Do not place the AR-1215 or AR-2306 near heat sources such as radiators, heat registers, stoves, or other appliances that produce heat. 4. Route the power cord and other cables so that they are not likely to be walked on, tripped 1 A R - 1 2 1 5 A C L I N E V O LTA G E R E G U L AT O R over, or stressed. Pay particular attention to condition of cords and cables at plugs, and the point where they exit from the AR-1215 or AR2306. To prevent risk of fire or injury, damaged cords and cables should be replaced immediately. 5. Clean the AR-1215 or AR-2306 with a damp cloth only. Do not use solvents or abrasive cleaners. Never pour any liquid on or into the unit. 6. When left unused for a long period of time, the power cord of the AR-1215 or AR-2306 should be unplugged from the outlet. 7. The AR-1215 or AR-2306 should be serviced by qualified service personnel when: ±5V ±5V ±4V ±10V ±10V ±10V AR-1215 AR-1215J AR-1215J AR-2306 AR-2306 AR-2306 120 120 100 220 230 240 97 to 141 97 to 141 80 to 122 174 to 264 181 to 276 190 to 288 NOTE: The three models in the AR-Series differ in their nominal AC output voltages. Model AR-1215 produces 120 VAC. Model AR-1215J produces either 100 or 120 VAC. Model AR-2306 produces either 220, 230, or 240 VAC. Where differences exist between models, information applicable to the AR-2306 is shown in the text of this manual in brackets [ ]. a. The power supply cord or the plug has been frayed, kinked, or cut. b. Objects have fallen or liquid has spilled into the unit. c. The AR-1215 or AR-2306 has been exposed to rain or other moisture. d. The AR-1215 or AR-2306 does not appear to operate normally or exhibits a marked change in performance. e. The AR-1215 or AR-2306 has been dropped, or the enclosure damaged. FIRST: SELECT THE CORRECT VOLTAGE! 8. The AR-1215 or AR-2306 requires that a safety ground be present for proper operation. Any attempt to operate the AR-1215 or AR-2306 without a safety ground is considered improper operation and could invalidate the warranty. 9. There are no user serviceable parts in the AR1215 or AR-2306. Refer servicing to qualified service personnel only. Before using your Voltage Regulator, be sure that if there is an output voltage switch on the rear panel (just above the cord, on Models AR-1215J and AR-2306 only), it is correctly set for the AC voltage required by your equipment. Each item of equipment that you intend to power with the Voltage Regulator should have its required voltage indicated on it, usually on the rear near the cord. If in doubt, consult your dealer. Furman Voltage Regulators are intended to protect sensitive electronic equipment from problems caused by AC line voltage irregularities--brownouts or overvoltages that can cause audio tonal changes, digital equipment malfunction (such as loss of MIDI programs or other data), or, in extreme cases, permanent damage. They accept input voltages over a wide AC voltage range (see table on page 2) and convert them to a steady, stable output at the desired standard voltage, plus or minus five [ten] volts. Voltages approximately ±10% beyond that range may be converted to usable levels, depending on the requirements of the equipment. See graphs on the back page. The AR-1215 has eight [AR-2306 has ten IEC-320] 2 NOMINAL OUTPUT VOLTAGES VS.

All are functionally interchangeable. The outlets are regulated, spike-suppressed, and filtered against RFI with a 3-pole filter, making the unit a full-function power conditioner. The AR-1215 has no controls except an on-off switch. (The AR-1215J and AR-2306 also have an output voltage selector switch.) Note: The AR-1215 and AR-2306 are for use with AC voltage only. DC voltages should never be applied to them. Also, they do not change or regulate line frequency. The output frequency will always be the same as the incoming frequency. you should plan your total load so that it does not exceed 12 amps, or 1400 watts. Please note that this refers to the aggregate power requirement of all equipment plugged into the Voltage Regulator, not to each individual item. The AR-2306 can handle loads totalling up to 6 amperes as long as the input voltage is equal to or above the selected output voltage. For voltages below that level, its capacity must be derated at approximately 23 milliamperes per volt. (Again, please see graphs on back page.) As a practical matter, therefore, to cope successfully with worst-case brownout conditions, you should plan your total load so that it does not exceed 5 amps, or 1100 watts. Please note that this refers to the aggregate power requirement of all equipment plugged into the Voltage Regulator, not to each individual item. MAXIMUM AND MINIMUM LOAD The AR-1215 and AR-1215J can handle loads totalling up to 15 amperes as long as the input voltage is equal to or above 124 volts (or 104 volts if using AR-1215J set to 100 volt output). For voltages below that level, its capacity must be derated at approximately 113 milliamperes per volt. (See graphs on back page.) As a practical matter, therefore, to cope successfully with worst-case brownout conditions, NOTE: While there is no minimum load requirement for the AR1215 or AR-2306, you may experience an audible mechanical hum coming directly from the unit when the POWER switch is on with nothing plugged in. This effect will disappear as soon as you plug in any equipment 15A 120V 50-60HZ A.C.

DEFINITIONS Because noise occurs at higher frequencies than the 50 or 60 Hz AC line, it can be effectively reduced through use of low-pass filtering. VOLTAGE REGULATION: The AC line voltage is a number indicating the nominal electrical potential that has been adopted in a region for powering electrical equipment of all kinds. In most of North America it is 117 volts AC; in Japan, 100 volts; and in many other countries 220, 230, or 240 volts. The actual voltage can fall below or rise above this nominal level due to brownouts, power cutbacks, use of substandard wiring, and other causes. These deviations can cause poor performance or a malfunction. A regulator is a device which, through use of a transformer, corrects the voltage deviation by stepping it up or down so that it is as close as possible to the nominal level. SPIKE: A pulse of energy on the power line. Spikes can have voltages as high as 6000 volts. Though they are usually of very short duration, the energy they contain can be considerable, enough to damage sensitive solid-state components in audio and computer equipment. Spikes can also foul switch contacts and degrade wiring insulation. They are an unavoidable component of electric power. They are caused unpredictably by electric motors switching on or off (on the premises or outside), utility company maintenance operations, nearby lightning strikes, and other factors. Spikes (also called surges or transients) are absorbed by special components called MOV's in the AR-series to provide safe voltage levels to protect your equipment. RFI/EMI INTERFERENCE: Noise from RFI (Radio Frequency Interference) or EMI (Electro Magnetic Interference) involves lower voltages and less energy than is found in spikes, but it is continuous rather than transient in nature. It is not likely to cause physical damage, but it can certainly be annoying, producing static in audio circuits, "snow" on video screens, or garbled data in computers. Noise can be introduced into AC lines by nearby radio transmitters, certain kinds of lighting, electric motors, and others. EXTREME VOLTAGE PROTECTION The AR-Series includes special circuitry to sense over- and under-voltages and positively shut down the output before possible damage is done. See the Specifications on the back page for the exact voltages at which shutdown occurs. When the input voltage exceeds the limit, the power will cut off. It will come back on automatically when the overvoltage is removed as long as the voltage has not exceeded 300V [all models]. The red LED labelled EXTREME VOLTAGE SHUTDOWN indicates the shutdown condition. The output is also shut down for extremely low input voltages. To provide protection against a catastrophic error in AC mains wiring, dangerously high voltages (those over approximately 300V) will cause an internal fuse to blow, but equipment plugged into the Voltage Regulator will not be damaged. FUSES AND CIRCUIT BREAKERS There is one fuse and one circuit breaker in the AR-Series. In the event that the unit appears to be completely dead (neither the Power switch nor any LED's light up), unplug the power cord and the load and check the breaker. If the circuit breaker is tripped, a white button will pop up. Push it back in to reset it. The purposes of these circuit protection devices are: 1. A fast-blow 15 amp [6 amp] circuit breaker is accessible at the rear panel without removing the unit from the rack. This breaker will trip if the unit's 15 amp [6 amp] capacity is exceeded at any time. 2. A fast-blow 1/4 amp fuse is located inside the unit. This fuse will blow if the unit has been connected to a voltage that is above the range 4 A R - 1 2 1 5 A C L I N E V O LTA G E R E G U L AT O R of the Extreme Voltage Shutdown circuitry (approximately 200 VAC for AR-1215 and AR1215J; approximately 400 VAC for AR-2306). To replace it, the unit must be completely disconnected from all power and removed from its ra ...
