HR 4325/A
PRODUCT INFORMATION
GENERAL
The HR 4325 is suitable for room / areas with a floor surface of
up to approx. 30 m2.
The air cleaner purifies the air effectively by catching up to 99 %
of the airborne particles.
This is done by 3 filters :
Foam pre-filter : The foam pre-filter catches the larger
dust particles floating in the air, such as
fluff and hairs.
ROTA filter : The ROTA filter takes out the particles
of 2 microns and more (pollen).
HEPA filter HR4920 : This filter takes out all the remaining
smaller particles.
This product meets the requirements regarding
interference suppression on radio and TV.
FEATURES
Filter full indicator: Once the indication light comes on, the
filter has to be replaced. After replacement of the filters, the
filter full indicator has to be reset. The reset button has to be
pressed and hold for at least 3 seconds. The indication light
remains ( or comes ) on. After some time it will go out to
indicate that the indicator has been reset.
Electronic speed setting: 0 - 1 - 2 and turbo.
Safety lock: The front cover has a safety lock.
A nock of the frontcover operates the microswitch of the PCB
when the front cover is closed.
Once the front cover is removed the microswitch interrupts the
electric circuit and the motor stops.
Over heating safety device: The overheating safety device
comes into operation when the motor becomes too hot.
To indicate that the appliance is still in “ ON ” position and
connected to the mains, the pilot light remains on.
If this happens : − Switch off the motor.
− After approx. 15 min. the air cleaner can be
switched on again.
