Drain Valve: The
drain valve is located
at the base of the air
tank and is used to
drain condensation at
the end of each use.
Check Valve: When the air
compressor is
operating, the
check valve
is "open",
allowing
compressed
air to enter
the air tank.
When the
air compressor reaches "cut-out"
pressure, the check valve "closes",
allowing air pressure to remain inside
the air tank.
Pressure Release Valve: The
pressure release
valve located on
the side of the
pressure switch,
is designed to
automatically
release
compressed
air from the
compressor head
and the outlet tube when the air
compressor reaches "cut-out" pressure
or is shut Off. The pressure release
valve allows the motor to restart freely.
When the motor stops running, air will
be heard escaping from this valve for a
few seconds. No air should be heard
leaking when the motor is running
or after the unit reaches "cut-out"
pressure.
Motor Overload Protector (not
shown): The motor has an automatic
reset thermal overload protector. If
the motor overheats for any reason,
the overload protector will shut
Off the motor. The motor must
be allowed to cool down before
restarting. The compressor will
automatically restart after the motor
cools.
