GENERAL THEORY OF OPERATION
1.
The
POWER CORD (1)
sends the electrical supply to the
PRESSURE SWITCH (2)
. When the
PRESSURE SWITCH LEVER (3)
is in the "Auto" position,
power is supplied to the
ELECTRIC MOTOR (4)
which is protected from electrical overloads by the
MANUAL RESET BUTTON (5)
.
2.
The
COMPRESSOR PUMP (6)
is lubricated by oil. The oil level should be checked before each use by removing the
COMPRESSOR PUMP OIL
DIPSTICK (7)
. Fill to proper level with SAE-30W non-detergent oil if needed.
3.
When the unit is operating, the
V-BELT (8)
turns the
COMPRESSOR PUMP FLYWHEEL (9)
which rotates the crankshaft and moves the
PISTONS (10)
.
4
As the
PISTON (10)
moves down, air is drawn in through the
INLET
AIR FILTER (11)
and then through the
INLET REED VALVE (12)
. At the same time,
the
OUTLET REED VALVE (13)
is closed. This allows air to fill the piston chamber.
5.
As the
PISTON (10)
moves up, the
INLET REED VALVE (12)
closes and the
OUTLET REED VALVE (13)
opens allowing the compressed air to flow into
the
PUMP DISCHARGE LINE (14)
.
6a.
STANDARD START/STOP FEATURE:
1.
The compressed air opens the
CHECK VALVE (15)
and moves into the
AIR TANK (16)
. When the pressure in the
AIR TANK (16)
reaches the
maximum pressure setting of the
PRESSURE SWITCH (2)
, the
ELECTRIC MOTOR (4)
stops and the
CHECK VALVE (15)
will close.
2.
The pressurized air remaining in the
PUMP DISCHARGE LINE (14)
exits through the
PRESSURE SWITCH BLEND-OFF LINE (17)
so the
ELECTRIC MOTOR (4)
can restart under a no-load condition.
6b.
OPTIONAL DUAL CONTROL FEATURE:
1.
This feature consists of a
PILOT CONTROL VALVE (18)
which has an
ADJUSTING KNOB (19)
with two positions.
a.
Start/Stop Position:
Turn the
ADJUSTING KNOB (19)
completely
clockwise
to the
closed
position. Air compressor will
operate as described in the Start/Stop Feature as explained above.
b.
Constant Run Position:
Turn the
ADJUSTING KNOB (19)
completely
counterclockwise
to the
open
position. The compressed air
opens
the
CHECK VALVE (15)
and moves into the
AIR TANK (16)
. When the pressure in the
AIR
TANK
(16)
reaches the maximum pressure setting of the
PILOT CONTROL VALVE (18)
, the excess
air
exits
the
PILOT VALVE MUFFLER (20)
and the
CHECK VALVE (15)
will close. Since the relief setting
on
the
PILOT CONTROL VALVE (18)
is lower than the maximum pressure setting on the
PRESSURE
SWITCH
(2)
the
ELECTRIC MOTOR (4)
will continue running. This feature is very useful under low
voltage conditions, when motor starting can trip the circuit breaker (fuse).
7.
The
SAFETY RELIEF VALVE (21)
protects the system from any overpressure conditions.
8.
The
TANK PRESSURE GAUGE (22)
indicates tank pressure. The
AIR PRESSURE REGULATOR (23)
can be adjusted to the desired operating pressure
which is indicated on the
OUTLET PRESSURE GAUGE (24)
. The air exits through the
OUTLET FITTING (25)
.
9.
The
PRESSURE SWITCH LEVER (3)
stops the
ELECTRIC MOTOR (4)
when moved to the “OFF” position.
10.
When the
PRESSURE SWITCH LEVER (3)
is in the "off" position, compressed air should be released from the
AIR TANK (16)
by opening the attached air
tool or by pulling on the
SAFETY RELIEF VALVE (21)
. When the
TANK PRESSURE GAUGE (22)
registers less than 10 PSI, drain the condensation from
the
AIR TANK (16)
by opening the
TANK DRAIN (26)
.
