Operating & Maintenance Manual Operating Instructions
48
If the IQ System is bypassed (Standard Operation selected), the delivered air pressure will be
approximately equal to the separator tank pressure. If the IQ System operation is selected, the
delivered air pressure will be slightly less, depending on the restriction of the filters.
CAUTION
!
The compressor regulation system is adjusted to maintain regulated
pressure at the separator tank. DO NOT adjust regulation to provide full
regulation pressure at the service valve when the IQ System is enabled.
This will result in operation at excessive horsepower levels, causing
overheating, reduced engine life, and reduced airend life.
Low Ambient Option Operation
When the ambient temperature falls to the point that the aftercooler outlet temperature is
approaching 45° F, 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 (i.e., an enclosure door open)
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 36º F or lower.
There are no user selectable or serviceable components in the TCU. Contact Portable Power
Service if any abnormal operation of the freeze protection control system occurs.
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.
CAUTION
!
Excessively restricted filter elements may cause an increase in the
amount of aerosol water and oil carryover, which could result in damage
to downstream equipment. Normal service intervals should not be
exceeded.
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.
