ACOUSTIC DATA

Indoor Units

Figure 5: High Efciency Standard Wall Mount Indoor Unit Sound Level

Measurement.

• Measurements are taken 3.3 ft away from the front of the unit.

• Sound pressure levels are measured in dB(A) with a tolerance of

±3.

• Data is valid at nominal operation conditions. Operating conditions

are assumed to be standard.

• Reference acoustic pressure 0dB=20μPa

• 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 absorption coefficient) of a particular room in

which the unit was installed.
