Notes
- 1 Chilled water from 20 to 15°C, ambient air temperature 35°C.
- 2 Chilled water from 20 to 15°C, ambient air temperature 46°C.
- 3 Sound pressure level measured in free field conditions at 1 m from the unit. According to ISO 3744.
- N.B. (1) The nominal inlet/outlet water temperature at notes (1) and (2) is 3 degrees lower than nominal inlet/outlet water temperature on cooling door to take into account the presence of LPS Leak Prevention System.
