General information for the installer

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.

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.

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.
