3. Setting the fan speed and air volume to the correct room size.
Press the ”Fan Speed Button” (gure 1) until the green LED bar light underneath ”Room Size/Fan Speed”
reaches the corresponding size of your room. Calculations in both ”square feet” and ”square meters”
(length x width) measurements are conveniently listed at either side of the green LED bar lights. Correctly
setting this indicator will keep the air volume at an optimum level.
To achieve faster air purication, the fan speed can be increased to the maximum level.
4. Press the ”Sleep Mode Button” (gure 1) at night if you desire to reduce fan noise.
A green LED light will illuminate to the right side of the button indicating Sleep Mode. This will maintain
constant airow through the purier and reduce fan speed to a minimum. Since there is no movement in the
room, purication requirements are greatly reduced.
Press the Sleep Mode Button again to return to the normal air ow mode.
MONITORING OPERATION
You can always monitor the air quality of the room.
Air quality (level of VOCs) is sensed in real time by the chemical-detection sensor (see gure 1 on page 4)
which continually evaluates air quality. Air quality is expressed by one of (3) colors on the air quality LED light.
1. Green indicates good air quality.
2. Orange indicates moderate air quality.
3. Red indicates poor air quality.
Air volume is automatically increased by (2) fan speed levels when the air quality indicator turns red,
and will reset to a preset fan speed when the air quality indicator turns orange and then green.
It is normal for the air quality indicator to temporarily be red during periods of house cleaning, painting, or
cooking meals.
COMPREHENDING INDICATOR LIGHTS ON THE SERVICE PANEL
You should also keep an eye on the Service Panel which tells you when maintenance will soon be required.
Indicator lights on the Service Panel (“Air Filter” and “UV Lamp”) tell you if either the air lters or the
germicidal ultraviolet lamp will soon need to be cleaned or replaced.
