• The air exhaust 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 2, 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 installation in a ceiling
or wall 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 air exhaust fan must be operated
according to its intended use and within
the performance limits specified 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 7.5 mm,
depending on the optional accessories
provided.
• Do not use the fan to handle the air
with the following content:
- viscous contaminants prone to
deposition in the air exhaust fan,
- corrosive contaminants which may
degrade the air exhaust fan,
- flammable contaminants, including
gas, vapours, mists or particulates
which may form explosive mixtures
with air.
• The d
evices 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 air exhaust fans in their
original packaging 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 air exhaust fan in its
original packaging.
• If the storage time exceeds 1 year,
the motor bearings of the air
exhaust fan must be tested by
turning the fan rotor by hand before
installation. The fan rotor must run
smoothly.
• Dispose of the air exhaust 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.
