NOTICE
We recommend the installation of an Aqua-stop valve in the water supply of the humidifier. In
addition to this, the room, in which the A/C unit with the humidifier is installed, should be equip-
ped with a water detection system.
The steam humidifier is installed and electrically connected in the A/C unit. The local regulations of the water
supply company are to be complied with when making the hydraulic connection.
