Wiring and Grounding Instructions
One of the most important aspects of operating compressors is proper wiring and grounding. This ensures safety and reduces the risk of electrical shock. The compressors are designed to operate on a standard household 15 amp circuit. It is crucial to ground the product by providing an escape wire for the electric current in case of a short circuit. The compressor comes with a cord that has a grounding prong, which should fit into common outlet types. If a plug doesn't fit, it is recommended to have it replaced by a qualified electrician.
Overload Protection and Voltage Conversion
To prevent motor damage from overload conditions, the compressor is equipped with a built-in overload switch. This switch will automatically shut off the motor if an overload occurs. It can be reset by pressing the red button. However, if the overload switch trips repeatedly, it is important to identify and fix the root cause of the problem.
Some Campbell house felt cast-iron air compressors have dual voltage motors that allow operation at either 120 volts or 240 volts. By referring to the connection diagram on the motor nameplate and consulting with a qualified electrician, the compressor can be connected for 240 volts if necessary. This requires changing the 120 volt plug furnished with the compressor to a 240 volt plug. It is essential to connect the product to an outlet that has the same configuration as the plug.
Piping and Pressure Requirements
Proper piping is crucial for optimal compressor performance. Any tube, pipe, or hose used must have a pressure rating higher than 150 psi. For pipe sizes up to 50-foot lengths, it is recommended to use a minimum of 1/2 inch diameter. If the length exceeds 50 feet, using a 3/4 inch or larger diameter pipe is preferable.
Lubrication and Maintenance
Lubrication is essential for the smooth operation and longevity of compressors. These compressors require oil for proper functioning. It is important to check that the oil drain extension and cap have been installed. If not, remove the oil drain plug from the base of the pump and install the oil drain extension for easy oil draining. Before adding oil to the pump, remember to cap the extension to avoid oil leaks. Thread sealant tape should be applied to the threads on each end of the oil drain extension.
The compressor is shipped with a plug in the oil fill opening, which should be removed before filling the pump with oil. After filling the oil to the proper level, install the breather found in the parts pack into the opening. Industrial grade air compressor oil such as SAE 30 or full synthetic motor oils like Mobil 1 10w30 should be used. Regular automotive oils are not recommended as they can cause valve deposits and reduce pump life.
Startup and Break-In Period
Before starting the compressor for the first time, it is recommended to run it continuously for 30 minutes. This allows proper seating of the piston rings. The compressor pump must be filled with oil before startup. After the break-in period, drain and replace the oil.
Operation and Pressure Control
The basic operation of an electric air compressor is controlled by a pressure switch. This device automatically turns the motor off when the tank pressure reaches a preset level. When the air is used and the tank pressure drops to a preset low level, the pressure switch turns the motor back on. There are two gauges on the unit - the tank pressure gauge located behind the pressure switch and the outlet pressure gauge on the left of the pressure switch.
To control the outlet pressure, turn the regulator knob to the right to increase pressure and to the left to decrease it. The compressor will build up to the maximum preset pressure and shut off. If the compressor does not automatically shut off at the preset pressure, the safety valve will activate to prevent excessive pressure buildup in the tank.
Safety Measures and Shutdown Procedure
It is essential to follow safety measures while operating the air compressor. Always turn the pressure switch lever or knob to the "off" position before performing any maintenance or adjustments. Unplug the power cord and slowly turn the regulator knob clockwise to release all air pressure before proceeding further. Attach the air hose to the outlet port of the regulator and connect the air tool to the other end of the hose. Plug in the power cord and turn the pressure switch lever or knob to the "auto" position. Once the desired outlet pressure is achieved, turn the pressure switch lever or knob to the "off" position.
If the compressor is not going to be used for an extended period, it is advisable to bleed air from the line and use the drain valve to remove water from the tank. Proper maintenance schedule should be followed as mentioned in the product manual.
Long-Term Storage and Maintenance Schedule
When the compressor is not in use for a long period, it is important to properly store it. This involves draining the tank, removing any air from the line, and following the maintenance schedule. Regular check-ups and maintenance will ensure the compressor's longevity and optimal performance.
Conclusion
Operating an air compressor requires adherence to specific wiring and grounding instructions, proper voltage conversion, and adequate piping. Lubrication is necessary for optimal performance, and a proper break-in period is recommended. Understanding the operation and pressure control mechanisms, following safety measures, and performing regular maintenance will enhance the compressor's lifespan and efficiency.
