A 0
B 1013
C 1.000
D 1.000
Legend:
A = Altitude above sea level (m)
B = Barometric pressure (mbar)
C = Correction factor of the cooling capacity
D = Correction factor of the absorbed power
The maximum operating altitude is 2000 m above sea level.
Contact the factory if the unit is to be installed at altitudes 1000 m above sea level.

AAT(2)
B(1)
Legend:
AAT = Ambient air temperature (°C) (2)
A = Ethylene glycol (%) (1)
B = Propylene glycol (%) (1)
(1) Minimum percentage of glycol to prevent freezing of the water circuit at the indicated ambient air temperature
(2) Ambient air temperature that exceeds the operating limits of the unit.
Protection of the water circuit is necessary in the winter season, even when the unit is not operating.
