5. LED DISPLAY (M)
Your air purifier is equipped with a full function LED display which shows the operating status of the unit as
follows:
5.1.
Check Filter Indicator
Your air purifier is equipped with a
CHECK FILTER
indicator to provide a
visual reminder
to check, clean
and replace, if necessary, the filters in your air purifier. The check filer indicator is only a
visual reminder
and not an indicator of the actual condition of the filters. The reminder illuminates continuously in the LED
Display after approximately 3,000 hours (4 months) of operation, and begins to blink after 3,500 hours
lapsed time since its last reset.
5.1.1
‘CHECK FILTER’ Timer Reset
Using the Function Buttons (L) press and hold down both the FAN SPEED and AUTO buttons
simultaneously for about 3 seconds until the unit chimes once and the LED Display briefly flashes “CL" to
confirm you have successfully reset the internal Check Filter timer.
NOTE: This procedure cannot be
performed using the remote control. You must use the buttons on the control panel.
All filters should be checked bi-weekly, cleaned every 3 months and replaced annually for optimal efficiency
and performance. If your indoor air quality is particularly poor or dusty, you may need to check, clean
and/or replace the filters more frequently.

Fan Speed Indicator –

5.3.
AUTO Mode Indicator –

Indoor Air Quality (IAQ) Indicators (Dust & Odor)
The levels of Dust and Odors in the ambient air are shown by the IAQ Indicators in the LED Display. Each IAQ
Indicator operates independent of the other. There are 5 levels of air quality for each indicator and as the presence of
contaminants increases, the number of “wavy” lines shown by the IAQ Indicators will increase. As air quality improves
the number of wavy lines will decrease. The IAQ Indicators will show the air quality as indicated below:
Contaminant Level

Ultraviolet Lamp Status Indicators –
Illuminates to indicate non-functioning UV lamp (UV1 or UV2).
When either the “UV1” or “UV2” icons illuminate, it means that the indicated UV lamp is not working
properly. There are 2 possible causes for this:
1. Either the indicated lamp is not properly seated in its sockets in which case you need to remove and
then reinsert the lamp as indicated in sections 8.4.4 and 8.5.1.
