    Connection ports designation: INTAKE – outdoor air intake duct EXHAUST – used air exhaust duct EXTRACT – duct removing used air from rooms SUPPLY – duct supplying air to rooms 1.9. 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.
  • Page 11 SECURING ANGLE BAR - After hanging the air handling unit on a wall bracket, the angle bar protecting it against accidental sliding off the wall bracket must be attached. ● STANDING INSTALLATION - For standing installation, feet appropriate to the model of appliance are required. Do not use other feet than those provided by the manufacturer (feet sold separately).
  • Page 12 Minimum lengths of ventilation ducts To ensure the best efficiency of the air handling unit and to reduce aerodynamic losses due to turbulence, it is recommended to install a straight section of air duct at the entry and exit of the unit. The minimum recommended lengths of such straight sections: - 25 cm of an air conduit at the inlet side;...

    ● Recommended duct thickness depending on ambient temperature: Ventilation duct ambient temperature Air duct type: from -20°C to 0°C from 1°C to 14°C from +15°C to 20°C Insulation thickness for a given temperature range Supply 20 mm + (200 mm)* 50 mm 20 mm Exhaust:...
  • Page 14 Fan maintenance (once a year) Even with regular maintenance of the filters and recuperator, dust deposits may accumulate in the fans, which reduces the efficiency of the air handling unit and the amount of air supplied to the rooms. Use a soft cloth or brush to clean the fans. In order to avoid possible damage to the rotor, do not use water, chemically aggressive solvents, sharp objects etc.

  • Page 15: Preheater

    Maintenance of the air ducting (every 5 years) Even if all the aforementioned maintenance activities of the air handling unit are performed properly, dust deposits may build up inside the air ducts, which reduces the air handling unit's efficiency. Air ducts are maintained by periodic cleaning or changing them.
