Page 27-30
• Discard any residual water in the humidifying tray each time you refill the
water tank.
• When using the Air purifying operation only, discard any water in the water
tank and humidifying tray.
• In some cases the air outlet may emit a slight odour as trace amounts of
ozone are generated. However, the amount is negligible and is not harmful
to your health.
• Is the room filled with odours due to cooking or several people
smoking together etc?
¼
The odour will gradually fade as the unit operates.
• Have you moved the unit from another room?
¼
The unit may emit the odour of the room in which it was used previously.
Let the unit run a while longer.
• Is there anything in the room that is emitting an odour continuously?
(Paint, new furniture, wallpaper, sprays, cosmetics, chemicals)
¼
As continuously emitted odour cannot be completely eliminated, you
should ventilate the room at the same time or run the unit in a well-
ventilated room for a short while.
Do not apply deodorising spray or other types of spray to the unit, or
use near the unit.
