Efficiency is rated based on ANSI/AHRI standard 1060. 2. Operating current and power consumption vary depending on the condition. 3. Operating sound is measured at 59 in. below the center of the unit in an anechoic chamber. Operating sound level generally becomes greater than this value depending on the operating conditions, reflected sound and peripheral noise. 4. The sound level at the air discharge port is about 8 dB higher than the above operating sound. 5. The specifications, designs and information here are subject to change without notice.
