2.1 INTRODUCTION
A heat recovery unit is an essential component of residential controlled mechanical ventilation systems. These
systems represent the most efficient solution from an energy point of view to guarantee adequate ventilation of
the internal environments.
The functioning of a heat recovery unit, with a crossed flow exchange pack, is based on the use of a dedicated
heat exchanger which allows recovery of the thermal energy of the extracted air which, otherwise, would be
dispersed outside.
In this way, energy consumption for space heating or cooling is significantly reduced, while ensuring a high level
of indoor air quality.
The exhaust air of the internal environments is expelled from the building, while the fresh and clean air from the
outside is filtered and introduced inside the building. This process ensures adequate ventilation of the internal
environments, while reducing heat dispersion.
This manual contains a detailed description of the technical specifications of the HI-TECH PUR 4.0 recovery units,
the instructions for its operation, installation and assembly, as well as the technical data.
It is advisable to carefully follow all the instructions provided in this manual to ensure:
• the reduction or elimination of any unforeseen faults;
• an improvement in the performance of the components, with consequent energy savings;
• an increase in the durability of the constituent elements and of the entire unit;
• a reduction in maintenance costs.
