Indicators
Main Power on Light
Indicates when power from the main disconnect switch
has been turned on and there is live power at the com-
pressor 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 separa-
tor 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 mix-
ture 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 indica-
tion of the amount of air being used.
