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 66]. 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.
NOTICE
When the temperature in multiple rooms is controlled by 1 thermostat, do NOT
