■ Set the switch (8) to “ ”. In this mode the elec-
tronics are disconnected, so the display window is
not lit. The thermostat (3) opens at 68 °C in this
mode.
■ Set the shunt (19) by hand (turn the adjuster screw
to manual mode and then turn the shunt lever to
the required position).
■ When the room temperature exceeds 16 °C set
switch (8) to “1”. NOTE! The display may still not be
lit, this comes on automatically when the boiler
temperature has dropped a few degrees. The com-
pressor has a start delay of at least 20 minutes.
■ Reset the shunt (19) by hand (turn the adjuster
screw to “A”).
■ Set the design capacity (35) on the circulation
pump’s switch (16). See the section Pipe connec-
tions - Pump and pressure drop diagram. Make
sure that the switch is not in an intermediate posi-
tion.

FIGHTER 410P
For the Installer

NOTE! The pipe from the container must be drained of
water before the air can be removed. This means that
the system is not necessarily vented, despite water
emerging from the safety valve (52) when it is opened
for the first time.
■ Vent the FIGHTER through the safety valve (52).
Other heating systems are vented using their
respective venting screws.
■ Keep topping up and venting until all air has been
removed and the pressure is correct.
Check that the switch (8) is set to ”0”.
Check that valves (44) and (50) are fully open and that
the temperature limiter (6) has not tripped (press the
button firmly).

Preparations
■
The water heater is filled by opening a hot water tap.
When water comes out of the hot water tap this can
be closed.
■ Connect enclosed flexible hose (147) between con-
nection (149) and connection (150). Open filling
valves (151) and (152). The boiler part of the heat
pump and the radiator system are now filled with
water.
■ After a while the pressure gauge (42) will show ris-
ing pressure. When the pressure reaches 2.5 (bar)
(approx. 25 mvp) a mixture of air and water starts
to emerge from the safety valve (52). The filling
valves (151) and (152) are then closed.
■ Turn the safety valve (52) until the boiler pressure
reaches the normal working range (0.5 - 1.5 bar).
■ When the filling procedure is finished the flexible
hose (147) shall be removed.
