AT THE FOLLOWING STANDARD CONDITIONS:
1 standard supply [voltage  10%]; ambient conditions 24C bs; 50% R.H.(17C bu); condensation temperature: 45C
2 Measured at 1 m height and 2 m front distance, in free field, with working fans and compressor.
3 Measured at 1 m height and 2 m front distance, in free field, with working fans only.
The cooling capacities are meant after deduction of the heat taken from the fans. Therefore the heat must be added to the ambient load. EER refers
to the ambient unit only. The air flow of the units refers to the standard configuration with filter of the G3 class. The standard diameters of the pipes
only apply for lengths - between the air conditioner and the condensing unit - up to 30 equivalent m.
