Tank life is dependent upon several factors, some of which include operating conditions, ambient conditions, proper installations, field modifications, and the level of maintenance. The exact effect of these factors on air receiver life is difficult to predict. If proper maintenance procedures are not followed, internal corrosion to the inner wall of the air receiver tank can cause the air tank to unexpectedly rupture allowing pressurized air to suddenly and forcefully escape, posing risk of injury to consumers. Your compressor air tank must be removed from service by the end of the year shown on your tank warning label. The following conditions could lead to a weakening of the air tank, and result in a violent air tank explosion: WHAT CAN HAPPEN HOW TO PREVENT IT • Failure to properly drain • Drain air tank daily or after each condensed water from air use. If air tank develops a leak, tank, causing rust and thinning replace it immediately with of the steel air tank. a new air tank or replace the entire compressor. • Modifications or attempted repairs to the air tank. Attachments & Accessories: • Exceeding the pressure rating of air tools, spray guns, air operated accessories, tires and other inflatables can cause them to explode or fly apart, and could result in serious injury. Tires: • Over inflation of tires could result in serious injury and property damage. • Never drill into, weld or make any modifications to the air tank or its attachments. Never attempt to repair a damaged or leaking air tank. Replace with a new air tank. 5 • Follow the equipment manufacturers recommendation and never exceed the maximum allowable pressure rating of attachments. Never use compressor to inflate small low pressure objects such as children’s toys, footballs, basketballs, etc. • Use a tire pressure gauge to check the tires pressure before each use and while inflating tires; see the tire sidewall for the correct tire pressure. NOTE: Air tanks, compressors and similar equipment used to inflate tires can fill small tires very rapidly. Adjust pressure regulator on air supply to no more than the rating of the tire pressure. Add air in small increments and frequently use the tire gauge to prevent over inflation.

Place the 3/8” lag screws through the air compressor feet, vibration pads and into the anchors. 7. Torque 3/8” lag screws to 7-10 ft.-lbs (9.5-13.5 Nm). HUMID AREAS In frequently humid areas, moisture may form in the pump and produce sludge in the oil, causing running parts to wear out prematurely. Excessive moisture is especially likely to occur if the unit is located in an unheated area that is subject to large temperature changes. Two signs of excessive humidity are external condensation on the pump when it cools down and a “milky” appearance in compressor oil. You may be able to prevent moisture from forming in the pump by increasing ventilation or operating for longer intervals. NOISE CONSIDERATIONS Consult local officials for information regarding acceptable noise levels in your area. To reduce excessive noise, use vibration mounts or silencers, relocate the unit or construct total enclosures or baffle walls. Contact a DeWALT service center or call 1-888-895-4549 for assistance. Wiring Instructions Anchoring of the Air Compressor WARNING: Improper electrical installation of this product may void its warranty and your fire insurance. Have circuit wiring performed by qualified personnel such as a licensed electrician who is familiar with the current national electrical code and any prevailing local electrical codes. WARNING: Risk of bursting. Excessive vibration can weaken the air tank and cause an explosion. The compressor must be properly mounted. The air compressor MUST be bolted to a level, solid concrete surface. Use 3/8” lag screws, vibration pads and concrete anchors. If help is needed anchoring the air compressor consult a licensed contractor. 1. Place the air compressor on a level, solid concrete surface. Make sure the concrete is in good condition with no cracks or damage. WARNING: Risk of electrical shock. Improper electrical grounding can result in electrical shock. The wiring should be done by a qualified electrician. A qualified electrician needs to knows the following before wiring: 1. The amperage rating of the electrical box should be adequate. 12 If any of the above conditions cannot be met, or if operation of the compressor repeatedly causes interruption of the power, it may be necessary to operate it from a 20 amp circuit. It is not necessary to change the cord set. Main power disconnect switch Install a main power disconnect switch in the line from the panel to the compressor. The main power disconnect switch must be located near the compressor, for ease of use and safety. When turned OFF, the main power disconnect switch shuts off all power to the compressor. When it is turned ON, the compressor will start and stop automatically, controlled by the pressure switch. WARNING: Risk of electrical shock. Electrical wiring must be located away from hot surfaces such as manifold assembly, compressor outlet tubes, heads, or cylinders. Air Distribution System Grounding Instructions WARNING: Risk of bursting. 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. This product should be connected to a metallic, permanent wiring system, of and equipment-grounding terminal or lead on the product. Voltage and Circuit Protection INSTALLING AND DISCONNECTING HOSES WARNING: Risk of unsafe operation. Firmly grasp hose in hand when installing or disconnecting to prevent hose whip. Ensure regulated pressure gauge reads 0 psi. Refer to the Voltage and Minimum Branch Circuit Requirements under Specifications. CAUTION: Certain air compressors can be operated on a 15 amp circuit if the following conditions are met. • Voltage supply to circuit must comply with the National Electrical Code. • Circuit is not used to supply any other electrical needs. • Extension cords comply with specifications. • Circuit is equipped with a 15 amp circuit breaker or 15 amp time delay fuse. NOTE: If compressor is connected to a circuit protected by fuses, use only time delay fuses. Time delay fuses should be marked “D” in Canada and “T” in the U.S. The next figure represents a typical air distribution system. The following are tips to remember when setting up the air compressor’s air distribution system. NOTE: Compressed air from oil lube air compressors will contain water condensation and oil mist. Several drains, traps and filters will be needed to supply air without water (including aerosols) or oil to spray equipment, air tools and accessories requiring filtered air. Always read the instructions for the air tools and accessories being used. 13 English Refer to the Specifications, in the parts manual, for this information. 2. The supply line should have the same electrical characteristics (voltage, cycle, phase) as the motor. Refer to the motor nameplate, on side of motor, for this information. NOTE: The wiring used must be rated for the motor nameplate voltage, plus or minus 10%. Refer to local codes for recommended wire sizes, correct wire size, and maximum wire run; undersize wire causes high amp draw and overheating to the motor. English • • • • • • • 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’ (30.5 m) 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 is recommended to be installed between the globe valve/air discharge outlet and main air distribution line to allow for vibration. A separate regulator is recommended to control the air pressure. Air pressure from the tank is usually too high for individual air driven tools. DO NOT install lubricators between the tank and any spray equipment, air tool or accessory requiring oil-free filtered air. Drain all traps, filters and dirt legs daily.
