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 on which the air compressor is operated. If the compressor is

connected to a circuit protected by fuses, use only dual element time delay fuses.

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 can gather and freeze. Apply pressure before underground

lines are covered to make sure all pipe joints are free of leaks.

A flexible coupling needs to be installed between the air discharge valve outlet and

main air distribution line to allow for vibration.

GROUNDING INSTRUCTIONS

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.

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. 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 Fig. 3.

DO NOT USE AN ADAPTER.

Inspect the plug and cord before each use. Do not

use if there are signs of damage.

Improper grounding can result in

electrical 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 connect 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.

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.
