For the Installer
FIGHTER 310P
All electrical equipment except for the outdoor sensor
has been connected at the factory.
Disconnect the heat pump before insulation testing the
house wiring.
FIGHTER 310P does not include an isolator switch on
the incoming electrical supply. The installation must
therefore be preceded by a circuit-breaker with at least
a 3 mm breaking gap according to applicable norms.
The heat pump must be installed via an isolator switch.
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”.

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).
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.
Resetting the temperature limiter may only be carried
out by a qualified installation engineer after checking
the electrical equipment.

NOTE!
The electrical installation, wiring and
any service work must be done in strict
conformity to current regulations
under the supervision of a qualified
electrician.

FIGHTER 310P is delivered with an 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.
