    Please read the Operating Manual carefully before assembling it or any other activity related to work with the device! AWENTA shall not be liable for any damage resulting from incorrect operation, non-intended use or unauthorised repairs or modifications of the product.

  • Page 5: Intended Use

    1.2. INTENDED USE The unit is equipped with a cross-flow plate heat exchanger, electric heater (optional) and is designed to save thermal energy by its recuperation, being one of the elements used in energy-saving technology systems. The unit is considered a supplementary device and must not be used as a stand-alone, independent heating source.

  • Page 9: Operation Principle

    1.8. OPERATION PRINCIPLE Fresh air is drawn in with the air intake located outside the building. Then, using ventilation ducts, the air is transported to the air handling unit. After filtering, it flows to the heat exchanger where heat energy exchange from the exhaust stream takes place.
  • Page 10 Draining of condensate The condensate drip tray provided with a pipe to drain the condensate outside the unit. The condensate drain pipe should be connected to the building's drainage system via a trap. The pipes have to be arranged with a slope of approximately 2%. NOTE: Fill the drain system with water, before connecting the unit to the power network! The drain trap must be filled with water during operation at all times.

  • Page 11: Maintenance

    1.11. MAINTENANCE It is absolutely necessary to disconnect the control panel from power supply before performing any maintenance operations. Filter replacement/cleaning Fouled filters increase air flow resistance which reduces the amount of air supplied to the rooms, and increases power consumption by the fans.
