1 Introduction and safety
The unit is a balanced ventilation system with heat
recovery in order to create energy-efficient ventilation
in houses. Balanced ventilation means that pollutants
from the kitchen, the bathroom, the toilet(s) and
possibly the storage room are extracted, while the
same amount of fresh air is blown into the living room
and bedrooms. Gaps under or near the doors ensure
a good through-flow in the dwelling.
Ensure that the gaps under or near the door 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 the supply of outdoor air (B);
Duct system for the exhaust of indoor air (C);
Supply valves in the living room and bedrooms (D);
Exhaust valves in the kitchen, bathroom, the toilet
and (if present) the storage room (E).
