dB(A) is the overall sound level, measured on the A scale.
2
All sound data measured at nominal conditions: Water in/out 12/7°C at 35°C ambient.

Based on standard unit, for units fitted with optional extras, please contact Airedale.
The Sound Pressure data quoted is only valid in free field conditions, where the unit is installed on a reflective base. If the equipment is
placed adjacent to a reflective wall, values may vary to those stated, typically increasing by 3dB for each side added.
