In order to get the ultimate benefit from your heat pump FIGHTER 410P you should read
through the For Home Owners section in this Installation and Maintenance Instruction.
FIGHTER 410P is an exhaust air heat pump with preheated supply air . This means that it
collects the energy in the ventilation air and uses it for hot water and room heating.
A microprocessor ensures that the heat pump always works efficiently.
FIGHTER 410P is a Swedish-made quality product which will last a long time and run reli-
ably without unpleasant surprises.
For the installation engineer: Please, hand over to the home owner his manual after final-
ised installation.
To be filled in when the heat pump has been installed
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
Rights to make any design or technical modifications are reserved.

FIGHTER 410P comprises an electric boiler with a
copper lined water heater and a heat pump which
recovers energy from the ventilation air. The recovered
energy is supplied to the boiler. The heat pump must
be installed in a ventilation system intended for
mechanical exhaust and supply air.
The output of the immersion heater is max 8.0 kW
(Supplied output of 6.0 kW).
When the exhaust air at room temperature passes
through the evaporator, the refrigerant evaporates
because of its low boiling point. In this way the heat in
the room air is transferred to the refrigerant.The refrig-
erant is then compressed in a compressor, causing
the temperature to rise considerably. The warm refrig-
erant is fed to the condenser, which is in the boiler
water. Here the refrigerant gives off its heat to the boil-
er water, so that the temperature of the refrigerant
drops and the refrigerant changes state from gas to
liquid.The refrigerant then goes via filters to the expan-
sion valve, where the pressure and temperature are
further reduced.
The refrigerant has now completed its circulation and
returns to the evaporator.
A frost protection damper precedes the supply air side's
heating battery. This closes automatically when the sup-
ply air temperature after the battery drops below +5 °C

the channel number and the two on the right the
reading/setting of that channel.
In the event of a malfunction, an error message
is displayed alternately with channel number
and value. See Dealing with malfunctions – Indi-
cations on the numerical display.
NOTE! When switching from Standby mode “
” to normal mode “1” the numerical display
can remain dimmed for a brief period. This
can also occur at extremely low outdoor tem-
peratures.
Extra hot water
Pressing the Extra hot water button raises
the boiler temperature to about 60 °C, giv-
ing increased water capacity
for about 24 hours. In this
mode, the built-in lamp is con-
stantly lit.
Pressing the button again gives
a permanent function, which
raises temperature of the hot
water during 6 hours / day. The integrated lamp
flashes in this mode,
Pressing the button again resets the above
functions.
Heating curve offset
With the Heating curve offset button you
can change the offset of the heating curve
and thus the room temperature.

Fan speed
This switch is used for changing the fan
speed.
It is possible to switch between three different
speeds:
Position A: Reduced ventilation
Position B: Normal ventilation
Position C: Forced ventilation
Position B is normally used.
Position A is used on occasions when a lower
ventilation flow is acceptable in the house, for
example, when no one is in the house. This
position should not be used over long periods.
Otherwise there is a risk of an inferior indoor cli-
mate as well as damage due to dampness in
the house.
Position C is used on occasions when a higher
ventilation flow is sought in the house, for exam-
ple, when there are many people in the house.
This position should not be used over long peri-
ods. Otherwise this will increase energy con-
sumption and with that operating costs.

Room temperature
FIGHTER 410P
For Home Owners
8
The indoor temperature depends on several factors.
During the hot season, solar radiation and heat given
off by people and equipment are sufficient to keep the
house warm. When it gets colder outside, the heating
system must be started. The colder it is outside the
warmer the water circulating in the heating system
must be.
This adjustment is made automatically, however the
basic settings must first be made on the boiler, see the
section Room temperature — Default setting.
The basic heating is set with the Heating curve selec-
tion knob and with the Heating curve offset knob.
If you do not know the correct settings use the basic
data from the map opposite.
If the required room temperature is not obtained, read-
justment may be necessary.
NOTE! Wait one day between settings so that the tem-
peratures have time to stabilise.
Readjustment of basic settings.
Cold weather conditions
If the room temperature is low, increase the heating
curve selection setting by one step.
If the room temperature is high, reduce the heating
curve selection setting by one step.
Warm weather conditions
If the room temperature is low, increase the heating
curve offset setting by one step.
If the room temperature is high, reduce the heating
curve offset setting by one step.
Changing the room temperature manually.
If you want to temporarily or permanently lower or
raise the indoor temperature relative to the previously
set temperature, turn the Heating curve offset knob
anticlockwise or clockwise. One line approximately rep-
resents a 1 degree change in room temperature.
NOTE! An increase in the room temperature may be
inhibited by the radiator or floor heating thermostats, if
so these must be turned up.

Maintenance routines 9
FIGHTER 410P
For Home Owners
The building’s ventilation devices should be cleaned
regularly with a small brush to keep the correct venti-
lation.
The device settings must not be changed.
NOTE! If you take down more than one ventilation
device for cleaning, do not mix them up.
Also check the outdoor air’s intake grille (on the house
facade). Clean if necessary.
Cleaning the ventilation devices
The heat pump's air filter (63) needs to be cleaned
regularly (approximately 4 times per year). The interval
between cleaning operations varies and depends on
the amount of dust in the exhaust air.
■Set the switch to “0”.
■Open the upper front cover by pulling it out by the
lower edge, then lifting it up.
■Release the filter holder by turning the black knobs
a quarter of a turn anticlockwise.
■Pull out the holder, take out the filter and shake off
any dirt.
Check that the filter is not damaged. New original
filters can be ordered from NIBE.
■ Assembly takes place in the reverse order.
Every third month a reminder for cleaning the filter is
shown in the display as “A-01”. Note that the time will
be set to zero by setting the switch to "0".
Cleaning the air filter
When the exhaust air filter (63) has been severely
clogged or broken the evaporator may also need to be
cleaned. However, this should only be done in excep-
tional cases. Remove the plastic hose for waste con-
densation water from its mounting before cleaning. The
hose is straightened and the condensation water will
run out. The evaporator is cleaned with water; a mild
soap solution can be applied with a sponge, if neces-
sary. The hose is then reattached in its original posi-
tion, so that a water seal is formed.
The installation is checked with regard to abnormal
noise or leakage.

Warning to the
user!
If this unvented water heater develops
a fault, such as a flow of hot water
from the discharge pipe, switch the
heater off and contact the installer.

Check that the temperature of the extract air (channel
5) is clearly lower than the room temperature when the
compressor is operational, also see the section Deal-
ing with malfunctions - High extract air temperature. It
is normal that the extract air temperature varies.
The pressure gauge (42) reading should be between
the initial pressure of the expansion vessel (normally
0.5 bar) and 2.5 bar (25 mvp). See Commissioning

FIGHTER 410P has three safety valves, one for the
heating system and two for the water heater.
The safety valves must be checked regularly. Check
one valve at a time as follows:
■Open the valve.
■Check that water flows through the valve.
■Close the valve.
■The heating system may need to be refilled after
checking the safety valve (52), see the section
”Commissioning and adjustment” – ”Filling the
heating system”.

General information for the installer 11
For Home Owners
FIGHTER 410P
Current regulations require the heating installation to
be inspected before it is commissioned. The inspec-
tion must be carried out by a suitably qualified person.
The above applies to installations with a closed expan-
sion vessel. If the heat pump or the expansion vessel
is replaced, the installation must be inspected again.
The heat pump should preferably be erected with its
back about 10 mm from an outside wall in a utility room
or similar, to minimise noise nuisance. If this is not
possible, avoid placing it against a wall behind a bed-
room or other room where noise may be a problem.
Irrespective of the placement the wall should be sound
insulated. NOTE! The distance between the heat pump
and the wall should be at least 10 mm.
Route pipes so they are not fixed to an internal wall
that backs on to a bedroom or living room.
An area of approximately 15 cm is required on the left
side of the heat pump, at the temperature and pres-
sure valve (145) to enable access to the valve.
NOTE! Since a waterfilled FIGHTER 410P weighs
roughly 440 kilos, the floor must stand such a weight.
The heat pump should be transported and stored ver-
tically in the dry.
The heat pump contains highly inflamma-
ble refrigerant. Special care should be
exercised during handling, installation,
service, cleaning and scrapping to avoid
damage to the refrigerant system and in
doing so reduce the risk of leakage.
Transport and storage
Handling
Erecting the heat pump
Inspection of the installation
The volume of the expansion vessel
(85) is 12 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
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 initial pressure.

er.

For the Installer
12
Pipe installation must be carried out in accordance with
current norms and directives.
The system requires a low-temperature dimensioning of
the radiator circuit. At DUT, the highest recommended
temperatures are 55 °C on the flow line and 45 °C on
the return line.
When the circulation pump is running, the flow in the
radiator circuit must not be completely stopped.
The total volume is 240 litres, with 170 litres in the water
heater and 70 litres in the boiler section.
The pressure vessel in the FIGHTER 410P is approved
for max 9.0 bar (0.9 MPa) in the water heater and
2.5 bar (0.25 MPa) in the double shell section.
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 inju-
ry. These non-pressurised collecting pipes shall not be
used for anything else. A discharge pipe from the tundish
(108) connected to the expansion relief valve (47) (safe-
ty valve) shall also be connected to a drain in the same
way.
Discharge pipes from tundishes shall have av vertical
section of pipe at least 300 mm long, before any elbows
or bends in the pipework. See following picture.
General
If the vertical distance, 300 mm, is hard to fulfil a heigh-
tening console is available as an accessorie. No valve
should be fitted between the pressure reduction valve
(expansion valve) and the storage cylinder.

The delivered output in the diagram is calculated when dimension-
ing the heating system 55/45 °C respective 35/25 °C (floor heat-
ing).
The supply air battery is connected in parallel with the
radiator circuit and heats the house’s supply air.The addi-
tional output is determined according to the diagram.
The water flow through the supply air battery is set by
means of a trim valve (81).
When, for example, 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 battery 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 battery supplies the supply air with approximately
3.0 kW of additional output at -20 °C
NOTE! Vent the battery using the venting screw (5)
repeatedly in order to ensure the circulation through the
battery.

Ventilation connection 15
For Home Owners
FIGHTER 410P
FIGHTER 410P is connected so that all ventilation air
except the kitchen fan passes the evaporator (62) in
the heat pump. The lowest ventilation flow according to
current standards is 0.35 l/s per m2floor area. For
optimum heat pump performance the ventilation flow
should not be less than 110 m3/h. (31 l/s).
The heat pump's installation area should be ventilated
by at least 36 m3/h (10 l/s).
FIGHTER 410P is equipped with an internal ventilation
opening (84). As a result, an air flow of about 5 m3/h
(1.4 l/s) is taken directly at floor level from the room
where the heat pump is installed.
Changing the ventilation capacity is described under
Electrical connection - Setting the fan capacity. See
also the Circuit diagram. The numbering of the curves
refers to the positions on terminal block (22).
The choice of position and with that the fan speed is
made according to the following criteria:
■The supply air flow should be 80 % of the exhaust air
flow to avoid overpressure in the house.
■In position B (normal position) the planned exhaust
air respective supply air flow should be obtained in
the house. Fine adjustment is made using the termi-
nals in the different rooms. After which the position of
the terminal should not be changed.
■In position A (reduced position) a low exhaust air
respective supply air flow should be obtained. How
low is determined in each specific case. NOTE! The
exhaust air flow must never drop below 110 m3/h (31
l/s). Otherwise the heat pump's function may be jeop-
ardized. Tip: Select a position so that the exhaust air
flow is as close to 110 m3/h as possible without falling
below this value.
■In position C (forced position) a high exhaust air flow
respective supply air flow should be obtained. How
high is determined in each specific case. Tip: Select
as high a position as possible without the sound level
from the terminal in the house becoming trouble-
some.
The diagram below show the available ventilation
capacity.

To obtain the necessary air exchange in every room of
the house, the exhaust and supply air devices must be
correctly positioned and adjusted. The supply air flow
is adjusted to correspond to approximately 80 % of
the exhaust air flow. A defective ventilation installation
may lead to reduced heat pump efficiency and thus
poorer operating economy, and may result in damage
to the house.
NOTE!
A duct in a masonry chimney stack
must not be used for extract air.
To prevent fan noise being transferred to the exhaust
and supply air devices, it may be a good idea to install
a silencer in the duct.
As the heat pump contains a flammable refrigerant
(propane R290), the air ducting system must be
earthed. This is done by making a sound electrical
connection to the four ventilation ducts using the four
earthing cables supplied. The cables must then be
connected to the earthing studs on top of the top cov-
er.
Connections should 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 of the duct.
Make sure that there are no reductions of cross-sec-
tional area in the form of creases, tight bends etc,
since this will reduce the ventilation capacity. All joins
in the ducting must be sealed and pop-riveted to pre-
vent leakage.
The air duct system should, at a minimum, be of air
tightness class B and in general designed according
to applicable building standards.

All electrical equipment except for the outdoor sensor
has been connected at the factory.
Disconnect the heat pump before insulation testing the
house wiring.
The supply to the heat pump is connected to termi-
nal (9) via a strain relief. Connection must not be car-
ried out without the permission of the electricity sup-
plier and under the supervision of a qualified electri-
cian. The cable entry conduit is dimensioned for cable
with a max Ø 19 mm.
The power is controlled via a contactor which is oper-
ated by a microprocessor.
The temperature limiter (6) cuts off the supply to the
immersion heater if the temperature rises to 88 °C; it
can be manually reset by pressing the button on the
temperature limiter.
The temperature limiter (169) for the compressor cuts
off the supply to the compressor if the temperature
rises to 88 °C; it can be manually reset by pressing the
button on the temperature limiter.
As standard the output power of the immersion heater
is 8.0 kW. The supplied output is 6.0 kW.
Switching between different power outputs is done by
opening the front panel (see under Service — Open-
ing the front panel), and moving certain cables as
described under Electrical diagram — Changing the
output.
Connection Power rating as set at the
factory
NOTE!
Reset the temperature limiter,
it may have tripped during transport.
NOTE!
The switch (8) must not be moved
from “0” until the boiler has been
filled with water. The temperature
limiter, thermostat, compressor and
the immersion heater can otherwise
be damaged.
The automatic heating control system, circulation
pump (16) and its cabling, are internally fuse protected
with a miniature circuit breaker (7).
FIGHTER 410P is delivered with a 8 kW immersion
heater (1). It is started and stopped via the microproes-
sor card (34). If a failure occurs there is a temperature
limiter (6) (thermal cut-out) that is stopping the immer-
sion heater. An immersion heater without a tempera-
ture limiter is not allowed to be mounted.
The temperature limiters are accessible behind the top
front cover and are positioned to the right of the pan-
el.
The temperature limiters are reset by firmly pressing
in its buttons.
The temperature limiter may only be reset under the
supervision of a qualified installer.

Selection of the ventilation capacity is carried out in
connection with ventilation adjustment by connecting
the three white cables from the exhaust air fan respec-
tive the three black cables from the supply air fan to
the appropriate outlets on the terminal block (22). See
the illustration Ventilation connection — Fan diagram.
The cables correspond to fan and position as follows:
Black cable 094: Supply air fan, position A (reduced)
Black cable 096: Supply air fan, position B (normal)
Black cable 098: Supply air fan, position C (forced)
White cable 095: Exhaust air fan, position A (reduced)
White cable 097: Exhaust air fan, position B (normal)
White cable 099: Exhaust air fan, position C (forced)

Normally the immersion heater is permitted to run
even if the compressor has switched of because its
stop temperature has been reached (under the condi-
tion that the immersion heater is connected via the
operating mode selector). Furthermore, the flow tem-
perature is permitted to be as high as 65 °C.
These functions can be deactivated by moving the strap
from pins 1 and 2 to pins 2 and 3 as illustrated.
The numerical display will now show horizontal lines,
otherwise vertical.
Once the strap is in position on pins 2 and 3 the
immersion heater is only permitted to run when the
compressor is operational (except in defrosting mode).
In addition, the flow temperature is limited to maxi-
mum 60 °C.
