It is a matter of experience to determine when the product needs to be cleaned, since the nature
and the degree of pollution depend strongly on the particular situation, humidity, intensity of use,
etc. Nevertheless, the filters should be cleaned regularly (every 1 weeks
up to 4 months).
WARNING
Polluted filters often contain dust and dirt particles that could be a health hazard when inhaled.
When replacing the filter, always wear a reliable and approved facemask.
5.2.1 Removing the filters
Loosen the star knobs and open the door.
Remove the pre filter, ionizer/collector and the after filter (in this sequence).
5.2.2 Cleaning the pre- and after filters
Clean the pre- and after filters in hot water (approx. 60°C) to which a detergent. This treatment
can be repeated several times. Cleaning with a high pressure spraying pistol is also possible..
If the pollution consists of dry dust particles, than the filters can also be cleaned with
compressed air (operating pressure 500-600Pa).
Allow for complete drying after cleaning.
5.2.3 Cleaning of the ioniser/collector
Clean the ioniser and collector in hot water (approx. 60°C) to which a 2% EFC solution has been
added. Cleaning using a high-pressure spraying pistol is also possible.
Check during washing the ioniser for broken ionisation wires. These broken wires can simply be
replaced.
Check during washing the collector for bent lamellas. These can be straightened, carefully, with
a screwdriver. Lamellas in contact with each other can cause short-circuiting.
Allow for complete drying after cleaning.
5.2.4 Mounting the filters
Mount the filters, removed earlier, in reverse order.
.
Note the correct position of the ioniser/collector. For this purpose, filters have arrows indicating the direction of
the airflow. Pay due attention to the position of the contact pin and contact spring.
