Certain air compressors can be converted
from
120V to 240V operation. When converting an
air compressor
to 240V
operation,
the
attached
three-prong
120V cord assembly
must be replaced with a three-pronged
240V
cord assembly that can be purchased through
a Sears Service Center.
Some models have a dual voltage motor, 120 and 240
volt. They are wired for 120 volt but can be converted
to 240 volt operation.
Instructions
for connecting
the
motor for operation
at 240 volt can be found printed on
the label attached to the side of the motor.

Certain
air compressor
models
can be operated
on a 15 amp circuit
if:
1.
Voltage
supply to circuit is normal.
2.
Circuit
is not used to supply any other electrical
needs (lights, appliances,
etc.)
3.
Extension
cords comply with specifications
in
this manual.
4.
Circuit
is equipped
with a 15 amp circuit
breaker
or 15 amp
time delay fuse.
Extension
Cords
To avoid voltage drop and power Ioss to the motor, and to
prevent overheating, use extra air hose instead of an
extension cord.
If an extension cord must be used:
use only a 3-wire extension
cord that has a 3
blade grounding
plug and a 3-slot receptacle tnat
will accept
the plug on the extension
cord
make sure the extension
cord is in good condition.
the extension
cord should be no longer than 50
feet.
•
the minimum
wire size is 12 gauge (AWG). (Wire
size increases
as gauge number decreases.
10
AWG and 8 AWG may also be used. DO NOT USE
14 AWG or 16 AWG.)
can gather and freeze. Apply pressure before under-
ground lines are covered to make sure all pipe joints
are free of leaks.
Connect the piping to the 3/8" NPT air outlet opening
at the end of the air tank.
Additional
Regulators
and Controls
Since the air tank pressure is usually greater than that
which is needed, a separate regulator
is employed
to
control the air pressure ahead of any individual air
driven device.
Separate air transformers
which combine
the function
of air regulation,
moisture and dirt removal should be
used where applicable.
Break-in
Procedure
Serious damage may result if the following
break-in
instructions are not closely fol-
lowed.
This procedure is required only once, before the air com-
pressor is put into service.
1. Set the pressure switch "AUTO/O"
lever in the
"O" position
for "Off".
2. Plug the power cord into the correct branch circuit
receptacle.
3
Do net attach hose to outlet. Leave the outlet open
to the atmosphere.
f
Turn the regulator clockwise,
opening it fully, to
prevent air pressure build-up
in the tank.
5
Move the "AUTO/O" lever to "AUTO".
The com-
pressor wil! start,
6
RUN THE COMPRESSOR
FOR 30 MINUTES.
Make sure the regulator is open and there is no tank
pressure
build-up.
7. After 30 minutes, close the regulator by turning it
counterclockwise.
The air tank will fill to cut-out
pressure and then the motor will stop.
Piping
Plastic
or PVC pipe is not designed
for use with
compressed
air, Regardless
of its indicated
pressure
rating,
plastic
pipe can burst from air
pressure.
Use only metal pipe for air distribution
lines.
If a pipe line is necessary,
use pipe that is the same
size as the air tank outlet. Piping that is too small will
restrict the flow of air. If piping is over 100 feet long,
use the next larger size. Bury underground
lines below
the frost line and avoid pockets
where condensation
