Chapter 1 | Important information
NIBE F370
Area checks
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.
Working method
The work must be carried out in a controlled way to minimise the risk of contact
with combustible gas or liquid during the
work.
General for the working range
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 for the presence of refrigerant
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.
Presence of fire extinguishers
If hot work is carried out on the heat pump,
a powder or carbon dioxide fire extinguisher must be to hand.
Absence of ignition sources
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.
NIBE F370
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.
Ventilated area
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.
Checking cooling equipment
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.
■ The filling quantity is appropriate for the
size of the space where the parts that
contain refrigerant are installed.
■
Ventilation equipment and outlet work
correctly and without obstructions.
■
If an indirect refrigerant circuit is used,
check whether the secondary circuit contains refrigerant.
■
All markings of equipment are visible and
clear. Markings, signs and similar that are
not clear must be replaced.
Chapter 1 | Important information
5
■
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.
Checking electrical equipment
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.
The following checks must be carried out
at the initial safety checks.
■ That the capacitors are discharged. Discharging must be done safely, to prevent
the risk of sparking.
Ensure that the apparatus is secured properly.
Check that seals or sealing materials have
not deteriorated to a degree that they can
no longer prevent combustible gases from
entering. Replacement parts must meet
the manufacturer's specifications.
NOTE
Use of silicone seals can hamper the
efficiency of certain types of leaktracing equipment. Components
with built in safety do not need to
be isolated before starting work.
Wiring
■
That no powered electrical components
or live cables are exposed when filling or
collecting refrigerant or when the system
is flushed.
Check that cabling will not be subject to
wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also
take into account the effects of aging or
continual vibration from sources such as
compressors or fans.
■
That the system is continually earthed.
Leak testing
Repairing sealed components
When repairing sealed components, all
electrical supply must be disconnected
from the equipment that is being repaired
before any sealed covers or similar are removed. If it is absolutely necessary to have
an electricity supply to the equipment
during the service, continuously activated
leak tracing must be performed at the most
critical points in order to warn of any dangerous situations.
6
Pay particular attention to the following
so that the sheath is not changed in a way
that affects the protection level when
working with electrical components. This
means damage to cables, unnecessary
amounts of connections, terminals that do
not follow the original specifications,
damaged gaskets, incorrect grommets etc.
Chapter 1 | Important information
The following leak detection methods are
deemed acceptable for systems containing
flammable refrigerants.
Electronic leak tracers must be used to detect combustible refrigerant; but the leak
tracer may not be sufficiently sensitive or
may need to be recalibrated (the leak tracing equipment must be calibrated in an
area completely free from refrigerant). The
leak tracer must not be a potential source
of ignition and must be suitable for the
NIBE F370
relevant refrigerant. The leak tracing
equipment must be set and calibrated for
the relevant refrigerant, to ensure that the
gas concentration is a maximum of 25%
of the lowest combustible concentration
(Lower Flammability Limit, LFL) of the relevant refrigerant.
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.
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. Drain the refrigerant.
2. Flush the circuit with inert gas.
3. Drain the circuit.
4. Flush again with inert gas.
5. Open the circuit by cutting or burning.
Collect the refrigerant in the intended
container. Flush the system with oxygenfree nitrogen to make the device safe. This
process may need to be repeated several
times. Compressed air and oxygen may not
be used.
NIBE F370
Flush the system by breaking the vacuum
with oxygen-free 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 oxygen-free
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.
Ensure that the vacuum pump's outlet is
not near to ignition sources and that there
is satisfactory ventilation by the outlet.
Filling
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.
■
Containers must be stored upright.
■
Ensure that the cooling system is grounded before the system is filled with refrigerant.
■
Mark the system once filling is complete
(if not already marked).
■
Take extra care not to overfill the cooling
system.
Before refilling the system, pressure test it
with oxygen-free nitrogen. Leak test the
system after filling but before using the
system. Perform an additional leak test
before leaving the installation.
Decommissioning
Before performing this procedure, the
technician must be familiar with the
equipment and all its component parts.
Chapter 1 | Important information
7
Good practice prescribes that all refrigerant
is collected safely. Before the work is carried
out, samples of 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.
1. Familiarise yourself with the equipment
and its use.
2. Isolate the system electrically.
3. Before starting the procedure, ensure
that:
■ necessary equipment for mechanical
handling of the refrigerant container
is available
■
all necessary personal safety equipment is available and used correctly
■
the collection process is continuously
supervised by an authorised person

the collection equipment and containers meet appropriate standards.
Pump the refrigerant system to vacuum,
if possible.
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.
Check that the refrigerant container is
on the scales before starting to collect.
Start the collection device and collect
according to the manufacturer's instructions.
Do not overfill the containers (max. 80
% (volume) liquid content).
Do not exceed the containers' maximum
permitted working pressure – not even
temporarily.
When the containers have been filled
correctly and the process is complete,
close all shut-off valves in the equip-

ment and remove and containers and
equipment from the installation immediately.
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 collection 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.
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
NIBE F370
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.
General
Serial number
The serial number can be found at the bottom right of
the front cover and in the info menu (menu 3.1).
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.
If compressors/compressor oil are/is to be
removed ensure that the affected device
is drained to an acceptable level to ensure
that no combustible refrigerant remains in
the lubricant. Compressors must be drained
before being returned to the supplier. Only
electrical heating of the compressor housing may be used to quicken draining. Drain
oil from the system in a safe manner.
Miscellaneous
Maximum amount of refrigerant: See
Technical specifications.
■ Everyone who works with or opens a refrigerant circuit must have a current, valid
certificate from an accredited industry issuing body, which states that, according
to the industry's recognised assessment
standard, they have the authority to safely
handle refrigerants.

NIBE F370
Cleaning the climate system
System diagram
When the water heater and the climate system have
been filled with water, F370 must operate at maximum
normal temperature for at least one hour. Thereafter
the system must be drained of water and refilled. See
section Draining the climate system on page 49.
F370 consists of a heat pump, water heater, immersion
heater, fan, circulation pump and control system.F370
is connected to the ventilation system and heating medium circuits.
Before installing the heat pump in an existing system, it
is important that the system is properly flushed through.
Even if the heat pump is to be installed in a new system,
the heat pump and system should be flushed.
NOTE
Ensure that cleaning agent has been removed
from the entire system before adding inhibitor.
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 heating system
water, whereupon the refrigerant changes state from
gas to liquid.
After flushing an inhibitor should be used for long-term
anti-corrosion protection.
The refrigerant then goes via filters to the expansion
valve, where the pressure and temperature are reduced.
NIBE Energy Systems Limited recommends water treatments (supplied by e.g. Fernox and Sentinel) specifically
designed for heat pumps.
The refrigerant has now completed its circulation and
returns to the evaporator.
Caution
Ensure that incoming water is clean. When using
a private well, it may be necessary to supplement with an extra water filter.
Maximum boiler and radiator volumes
The volume 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.
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 219
litres at the above pre-pressure.

Installation alternative
F370 can be installed in several different ways, some of
which are shown below.
Further option information is available at
www.nibe.co.uk and in the respective assembly instruction for the accessory used. See page 55 for a list of accessories that can be used with F370.
Extra hot water heaters
The heat pump should be supplemented with an extra
water heater, if a large bath tub or other significant
consumer of hot water is installed.
Water heater with immersion heater
If it is possible to use a water heater with an immersion
heater, connect it as illustrated below.

Chapter 4 | Pipe and ventilation connections
NIBE F370
General ventilation connection
Ventilation flow
Ventilation installation must be carried out in accordance
with current norms and directives.
Connect F370 so that all of the exhaust air, except kitchen 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 28 l/s (100 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 start-up
and when there is nobody at home), the minimum value
is 31 l/s (110 m³/h).
To prevent fan noise being transferred to the ventilation
devices, silencers should be installed in the duct system.
In the event of ventilation devices in noise-sensitive
rooms, silencers must be installed.
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 along its entire length. Ensure that the condensation insulation is fully 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.
Because the heat pump contains the flammable refrigerant propane (R290), the air ducting system must be
earthed. This is done by making a sound electrical connection to the exhaust air and vented air ducts with the
enclosed earth cables (2 pcs). The cables must then be
connected to the earth pins on top of the top cover.
Exhaust air duct /kitchen fan
Exhaust air duct (kitchen fan) must not be connected to
F370.
To prevent cooking odours from being led to the F370,
the distance between the kitchen fan and the exhaust
air valve must be observed. The distance should not be
less than 1.5 m.
Always use a kitchen fan when cooking.
The heat pump’s installation area must be ventilated to
at least 5 l/s (18 m³/h)
Ensure that the ventilation openings are not blocked.
Set the ventilation capacity in the heat pump's menu
system (menu 5.1.5).
(menu 5.1.5)
If the exhaust air temperature falls below 16 °C, the
compressor is blocked and electric additional heat is
permitted. Heat is not recovered from the exhaust air
when the compressor is blocked.
Adjusting ventilation
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.
Immediately after installation adjust the ventilation so
that it is set according to the projected value of the
house.
Incorrect ventilation adjustment 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.

Room sensor
F370 is supplied with a room sensor enclosed (BT50).
The room sensor has up to three functions:
1. Show current room temperature in F370'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 F370'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.

Preparations
1. Check that the switch (SF1) is in position " ".
2. Check that the filling valve (QM11) is fully closed.
Caution
Check the miniature circuit-breaker (FA1) in the
heat pump. It may have tripped during transportation.
Venting the climate system
1. Turn off the power supply to the heat pump.
2. Vent the heat pump via the vent valve (QM20) 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 pipe from the container must be
drained of water before air can be released. This
means that the system is not necessarily bled
despite the flow of water when the bleed valve
(QM20) is opened.
Filling and venting
Filling the hot water heater
1. Open a hot water tap in the house.
2. Open the externally mounted filler valve. 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.

Filling the climate system
1. Check that the shut-off valves for the heating system
(QM31) and (QM32) are open.
2. Open the vent valve (QM20).
3. Check that the supplied flexi hose is connected
between connection (QM11) and connection
(QM13). Connect the hose if this has not been done.
4. Open the filler valves (QM11), (QM13). The heating
section and the rest of the climate system are filled
with water.
5. When the water exiting the vent valve (QM20) is no
longer mixed with air, close the valve. After a while,
the pressure rises on the pressure gauge (BP5). When
the pressure reaches 2.5 bar (0.25 MPa), the safety
valve (FL2) starts to release water. Close the filler
valves (QM11), (QM13).
6. Reduce the boiler pressure to the normal working
range (approx. 1 bar) by opening the vent valve
(QM20) or the safety valve (FL2).
7. Check that there is water in the overflow cup (WM1).

Setting the ventilation
Commissioning without fan
Ventilation must be set according to applicable standards. Set the fan speed in menu 5.1.5.
The heat pump can be run without recovery, as only an
electric boiler, to produce heat and hot water, for example before the ventilation installation is complete.
Even if ventilation is roughly set at installation it is important that a ventilation adjustment is ordered and permitted.
NOTE
Order a ventilation adjustment to complete the
setting.
Enter menu 4.2 - "op. mode" and select "add. heat only"
Enter menu 5.1.5 - "fan sp. exhaust air" and reduce 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.

Safety valves
Draining the water heater
F370 has three safety valves, two for the water heater
and one for the climate system.
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.
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 water heater
To clean the water heater, remove the upper panel and
the insulation. Then open the flange for easy access.
Draining the climate system
Service actions
In order to carry out service on the climate system, it may
be easier to drain the system first.

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 in the heating section is controlled
by a fixed thermostat (BT30) at 63°C.
■ The compressor is off and only the fan, heating medi-
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 drained through the 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.
um pump and the electric additional heat are active.

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.
