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
Additional Regulators and Controls | Fig. 3 |
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.
