Installation
General information for the installer
Transport and storage
The air treatment section and water heater must be
transported and stored upright and dry.
Installation/Suspension
The air treatment section and water heater are installed
near floor drains, free standing (minimum 10 mm from
walls) and with the back against an outside wall in a
utility room or similar type of room to minimise any
noise nuisance. If it is not possible to mount the heat
pump against an outside wall avoid a wall connecting
to a bedroom or living-room.
The water heater is installed standing on the floor.
Route pipework so it is not fixed to an internal wall that
backs on to a bedroom or living room.
The air treatment section can either be hung on a wall,
using the supplied plastic mountings, or fasten with
screw on brackets. When suspending on the plastic
mountings, first install the mountings on the wall as
illustrated below, then hang the air treatment section
up.Then screw the unit to the wall via the lower mount-
ings (see image below).
NOTE!
Check that the mountings are located in
their applicable grooves on the air treat-
ment section.
Ensure that the air treatment unit is
installed horizontally.

Alternative connection installation
The ventilations connections on FIGHTER 120 can be
installed partially upwards (factory installed,) partially
laterally. Due to limited space where it is difficult to
connect the ventilation ducts, the connections can be
made from the side. To facilitate servicing, however, it
is recommended to leave 20 – 30 cm above the heat
pump, as the fan and electronics are serviced most eas-
ily from above.
Refrigerant system
All work in and around the cooling circuit must be car-
ried out by an authorised refrigeration technician.
Calcium
When FIGHTER 120 circulates and heats up fresh water,
calcium and other minerals can affect the components'
(condenser, valves and circulation pump) cleaning cycle/
service life. If FIGHTER 120 is installed in calcium hard
water areas, some form of descaler should be installed
in the system.
NOTE!
The heat pump's switch (8) must not be
moved to position 1 until the water heater
has been filled. Otherwise there is a risk of
damaging the heat pump's components.
