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"
▪
The foundation must be strong enough to bear the weight of the unit. Take the
weight of the unit with a storage 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.
▪
The foundation must be level and smooth.
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.
▪
In places where the unit is exposed to direct sunlight for long periods of time.
Extensive UV radiation can damage the unit.
