If there is more than one leaving water zone, ALWAYS install a mixing valve station in
the main zone to decrease (in heating)/increase (in cooling) the leaving water
temperature when the additional zone has demand.
Installation site (see "7.1 Preparing the installation site" [ 4 55] )
WARNING
The appliance shall be stored in a room without continuously operating ignition

WARNING
If the total refrigerant charge in the system is ≥1.84 kg (i.e. if the piping length is
≥27 m)
, you need to comply with the minimum floor area requirements for the
