• 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 in
Zone 2, 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 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
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 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.
ACCESSORIES
Available optional accessories:
Terminal block (standard version,
no part index suffix). Connect the air
exhaust fan with the terminal block as
shown in the electrical wiring diagram,
see Fig. 2. The air exhaust fan is
started and stopped by a separate
on/o switch installed in the power
supply line of the building (and not
included with the product). Stop
delay timer air (part index suffix ‘T’).
Connect the exhaust fan with the
stop delay timer (a stop delay switch)
as shown in the electrical wiring
diagram, see Fig. 3. The stop
delay time can be set with a
potentiometer knob on the electronic
