DESCRIPTION OF
OPERATION
Drain Valve (not shown):
The drain valve is located at
the base of the air tank and
is used to drain condensation
at the end of each use.
Motor Thermal Overload
Protector (not shown)
:
The electric motor has an
automatic thermal overload
protector. If the motor over-
heats for any reason, the
thermal overload protector
will shut off the motor. The
motor must be allowed to
cool before restarting.
ON/AUTO - OFF Switch (A):
Turn this switch ON to pro-
vide automatic power to the
pressure switch and OFF to
remove power at the end of
each use.
Air Intake Filter (not
shown):
This filter is
designed to clean air coming
into the pump. This filter
must always be clean and
ventilation openings free
from obstructions. See
"Maintenance".
Air Compressor Pump
(not shown):
Compresses
air into the air tank.
Check Valve (not shown):
When the air compressor is
operating, the check valve is
“open”, allowing com-
pressed air to enter the air
tank. When the air compres-
sor reaches “cut-out” pres-
sure, the check valve
“closes”, allowing air pres-
sure to remain inside the air
tank.
Pressure Release Valve
(not shown):
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 continuous leaking after
unit reaches cut-out pres-
sure.
Pressure Switch (B):
The
pressure switch automatical-
ly starts the motor when the
air tank pressure drops
below the factory set “cut-
in” pressure. It stops the
motor when the air tank
pressure reaches the factory
set “cut-out” pressure.
