Timer function
The air purifier has a timer function with which
you can decide on the number of hours after
which the device must stop. The air purifier has
three timer periods: 2HRS (two hours), 4HRS
(four hours) and 8HRS (eight hours).
To move from one timer speed to another, press
the timer button. The timer length indicator as
currently configured will light up on the con-
trol panel. The air purifier then switches off au-
tomatically after the number of hours defined.
To switch off the timer, press the timer button
until no light is lit above the button. The air pu-
rifier will then run with no time limit.
