Notes (1)
Cooling capacity, unit power input in cooling and EER are based on the following conditions: SST 7°C;
ambient 35°C, unit at full load operation.
Notes (2)
The values are according to ISO 3744 and are referred to: SST 7°C, ambient 35°C, full load operation.
Notes (3)
Refrigerant and oil charge is for the unit only; doesn't include external suction and liquid line. Units are
shipped without refrigerant and oil charge; holding charge nitrogen 1 bar
