General information for the installer10
FIGHTER 1240
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
and should be documented. The above applies to
closed heating systems. If the heat pump is replaced,
the installation must be inspected again.
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
placing 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 inter-
nal wall that backs on to a bedroom or living room.
Installation
Guideline values for collectors
Inspection of the installation
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.
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 circu-
lation has been established). See Settings, menu.

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, ser-
vice 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.
Electric anode (enamel)
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.
