DESIGN AND OPERATING PRINCIPLE

The unit has the following operating principle:
Warm stale extract air from the room flows to the unit, where it is filtered. 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 supply filter. Then filtered air flows through the rotary heat exchanger and the 
electric heater (for the KOMFORT Roto EC S2(E)200 units) where it is warmed up 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. Heat recovery minimizes heat losses and space 

heating expenses in cold seasons and cooling expanses in warm seasons.

The unit is equipped with an additional extract spigot for connecting a kitchen hood. The kitchen hood must be equipped with an air damper to 

shut off the exhaust duct when the kitchen hood is not in use.

The unit is a framework construction made of rigidly fixed panels. The 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 and the grounding bus located in the 
control unit.  The wiring diagram is shown on the control unit cover.
