FIGHTER 600P
For Home Owners
2
In order to get the ultimate benefit from your heat
pump FIGHTER 600P you should read through the
For Home Owners section in this Installation and
Maintenance Instruction.
FIGHTER 600P is a combined exhaust air and out-
door air heat pump. This means it utilises energy in
ventilation air and outdoor air when this does not
fall below -5 °C. This energy is used for hot water
and heating the house.
A microprocessor ensures that the heat pump
always works efficiently.
FIGHTER 600P uses R290 (Propane) environmental
heat transfer fluid.
Installation engineers
To be filled in when the heat pump has been
installed
Setting Blocking temperature immersion heater
Pre-pressure expansion vessel (0.5 bar on delivery)

FIGHTER 600P consists of an electric boiler with enam-
elled water heater and a heat pump that recovers energy
from ventilation air and outdoor air when this is - 5 °C or
warmer. If the outdoor temperature is colder than - 5 °C
a damper closes so that only ventilation air is used as
the heat source. The recovered energy is supplied to the
heat pump. The heat pump must be installed in a ventila-
tion system intended for mechanical exhaust air.
When the exhaust air at room temperature together with
the outdoor air passes through the evaporator, the refrig-
erant evaporates because of its low boiling point. In this
way the heat in the 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 (plate heat
exchanger). Here the refrigerant gives off its heat to the
boiler water, so that its temperature drops and the refrig-
erant changes state from gas to liquid.
The refrigerant then goes via filters to the expansion
valve, where the pressure drops and the temperature is
lowered further.
The refrigerant has now completed its circulation and
returns to the evaporator.
When the heat pump’s output is not solely sufficient an
integrated immersion heater is connected in. The output
of the immersion heater is 9.0 kW.

For Home Owners
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 - 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 the default 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 respectively. One scale
marking corresponds to a change of about one degree
in the 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.
Default setting
Automatic heating control system
Changing the room
temperature
FIGHTER 600P offers the possibility to block immer-
sion heater operations as a function of the outdoor
temperature.
This means that when the outdoor temperature is
above a set value the immersion heater is not con-
nected despite compliance with the normal control
conditions. The set temperature should be selected so
that the heating requirement and the hot water
requirement are lower than the heat pump’s capacity
above this outdoor temperature. This temperature is
dependent on the size of the house, degree of insula-
tion, required room temperature and hot water usage.
Setting this temperature takes place according to the
following:
Scroll to channel 9 using the Channel selection but-
ton. The set value is then shown on the numerical dis-
play. To change the value, press the Ventilation but-
ton (increase the value one step) alternatively the
Extra hot water button (lowers the value one step).
The value can be set between +1 and +25 °C. If this
function is not required select +25 °C, which is also
the setting on delivery.
NOTE! The immersion heater can also be blocked
permanently irrespective of the outdoor temperature
by using the Operating mode button, see the section
Functions on the front panel - Functions on the front
panel.
NOTE! However, when the Extra hot water function is
activated the immersion heater is permitted to be
operational irrespective of the above blocking.
Blocking the immersion heater

Room temperature 7
FIGHTER 600P
For Home Owners
The association between the outdoor temperature and
the flow temperature is set using the Heating curve
selection (37) and Increase/reduce heat buttons (38).
The design flow temperature and the design outdoor
temperature are used as the input data in the adjoin-
ing diagrams to read the curve slope, which is set
using the Heating curve selection knob.
The setting on the Increase/reduce heat knob deter-
mines at which outdoor temperature heating should
stop. If the offset is set to 0 this means heating stops
at the outdoor temperature of + 20 °C. As you normal-
ly have a degree of free heating a value below zero
can be set with this knob.
The adjoining diagram shows the curve intersections
at offsets - 2, ± 0 and + 2. The default setting from the
factory is curve 10 on Heating curve selection and off-
set - 2 on Increase/reduce heat.
In those cases where the heating system’s design flow
temperature is not known the map below can be used
as a guide for setting Heating curve selection.
The first figure applies to a radiator system and the fig-
ure in brackets applies to floor heating installed in a
concrete floor structure where the max flow tempera-
ture is 35 °C. When the floor heating system is
installed in a wooden floor structure you can start with
the figure before brackets and reduce this value by
two units.
A suitable setting on the Increase/reduce knob is - 2
for radiator systems and -1 for floor heating.

For Home Owners
FIGHTER 600P
FIGHTER 600P has two safety valves, one for the
heating system and one for the water heater.
The heating system 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.
Both safety valves must be checked about four 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.
Checking the safety valves
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.

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
expansion vessel. A new inspection must be made
when changing the heat pump or the expansion ves-
sel.
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
bedroom or other room where noise may be a prob-
lem. 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. If
necessary, for example, with a low ceiling height, it is
possible to position the modules individually.
Route pipes so they are not fixed to an internal wall
that backs on to a bedroom or living room.
FIGHTER 600P has a venting screw located on the
front edge at the top. This should be easily accessible,
which should be considered during installation.
The heat pump should be transported and stored ver-
tically in the dry.
The heat pump contains highly inflam-
mable refrigerant. Special care should
be exercised during handling, installa-
tion, service, cleaning and scrapping to
avoid damage to the refrigerant system
and in doing so reduce the risk of leak-
age.

The volume of the expansion vessel (85) is 10 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.

the valve in the expansion vessel. The initial pressure
of the expansion vessel must be stated in the inspec-
tion 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
217 litres at the above initial pressure.

Channel description
FIGHTER 600P

Pipe connections14
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 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. 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.
A filter should be fitted on the return line to protect
component parts. The total volume is 244 litres, with
189 litres in the water heater and 55 litres in the boiler
section.
The pressure vessel in the FIGHTER 600P is
approved for max 9.0 bar (0.9 MPa) in the water
heater and 2.5 bar (0.25MPa) in the boiler 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 injury.

Ventilation connection 15
For the Installer
FIGHTER 600P
FIGHTER 600P 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 this ventilation flow
should not be less than 120 m3/h. (34 l/s). With
exhaust air flow greater than 200 m3/h the outdoor air
duct is not connected. Accordingly FIGHTER 600P is
only used as an exhaust air heat pump.
In those cases the exhaust air flow falls below 200
m3/h an outdoor air duct with adjustment damper
should be connected to the heat pump. The heat
pump then normally works with the fan at maximum.
The maximum capacity of the fan is then distributed
between the planned exhaust air and outdoor air. With
outside temperatures lower than approximately - 5 °C
the fan automatically slows down to the selected set-
ting and the heat pump’s internal damper shuts out
the outdoor air, whereby the planned exhaust air flow
is maintained.
The heat pump’s installation area should be ventilated
by at least 36 m3/h (10 l/s).
FIGHTER 600P 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 outlets on terminal (22).
See the section “Setting the ventilation”.
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. If a twin duct system is used for
the exhaust air, each system should be fitted with a
silencer. Because 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 electrical connection to the exhaust air, extract air
and outdoor air ducts using the three earthing cables
supplied. The cables must then be connected to the
earthing studs on top of the top cover.
Duct 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. The
outdoor air duct should be fitted with an adjustment
damper. 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. When the exhaust air flow is so great that no
outdoor air duct is fitted and the ventilation system is
connected only to the exhaust air sleeve the outdoor air
sleeve should be sealed. If the ventilation system is con-
nected to both the exhaust air sleeve and the ordinary
outdoor air sleeve the damper motor should be electri-
cally disconnected. This is done by removing the damper
motor’s cable ends on the relay card (terminals 36, 37
and 38) from the relay card and then insulated. The
damper can now be turned to the open position by hand
when the damper motor’s knob is pressed in.
The air duct system should, at a minimum, be of air tight-
ness class B.
The diagram below shows the available ventilation
capacity.

Adjustment
The kitchen flue must not be connected to FIGHTER
600P.
Exhaust air duct
FIGHTER 600P works in average size houses, with
both exhaust air and outdoor air. This gives greater
savings than by using just exhaust air. However, at
outdoor temperatures below approximately - 5 °C, the
outdoor air flow is closed by means of an internal
damper and the heat pump now works with just the
exhaust air. In larger houses only the exhaust air
ducts are connected as the exhaust air here contains
sufficient amounts of energy.

and (6) on terminal (14). The timer or the room ther-
mostat must have a potential free contact and have a
design where the circuit opens when a lower tempera-

originally selected setting for Heating curve offset by
three steps downwards.
An external switch that switches off the circulation
pump can be connected (first remove the strap) at
positions (4) and (5) on terminal (14). For example, a
thermostat can be connected that detects the flow
temperature and switches off the circulation pump, if
the flow temperature becomes too high. The switch or
thermostat must have a potential free contact and
have a design where the circuit opens when the circu-
lation pump should be switched off.

valves.
■Keep topping up and venting until all air has been
removed and the pressure is correct.
Venting the heating system
Air is initially released from the hot water and venting
may be necessary. If bubbling sounds can be heard
from the heat pump, the entire system requires further
venting. NOTE! Safety valve (52) also acts as a man-
ual venting valve. Operate it with care, since it opens
quickly. When the system is stable (correct pressure
and all air eliminated) the automatic heating control
system can be set as required. See the section Room

Draining the heating system
The output steps of the immersion heater can be dis-
