-Genera Information
The Vectaire EVO350 heat recovery system provides who e house
mechanica venti ation to iving areas, bedrooms, kitchen and bathrooms .
It extracts sta e, contaminated air from kitchens, uti ity rooms and bath-
rooms, and uses the heat recovered from this air to warm fresh,
incoming air to create a f ow of fresh air throughout the dwe ing. The
extract and intake air streams are separated to avoid contamination.
The system wi operate continuous y to create a stab e, comfortab e,
hea thy environment avoiding the use of excessive energy and saving
heat a ready generated.
The heat recovery unit wi genera y be insta ed in the oft of a house or
the void above the cei ing in an apartment (but may be insta ed in a cup-
board) and wi be connected by hidden ductwork to vents sited in the
cei ings of the rooms which require venti ation. Each unit is commis-
sioned individua y a owing its performance to be tai ored to suit the
performance required. There wi be a faci ity to boost the extraction
rate when desired (e.g when cooking or bathing or po utant eve s rise).
This may be done automatica y or manua y.
The system is designed to run continuous y and shou d NOT be switched off except for maintenance or fi ter
rep acement. It is important to fo ow the advice in this user manua and correct y insta and maintain the
