ABOUT HUMIDIFIER
A humidifier is a device that increases humidity in a room. A Comfortable
Indoor atmosphere is achieved at a relative humidity of between 40 and 60%.
It acts as a moisturising agent by relieving dryness and maintaining a level of
comfort during dry winters.
Your appliance automatically controls the humidity level according to your
chosen setting. If the air is too dry, the unit will automatically switch on. As
soon as the desired humidity level is reached, it will automatically switch off.
Excessively low humidity can cause health problems such as dry throats and
noses, chapped lips and other respiratory diseases. Low humidity can also
affect wooden furniture and carpets, causing shrinkage and loose joints. Books
and paper may also shrink, warp and become increasingly brittle.
Benefits of Humidification:
1) Rooms stay clean and germ-free.
2) Makes indoor air more pleasant and comfortable.
3) Ultrafine water particles prevent books, wallpapers and carpets from getting
wet and mouldy.
4) Prevents drying out of mucous membrane, chapped lips and stinging eyes.

For safety purpose you should read the instructions carefully before using the appliance for the first
time and follow them. Save the instructions for future reference.

PRODUCT DETAILS

DEMINERALIZATION CATRIDGE
Your humidifier is not designed for water which has passed through a water softener which
uses a salt. The humidifier’s de-calcification cartridge cannot absorb the salt which results in
a white precipitate forming inside the appliance. If a white precipitate should form anyway,
the capacity of the de-calcification cartridge has been exhausted. This can occur sooner or
later depending on the hardness of the water. In this case, please replace the de-calcification
cartridge.
We recommend that you do not use the appliance if your water hardness is near 100 TDS.
Soak the de-calcification cartridge in a water bath 1 hour before the first use; the granules
have to absorb water to reach high performance.
