If the dehumidifier works in a room with open doors or windows, the humid air will keep coming in to offset the work of the dehumidifier. 2) The optimum temperature of working for this dehumidifier is 59?~104? / 15?~40?. It will achieve good dehumidification at around 86?. You will not see obvious dehumidification effect, when the room temperature is lower than 59?/15?. 3) The optimum relative humidity of working for this dehumidifier is 45%RH~80%RH. It will achieve very good dehumidification at around 80%RH. You will not see obvious dehumidification effect, when the relative humidity is lower than 45%RH. 4) The dehumidifier is suitable for Maximum 300 Square . To be frankly, this semi-conductor dehumidifier will NOT be as efficient as compressor dehumidifiers. When in big space, the dehumidification can be slow and not that obvious. To quicken the dehumidification, you can use 2 or 3 units together in the same room. 5) Humid air will be sucked into the machine from the "air inlet" part and will go out from "air outlet" part, after being dried. Therefore, pls never block the "air inlet" and "air outlet" . 6) Pls keep the dehumidifier with a minimum distance of 20CM to any wall, cabinet wall, etc., to make sure good air flow around the dehumidifier. 7) We suggest putting the dehumidifier a flat table. 8) In dry seasons when you do NOT use this dehumidifier, you can clean and dry the water and then cover this dehumidifier with a plastic bag to protect it from dust. /OFF button: Night Light button: 1st press to turn the light and the light color will change gradually automatically. 2nd press to choose the light color you like. 3rd press to turn off the night light completely.
