MAIN TECHNICAL PARAMETERS

The unit is designed for indoor application with the ambient temperature ranging from +1 °C (+34 °F) up to +40 °C (+104 °F) and 

relative humidity up to 80%. 

The transported air temperature must be from -20 °C (-4 °F) up to +50° C (+122° F).

The unit is classi

fi

 ed as a class I electric appliance. 

Ingress Protection (IP) rating from solid objects and liquids: 

 

IP 44 for the unit motors;

 

IP 22 for the assembled unit integrated into air ductworks.

The unit design is regularly improved, so some models may slightly di

ff

 er from those ones described in this manual.
