3.2 Scope
BEFORE INSTALLING THE APPLIANCE READ THIS
MANUAL CAREFULLY
Residential ventilation appliances convey outdoor air
through the cross-flow heat exchanger and distribute it to
the different rooms by means of a duct distribution system.
Moist and stale air is suctioned and then, again passing
through the cross-flow heat exchanger, is exhausted to the
outside of the appliance by residential ventilation.
3.3 Machine identification
There is an identification label on each appliance bearing
the data of the manufacturer and the machine type (See
Figure “1”).
Fig.1.
4. End of use
