The spark arrester and the final filter can be cleaned in different
ways:
- in hot water (approx. 60°C) to which a detergent for domestic
use has been added. This treatment can be repeated several
times; or
- using a high-pressure cleaner; or
- if the saturation consists of dry dust particles: by compressed
air (operating pressure 500-600 kPa).
• Clean the spark arrester and the final filter.
• Let both filters dry thoroughly.

The ioniser and the collector can be cleaned in different ways:
- in hot water (approx. 60°C) to which a solution of 2% EFC has
been added (preferred way); or
- using a high pressure cleaner
EFC is a detergent which has been specially developed
for cleaning electrostatic filter cells. It is available from
your supplier. Always follow the instructions on the
packaging and use a paint brush, especially for the
ioniser.
• Clean the ioniser and the collector.
• Let both filter sections dry thoroughly.
• Check the ioniser for broken ionisation wires. Replace broken
wires.

lamellas carefully using a screwdriver.
