The unit has the following operating logic:
Warm stale extract air from the room flows to the unit, where it is filtered by the extract filter. Then the air is moved through the rotary
heat exchanger and is exhausted outside with the exhaust fan. Clean cold air from outside is moved to the intake filter. Then filtered air flows
through the rotary heat exchanger and the water heater where it is warmed up to the pre-set temperature value and is moved to the room
with the supply fan.
Heat energy of warm extract air is transferred to clean intake fresh air from outside and warms it up in the rotary heat exchanger. Heat
recovery minimizes thermal energy losses and space heating expenses in cold seasons.
The unit is a framework construction that includes a frame made of rigidly fixed sandwich panels. The three-layer sandwich panels are made
of aluminium and galvanized sheets, internally filled with a heat- and sound-insulated layer of mineral wool.
The air handling unit is equipped with quick-detachable service panels for scheduled repair and maintenance operations.
Route power and ground cables through the screwed cable glands to connect those to the terminal block located in the control unit. The
wiring diagram is shown on the inner side of the control unit cover.
