Dewalt DXCMLA3706056 Instruction Manual - Page 13

English • 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. 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. Air Distribution System 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. 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. 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 ins­ truc­tions for the air tools and accessories being used. • 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. 13
