compressor starter and control panel. This light will
remain on as long as there is power to the unit, regardless
of the position of the selector switch.
CAUTION!
Always check power supply disconnect. The
Power-on light may be inoperable.
High Discharge Air Temperature Light
Indicates when the unit has sensed an unusually high
discharge temperature.
Fluid Filter Change Light
Indicates excessive pressure differential across the fluid
filter. It is used to determine fluid filter change intervals.
Air/Fluid Separator Element Differential Light
This indicates excessive pressure differential across the
air/fluid separator element. It is used to determine
separator element change intervals.
Air Intake Filter Service Light
This indicator signals when the filter element needs to be
cleaned or replaced.

Gauges

Hourmeter
This gauge indicates actual hours of operation.
Air Pressure Gauge
This gauge indicates air pressure available for
distribution to the service line.
Gauge may not register when the unit is unloaded
or off. Make certain all air pressure is relieved
prior to servicing.
Air Outlet Temperature Gauge
This gauge indicates the temperature of the air/fluid
mixture as it discharges from the compressor. The
normal reading is 170-190°F.
Percent Capacity Gauge
This gauge is graduated in percent of the total capacity of
the unit. Readings taken from this gauge give an
indication of the amount of air being used.
