WARNING
WARNING — THE INSTALLATION MUST BE CARRIED OUT BY A QUALIFIED ELECTRICIAN.
• Risk of property damage, injury or death. Installation, service, and maintenance
must be performed by a qualified service technician
• 110 or 220 Volts may cause serious injury from electric shock. Disconnect
electrical power before starting installation or servicing. Leave power
disconnected until installation/service is completed
• The unit must be ceiling mounted. Please mount the unit with the access
door facing down
• Sharp edges may cause serious injury from cuts. Use care when
handling duct work
• Inhalation of toxic gases or fumes can be harmful. The fresh air intake
must be mounted in a location removed from sources of dangerous toxic
gases. All ducting must be separate from other household exhaust systems
• Insu cient combustion air may cause toxic conditions. The unit must not exhaust air from an enclosed
room with combustion appliances
• Excess negative or positive pressure may cause health problems or structural damage. The airflow must be balanced
a er installation
• Dropping may cause personal injury or equipment damage. Handle with care and follow installation instructions
CAUTION
PLEASE READ INSTRUCTION BEFORE COMMENCING INSTALLATION AND RETAIN FOR FUTURE REFERENCES.
The installation must conform to all applicable codes. The fresh air duct from outside and to the house and the stale air duct from the unit to
the outside must be fully insulated to prevent condensation from forming on the duct work
STRUCTURE AND OPERATING LOGIC
The unit has the following operating logic (Figure 1):
Warm stale extract air from the room flows through the air ducts to the unit, is
purified in the extract filter and is supplied to the heat recovery core and
exhausted outside by exhaust fan. Clean cold air from outside is moved by
supply fans to the unit where it is purified through the supply filter. Then clean
air flows through the heat recovery core and is supplied to the room by supply
fan.
Thermal energy of warm extract air is transferred to clean intake fresh air and
warms it up. The extract and intake air flows are fully separated during heat
recovery which excludes any transfer of odors and pathogens to supply air.
Heat recovery minimizes thermal energy losses, energy demand and
heating costs.
Both sensible thermal energy and latent moisture energy contained in the
extract air are transferred in the unit heat recovery core to the cold intake air
flow from outside to warm it up before supplying to the room.
ERVs: The graphene modified polymer membranes core of the unit operates
as a moisture balancer in case of too low outdoor humidity or as an air dryer
in case of high outdoor air humidity. Due to high hygroscopic features of the
heat and energy recovery core material the unit does not need condensate
drainage. Application of the heat exchanger provides decreasing thermal
energy losses and heating costs saving during cold season.
HRVs: The Aluminum heat recovery core of the unit operates as a temperature
balancer in case of big temperature di erence between indoor and outdoor.
When the air streams flow crossly through the core, it may produce conden-
sate, so there will be a condensate drainage on the unit.
