1 Introduction and safety
The unit is a balanced ventilation system with heat
recovery for energy-efficient ventilation in homes.
Balanced ventilation means that stale air from the
kitchen, the bathroom, the toilet(s) and other wet rooms
is extracted, while the same amount of fresh air is
supplied to the living room, bedrooms and other dry
rooms. Gaps under the doors ensure a good airflow in
the dwelling.
Ensure that the gaps under or near
doors are never obstructed. For
example by furniture, draught excluders
or deep-pile carpet.
A balanced ventilation system consists of:
■
The unit (A);
■
Duct system for fresh and exhaust air (B);
■
Duct system for supply and extract air (C);
■
Supply valves in the living areas, bedrooms and any
other dry rooms (D);
■
Return valves in the kitchen, bathroom, toilet and any
other wet rooms (E).
