General Information
The Vectaire WHHR125DC- Aera heat recovery system provides
whole house mechanical ventilation to living areas, bedrooms, kitchen
and bathrooms. It extracts stale, contaminated air from kitchens,
utility rooms and bathrooms, and uses the heat recovered from this
air to warm fresh, incoming air to create a flow of fresh, filtered air
throughout the dwelling. The extract and intake air streams are
separated to avoid contamination.
The majority of the heat is reclaimed from extracted air and used, via
the heat exchange process, to warm incoming fresh air. The system
will operate continuously to create a stable, comfortable, healthy
environment avoiding the use of excessive energy and saving heat
already generated.
The heat recovery unit must be installed vertically, and will generally be
sited in the loft of a house or the void above the ceiling in an
apartment, or in a cupboard. It will be connected by hidden ductwork
to vents sited in the ceilings of the rooms which are to be ventilated.
Each unit is commissioned individually so that the amount of air moved is tailored to suit the performance
required. There will be a facility to boost the extraction rate when desired (e.g when cooking or bathing, or
when pollutant levels rise). This may be done automatically or manually.
The system is designed to run continuously and should NOT be switched off except for maintenance or filter
replacement. It is important to follow the advice in this user manual and correctly install and maintain the
system to ensure a healthy and comfortable indoor environment.
