INFORMATION
If you have limited installation space, do the following before installing the unit in its
final position: "7.4.4 To connect the drain hose to the drain" [4 87]. 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.

Because the total refrigerant charge in the system is ≥1.84 kg, the room where you
install the indoor unit must comply with the conditions described in
"7.1.5Installation patterns"[470].
WARNING
▪ Do NOT pierce or burn refrigerant cycle parts.
▪ Do NOT use means to accelerate the defrosting process or to clean the
equipment, other than those recommended by the manufacturer.

ventilated room without continuously operating ignition sources (example: open

size as specified below.

▪ Joints made in installation between parts of refrigerant system shall be accessible
for maintenance purposes.
