General information for the installer
For the Installer

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
expansion vessel. A new inspection must be made
when changing the heat pump or the expansion ves-
sel.
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
bedroom or other room where noise may be a prob-
lem. 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. If
necessary, for example, with a low ceiling height, it is
possible to position the modules individually.
Route pipes so they are not fixed to an internal wall
that backs on to a bedroom or living room.
FIGHTER 600P has a venting screw located on the
front edge at the top. This should be easily accessible,
which should be considered during installation.
The heat pump should be transported and stored ver-
tically in the dry.
The heat pump contains highly inflam-
mable refrigerant. Special care should
be exercised during handling, installa-
tion, service, cleaning and scrapping to
avoid damage to the refrigerant system
and in doing so reduce the risk of leak-
age.

The volume of the expansion vessel (85) is 10 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.

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 inspec-
tion 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
217 litres at the above initial pressure.
