The CAD HE 325/450/575 heat recovery unit is designed for indoor installation.
We recommend a min. temperature of >10ºC in the room where the unit is installed
to guarantee a good efficiency of the unit.
In areas where temperatures can be below -10º C in the winter time, it is
necessary to install a pre-heating device.
