The air-conditioner can be completely dismantled.
The air-conditioner can be used between - 30 °C and +
60 °C when installed under standard Central European climatic
conditions.
If
the equipment is installed at special locations (e.g. indoor
pools, bathrooms, in tropical regions), the operational limits
must be ascertained from the manufacturer.
