PRODUCT INFORMATION

GENERAL

The HR 4320 is suitable for rooms / areas with a floor surface of

The aircleaner 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 (e.g. pollen).

HEPA filter HR4920 : This filter takes out all the remaining

smaller particles.

Product meets the requirements regarding interference
suppression on radio and T.V.

FEATURES

Filter full indicator: Indicates that the filter has to be

replaced. This has to be done when the white part of the
indicator has turned pink like the other (pink) half.

Speed control: With 3 speed settings.

Safety lock: Prevents the customer from opening the front

cover whilst the air cleaner is switched on.
The front cover can only be opened, if the switch has been set to
the “0" position.

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.
