Table 8: Indoor Unit Acoustic Data
Figure 9: Sound Pressure Levels for LAN090HYV3 Indoor Unit.
• Measurements are taken 3.28 ft away from the front of the unit.
• Sound pressure levels are measured in dB(A) with a tolerance of ±3.
• Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745.
• Sound level will vary depending on a range of factors including the construction (acoustic absorp-
tion coefficient) of a particular room in which the unit was installed.
