VUT/VUE 160/350/550 V(1)(B) EC
PURPOSE
The unit is designed to ensure continuous mechanical air exchange in houses, offices, hotels, cafés, 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 supply 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).
Relative humidity of transported air must not exceed +20 °C at an ambient humidity of 80 %.
THE UNIT SHOULD NOT BE OPERATED BY CHILDREN OR PERSONS WITH REDUCED
PHYSICAL, MENTAL, OR SENSORY CAPACITIES, OR THOSE WITHOUT
THE APPROPRIATE TRAINING.
THE UNIT MUST BE INSTALLED AND CONNECTED ONLY BY PROPERLY QUALIFIED
PERSONNEL AFTER THE APPROPRIATE BRIEFING.
THE CHOICE OF UNIT INSTALLATION LOCATION MUST PREVENT UNAUTHORIZED
ACCESS BY UNATTENDED CHILDREN.

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
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.
