Transport and storage

The FIGHTER 1240 must be transported and stored
upright and dry. The FIGHTER 1240 may however
be carefully laid on its back when being moved into a
building.

Installation

FIGHTER 1240 is placed on a firm base, preferably
a concrete floor or foundation. Install FIGHTER 1240
with its back to an outside wall, ideally in a room where
noise does not matter. If this is not possible, avoid plac-
ing it against a wall behind a bedroom or other room
where noise may be a problem. Any wall that backs on
to a bedroom should be fitted with sound insulation.
Route pipes so they are not fixed to an internal wall
that backs on to a bedroom or living room.

Guideline values for collectors

Type Surface soil heat,
recommended
collector length
5 200 – 300 m
8 325 – 2x250 m
12 2x250 – 2x350 m
For use with 40 x 2.4 PN 6.3 PEM hose.
The length of the collector hose varies depending
on the rock /soil conditions and on the heating sys-
tem, i.e. radiators or floor heating.
Max length per collector should not exceed 400 m.
Where there is more than one collector, they must be
connected in parallel, with a means of adjusting the
flow.
For surface soil heat, the hose should be buried at a
depth of about 1 metre and the distance between the
hoses should be at least 1 metres.
For several bore holes, the distance between the holes
must be at least 15m.

Inspection of the installation

Current regulations require the heating installation to
be inspected before it is commissioned. The inspec-
tion must be carried out by a suitably qualified per-
son and should be documented. The above applies to
closed heating systems. If the heat pump is replaced,
the installation must be inspected again.
Additional heat only (electric
FIGHTER 1240 can be used with only additional heat
(electric boiler) to produce heating and hot water, for
example, before the collector installation is complete.
See menu 9.2.4. NOTE! Select Off to deactivate
only additional heat and select the required oper-
ating mode using the operating mode button.
The brine pump normally follows the operation of
the heat pump. There is a special operating mode for
continuous operation for 10 days, followed by return
to normal mode (this may be used before stable cir-
culation has been established). See Settings, menu.
9.2.12.

Electric anode (enamel)

FIGHTER 1240 is equipped with an electric anode to
protect the enamelled hot water heater. The electric
anode works automatically when FIGHTER 1240 is
switched on and is positioned behind the lower, serv-
ice cover.
■ A green LED on the transformer indicates that the
electric anode is operational.
■ When the LED is not lit the anode is not receiving
power; call the installer when this can not be recti-
fied.
■ When the LED flashes red, contact the installer.

Hard water areas

Normally it is no problem to install FIGHTER 1240 in
hard water areas since the maxing working tempera-
ture is 60 °C.
