ADDITIONAL REGULATORS AND CONTROLS
Since the air tank pressure is usually greater than that which is needed, an
air pressure regulator should be employed to control the air pressure ahead
of any individual driven device. An air control unit which combines the
function of air regulation, moisture and dirt removal should be used.
OPERATION CONTROLS
CHECK VALVE (A) FIG.7.
When the air compressor is operating, the check
valve is “open”, allowing compressed air to enter the air tank. When the air
compressor reaches its “Cut-Out” pressure, the check valve “closes”,
allowing air pressure to remain inside the air tank.
TANK PRESSURE GAUGE (A) FIG. 8.
The tank pressure gauge indicates
the reserve air pressure in the tank.
ON/AUTO-OFF SWITCH (B) FIG.8.
Turn this switch ON to provide power to
the automatic pressure switch and OFF to remove power at the end of each
use.
PRESSURE SWITCH (C) FIG.8.
The pressure switch automatically starts the
motor when the tank pressure drops below the factory set “Cut-In” pressure.
It also stops the motor when the air tank pressure reaches the factory set
“Cut-Out” pressure.
ASME SAFETY VALVE (A) FIG. 9.
If the pressure switch does not shut off
the air compressor at its cutout pressure setting, the safety valve will protect
against high pressure by “popping out” at its factory set pressure (slightly
higher than the pressure switch cut-out setting).
WARNING!
: If the safety valve does not work properly, over pressurization
may occur, causing air tank rupture or an explosion. Daily pull the ring on the
safety valve to make sure that the safety valve operates freely. If the valve is
stuck or does not operate smoothly, it must be replaced with the same ASME
type of valve.
BALL VALVE OUTLET PRESSURE LEVER (B) FIG. 9.
This lever controls
the amount of pressurized air in the air delivery piping system.
DRAIN VALVE (A) FIG.10.
The drain valve is located at the base of the air
tank and is used to drain condensation at the end of each use. Turn drain
valve counterclockwise to open (no pressure build-up) or clockwise to close
it (permits pressure build-up).
