General characteristics
1
Hydraulic unit: Sound pressure level at (x) m from the appliance,
1.5m off the ground, open fi 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 fi 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 R32 as per NF EN 378.1 standard.
4
Filling with refrigerant R32 is done at the factory.
5
Taking into account a possible additional fi ll of refrigerant R32
(see "Additional fi lling", page 28).
6
The announced thermal and acoustic performances are measured
with 7,5m length refrigerant lines.
