ELECTRONIC FILTER CLEAN REMINDER

This model air purifier has an electronic filter check to remind you when to check and clean the washable IFD™ filter based on the air purifier's hours of use.

When the IFD™ filters need to be cleaned, the light will remain on until it is RESET. You may unplug the air cleaner without interrupting the filter check.

A red LED light will illuminate when it is time to clean the filter.

You should periodically check the filter. Depending on operating conditions, the filters should be cleaned at least once a month.

To RESET the Electronic Filter Check:

Fig. 3

When the filter monitor light remains on, it is time to check/clean the IFD™ filters and reset the filter monitor, if needed. With the unit powered on, insert the tip of a ball-point pen or paperclip next to the LED filter check light and hold for approximately 5 seconds until the light turns off (Fig. 3). Depending upon your individual usage (environment and hours used), you may need to check and clean the filters more or less frequently. If the IFD™ filters are cleaned before the filter monitor light turns on, the filter monitor should be reset at the same time.

These cleaning intervals are intended as guidelines only. Performance of any filter media is dependent upon the concentration of contaminates going through the system. High concentrations of contaminates such as dust, pet dander and smoking will reduce the useful performance of the filter.

OSCILLATION FEATURE

•To turn Oscillation on, simply press the Oscillation button ( ) (Fig. 4).
