Replacement of the demineralisation
cartridge
Always switch off the appliance before removing
the water tank. Do not reach inside the nebuliser
en
space while the appliance is running!
The cartridge must be replaced every 2 – 3 months. If the
water is very hard, it may be necessary to replace the cart-
ridge earlier. White dust around the appliance is a sure sign
that the cartridge needs replacing. If white residues con-
tinues to form around the appliance after a new cartridge
has been inserted, please make sure that the water you are
using is untreated. If the water flows through a domestic
decalcification system before it is used in the unit, salt will
precipitate around the appliance.
Option A: Replace the granules
• Remove the water tank from the base and unscrew the
water tank cap (25).
• The demineralisation cartridge is attached to the inside
of the cap. Unscrew the cartridge from the cap by
turning it counter-clockwise (26). Important: do NOT
dispose of the tank cap!
• Open the cartridge (27).
• Throw the content (granules) into the waste (28). Atten-
tion! Disposed granules can make the floor slippery!
• 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 (29).
• Pour the contents of one refill resin bag into the plastic
cup that is included with the refill resin packaging (30).
• Place the empty cartridge with the plug in the center
onto the plastic cup (31).
• Turn the plastic cup and cartridge over and shake until
26
all granules are in the cartridge (32).
• Remove the plastic cup and the pink styrofoam piece
from the cartridge (33) and retain for future use (the
refill resin consists of 3 refill bags) (34).
• Close the cap (35).
• Soak the demineralisation cartridge in a bowl of water
for at least 24 hours before use (38). The granules have
to absorb water to reach full performance.
• Now screw the cartridge onto the water tank cap (39).
Close the tank cap securely! Place the water tank onto
the base (40).
Option B: Replace the entire cartridge
• Remove the water tank from the base and unscrew the
water tank cap (25).

of the tank cap. Unscrew the cartridge from the cap by
turning it counter-clockwise (26). Important: do NOT
dispose of the tank cap!
• Dispose of the old cartridge (36).
• Unpack the new cartridge (37).
• Soak the new cartridge in a bowl of water for at least
24 hours before use (38). The granules have to absorb
water to reach full performance.
