For the Installer
FIGHTER 1220
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 1220 is placed on a firm base, preferably a
concrete floor or foundation. Install FIGHTER 1220
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. Irrespec-
tive of the placement the wall should be sound insulat-
ed. Route pipes so they are not fixed to an internal
wall that backs on to a bedroom or living room.
The FIGHTER 1220 must be transported and stored
upright and dry. The FIGHTER 1220 may however be
carefully laid on its back when being moved into a
building.

Inspection of the installation
The unit can be used exclusively as an electric boiler,
to produce heat and hot water, for example before the
collector installation is complete. For this mode, the
hot water temperature is preset to 50 °C. See Set-
tings, menu 9.2.4.
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.
9.2.12.
Electric boiler mode
FIGHTER 1220 is equipped with an electric anode to
protect the enamelled hot water heater. The electric
anode works automatically when FIGHTER 1220 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.

Guideline values for collectors
For use with 40 x 2.4 PN 6.3 PEM hose.
The length of the collector hose varies depending
on the rock /ground conditions and on the heating
system, i.e. radiators or floor heating.
Max length per collector should not exceed 400m.
Where there is more than one collector, they must be
connected in parallel, with a means of adjusting the
flow.
The hose should be buried at a depth of about 1 metre
and the distance between the hoses should be at least
1 metre.
For several bore holes, the distance between the
holes must be at least 15m.
