MAINTENANCE
Daily maintenance:
Verify, during full–load (maximum compressed air delivery) that
the IQ system filter restriction indicators do not show excessive
restriction.
Restriction indicators for primary and secondary filters are
located on the filter heads. If so equipped, an automatic
restriction indicator is located behind the filter mounting bracket
and will shut down the compressor if restriction exceeds
recommended values.
Weekly Maintenance:
S Verify that the piping from the water separator and filters to
the exhaust system is not clogged.
Yearly Maintenance:
The normal maintenance interval on the primary and secondary
IQ System filters is one year, or earlier if pressure drop becomes
excessive.
Restriction indicators for the filters are mounted on the filter
heads. If so equipped, an automatic restriction indicator located
behind the filters will shut down the compressor if restriction
exceeds recommended values.

housing should be removed by hand after loosening, taking care
to prevent the housing from falling to the floor panel.
