2.Description of the unit
2.1 Unit identification
2.2 Description
High efficiency heat recovery units Altair HRM guarantee the continuous ventilation of large rooms such as
industrial and service sectors with medium efficiency where the heat of the expelled air is to be recovered, thus
reducing the energy consumption of the building to a minimum and keeping the ambient air healthy at all times.
All units are equipped with AC (forward-bladed) centrifugal fans with 3-4 speeds complying with the ErP 2015
standard, while the heart of the Altair HRM is a counter-current aluminium heat exchanger that guarantees a
recovery efficiency of up to 73%, sufficient to access the highest energy efficiency classes.
The 25 mm polyurethane foam insulation, sandwich between two Aluzinc panels, ensures a high degree of
thermal insulation of the air flows in order to avoid the dispersion of the recovered heat.

This operation must be performed ONLY BY QUALIFIED STAFF
Install the unit through appropriate means (weight from 100 kg to 380 kg) in order to avoid risks
during the load handling procedures. Do not stand under the unit until it is completely attached to the
ceiling. During installation you may need to work at height (over 2m H). Therefore evaluate the risks of
falling, inert suspension or generic injury and take the necessary precautions.
PPE: Personal Protective Equipment
3.2 Condensate drainage installation
The unit is equipped with condensate drainage to evacuate the water during normal operation. Should always be
provided with a drain pipe siphon and minimum slope of 3% in order to avoid stationing of condensate. The siphon
is essential for the proper
functioning of the machine in order to avoid sucking air and allow the natural flow of condensate.
