1.1 Presentation of the manual
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+DX unit.
The non-observance of what is described in this handbook and an inadequate installation of the ERV+DX unit may cause the cancellation of the
guarantee that the Manufacturer/Distributor 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.
1.2 general characteristics
• 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. total heat exchange with temperature efficiency up to 77% and enthalpy efficiency up to 63%, also at high level
during summer season
• G4 efficiency class filters with synthetic cleanable media, both on fresh air and return air intake
• 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
• Low consumption, high efficiency & low noise direct driven fans with 3-speed EC motors
• Supply section complete with DX coil (R410A) fitted with solenoid control valve, freon filter, contact temperature sensors on liquid and gas
line, NTC sensors upstream and downstream airflow
• Purifying system Bioxigen
®
plied air
• Built-in electric box equipped with PCB to control internal fan speed and to interconnect outdoor/indoor units
• Duct connection by circular plastic collars
