Maintenance plan
6.2
Maintenance of the main filter
element
Maintenance of the main filter
element (Pos. 2) need only be
performed when the maintenance
indicator/switch has been triggered
or according to the device or engine
manufacturer's instructions.
Regardless of the number of
operating hours, the main filter
element must be changed after 2
years at the latest.
Never continue to use damaged
main filter elements.
In case of doubt, always install a
new main filter element.
6.2.1
Disassembling the main filter
element
Unlock the wire clamp fasteners (Pos. 9)
and remove the housing cover (Pos. 1).
Remove the main filter element (Pos. 2) and
dispose of it according to local regulations.
Clean the inside of the housing, frame and
lid thoroughly with a damp cloth. In the case
of filters without a secondary element, pay
particular attention here that no dust or dirt
gets into the clean air side of the filter.
Check all the parts for signs of damage and
wear, replace them as necessary.
IQORON series 10, 12 and 14:
Move the red clamping bar towards
"Unlock" (refer to Fig. 4).
Remove the frame (Pos. 11) together with
the main filter element (Pos. 2).
Remove the main filter element from the
frame and dispose of it according to the
local regulations.
6.2.2
Cleaning the main filter element
Never wash out or beat the main
filter element.
When blowing clean, ensure no
dust gets into the inside of the main
filter element.
Since small defects are difficult to
detect or cannot be detected, we
recommend always installing new
elements to protect engines or
equipment!
We assume no liability for the
suitability of cleaned elements.
Clean
the
main
filter
element
with
compressed air (maximum 5 bar) carefully,
applying the compressed air from the clean
side (seal side) until no more dust
development occurs. The tip of the
compressed air gun must not touch the
main filter element.
