The unit is designed for indoor application with the ambient temperature ranging from +1 °C up to +40 °C and relative humidity up to 80 %.
In order to prevent condensation on the internal walls of the units, it is necessary that the surface temperature of the casing is 2-3 °C higher 
than the dew point temperature of the transported air.
The unit is rated as a Class I electrical appliance.
Hazardous parts access and water ingress protection rating:
•  IP22 for the unit connected to the air ducts
•  IP44 for the unit motors
The unit design is constantly being improved, thus some models may be slightly different from those described in this manual.
