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.
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.
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).
The temperature in the room where the indoor unit of the ventilator is installed must be in the range from +1 ˚C to +40 ˚C
with relative humidity up to 65 % (no condensation build-up). If the conditions for using the ventilator are beyond the specified
limits, turn off the ventilator and provide fresh air supply through windows. The inlet air temperature must be in the range
from -20 ˚C to +40 ˚C.
The unit is rated as a class II electric appliance and must not be grounded. Valuated ingress Protection (IP) rating from solid
