• The fan may be operated only in a
permanent indoor installation and with
its power supply line concealed.
• The maximum temperature of the
medium handled by the air exhaust fan
and the maximum ambient temperature
are +40°C.
• The air exhaust fan is an IPX4 and
protection class II device. The fan can
be installed in indoor moisture Zone II,
in accordance with PN-IEC 60364-
7-701, provided that the following
requirements from the air exhaust fan
manufacturer are complied with:
1 - the correct wall-mounting position
is maintained with a proper seal of the
power supply line in the grommet (see
Section “Installation”).
2 - the air exhaust duct is secured by
a cover from direct exposure to water
per IPX4 and direct access to live and/
or rotating parts, including the fan rotor
in motion; or the air exhaust duct is at
least 800 mm long and installed with
special tools which will be required to
access the air exhaust fan for servicing.
• The fan must be operated according to
its intended use and within the perfor-
mance limits speced on the nameplate.
• Connect the air exhaust fan to the
building mains (electrical system) with
the following power cable: NYM-O
2x1.5 mm² (H07V-K 2x1.5 mm²) or
NYM-O 3x1.5 mm² (H07V-K 3x1.5 mm²),
maximum outer diameter 9.5 mm,
depending on the optional accessories
provided (does not apply to the models
with the supply cable attached).
• Do not use the fan to handle the air
with the following content:
- viscous contaminants prone to deposi-
tion in the fan,
- corrosive contaminants which may
degrade the fan,
- flammable contaminants, including
gas, vapours, mists or particulates
which may form explosive mixtures
with air.
• The devices equipped with ball
bearings are designed for a minimum
operating life of 30,000 hours in S1 duty
cycle at the maximum power output and
the maximum ambient temperature.
• The control system must prevent
extremely frequent power cycling.
Transport and storage
• Keep the fans in their original packag-
ing in a dry, sheltered room.
• The transport and storage ambient
temperature limits are -20 °C to +40 °C.
• Protect against impact and shocks.
Transport the fan in its original
packaging
• If the storage time exceeds 1 year,
the motor bearings of the fan must be
tested by turning the fan rotor by hand
before installation. The fan rotor must
run smoothly.
• Dispose of the fan at the end of its
operating life strictly in accordance with
environmental protection and waste
management laws.
• Should it occur, damage caused by
improper transport, handling, storage
or commissioning will be demonstrated
and is not on warranty.
