In any case, provide at least 300 mm of free space below the unit.
Additionally, make sure the unit is positioned at least 100 mm above
the maximum expected level of snow. See
"7.3 Mounting the
outdoor unit" on page 31
for more details.
In heavy snowfall areas it is very important to select an installation
site where the snow will NOT affect the unit. If lateral snowfall is
possible, make sure that the heat exchanger coil is NOT affected by
the snow. If necessary, install a snow cover or shed and a pedestal.

Installation site requirements of the
indoor unit
INFORMATION
Also read the precautions and requirements in the
"General safety precautions" chapter.
▪ The indoor unit is designed for indoor installation only and for the
following ambient temperatures:
▪ Space heating operation: 5~30°C
▪ Space cooling operation: 5~35°C
▪ Domestic hot water production: 5~35°C
▪ Mind the following measurements guidelines:
Maximum refrigerant piping length between indoor
unit and outdoor unit
30 m
Minimum refrigerant piping length between indoor
unit and outdoor unit
3 m
Maximum height difference between indoor unit and
outdoor unit
20 m
▪ Mind the following spacing installation guidelines:
≥
300
≥600
≥
500
(mm)
INFORMATION
If you have limited installation space, do the following
before installing the unit in its final position:
"7.8.5 To
connect the drain hose to the drain" on page 40
. It
requires to remove one or both side panels.
▪ The foundation must be strong enough to bear the weight of the
unit. Take the weight of the unit with a domestic hot water tank full
of water into account.
Make sure, in the event of a water leak, water cannot cause any
damage to the installation space and surroundings.
Do NOT install the unit in places such as:
▪ In places where a mineral oil mist, spray or vapour may be
present in the atmosphere. Plastic parts may deteriorate and fall
off or cause water leakage.
▪ Sound sensitive areas (e.g. near a bedroom), so that the
operation noise will cause no trouble.
▪ In places with high humidity (max. RH=85%), for example a
bathroom.
▪ In places where frost is possible. Ambient temperature around the
indoor unit must be >5°C.
Special requirements for R32
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.
