Risk of injury due to unauthorized connection of the
humidifier to the local water supply system.
– Connecting the humidifier to the local water
supply system may only be done by an author-
ized plumber.
– To ensure a stable function of the water supply,
do not connect to a supply unit with distilled or
treated water.
Connecting the humidifier to the local water supply
system provides risks that can not be assessed by
laymen.
An active water supply is indicated by a running light of
the diodes of the [Indication "Water level"].
The water supply is controlled via the electrode rods of
the water level indicator. For the proper functioning of
the water supply, it is necessary to clean the electrode
rods monthly and remove limescales (
Ä
Chapter 6.3.1
“Monthly cleaning” on page 45).
To prevent over-filling, the device switches automati-
cally off when reaching a fill level of 50 liters (13.2 gal-
lons). Here, an acoustic warning signal sounds and the
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 in spite of the opened solenoid valve,
the operation is canceled and the error code 01
appears on the display.
The following information is directed exclusively to
licensed plumbers that connect the humidifier to the
local water supply system.
Risk of property damage due to excessive water
pressure!
– The maximum water pressure may not exceed 1
MPa (145 psi).
The humidifier can be damaged if the water pres-
sure of the local water supply system is too high.
