DELIVERY SET
PURPOSE
The unit is designed to ensure continuous mechanical air exchange in houses, offices, hotels, cafes, conference halls, and other utility
and public spaces as well as to recover the heat energy contained in the air extracted from the premises to warm up the filtered stream
of intake air.
The unit is not intended for organizing ventilation in swimming pools, saunas, greenhouses, summer gardens, and other spaces with
high humidity.
Due to the ability to save heating energy by means of energy recovery, the unit is an important element of energy-efficient premises.
The unit is a component part and is not designed for stand-alone operation. It is rated for continuous operation.
Transported air must not contain any flammable or explosive mixtures, evaporation of chemicals, sticky substances, fibrous materials,
coarse dust, soot and oil particles or environments favourable for the formation of hazardous substances (toxic substances, dust,
pathogenic germs).

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:
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.
