Harman Kardon PA 4000 Owners Manual - Page 4

Safety Information Important Safety Information Verify Line Voltage Before Use Your new Harman Kardon PA 4000 amplifier has been factory-configured for use with 120volt AC line current. Connecting the amplifier to a line voltage other than that for which it is intended can create a safety and fire hazard, and may damage the amplifier. If you have any questions about the voltage requirements for your specific model, or about the line voltage in your area, contact your selling dealer before plugging the unit into a wall outlet. Verify AC Circuit Capacity Before Use High-power output of your amplifier may require heavy current draw under full load conditions. To ensure proper performance and avoid potential safety hazards, we recommend that it be connected to a circuit with 20-amp capacity. Connecting multiple amplifiers to the same circuit, or connecting the amplifier to a circuit used by other heavy-power devices, such as high-wattage lights, may cause circuit breakers to trip. It is always a good idea to avoid using any audio equipment on the same AC circuit as equipment with motors, such as air conditioners or refrigerators. This will lessen the possibility of power variation and electrical start-up noise affecting your sound system. Do Not Use Extension Cords To avoid safety hazards, use only the power cord supplied with your unit. If a replacement cord is used, make certain that it is of a similar gauge. We do not recommend using extension cords with this product. As with all electrical devices, do not run power cords under rugs or carpets or place heavy objects on power cords. Damaged power cords should be replaced immediately with cords meeting factory specifications. Handle the AC Power Cord Gently When disconnecting the power cord from an AC outlet, always pull the plug; never pull the cord. If you do not intend to use the amplifier for a considerable length of time, disconnect the plug from the AC outlet. Do Not Open the Cabinet There are no user-serviceable components inside this product. Opening the cabinet may present a shock hazard, and any modification to the product will void your guarantee. If water enters the unit, or any metal object such as a paper clip, wire or staple accidentally falls inside the cabinet, disconnect the unit from the AC power source immediately and consult an authorized warranty station. Installation Location s To ensure proper operation and to avoid the potential for safety hazards, place the unit on a firm and level surface. When placing the unit on a shelf, be certain that the shelf and any mounting hardware can support the amplifier's weight. s Make certain that the proper space is provided both above and below the unit for ventilation. If the amplifier will be installed in a cabinet or other enclosed area, make certain that there is sufficient air movement within the cabinet. Consult with your dealer or installer for more information. s Do not place the unit directly on a carpeted surface. s Avoid installation in extremely hot or cold locations, in an area that is exposed to direct sunlight or near heating equipment. s Avoid moist or humid locations. s Do not obstruct the ventilation slots on the top of the unit or place objects directly over them. Remember, power amplifiers generate heat, and the heatsink fins and ventilation slots that form part of the cabinet are specially designed to remove this heat. Placing other electronic equipment near these heatdissipation systems may possibly affect the long-term reliability of both your amplifier and the objects placed above it. Cleaning When the unit gets dirty, wipe it with a clean, soft and dry cloth. If necessary, first wipe the surface with a soft cloth slightly dampened with mild soapy water, followed by a fresh cloth with clean water. Wipe immediately with a dry cloth. Never use benzene, thinner, alcohol or any other volatile cleaning agent. Do not use abrasive cleaners, as they may damage the finish of metal parts. Avoid spraying insecticide near the unit. Moving the Unit Before moving the unit, be certain to disconnect any interconnection cords with other components, and make certain that you disconnect the unit from the AC outlet. Unpacking and Installation The carton and shipping materials used in protecting your new amplifier were specially designed to cushion it from the shocks and vibration of shipping. We suggest that you save the carton and packing materials for use in shipping if you move or if the unit ever needs repair. To minimize the size of the carton in storage, you may wish to flatten it. Carefully remove any staples used to close carton seams; carefully slit the tape on the bottom and collapse the carton. Other cardboard inserts may be stored in the same manner. Packing materials that cannot be collapsed should be saved along with the carton in a plastic bag. When positioning the amplifier in its final location, make certain that it has adequate ventilation on all sides, as well as on the top and bottom. Do not place CDs, record jackets, owner's manuals or other paper on top of or beneath the unit or in between multiple amplifiers in a stack. This will block the air flow, causing degraded performance and a possible fire hazard. If the unit is to be enclosed in a cabinet or rack, make certain that there is adequate air circulation, with means provided for hot air to exit and for cool air to be brought in. 4 SAFETY INFORMATION
