The filters should be cleaned regularly (every 2 weeks up to 2 months).
The maintenance activities in the table below indicated by [1] can be carried out by the user; other activities are strictly reserved for qualified personnel.
Cleaning instructions:
1.- Removing the filters
Switch off the unit by turning the main switch (fig. 4A).
Loosen the star knobs and open the door
Remove the pre filter, ioniser, collector and the after filter (in this sequence).
2.- Cleaning the pre and after filters
Clean the pre and after filters in hot water (approx. 60°C) added with a detergent for domestic use. This treatment can be repeated several times. Cleaning with a high-pressure spraying pistol is also possible.
Allow for complete drying after cleaning.
3.- Cleaning of the ioniser and collector (Use a detergent specially developed specially developed for electrostatic cleaners.)
Clean the ioniser and collector in hot water (approx. 60°C) to which a 2% Plymovent EFC solution has been added. Cleaning using a high-pressure spraying pistol is also possible.
Check the ioniser during washing for broken ionisation wires. These broken wires can simply be replaced.
Check the collector during washing for bent lamellas. These can be carefully straightened with a screwdriver. Lamellas in contact with each other can cause short-circuiting.
Allow for complete drying after cleaning.
4.- Mounting the filters
Mount the filters, removed earlier, in reverse order.
Note the correct position of the ioniser and collector. For this purpose, both filters have arrows indicating the direction of the airflow. Pay due attention to the position of the contact pin and contact spring.
Clean or replace the filters:
when damaged
when the ioniser and/or collector starts to make a crackling sound (indicator starts blinking or stops being lit)
when the extraction capacity becomes inadequate
