Cleaning the primary element
WARNING
Flying debris!
Compressed air can propel dirt, rust, etc. into
the air. Wear eye and face protection when
using compressed air.
Failure to comply could result in death or se-
rious injury.
If the primary element is dry:
Blow compressed air from the inside towards the outside
at very low pressure. The compressed air nozzle should
be held at least 3 cm from the inside wall of the element.
Cleaning is completed once no more dust comes out of
the primary element.
ATTENTION: Compressed air pressure should not ex-
ceed 7 bar.
ATTENTION: Do not use compressed air if there is oil or
soot in the element.
If the cartridge is greasy:
Clean it in water with a suitable detergent (consult your
CASE CONSTRUCTION Dealer). Instructions for using
the detergent are printed on the packaging.
NOTE: Allow the element to dry completely before in-
stalling it. It is advisable to keep a spare, clean element
ready for installation on the air filter while the cleaned el-
ement is drying.
