System specifications Size Depth: 445 mm (17.5 in.) Width: 200 mm (7.9 in.) Height: 492 mm (19.4 in.) Weight Maximum configuration (as shipped): 17.3 kg (38 lb) Environment Air temperature: - System on: 10° to 35°C (50° to 95°F) at altitude 0-2134 m (7000 ft) - System off: −40° to 70°C (−40° to 158°F) Humidity: - System on: 8% to 80% - System off: 8% to 80% Heat output3 Approximate heat output in British thermal units (Btu) per hour: - Maximum configuration (as shipped): 306 Btu/hour (90 watts) - Maximum configuration (theoretical)2: 1564 Btu/hour (460 watts) Electrical input3 Sine-wave input (50/60 Hz) is required Input voltage: - Low range: - Minimum: 90 V ac - Maximum: 137 V ac - High range: - Minimum: 180 V ac - Maximum: 265 V ac - Input kilovolt-amperes (kVA) (approximately): - Maximum (configuration as shipped): 0.75 kVA Acoustical noise-emission values4 Average sound-pressure levels: - At operator position: - 37 dBA idle - 42 dBA operating - At bystander position-1 meter (3.3 ft): - 34 dBA idle - 36 dBA operating Declared (upper limit) sound power levels: - 5.0 bels idle - 5.2 bels operating 2 Under typical maximum configurations, the heat output will be substantially below the theoretical maximum.
