5.6 Air inlet filter
The blockage indicator is designed to show/hold the maximum inlet
blockage encountered. It is set to show 100% blockage when the inlet
depression reaches 50mbar.
If the indicator valve has entered the red portion of the scale (when
the compressor is operating), the filter must be cleaned or replaced by
employing one or both of the following processes:
Remove accumulated filter debris (machine not running)
1.
Pull back the clips retaining the air inlet filter end cap and remove the
end cap.
2.
Empty out any dust or dirt and clean out the main filter cavity.
Replace the end cap the correct way up and re-clip in position.
Clean the filter element
To clean the filter element (machine not running):
1.
Remove the air filter end cap (as described in the previous section).
2.
Withdraw the filter from the filter body.
3.
Clean the filter by blowing compressed air through the inside of the
element.
4.
Element replacement is a direct reversal of the above.
Filter elements should be replaced every 12 months or sooner if cleaning
does not return the blockage indicator to the unblocked condition.
