Clean the device using a damp cloth, to which you can
apply a little detergent if necessary.
Do not use abrasive detergents and never immerse
the unit in water.
Important
• Ensure that no water penetrates inside the unit!
• Do not put the device or accessories in a dishwasher.
• Do not touch the unit with wet hands while it is
plugged in; do not allow any water to be sprayed
onto the unit. The unit must be operated only when
it is completely dry.
• Do not spray any liquids into the ventilation slots. Any
liquid that penetrates into the unit can damage the
electrical parts or other components of the nebuliser
and impair the function of the device.
Condensation, care of the hose
Depending on the environmental conditions, con-
densation may collect in the hose. To prevent against
bacterial growth and to ensure effective therapeutic
use, this moisture must always be removed. To remove
moisture from the hose, proceed as follows:
• Remove the hose [8] from the atomiser [9].
• Leave the hose plugged into the nebuliser [6].
• Run the nebuliser until all the moisture has been dis-
placed by the flow of air.
• In the event of significant contamination, replace the
hose.
Disinfection
Follow the steps listed below carefully in order to disin-
fect your atomiser and the accessories. It is advisable
to disinfect the individual components after the last
time they are used each day at the latest.
You can disinfect the IH 21 and its accessories in two
ways: using vinegar or boiling water.
First, clean the atomiser and accessories as described
in the "Cleaning" section. Then continue with the dis-
infection.
Disinfection using vinegar
• Use a vinegar solution consisting of ¼ vinegar and ¾
distilled water. Make sure that the volume is sufficient
to fully submerse the parts, such as the atomiser,
mask and mouthpiece, in the solution.
• Leave the parts in the vinegar solution for 30 minutes.
• Then rinse the atomiser and the individual parts such
as the mask and mouthpiece with water.
Disinfection with boiling water
• The atomiser should be taken apart and placed to-
gether with the mouthpiece and nosepiece in boiling
hot water for at least 10 minutes. Avoid the parts
coming into contact with the hot base of the pot.
• You can also disinfect the atomiser, the mouthpiece
and the nosepiece with a standard vaporizer. Ob-
serve the manufacturer's instructions for use for the
vaporizer when doing this.
Note
The face masks and air hose must not be placed in
hot water!
• Carefully dry all components using a soft cloth.
• We recommend disinfecting the masks using a retail
disinfectant.
• Once all components are fully dry, reassemble the
atomiser and place the components in a dry, sealed
container.
Note
Please ensure that the parts are completely dried af-
ter cleaning, otherwise the risk of bacterial growth is
increased.
Drying
• Place the individual components on a dry, clean and
absorbent surface and allow to dry completely (for
at least 4 hours).
Material resistance
• As with all plastic components, frequent use and
cleaning of the atomiser and the accessories can
lead to a certain amount of wear. Over time, this can
alter the aerosol properties and may eventually affect
the efficiency of therapy. We therefore recommend
that you replace the atomiser once a year.
• When choosing a cleaning or disinfecting agent, note
the following: Only use mild cleaning or disinfect-
ant agents in the quantities recommended by the
manufacturer.
Warehousing
• Do not store the nebuliser in a damp atmosphere
(e.g. in the bathroom) or transport it together with
damp objects.
• Store and transport the nebuliser away from direct
sunlight.
Storage
• The accessories can be safely stored in the acces-
sories compartment [4]. Store the device in a dry
place, if possible in its original packaging.
9. Disposal
In the interest of environmental protection, do not dis-
pose of the device in household waste.
Please dispose of the device in accordance with
EC Directive – WEEE (Waste Electrical and Elec-
tronic Equipment).
