Rupture Disk; General; Purpose Of Controls - Sullair VS-32 Operator's Manual

5.1 GENERAL

While Sullair has built into this Vacuum System a
comprehensive array of controls and indicators to
assure you that it is operating properly, you will
want to recognize and interpret the readings which

will call for service or indicate the beginning of a
malfunction. Before starting your Sullair Vacuum
System, read this section thoroughly and familiarize
yourself with the controls and indicators - their pur-
pose, location and use.
PURPOSE
Depress to turn the Vacuum System ON.
Depress to turn the Vacuum System OFF.
Records cumulative hours of Vacuum System opera-
tion. Useful for planning and logging service sched-
ules.
Continually monitors system vacuum.
Continually monitors vacuum unit inlet vacuum via vac-
uum gauge. Along with the system vacuum reading,
indicates air filter condition for maintenance purposes.
Monitors temperature of vacuum unit gas/fluid dis-
charge. Normal reading is approximately 180ºF (82ºC)
with ambient temperatures of 80ºF (27ºC) or less.
Indicates when separator element change is required.
Indicates fluid level in the sump. Proper level is at the
center of the sight glass. Check level when vacuum
system is shut down. DO NOT OVERFILL.
Used to indicate fluid flow in the return line. When the
Vacuum System is running at full load, fluid flow should
be visible. There may be little or no flow when the vac-
uum unit is running unloaded, but a sluggish flow at full
load indicates a need to clean the return line strainer
or orifice.
Cuts off the reverse flow of gas/fluid mixture through
the Vacuum System inlet at shutdown.
Regulates flow of fluid to and around the cooler.
Designed to maintain a minimum operating tempera-
ture of 180ºF (82ºC); used for fast warm-up on start-
up.
Shuts the vacuum system down when the vacuum unit
discharge temperature exceeds 235ºF (113ºC).
Relieves the sump pressure if the pressure is too high
15 psig (103kPa).
Designed to shut down the vacuum system when the
discharge pressure becomes too high. This switch is
set for shutdown at approximately 12 psig (83kPa).
