3.1 Operation Modes

3.1.1 Clean Mode

When the accumulated operation time reach two weeks,The cleaning

indicatorcleaning-indicatorwill be lights up to remind the user to clean the collection array.

Press thefan-speed-press fan speed level button for 3sec to acknowledge the cleaning alert. The cleaning inducator buttton will be turn off.Power off the unit and take out collection array to clean.Clean and dry the collection array before re-install back to the device.

3.1.2 Protection Mode

When the device is operating, and the collection array is removed suddenly, then the device will be stop working, and all indicators will flash at the same time as an alert to user.when the device is powered on without the collection array the device will not work, and all Indicators will flash at the same time as an alert to user. the user needs to shut down the device, and put the collection array into the device, and then the unit will return to nomal operation mode.

3.1.3 Failure Mode

When the collection array accumulates dust anvil or debris and over the collection limit, the device will be stop operation, and all of te lights will flash at the same time as alert to user.The user will need to shut down the device and clean the collection array.

4.Instructions

4.1 connect the power adptor

5 Trouble shooting

Not Operating ,No light indication

-Ensure the collection array is connected with the fan body firmly.

-Ensure the AC adaptor is fully inserted into the AC outlet and its plug is connected to the DC jack of the air purifier.

-Press the Power button momentarily to observe that it’s light up.

Not operating,indicator flashing

-Check the collection array, for too heavy dirt or any clogging by hairs or fibers.

-Clean the collection array as needed and install back ion the air purifier.
