Sound levels are referred to unit at nominal condition when installed in false ceiling and connected to ducts. External static pressure 50 Pa.
Cooling: Ambient temperature 35°C D.B./ 24°C W.B., Extracted air temperature 27°C D.B./ 19°C W.B.
Average sound pressure level, according to UNIEN ISO 3744, is measured at 1m distance from the unit surface, when installed in false ceiling and con-
nected to ducts.
Power measurements are according to UNI EN ISO 9614-2, with unit connected to ducts and installed in the vicinity of a reflecting surface, allowing 2 dB
(A) tolerance.
Noise values referred to:
• standard operation with air flow rate from 320mc/h to 125mc/h
• SILET mode with air flow rate from 210mc/h to 125mc/h
• SUPER SILET mode with air flow rate 125mc/h
SILENT and SUPER SILENT modes (setting from remote control) operate a reduction of compressor and fan speed, reducing their noise emission
Please note that noise levels may differ significantly if the unit is installed in different conditions (ex: with surrounding obstacles, walls or similar).
