For the Installer
FIGHTER 310P
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 be transported and stored ver-
tically in the dry.
The heat pump contains highly inflammable
refrigerant. Special care should be exercised
during handling, installation, service, clean-
ing and scrapping to avoid damage to the
refrigerant system and in doing so reduce
the risk of leakage.
Transport and storage
Handling
The lifting straps on top of the heat pump should be
removed before starting as these can otherwise cause
increased sound levels. These are removed by first
cutting with a knife and then pulling them out.
Lifting straps
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 high-
est radiator is 5 metres; see figure.
If the standard initial pressure in the
pressure vessel is not high enough it
can be increased by adding 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 pressure affects the ability of
the expansion vessel to handle the expansion of the
water.
The maximum system volume excluding the boiler is
285 litres at the above initial pressure.

Normal temperature levels in boiler or water heat-
er.
The temperature of the hot water in the water heater
may vary between about 50 and 60 °C.
The “Extra hot water” knob (18) on the front panel is
used to increase the hot water capacity.

NOTE!
The transport guard around the compressor
must be removed before starting.

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 bed-
room or other room where noise may be a problem.
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.
An area of approximately 15 cm is required on the left
side of the heat pump, at the temperature and pres-
sure valve (145) to enable access to the valve.
NOTE! Since a waterfilled FIGHTER 310P weighs
roughly 435 kilos, the floor must stand such a weight.
Erecting the heat pump
Normally it is no problem to install FIGHTER 310P in
hard water areas since the maxing working tempera-
ture is 65 °C.
