General Information
The Vectaire EVO350 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 bath-
rooms, 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 generated.
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 cup-
board) and will be connected by hidden ductwork to vents sited in the
ceilings of the rooms which require ventilation. Each unit is commis-
sioned individually allowing its performance 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 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.
