F750 – An excellent choice
F750 is part of a new generation of heat pumps, which have been introduced to supply your home with inexpensive and environmentally friendly
heating. Heat production is safe and economical with integrated hot water
heater, immersion heater, circulation pump and control system.
The heat pump can be connected to an optional low temperature heat
distribution system. e.g. radiators, convectors or under floor heating. It is
also prepared for connection to several different products and accessories,
e.g. extra water heater and climate systems with different temperatures.
F750 is equipped with a control computer for good comfort, good economy
and safe operation. Clear information about status, operation time and
all temperatures in the heat pump are shown on the large and easy to
read display. This means, for example, that external unit thermometers
are not necessary.
Excellent properties for F750:
႑ Integrated water heater
There is a water heater integrated in the heat pump, which is insulated
with environmentally friendly cellular plastic for minimal heat loss.
႑ Buffer vessel
There is a buffer vessel integrated in the heat pump that equalises the
temperature of the water that is sent out in the climate system.
႑ Scheduling the indoor comfort and hot water
Heating and hot water as well as ventilation, can be scheduled for each
day of the week or for longer periods (vacation).
႑ Display with user instructions
The heat pump has a large display with easy-to-understand menus that
facilitate setting a comfortable climate.
႑ Simple troubleshooting
In the event of a fault, the heat pump display shows what happened
and the actions to be taken.

NIBE™ F750
Heat pump function
A exhaust air heat pump uses the heat that is in the building's ventilation
air to heat up the accommodation. The conversion of the ventilation air's
energy to accommodation heating occurs in three different circuits. From
the outgoing ventilation air (1) , free heating energy is retrieved from the
accommodation 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.
A
B
C
D
E
F
G
H
Ventilation air
The hot air is transferred from the rooms to the heat pump via the house
ventilation system.
The fan then routes the air to the heat pump’s evaporator. Here, the air
releases the heating energy and the air's temperature drops significantly.
The cold air is then blown out of the house.
Refrigerant circuit
A liquid, a refrigerant, circulates in a closed system in the heat pump which
also passes the evaporator. The refrigerant has a very low boiling point.
In the evaporator the refrigerant receives the heat energy from the ventilation air and starts to boil.
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.
100 °C.
From the compressor, gas is forced into a heat exchanger, condenser,
where it releases heat energy to the heat pump boiler section, whereupon
the gas is cooled and condenses to a liquid form again.
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.
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).
The heating medium circulates in a closed system and transports the heated
water's heat energy to the heat pump's integrated hot water heater and
the radiators/heating coils of the house.
Buffer vessel

The heating medium passes the heat pump's integrated buffer vessel
whereupon the temperature is equalised. It is then transported to the
heating system of the house.

K
Cleaning the ventilation devices
The building’s ventilation devices should be
cleaned regularly with, for example, a small
brush to maintain the correct ventilation.
The device settings must not be changed.
NOTE
If you take down more than one ventilation
device for cleaning, do not mix them up.
Chapter 2 | The heat pump – the heart of the house
NIBE™ F750
23
Cleaning the air filter
Clean the F750's air filter regularly, how often depends on the amount of
dust in the ventilation air. Select what is most suitable for your heat pump.
You will receive a reminder about filter cleaning in the display. The default
setting for the reminder is every three months, however, if the power to
F750 is interrupted the countdown begins again.
1. Switch off the heat pump.
2. Remove the upper front cover by pulling straight out.
3. Pull out the filter cassette.
4. Take out the filter and shake/vacuum off any dirt. Do not use water
or other liquids for cleaning.
5. Check that the filter is not damaged.
6. Carry out assembly in reverse order.
Even if the filter appears clean, dirt collects in it and this affects the efficiency of the filter. Therefore, replace it after 2 years. New filters can be
ordered via the installer.

Check pressure
F750 has a pressure gauge which shows the heating system pressure. The
pressure should be between 0.5 and 1.5 bar, but varies during temperature
changes. If the pressure drops to 0 or rises to 2.5 frequently, contact your
installer for troubleshooting.

Chapter 2 | The heat pump – the heart of the house
NIBE™ F750
Safety valves
F750 has two safety valves, one for the hot water heater and one for the
climate system.
The water heater's safety valve sometimes releases a little water after hot
water usage. This is because the cold water, which enters the water heater,
expands when heated causing the pressure to rise and the safety valve to
open. The climate system's safety valve must be completely sealed and
not release any water.
The function of the safety valves must be checked regularly. The valves are
accessed via the service hatch. Perform checks as follows:
1. Open the valve by turning the knob anti-clockwise carefully.
2. Check that water flows through the valve.
3. Close the valve by releasing it. If it does not close automatically when
released, turn it anti-clockwise slightly.
4. The climate system may need to be refilled after checking the safety
valve, see the section “Filling the climate system”.

Cleaning the overflow cup
Condensation forms when the heat pump is working. This condensation
is led off and collected in an overflow cup. In addition to water a certain
amount of dust and particles are also gathered in the overflow cup.
The overflow cup should be checked in conjunction with checking the
safety valves or once every three months and cleaned if necessary.

Filling the climate system
If the pressure is too low, increase as follows:
1. For F750, stainless steel: Check if the flexi hose supplied is connected
between the two filler valves. Adjust the hose if this has not been
done.
2. For F750, copper: Open the filling valve. The boiler section and the
rest of the climate system are filled with water.
For F750, stainless steel: Open the filler valves. The boiler unit and the
rest of the climate system are filled with water.
3. After a while the pressure rises on the pressure gauge. When it is approx. 1.0 bar close the filler valve(s).

Venting the climate system
In event of repeated filling of the climate system or if bubbling sounds are
heard from the heat pump the system may need venting. This is carried
out as follows:
1. Set the switch in mode and wait approx. 30 seconds.
2. Turn off the power supply to the heat pump.
3. Vent the heat pump via the vent valves and the rest of the climate
system via the relevant vent valves.
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 are opened.
Therefore hold the vent valves open at least 5 seconds.

Saving tips
Your heat pump installation produces heat and hot water. This occurs via
the control settings you made.
Factors that affect the energy consumption are, for example, indoor temperature, 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:
႑ During the adjustment period (winter time) all thermostat valves should

that the correct indoor temperature is obtained, in most rooms, regardless of the outdoor temperature. In rooms where a lower temperature
is required, the thermostat valves are lowered to the desired level. After
a few months, the remaining thermostats can be lowered slightly to
avoid an increase of the room temperature due to solar radiation, stove
heat etc. Further reductions may be required later on.
႑ You can lower the temperature when away from the house by
scheduling "holiday setting" in menu 4.7. See page 61 for instructions.
႑ You can reduce the ventilation speed when you are away by scheduling
in menu 1.3.3. See page 37 for instructions.

Increasing the indoor temperature one degree increases the energy consumption by approx. 5%.
Domestic electricity
In the past it has been calculated that an average Swedish household has
an approximate annual consumption of 5000 kWh domestic electricity/year. In today's society it is usually between 6000-12.000 kWh/year.

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.
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.

If a room sensor is not activated, the desired offset of the heating curve is
set. This setting applies to all climate systems without room sensors. One
step is usually enough to change the room temperature by one degree,
but in some cases several steps may be required.
Vacation scheduling starts at 00:00 on the start date and stops at 23:59
on the stop date.
TIP
Complete holiday setting about a day before your return so that room
temperature and hot water have time to regain usual levels.
TIP
Set the vacation setting in advance and activate just before departure
in order to maintain the comfort.
Caution
If you choose to switch off hot water production during the vacation
“periodic increase" (preventing bacterial growth) are blocked during
this time. "periodic increase" started in conjunction with the vacation
setting being completed.
Caution
If the exhaust air temperature falls below 16 °C, the compressor is
blocked and the electrical addition is permitted to intervene. When the
compressor is blocked heat is not recovered from the exhaust air.

4 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 fault source. See page 52 for more information about menu 3.1.
Manage alarm
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.
/RZ SUHVVXUH DODUP
DODUP
LQIR DFWLRQ
Alarm
UHVHW DODUP
DLG PRGH
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, contact your
installer.
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.
Chapter 4 | Disturbances in comfort
NIBE™ F750
67
NOTE
To select aid mode an alarm action must be selected in menu 5.1.4.
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.
If the alarm does not reset, contact your installer for suitable remedial action.
NOTE
Always communicate the product's serial number (14 digits) when reporting a fault.
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:
႑ The switch's position.
႑ Group and main fuses of the accommodation.
႑ The property's earth circuit breaker.
႑ Correctly set load monitor (if installed).
Low hot water temperature or a lack of hot water
႑ Closed or choked filling valve for the hot water heater.
႑ Open the valve.
႑ Mixing valve (if there is one installed) set too low.
႑ Adjust the mixer valve.
႑ Heat pump in incorrect operating mode.

6 Glossary
Additional heat:
The additional heat is the heat produced in addition to the heat supplied
by the compressor in your heat pump. Additional heaters can be for example, immersion heater, electric heater, gas/oil/pellet/wood burner or
district heating.
Buffer vessel
A buffer vessel increases the system volume and removes the unwanted
temperature variations that can otherwise be sent out on the climate system. This ensure the running of the heat pump and reduces the heat spikes
that could otherwise be heard from the climate system.
Calculated flow line temperature
The temperature that the heat pump calculates that the heating system
requires for an optimum accommodation temperature. The colder the
outdoor temperature, the higher the calculated supply temperature.
Circulation pump
Pump that circulates liquid in a pipe system.
Climate system
The climate system can also be called the heating and/or cooling system.
The building is cooled or heated using radiators, under floor coils or convector fans.
Compressor
Compresses the gas state refrigerant. When the refrigerant is compressed,
the pressure and the temperature increase.
Condenser
Heat exchanger where the hot gas state refrigerant condenses (cooled
and becomes a liquid) and releases heat energy to the house heating and
hot water systems.
Disturbances in comfort
Disturbances in comfort are undesirable changes to the hot water/indoor
comfort, for example when the temperature of the hot water is too low
or if the indoor temperature is not at the desired level.
A malfunction in the heat pump can sometimes be noticed in the form of
a disturbance in comfort.

In most cases, the heat pump notes operational interference and indicates
this with alarms and shows instructions in the display.
Domestic hot water
The water one showers in for example.
Electrical addition
This is the electricity that, for example, an immersion heater produces
when the compressor's output is not sufficient to fulfil the property's
heating demand.
Emergency mode
A mode that can be selected using the switch in the event of a fault, which
means that the compressor stops. When the heat pump is in emergency
mode, the building and/or hot water is heated using an immersion heater.
Evaporator
Heat exchanger where the refrigerant evaporates by retrieving heat energy
from the air which then cools.
Exhaust air
The air that comes from the exhaust air device in the various rooms of the
accommodation, to F750.
Exhaust air devices
Vents, usually in the ceiling, in the kitchen/bathroom/clothes closet where
the air is drawn in to be forwarded to F750.
Expansion valve
Valve that reduces the pressure of the refrigerant, whereupon the temperature of the refrigerant drops.
Expansion vessel
Vessel with heating medium fluid with the task of equalising the pressure
in the heating medium system.
Extract air
The air that the heat pump has retrieved heat from and which has therefore
been cooled. This air is blown out of the building.
Filtering time
Enter the time the average outdoor temperature is calculated on.

Flow pipe
The line in which the heated water is transported from the heat pump out
to the house heating system (radiators/heating coils).
Heat exchanger
Device that transfers heat energy from one medium to another without
mixing mediums. Examples of different heat exchangers are evaporators
and condensers.
Heat factor
Measurement of how much heat energy the heat pump gives off in relation
to the electric energy it needs to operate. Another term for this is COP.
Heating curve
The heating curve determines which heat the heat pump is to produce
depending on the temperature outdoors. If a high value is selected, this
tells the heat pump that it must produce a lot of heat when it is cold outdoors in order to achieve a warm indoor temperature.
Heating medium
Hot liquid, usually normal water, which is sent from the heat pump to the
house climate system and makes the accommodation warm. The heating
medium also heats the hot water.
Heating medium side
Pipes to the house’s climate system make up the heating medium side.
Hot water heater
Container where domestic water is heated. Is located inside the heat pump,
but an extra hot water heater can be installed in the event of large hot
water requirements.
Mixing valve
A valve that mixes the cold water with the hot water leaving the heater.
Outside sensor
A sensor that is located outdoors. This sensor tells the heat pump how hot
it is outdoors.
Pressostat
Pressure switch that triggers an alarm and/or stops the compressor if nonpermitted pressures occur in the system. A high pressure pressostat trips
if the condensing pressure is too great. A low pressure pressostat trips if
the evaporation pressure is too low.

Radiator
Another word for heating element. They must be filled with water in order
to be used with F750.
Refrigerant
Substance that circulates around a closed circuit in the heat pump and
that, through pressure changes, evaporates and condenses. During evaporation, the refrigerant absorbs heating energy and during condensing,
gives off heating energy.
Return pipe
The line in which the water is transported back to the heat pump from
the house heating system (radiators/heating coils).
Return temp
The temperature of the water that returns to the heat pump after releasing
the heat energy to the radiators/heating coils.
Room sensor
A sensor that is located indoors. This sensor tells the heat pump how hot
it is indoors.
Safety valve
A valve that opens and releases a small amount of liquid if the pressure is
too high.
Shunt
A valve that mixes the hot water with a small amount of slightly cooler
water.
Shuttle valve
A valve that can send liquid in two directions. A shuttle valve that enables
liquid to be sent to the climate system, when the heat pump produces
heating for the house, and to the hot water heater, when the heat pump
produces hot water.
Supply temperature
The temperature of the heated water that the heat pump sends out to
the heating system. The colder the outdoor temperature, the higher the
supply line temperature becomes.
