Table 6: Extended Piping Wall Mounted Indoor Unit Sound Pressure Data.
• Measurements are taken 3.3 feet (1 m) away from the front of the unit.
• Sound pressure levels are measured in dB(A) with a tolerance of ±1.
• Reference acoustic pressure 0dB=20
μ Pa.
• Data is valid at nominal operation conditions. Operating conditions are assumed to be standard.
• Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745, and may
be different according to the test condition or equipment.
• Sound level will vary depending on a range of factors including the construction (acoustic ab-
sorption coefficient) of a particular room in which the unit was installed.
