Replacement of the demineralization
cartridge
Always unplug the unit before removing the
water tank. Do not touch the water in the base
during operation!
The water tank is equipped with a demineralization cart-
ridge. This cartridge has to be replaced every 2 – 3 months.
If the water is very hard, it may be necessary to replace the
cartridge earlier. White dust around the device is a sure sign
that the cartridge needs replacing. If white residue still forms
around the device after a new cartridge has been inserted,
please make sure that the water you are using is untreated.
If the water flows through a decalcification system – such as
an ion exchanger – (sodium is added to remove calcium) in
the building before it is used in the humidifier, salt can pre-
cipitate as white dust around the device. The demineralization
cartridge or the granules must be exchanged at the latest
after 6 months or the unit does not reach its full performance
anymore.
Option A: replace the granules
• Remove the water tank from the base and unscrew the
water tank cap (30).
• The demineralization cartridge is attached to the tank
cap. Unscrew the cartridge from the cap by turning it
counter-clockwise (31). Important: do NOT dispose of
the water tank cap!
• Open the cartridge (32).
• Throw the content into the waste (Attention! Disposed
granules can make the floor slippery!) (33).
• Place the enclosed pink styrofoam piece in the center
of the cartridge. Do not push it to the bottom as it will
be difficult to remove afterwards (34).
• Pour the contents of one refill granules bag into the
plastic cup that is included with the refill granules
packaging (35).
• Place the empty cartridge with the plug in the center
onto the plastic cup (36).

• Turn the plastic cup and cartridge over and shake until
all granules are in the cartridge (37).
• Remove the plastic cup and the pink styrofoam piece
from the cartridge (38) and retain for future use (the
refill granules consists of 3 refill bags) (39).
• Close the cartridge (40).
• Soak the demineralization cartridge in a water bath
24 hours before using it (43). The granules have to
absorb water to reach maximum performance. If the
cartridge is soaked in the tank, make sure to exchange
the water and empty the water from the base before
using the humidifier.
• Screw the cartridge on the water tank cap (44).
• Screw the cartridge on the bottom side of the water
tank, put the tank on the main body (45).
Placing granules in the center of the cartridge
allows them to escape in the unit or to clog the
unit. The unit will no longer operate properly and
the granules need to be cleaned out thoroughly.
Option B: replace the whole cartridge
• Remove the water tank from the base and unscrew the
water tank cap (30).
• The demineralization cartridge is attached to the tank
cap. Unscrew the cartridge from the cap by turning it
counter-clockwise (31). Important: do NOT dispose of
the water tank cap!
• Throw the whole cartridge into the waste (41).
• Unpack the new cartridge (42).
• Soak the demineralization cartridge in a water bath
24 hours before using it (43). The granules have to
absorb water to reach maximum performance. If the
cartridge is soaked in the tank, make sure to exchange
the water and empty the water from the base before
using the humidifier.
• Screw the cartridge on the water tank cap (44). Close
tank cap well and place the tank on the main body
(45).
