User manual Air Purifier
Your HM669A Air Purifier was carefully assembled, packaged, and shipped complete with all the parts you should require.
STEP 1
Before using the air purifier for the first time, open the base and remove both filters. Make sure you altogether remove any packaging from each filter element, or the product will not function correctly.
STEP 2
Plug the output of the power adapter into the connector on the back of the purifier
Plug the power adaptor into an electrical outlet.
The purifier should now be in standby mode.
STEP 3
Push the power button once to turn the air purifier on.
The purifier should now be in operational mode.
The indicator light will be blue and flash for about one second when the power adaptor is first connected to the purifier, indicating the purifier is in standby mode. Press the on/off button once to turn on the device; the indicator light will now be blue; the device will operate in the default mode (sleep) fan speed.
From default mode, press the on/off button repeatedly to cycle through fan speeds:
Sleeping mode (silent speed). The indicator lights are turned off after 5 seconds to enter into sleeping mode. The fan continues to operate at a quieter low speed.
Press the on/off button once to review device mode (after 5 secs the system resumes sleeping mode) or continue to press on/off to cycle through other operational modes.
The filter element lifespan is dependent on how many hours the air purifier is utilized and which mode of operation is used.
The system automatically monitors the fan speed and operational hours, when the filter lifespan reaches 100% that the red indicator light will always be on.
When the filter lifespan reaches 100%, the power indicator will always be bright red when it is on standby or working; when press on/off power button for 3 seconds in standby mode, the red indicator light will be off to complete the reset of filter lifespan.
When the filter lifespan is not up to 100%, if it is necessary to force zero clearing (replace the filter halfway), long pressing the on/off power button for 3 seconds in standby state, the red light will be on, and enter the forced zero clearing mode of filter lifespan; After entering the forced zeroing mode of filter lifespan, long pressing the on/off power button for 3 seconds in standby state, the red light will be off to complete the forced zero.
Note: Total collective hours between filter change = 1000 hrs.
(The 1000 hrs is the filter lifespan of the air purifier at high speed only)
