Operation
HEPA FILTER REPLACEMENT
In order to maintain the best air purification effect, this device will tell you when the HEPA
filter is in need of replacement. The red indicator replacement filter light (as shown on page 8)
will begin to flash when the filter needs to be replaced. If you want this logo to stop flashing,
press and hold the AI PURIFICATION button for three seconds.
CHILD LOCK
Press and hold both the INCREASE TIMER and DECRESE TIMER buttons for three seconds
to place the unit in CHILD LOCK state. In this state, all buttons will be invalid and the fan will
stay in the desired mode set before child lock. To release CHILD LOCK, press and hold the
INCREASE TIMER and DECREASE TIMER buttons for another three seconds.
Other Functions
POWER MEMORY
If it is not the first time the fan has been switched on, it will remember the mode it was running
in (except for the timer) before it was switched off. After you press the ON/OFF button
to switch the device on, it will automatically start to run in the state it was on previous to
switching off.
AUTOMATIC SHUTDOWN
If there is no timer set, the device will automatically shut down after 15 hours of continuous
use.
