This manual describes the rules for the transportation, the installation, the use and the maintenance of the heat recovery. The user will find every-
thing that is normally useful to know for a correct and safe installation of the ERV+ X unit.
The non-observance of what is described in this handbook and an inadequate installation of the ERV+ X unit may cause the cancellation of the
guarantee that the Manufacturer/ istributor Company grants on the same one. The Manufacturer/distributor Company, moreover, does not
answer to possible direct and/or indirect damages due to wrong installation carried out by inexpert and/or non-authorised staff. At the moment
of the purchase, check that the machine is integral and complete. Claims will have to be produced within 8 days from the reception of the goods.
• Galvanized steel self-supporting panels, internally and externally insulated
• Counterflow air-to-air heat recovery device, made of plane sheets of special paper with special sealing to keep airflows separate and only
permeable to water vapor. with temperature efficiency up to 76% and enthalpy efficiency up to 67%, also at high
level during summer season
• ISO 16890 Coarse 50% + ePM2.5 95% (F9 EN779) efficiency class filters on fresh air, Coarse 50% (G3 EN779) filer on return air intake. All
filters are made with synthetic cleanable media.
• Removable side panel to access filters and heat recovery in the event of scheduled maintenance
• Motorised heat recovery by-pass device automatically controlled by unit control to use fresh air free-cooling when convenient
• , high efficiency & low noise direct driven fans with
• (R410A) fitted with solenoid control valve, freon filter, contact temperature sensors on liquid and gas
line, NTC sensors upstream and downstream airflow
• , switched on at fans running, able to do an efficient antibacterial treatment, ensuring a perfect healthi-
ness of supplied air
• Built-in electric box equipped with PCB to control internal fan speed and to interconnect outdoor/indoor units
• uct connection by circular plastic collars
