rotated at all times without the need for dismantling when replacing the Evap cassette.
N.B.! The Evap humidifier must be installed perfectly level!
3. Keep at least 100 millimetres clear space at the bottom.
4. Install the Evap humidifier horizontally between the ducts or air hoses.
The Evap humidifier must hang level to guarantee good water drainage.
5. Use brackets with M8 thread connection to hang the unit.
6. Connect the black 4mm hose with the ¾” adapter to the mains water supply, for this use a ¾” washing
machine tap with check valve.
7. Make sure that the water pressure is between 1.5 bar and max. 3.5 bar.
8. The Evap humidifier is supplied with a 16 millimetres¹ drain hose with a length of 1500 millimetres¹.
