Installation, Use and Maintenance Manual - HKFD1EC/C Series
SECTION 1 - GENERAL CHARACTERISTICS
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 HKFD1EC/C unit.
The non-observance of what is described in this handbook and an inadequate installation of the HKFD1EC/C 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 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
•
Low consumption
, high efficiency & low noise direct driven fans with
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
•
Option Purifying system Bioxigen
®
, 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
• Duct connection by circular plastic collars
