"EVO90DC" - WHOLE HOUSE HEAT RECOVERY UNITS
INSTALLATION AND OpERATINg INSTRUCTIONS
Safety Notice
It is important to read this Instruction Manual carefully before installing or using the product. Following
these instructions will ensure that your ventilation system is installed, commissioned and used properly and
continues to operate effectively. Vectaire will not be held responsible and will not accept liability for any
damage caused to persons or property through failure to follow the guidance provided in this manual. It
should always be available with the product for easy reference.
general Information
The Vectaire EVO90DC heat recovery system provides whole house
mechanical ventilation to living areas, bedrooms, kitchen and bath-
rooms. 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 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 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 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.
