MAINTENANCE
If you observe the necessary caution and carry out the simple maintenance
and cleaning described below at regular intervals, then any problems will
mostly be detected and corrected before they result in a total breakdown of
the product. The indicated maintenance intervals can vary depending on the
specific working and local conditions. It is therefore recommended that the
product is thoroughly inspected annually in addition to the indicated
periodic maintenance. Please contact your supplier for this purpose.
WARNING
Overdue maintenance can cause fire.
Action
Clean the outside of the product with a mild detergent.
Check the door sealing material.
Clean the inside of the product and remove dust/grease from the filter
compartment.
Clean the pre filter, ioniser, collector and the after filter and check for
damages; see section 9.2.
9.2
Cleaning the pre filter, ioniser, collector and the after filter
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
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, on average, every 2 weeks up to 2 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.
9.2.1 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).
9.2.2 Cleaning the pre and after filters
•
Clean the aluminium 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.
9.2.3 Cleaning of the ioniser and collector
•
Clean the ioniser and collector in hot water (approx. 60°C) to which a
2% Euromate EFC solution has been added. Cleaning using a
high-pressure spraying pistol is also possible.
Euromate EFC is a detergent specially developed for cleaning
electrostatic filter cells. It is available from your supplier.
Always follow the instructions on the packaging.

•
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.
9.2.4 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.
