DESIGN AND OPERATING PRINCIPLE
The unit has the following operating logic: warm stale extract air from the room flows into the unit, where it is filtered by the extract filter,
then air flows through the heat exchanger and is exhausted outside by the extract fan. Cold fresh air from the outside flows into the unit,
where it is cleaned by the supply filter.
Then the air flows through the heat exchanger and is directed to the room with the supply fan. Heat energy of warm extract air is
transferred to clean intake fresh air from the outside and warms it up. The air flows are fully separated while flowing through the heat
exchanger. Heat recovery minimizes heat losses, which reduces the cost of space heating in the cold season.

The service side of the unit is equipped with a detachable plate for filter and heat exchanger cleaning and replacement operations.
The control unit is positioned inside the unit casing. The power cable and grounding cables are connected to the control unit via the
electric lead-ins placed at the side of the unit. The difference between the supply and extract air flow temperature leads to condensate
generation. Condensate is collected in the drain pan and is removed outside through the drain pipes.
