Installation and Maintenance Instruction.
FIGHTER 360P is an exhaust air heat pump. This
means that it collects the energy in the
ventilation air and uses it for hot water and room
heating.
Microprocessors ensure that the heat pump always
works efficiently.
FIGHTER 360P is a Swedish-made quality product
which will last a long time and run reliably without
unpleasant surprises.
For Home Owners

System description 3
For Home Owners
FIGHTER 360P
FIGHTER 360P 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 heat pump. The heat pump
must be installed in a ventilation system intended for
mechanical exhaust air.
The output of the immersion heater is max 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 refrigerant is then compressed in a compressor,
causing the temperature to rise considerably.
The warm refrigerant is fed to the condenser, which is
in the boiler water. Here the refrigerant gives off its
heat to the boiler water, so that its temperature drops
and the refrigerant changes state from gas to liquid.
The refrigerant then goes via filters to the expansion
valve, where the pressure and temperature are further
reduced.
The refrigerant has now completed its circulation and
returns to the evaporator.

When the room air has
passed through the heat
pump it is discharged. The
temperature of the air has
been significantly reduced
as the heat pump has
extracted the energy in the
room air.
The air from the
kitchen fan goes
directly out into a
separate duct.
The warm room
air is fed to

Automatic heating control system
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 its gets, the hotter
the radiators must be.
This adjustment is made automatically, however the
basic settings must first be made on the boiler, see the
section Room temperature – Basic setting.

Room temperature 7
For Home Owners
FIGHTER 360P
The basic heating is set using menu 2.4 and with the
Offset heating curve 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
When the room temperature is too low, the heating
curve value is increased in menu 2.1 by one incre-
ment.
When the room temperature is too high, the heating
curve value is decreased in menu 2.1 by one incre-
ment.
Warm weather conditions
If the room temperature is low, increase the offset
heating curve setting by one step.
If the room temperature is high, reduce the offset
heating curve 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
Offset heating curve knob
anticlockwise or clockwise. One to three lines approxi-
mately represents a 1 degree change in room tempera-
ture.
NOTE! An increase in the room temperature may be
inhibited by the radiator or floor heating thermostats, if
so these must be turned up.

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.
Check that the ventilation opening (84), behind the
lower front cover, is not blocked. Clean if necessary.
The heat pump's air filter needs to be cleaned regu-
larly (approximately 4 – 5 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.
■Pull out the holder (78).
■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.
The cleaning time intervals vary depending on the
amount of dust in the exhaust air.
Also see the section, Alarm indications in the display,
FILTER MONITOR.
The heat pump and its ventilation ducting require some
regular maintenance when the following points should
be checked.

For Home Owners
FIGHTER 360P
The working range of the heating system is normally
0.5 – 1.5 (bar) Check this on the pressure gauge (42).
FIGHTER 360P has two safety valves, one for the
heating system and one for the water heater.
The heating system’s safety valve (52) must be com-
pletely tight, but the hot water safety valve (47) may
occasionally release some water after hot water has
been used. This is because the cold water, which
enters the water heater to replace the hot water,
expands when heated causing the pressure to rise
and the safety valve to open.
Safety valve (52) should be checked once a year, while
safety valve (47) should be checked 4 times a year.
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 heat-
ing system.

NOTE!
Work on the refrigerant system must be
done by authorised personnel in
accordance with the relevant legislation
on refrigerants, supplemented by
additional requirements for flammable
gas, for example, product knowledge as
well as service instruction on gas
systems with flammable gases.
FIGHTER 360P should be transported and stored ver-
tically in the dry. The FIGHTER 360P may however be
carefully laid on its back when being moved into a
building.
The heat pump contains highly inflam-
mable 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
NOTE!
The transport guard around the compressor
must be removed before starting.
The lifting straps on top of the heat pump should be
removed before starting as these can otherwise cause
increased sound levels. These are removed by first
cutting with a knife and then pulling them out.

General information for the installer 11
FIGHTER 360P
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. A new inspection must be made when
changing the heat pump or the expansion vessel.
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, a wall that backs on to a bedroom or some
other room where noise would be a problem should be
avoided. 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.
Electric boiler mode
Installation
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 add-
ing 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 pres-
sure affects the ability of the expansion vessel to han-
dle the expansion of the water. The maximum system
volume excluding the boiler is 285 litres at the above
initial pressure.
Maximum boiler and
radiator volumes

For the Installer
The unit can be used exclusively as an electric boiler,
to produce heat and hot water, for example before the
collector installation is complete.
Three different operating modes are possible.
Option 1. Electric boiler mode with ventilation
Select menu 8.31 Electric boiler.
Activate Yes.
Option 2. Electric boiler mode without ventilation
Select menu 8.31 Electric boiler.
Activate Yes.
Select fan Off using the Fan speed push button.
Option 3. Standby mode “ ”
This mode is used when an outdoor sensor is not con-
nected. The heat pump's compressor and electronic
control are disabled in the “ ” position.
The fan is operational (speed I) and the immersion
heater is controlled by a separate thermostat.
The numerical display is off. The automatic heating
control system is not operational, so manual shunt
operation is required. This is done by turning the
adjuster screw to manual mode and then turning the
shunt lever to the required position.
NOTE!
When returning to normal mode, do
not forget to reset the shunt lever to
the original position by turning the
adjuster screw to A.

Pipe connections
FIGHTER 360P
12
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 DUT, the highest recommended
temperatures are 55 °C on the supply 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. In oth-
er words, in a system where the radiator flow might
stop because all thermostat valves are closed, there
must be a bypass valve to protect the circulation
pump.
The total volume is 240 litres, with 170 litres in the
water heater and 70 litres in the double-jacket space.
The pressure vessel in the FIGHTER 360P is approved
for max 9.0 bar (0.9 MPa) in the water heater and
2.5 bar (0.25 MPa) in the double jacket space.
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.
Other heat sources can be docked to the FIGHTER
360P Accessories are needed. Contact NIBE AB for
information.
General Docking
NOTE!
The pipe work must be flushed
before the heat pump is connected,
so that any contaminants do not
damage the component parts.
For the Installer
To empty the water heater proceed as follows:
■Disconnect the overflow pipe from the drain con-
nection (79) and connect a hose to a draining
pump instead. Where no draining pump is availa-
ble, the water can be released into the overflow
funnel (99).
■Open the safety valve (47).
■Open a hot water tap to let air into the system. If
this is not enough, undo a pipe coupling (74) on
the hot water side and pull out the pipe.
Emptying the water heater
Tap water connection
Hot and cold water are connected to pos (74) (hot
water) and (73) (cold water).
The attendant expansion vessel (107) must be con-
nected to the hot water system.
The heat pump should be supplemented with an elec-
tric water heater if a bubble pool or other significant
consumer of hot water is installed.
If the heater is equipped with a valve connection Ø of
15 mm, this should be replaced with an equivalent
(split) Ø 22 mm coupling.
Appropriate heaters are COMPACT 100-300 for floor-
mounting and EMINENT 35-100 for wall-mounting.
1. Split the valve coupling.
2. Attach the valve coupling section to the heater’s
incoming cold water.
3. Attach the mixing valve section to the heater’s out-
going hot water.
4. Plug the split on the valve coupling section.

Ventilation connection
FIGHTER 360P
For the Installer
14
FIGHTER 360P 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 360P is equipped with a ventilation
opening in the base. As a result, an air flow of about 5
m3/h (1,4 l/s) is taken directly from the room where the
heat pump is installed.
Changing the ventilation capacity is described under
Electrical connection - Setting the fan capacity. See
also Circuit diagram. The numbering of the curves
refers to the numbering on the fan terminal block (22).
To obtain the necessary air exchange in every room of
the house, the exhaust air devices must be correctly
positioned and adjusted. A defective ventilation instal-
lation 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
air devices, it may be a good idea to install a silencer
in the duct. This is especially important if there are
exhaust air devices in bedrooms.
As the heat pump contains a flammable refrigerant in
the form of propane (R290), the air ducting system
must be earthed.This is done by making a sound elec-
trical connection to the exhaust air and vented air
ducts with the two earthing cables supplied.The cables
must then be connected to the earthing studs on top
of the top cover.
Connections should be made via flexible hoses, which
must be installed so that they are easy to replace. The
extract air duct must be provided with diffusion-tight
insulation over its entire length. Provision must be
made for inspection 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. All joins in the ducting must be
sealed and pop-riveted to prevent leakage.
The air duct system should, at a minimum, be of air
tightness class B.
The diagram below shows the available ventilation
capacity.

For the Installer
FIGHTER 360P
FIGHTER 360P must be installed via an isolator
switch. Other electrical equipment, except the outdoor
sensor and the current sensors, are connected at the
factory.
Disconnect the heat pump before insulation testing
the house wiring.
FIGHTER 360P can be connected to a single phase
power suppply.
The connection is made according to the illustrations
below depending on the desired maximum output.
Max phase current, single phase
The knob (101) should always be set to position D
when using a single phase power supply.
The two immersion heaters have a total maximum out-
put of 13.5 kW. The power rating as set at the factory
is 7.5 kW, which corresponds to position C on the knob
(101) on the load monitor card (2).
Connection
Single phase connection
Output 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 1 or “ ” until the boiler has
been filled with water. Otherwise the
temperature limiter, thermostat,
compressor and the immersion heater
can be damaged.
The automatic heating control system, circulation
pump (16) and its cabling, are internally fuse protected
with a miniature circuit breaker (7).
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 between
90 and 100 °C; it can be manually reset by pressing
the button on the temperature limiter.

Connecting the outside sensor
Install the outside sensor in the shade on a wall facing
north or north-west, so it is unaffected by the morning
sun. The sensor is connected with two-wire cable to
terminal block (14) positions 1 and 2, on the load mon-
itor card (2).
If a conduit is used it must be sealed to prevent con-
densation in the sensor capsule. The minimum cable
cross section should be 0.4 mm2up to lengths of 50
metres, for example, EKKX or LiYY.
Access to the lower electrical connections
Open the centre front cover by removing the four
screws. The load monitor card (2), microprocessor
card (34), etc are now accessible on the left-hand side.
Remove the protection plate by loosening the four
screws to gain access to the right-hand side.

For the Installer
Centralised load control/Tariff
In those cases centralised load control or tariff control
is used this can be connected to the terminal block (14)
on the load monitor card (2), which is positioned behind
the centre front cover.
Tariff "A"
When parts of the electrical output (how much is deter-
mined by the max output) are to be disconnected, a
potential free contact function is connected between 5
and 7 on terminal block (14).
Tariff "B"
When the complete electrical output is to be discon-
nected, a potential free contact function is connected
between 6 and 7 on terminal block (14).
Load monitor
FIGHTER 360P is equipped with an internal load mon-
itor.
When the load monitor senses an overcurrent on one
of the phases, the immersion heater will step down the
output until it can be connected again.
The control system must be set for the installation’s
main fuse so that the load monitor can work correctly.
This is done using the knob (100), marked fuse on the
load monitor card (2), which is positioned behind the
centre front cover.
The supplied current sensor
is connected to the termi-
nal block’s (14) terminals marked 8 to 11. Terminal 11
is the common conductor for the three current sensors.

For the Installer
Contact for changing the room tempera-
ture
An external contact function can be connected to
FIGHTER 360P to change the supply temperature and
in doing so change the room temperature, for example,
a room thermostat or a timer. The contact should be
potential free and is connected between terminals 3 and
4 on terminal block (14) on the load monitor card (2).
When the contact is made the supply temperature is
higher or lower than the selected curve slope. The val-
ue for the change is set on menu 2.5, External adjust-
ment. The value is adjustable between -5 and +5. One
step corresponds to one step of the heating curve off-
set.
Contact for activation of Extra hot water
An external contact function can be connected to FIGHT-
ER 360P for activation of the Temporary Extra hot water
function. The contact should be potential free and non-
locking and is connected via the edge board connector
between positions 1 and 2 down on the lower part of the
left connection row on the load monitor card (2).
When the contact makes for at least one second the Tem-
porary Extra hot water function is activated. An automatic
return to the previously set function occurs after 24 hours.
This connection requires the accessory XTS 20.
Contact for activation of Fan speed II
An external contact function can be connected to
FIGHTER 360P for activation of fan speed II. The con-
tact should be potential free and non-locking and is
connected via the edge board connector between posi-
tions 3 and 4 down on the lower part of the left connec-
tion row on the load monitor card (2). When the contact
makes for at least one second Fan speed II is activated.
The return to normal speed occurs according to the
time set in menu 7.11, Return-time speed II. This con-
nection requires the accessory XTS 20.
