the principles of static, heat recovery ventilation (HrV)
In a Heat Recovery system, air is renewed mechanically
by being pumped into the living accommodation whilst bein
gextracted from the bathroom and kitchen areas.
Fresh air is fed into the dwelling via supply ducts and diffused
by grilles located in the living room and bedrooms.
The ‘used’ air extracted via the grilles in high humidity rooms
is fed through a heat exchanger before being discharged into
the outside air. The heat exchanger can recover up to 90% of
the calories from the outgoing air to preheat the incoming air.
Microwatt or standard fan motor unit:
responsible for the supply of fresh air and the extraction of
stale air whilst limiting energy consumption, particularly
with the microwatt version.
Highly efficient heat exchanger:
used to recover calorific energy from the air extracted.
Flat ductwork:
facilitates the integration of the system
into the dwelling and reduces pressure losses.
Thermally-insulated network outside of heated area.
Distribution casing:
Distributes balanced volumes into
each room. Facilitates the integration of the system into
a suspended ceiling void.
supply grilles:
Used to supply air to the bedrooms and
living
room, these grilles can be fitted into walls or the cei-
ling and the air-jet can be adjusted.
self-balancing extraction grille:
Used to extract used air
and discharge it outside.
Controls:
used to set the ventilator speed and displays
filter blocked warnings.
Fresh air inlet and used air outlet.

TECHNICAL DETAILS
average electrical consumption – Microwatt motors
average electrical consumption – standard motors
assembly precautions
• 230V–50Hz single-phase power supply
• Connections to the electrical mains should be
fitted by a qualified professional in accordance
with the rules laid down in NF C 15-100 or in
compliance with applicable regulations in the
country of installation. A contact-breaking
device with a separation of at least 3 mm should
be used on each pole.
• the electrical connections must use flexible
cabling which must have a cross section at least
equal to that of H05VV-F or H05RR-F.
• If the supply cable is damaged it must be
replaced, by a professional, with a cable of the
same reference, respecting the rules of NF C
15-100.
Precautions prior to starting up
• When starting up, all ductwork, including
exhausts and fresh air inlets, must be connected
correctly.
• Never place your hands in front of in inlet or
outlet orifice.
installation precautions
• If installing in an open hearth fire emplacement,
refer to the applicable regulations in the country
of installation.
