For Home Owners
General
In order to get the ultimate benefit from your heat pump FIGHTER 640P you should read through the
“For Home Owners” section in this Installation and Maintenance Instruction.
FIGHTER 640P is a combined exhaust air and outdoor 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 640P uses R290 (Propane) environmental brine.

System description
Principle of operation
FIGHTER 640P 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 boiler.
The heat pump must be installed in a ventilation system
intended for mechanical exhaust air.
When the exhaust air at room temperature together with
the outdoor air passes through the evaporator, the refriger-
ant 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, caus-
ing 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 refriger-
ant 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 re-
turns to the evaporator.
When the heat pump’s output is not solely sufficient an
integrated immersion heater is engaged. The output of the
immersion heater is 9.0kW. Output as set at the factory is
8.0 kW.

When the room air and
any outdoor air has passed
the heat pump the temper-
ature has dropped signifi-
cantly as the heat pump
has utilised the energy in
the air.

When the outdoor air is -5
°C or warmer it is led into the
heat pump.
G
The air from the
kitchen fan goes
directly out into a
separate duct.
B
The warm room air
is fed via the duct
system to FIGHTER
640P.
E
Outdoor air is drawn into
the house.
A
The warm room air is
drawn into the duct sys-
tem via the exhaust air
terminal.
F
Air is transported from
rooms with outdoor air
devices to rooms with
exhaust air devices.
D

house with both hot water
and room heating.
