Low Ambient Option Operation
When the ambient temperature falls to the point that the aftercooler outlet temperature is
approaching 45°F (7°C), the Temperature Control Unit (TCU), mounted on the rear of the
control panel, will automatically adjust the louvers to control the cooling airflow through the
aftercooler.
In the event that the unit is operating under abnormal conditions (very low compressed air
flow) which would cause excessive cooling of the aftercooler, a temperature sensor in the
aftercooler outlet header will signal the TCU to further close the louvers if the compressed air
temperature falls to approximately 36°F (2°C) or lower.
There are no user selectable or serviceable components in the TCU. Contact Ingersoll-Rand
Service if any abnormal operation of the freeze protection control system occurs.
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 the filters are mounted
inside the control panel, and will shut down the compressor if restriction exceeds
recommended values.
Weekly Maintenance:
•
Remove Y-strainer screens at the bottom of the moisture separator and both filters
and clean out any residue.
•
Verify that the orifices below the Y-strainers are not clogged.
•
Verify that the piping from the orifice purge points 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 support inside the front door, and will shut down the compressor if restriction
exceeds recommended values.
Filter Replacement
•
With engine stopped, ensure pressure is relieved from air system.
•
Remove all wires and hoses connected to drains on bottom of each filter housing.
Inspect fittings and hoses for any blockage. Clean if necessary.
•
Using a chain wrench or similar tool, loosen the housing. The housing should be
removed by hand after loosening, taking care to prevent the housing from falling to
the floor panel.
•
Lower the housing to floor panel and lean it against the airend.
