature needs to be 55 °C on the coldest day.
** Under floor heating can be dimensioned very differently. The
example above refers to a system where the supply temperature
must be approx 35 – 40 °C resp. 45 – 50 °C on the coldest day.
The lower values in the northern part of Sweden are
due to the fact that buildings are built and insulated
in a different way to those in the south of the country
and the climate systems are dimensioned in a different
way.

9 Service
NOTE
Draining the climate system
Servicing and maintenance should only be
carried out by persons with the necessary expertise.
In order to carry out service on the climate system, it
may be easier to drain the system first.
When replacing components on F730 only
replacement parts from NIBE may be used.
Maintenance
Inform the user of necessary maintenance action.
Cleaning the overflow cup/floor drain
Regularly check that the overflow cup and any floor
drains are not blocked; water must be able to run
through freely. Clean, if necessary.
NOTE
If the overflow cup or floor drain is blocked,
water can run over onto the floor of the installation area. To prevent damage to the building
the floor coating must be considered. A waterproof floor or floor membrane is recommended.
NOTE
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) or the drain valve's
(XL10) outlet.
1. Open the safety valve (FL2) or the drain valve
(XL10).
2. Set the vent valves for the climate system (QM20),
(QM22), (QM24), (QM26) in the open position for
air supply.
NOTE
The heat pump should not, after draining, be
exposed to risk of freezing because a certain
of water remains in the coil.
Service actions
Emergency mode
Emergency mode is used in event of operational interference and in conjunction with service.
Emergency mode is activated by setting switch (SF1)
in mode " ". This means that:
■ The status lamp illuminates yellow.
■ The display is not lit and the control computer is not
connected.
■ The temperature at the immersion heater is con-
trolled by the thermostat (FD1-BT30). It can be set
either to 35 or 45 °C.
■ The compressor is off and only the fan, heating me-
dium pump and the electric additional heat are active. The additional heat power in emergency mode
is set in the immersion heater card (AA1). See page
23 for instructions.
Draining the water heater
The water heater can be drained via the safety valve
(FL1) or via the overflow cup (WM1).
1. Disconnect the overflow pipe from the safety valve
(FL1) and connect a hose to a draining pump instead. If a draining pump is not available, the water
can be released into the overflow cup (WM1).
2. Open the safety valve (FL1).
3. Open a hot water tap to let air into the system. If
this is not sufficient, detach the pipe connection
(XL4) on the hot water side and ensure that air is
entering.

10 Disturbances in comfort
In most cases, the heat pump notes operational interference (operational interference can lead to disturbance in comfort) and indicates this with alarms and
shows action instructions in the display.
Info-menu
All the heat pump measurement values are gathered
under menu 3.1 in the heat pump menu system.
Looking through the values in this menu can often
simplify finding the source of the fault. See help menu
or user manual for more information about menu 3.1.
Manage alarm
Low pressure alarm
Caution
Selecting "aid mode” is not the same as correcting the problem that caused the alarm. The
status lamp will therefore continue to be red.
Troubleshooting
If the operational interference is not shown in the display the following tips can be used:
Basic actions
Start by checking the following possible fault sources:
■ The switch's (SF1) position.
■ Group and main fuses of the accommodation.
■ The property's earth circuit breaker.
alarm
info / action
reset alarm
aid mode
■ The heat pump's miniature circuit breaker (FA1).
■ The heat pump's temperature limiter (FD1).
Low hot water temperature or a lack of hot
water
■ Closed or choked filling valve (QM10) for the water
In the event of an alarm, some kind of malfunction has
occurred, which is indicated by the status lamp changing from green continuously to red continuously. In
addition, an alarm bell appears in the information
window.
Alarm
In the event of an alarm with a red status lamp a malfunction has occurred that the heat pump cannot
remedy itself. In the display, by turning the control knob
and pressing the OK button, you can see the type of
alarm it is and reset it. You can also choose to set the
heat pump to aid mode.
info / action Here you can read what the alarm means
and receive tips on what you can do to correct the
problem that caused the alarm.
reset alarm In most cases it is enough to select ”reset
alarm” to correct the problem that caused the alarm.
If a green light illuminates after selecting "reset alarm"
the alarm has been remedied. If a red light is still visible
and a menu called ”alarm” is visible in the display, the
problem that caused the alarm remains. If the alarm
disappears and then returns, see the section
"Troubleshooting".
aid mode ”aid mode” is a type of emergency mode.
This means that the heat pump produces heat and/or
hot water despite there being some kind of problem.
This can mean that the heat pump's compressor is not
running. In this case the immersion heater produces
heat and/or hot water.
NOTE
To select aid mode an alarm action must be
selected in the menu 5.1.4.
