To prevent overfilling, the device switches off automatically upon
reaching a fill level of 50 liters (13.2 gallons). Here, an acoustic
warning signal sounds and error code 04 appears on the display. If
there is a defect in the water supply and the water level does not
change after 10 minutes despite the solenoid valve being open, the
operation is cancelled and error code 01 appears on the display.
The following information is directed exclusively to
licensed plumbers who connect the humidifier to the
local water supply system.
NOTICE!
