Additionally to the spacing guidelines: Because the total refrigerant charge in the
system is ≥1.84 kg, the room where you install the indoor unit must also comply
with the conditions described in "7.1.3Installation patterns"[431].
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 where frost is possible. Ambient temperature around the indoor unit
must be >5°C.
