TECHNICAL DATA
The unit is designed for indoor application with the ambient temperature ranging from +1 °C up to +40 °C and relative humidity up to
60 % without condensation. In cold, damp rooms, there is a possibility of freezing or condensation inside and outside the casing.
In order to prevent condensation on the internal walls of the unit, it is necessary that the surface temperature of the casing is 2-3 °C above
the dew point temperature of the transported air.
The unit should be operated continuously, and in cases where ventilation is not necessary, reduce the air flow of the fans to a
minimum (20%). This will ensure a favorable indoor climate and reduce the amount of condensation inside the unit, which can damage
electronic components. Never use the unit for dehumidification, for example, of new buildings.
The unit is rated as a Class I electrical appliance.
Hazardous parts access and water ingress protection rating:
IP20 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.
