Always observe the following safety instructions and regulations.
Application guidelines (see "6 Application guidelines" [
4
28] )
CAUTION
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
sources (example: open flames, an operating gas appliance or an operating electric
heater).
WARNING
DO NOT reuse refrigerant piping that has been used with any other refrigerant.
Replace the refrigerant pipes or clean thoroughly.
WARNING
▪
Do NOT pierce or burn.
▪
Do NOT use means to accelerate the defrosting process or to clean the
equipment, other than those recommended by the manufacturer.
▪
Be aware that R32 refrigerant does NOT contain an odour.
WARNING
The appliance shall be stored so as to prevent mechanical damage and in a well-
ventilated room without continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric heater) and have a room
size as specified below.
Charging refrigerant (see "8.5 Charging refrigerant" [
4
91] )
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
indoor unit. For more information, see "7.1.3 Installation site requirements of the
indoor unit" [

CAUTION
To avoid compressor breakdown, do NOT charge more than the specified amount of
refrigerant.
WARNING
▪
Only use R32 as refrigerant. Other substances may cause explosions and
accidents.
▪
R32 contains fluorinated greenhouse gases. Its global warming potential (GWP)
value is 675. Do NOT vent these gases into the atmosphere.
▪
When charging refrigerant, ALWAYS use protective gloves and safety glasses.
