Key: D A = Discharge Air Sound Power
R A = Return Air Sound Power
C B = Case Breakout Sound Power
S @ 3m = Sound Pressure at 3m
(1) dB(A) is the overall sound level, measured on the A scale.
(2) All sound data measured at nominal conditions.
(3) Refer to Sound Measurement Method.
The Sound Pressure data quoted is only valid where the unit is installed on a solid floor (Front and Rear return air only) or false floor (Base return air only) and against a rear wall. If the
equipment is placed adjacent to any other vertical reflective walls, values may vary to those stated, typically increasing by 3dB for each side added. Values stated do not include for room
reverberation conditions.
