Monitoring Operation
You can always monitor the quality of room air, and make sure that the Purifier is set to move a volume of air appropriate for
present conditions. Note that measurements are relative to the selected room size. Make sure that the “Room Size” panel is
always set for the room in which the unit operates. “Quality” and “Volume” are shown on the Information display.
Air quality is sensed by the chemical-detection sensor (see figure 1) which continually
evaluates air quality. Air quality is expressed by one of five lights expressing a range
from GOOD to POOR.
Air volume is shown by one of seven lights (figure 4) representing a range from greater than
normal air flow, to reduced air flow (energy-saving Sleep Economy Mode). The light shows
that air volume is just right for the selected room size.
You should also keep an eye on the Service Panel which tells you if maintenance will soon
be required, or if maintenance is required for further operation. The Service Panel is described
in Maintaining the EnviroMade APS 2000.
