Additional Regulators and Controls
Since the air tank pressure is usually greater than that which is
needed, a separate regulator is usually employed to control the
air pressure ahead of any individual air driven device.
Break-in Procedures
Serious damage may result if the following break-
in instructions are not closely followed.
This procedure is required:
1. Before the air compressor is put into service. (Before the
hose is installed.)
2. When the check valve is replaced.
3. When a complete compressor pump is replaced.
a. Set the pressure switch lever to the "OFF" position.
b. Plug the power cord into the correct branch circuit
receptacle.
c. Turn the regulator clockwise opening it fully, to
prevent air pressure build-up in the tank.
d. Move the pressure switch lever to "ON/AUTO". The
compressor will start.
e. Run the compressor for 15 minutes. Make sure the
regulator is open and there is no tank pressure build-
up.
f. After 15 minutes, close the regulator by turning it
counterclockwise. The air receiver will fill to cut-out
pressure and the motor will stop. The compressor is
now ready for use.
IMPROPER GROUNDING CAN RESULT IN ELEC-
TRICAL SHOCK.
Do not modify the plug that has been provided. If it does not fit
the available outlet, the correct outlet should be installed by a
qualified electrician.
If repairing or replacing cord or plug, the grounding wire must
be kept separate from the current-carrying wires. Never con-
nect the grounding wire to a flat blade plug terminal. The
grounding wire has insulation with an outer surface that is
green - with or without yellow stripes.
If these grounding instructions are not completely understood,
or if in doubt as to whether the compressor is properly grounded,
have the installation checked by a qualified electrician.
GROUNDING INSTRUCTION — (Portable Units)
RISK OF ELECTRICAL SHOCK! In the event of a
short circuit, grounding reduces the risk of shock by
providing an escape wire for the electric current.
This air compressor must be properly grounded.
The air compressor is equipped with a cord having a grounding
wire with an appropriate grounding plug. The plug must be
used with an outlet that has been installed and grounded in
accordance with all local codes and ordinances. The outlet
must have the same configuration as the plug. See illustration.
DO NOT USE AN ADAPTER.
Inspect the plug and cord before each use. Do not use if there
are signs of damage.
Voltage and Circuit Protection
Refer to the specification chart for voltage and circuit protection
requirements of your compressor. Use only a fuse or circuit
breaker that is the same rating as the branch circuit the air
compressor is operated on. If the compressor is connected to
a circuit protected by fuses, use only dual element time delay
fuses.
Plastic or PVC pipe is not designed for use with
compressed air. Regardless of its indicated pres-
sure rating, plastic pipe can burst from air pres-
sure. 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 can gather and freeze. Apply pressure
before underground lines are covered to make sure all pipe
joints are free of leaks.
It is recommended that a flexible coupling be installed between
the air discharge valve outlet and main air distribution line to
allow for vibration.
