General Information
The Vectaire EVO220 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
air throughout the dwelling. The extract and intake air streams are separated
to avoid contamination.
The system will operate continuously to create a stable, comfortable, healthy
environment avoiding the use of excessive energy and saving heat already gen-
erated.
The heat recovery unit will generally be installed in the loft of a house or the void
above the ceiling in an apartment (but may be installed in a cupboard) and will
be connected by hidden ductwork to vents sited in the ceilings of the rooms
which require ventilation. Each unit is commissioned individually allowing its per-
formance to be 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 pol-
lutant 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.
