Hydraulic unit: Sound pressure level at (x) m from the appliance, 1.5m o󰀨 the ground,
open eld directionality 2 / Outdoor unit : Sound pressure level at (x) m from the device,
halfway between the ground and top of the outdoor unit, open eld directionality 2.
2
The sound power level is a laboratory measurement of the emitted sound
power. It does not correspond to a measurement of the perceived sound power.
3
Refrigerant R410A as per NF EN 378.1 standard.
