5.1 GENERAL

While Sullair has built into this compressor a com-
prehensive array of controls and indicators to
assure you that it is operating properly, you will
want to recognize and interpret the reading which

will call for service or indicate the beginning of a
malfunction. Before starting your Sullair compres-
sor, read this section thoroughly and familiarize
yourself with the controls and indicators - their pur-
pose, location and use.
PURPOSE
Depress to turn the compressor ON.
Depress to turn the compressor OFF.
Records cumulative hours of compressor operation; useful
for planning and logging service schedules.
Continually monitors service line air pressure. Located on
dry side of receiver downstream from check valve.
Continually monitors receiver/sump pressure at various load
and/or unloaded conditions.
Monitors temperature of the air leaving the compressor unit.
For both air and water-cooled compressors, the normal
reading should be approximately 180ºF to 205ºF (82ºC to
96ºC ) for ambient temperatures up to 105° F.
Indicates when a fluid filter element change is required. It
shows red when the pressure drop through the filter is
excessive.
Indicates when separator element change is required. It
shows red when pressure drop through the separator is
excessive.
Indicates when the starter is energized.
Indicates when compressor is in operation.
Monitors fluid level in the sump. Proper level should fill the
sight glass. Check the level when the compressor is shut
down. DO NOT OVERFILL.
Used to indicate fluid flow in the return lines. When the
compressor is running at full load, fluid flow should be visi-
ble in these sight glasses. There may be little or no flow
when the compressor is running unloaded, but a sluggish
flow at full load indicates a need to clean the return line
strainers.
Cuts off flow of fluid to compressor unit at compressor shut-
down and allows flow of fluid to the unit on start-up.
Cuts off the reverse flow of air/fluid mixture through com-
pressor discharge system at compressor shutdown.
