Inner Charcoal Filter:

The inner charcoal filter will rarely look used. This fil- ter captures odors and gasses, yet the filter’s appear- ance will not change. When this filter has reached it’s maximum adsorbancy of odors and gasses, it will no longer work. Replace this filter when it no longer seems to capture odors, at least every 3 months, whichever occurs first.

Operation

1.Make sure that the unit is plugged into a grounded outlet (120 Volt, 60 Hz).

3.Turn the unit on by pressing the on/off switch to the ‘1’ position. The switch should light up when the unit is on.

4.To turn the unit off, press the on/off switch to the ‘0’ position. The switch light should turn off when the unit is off.
