User instrucons
General
The Fumex FB fan is a radial fan for the evacuaon of
gases, smoke and low weight parcles. The fan series
conforms to the protecon and safety regulaons in
the EU's Machinery Direcve. The fans boast high
levels of quality and operaonal reliability. ALL fans
undergo inspecon and test operaon before leaving
the factory. However, risks can arise with any fan if:
- it is not installed, used or maintained by trained
personnel.
- it is not used in the intended manner.
Please note that electronic equipment is always
suscepble to stac electricity, high humidity,
high temperatures and line failures. The
equipment is supplied with high voltage. Use the
isolang switch when carrying out service work
on the fan.
The fans are not intended for use in the
evacuaon of explosive gases.
Fan installaon
Installaon may only be performed by authorised
personnel with regard to these installaon
instrucons and applicable regulaons. Make sure
that all safety-related fan components sasfy their
funcon. The stability of the fan must always be
ensured during operaon. In order to achieve
opmum funcon, it is important for the fan's duct
connecons to be correctly executed. Incorrect
installaon can cause considerable deterioraon in
the fan's performance with regard to pressure drop
and sound levels.
In order to achieve opmum performance, we
recommend that the inlet connecon is a straight
duct that is 5 mes the diameter of the duct. If an
outlet duct is used, the same applies to this. If the
system requires a 90° bend in the outlet, it should
deviate in the impeller's direcon of rotaon (see
below).
There is always a risk of clothes or loose items
being sucked into a free-blowing fan. This can
cause personal injury or damage to property.
The fan is supplied with the outlet poinng as
illustrated on page 1. If an alternave outlet air
direcon is required, the fan housing can be set in 8
possible posions. If the direcon of outlet is changed,
thread locking must be applied to the screws. Take
great care to ensure that the impeller is not damaged
when reinstalling the fan housing.
In the event of outdoor installaon, a drainage hole
must be drilled at what becomes the lowest point in
the installed fan, according to the selected outlet
direcon.
In the case of professional installaon, too, fans
can produce harmful noise levels. It should also
be noted that specified noise data (see separate
product sheet) can be altered by the surroundings
or resonance in the operang locaon.
The fans are designed for installaon in systems
and therefore have no guard on the inlet. This
means that the fan must not be started unl it is
connected to a duct. The guard installed on the
outlet can be removed if you want to connect an
outlet duct (see accessories on page 8).
Maintenance
Fumex fans have been designed for connuous use for
an extended me with a high level of reliability. Like all
machines, regular servicing and maintenance are
required to achieve opmum funcon.
Fumex recommends the following maintenance
schedule:
Component Interval 6 months
Motor Check funcon. Replace motor if
necessary.
Impeller Check for any damage and clear
away foreign objects if necessary.
Replace impeller in the event of
damage.
Fan housing Check that connecons are secure
and clear away foreign objects.
Check the drainage hole and clear
if necessary.

Outdoor wall installaon
Outdoor roof installaon
A flexible installaon that opmises
the pressure drop on the inlet side.
Makes it possible to choose outlet
direcon. In the event of
condensaon problems, installaon
as illustrated is recommended. If
noise levels are the priority, it is
recommended to have the outlet
poinng straight up, with drainage
in the fan housing (for drainage see
page 3).
Note! The fan bracket must be
made on site.
An installaon that is used when
low noise levels are priorised.
The disadvantage of this
arrangement is that the fan is
located high up if the extract air
duct is high.
Note! The fan housing needs to be
drained (for drainage see page 3).
A low-level, sideways outlet
direcon is suitable in the event of
condensaon problems.
Note! The base must be made on
site due to possible snow.
Upwards outlet direcon, suitable
in the event of noise problems.
Note! Drainage is required (for
drainage see page 3).
A high-level, sideways outlet
direcon is suitable when conden-
saon is not a problem.
Note! Drainage is required (for
drainage see page 3).

Electrical installaon
The equipment is supplied with high voltage and
must always be fied with a safety switch for
carrying out servicing work in connecon with the fan.
The choice of cable and cable cross-secon must comply
with the naonal requirements that apply to fixed
installaons.
Troubleshoong
Always go through the troubleshoong schedule
before contacng Fumex. This schedule contains
informaon that makes it easy to idenfy faults that
are simple to recfy.
Set external safety switch in the off posion.
The fan can start up without warning following
a power outage
Only qualified personnel may perform servicing
work on the fan.
Symptom Possible fault
The fan has
stopped
Loss of
performance
In order to sasfy applicable standards, the FB fan
must be fied with a contactor and overcurrent protecon.
To choose the correct contactor, see page 6.
If technical regulang apparatus
(e.g. frequency converter) is used, the manufacturer's
recommendaons for avoiding interference must be
observed. E.g. EMC, protecve earth, cable length,
cable shielding, etc..
The one phase motor is equipped with double capacitors.
When the fan is not operang in full running speed, i.e.
during the start-up and shut down process, the motor
produces a mechanical sound, deriving from the switch
between the two capacitors. This is a normal sound and
it is not harmful for the motor.
Three-phase fans are supplied with the motor
connected for 400V (Y-connecon).
D-connection Y-connection
Single phase fans are supplied with the motors
connected for clockwise rotaon. The speed of the
single phase motors CANNOT be regulated.
Fault in the power supply.
Check the power supply.
Short circuit in connecon.
Check for moisture in the
safety switch and motor
connecon.
Locked impeller
Check that there are no
foreign objects in the fan
housing.
Locked impeller
Check that no ice has formed
in the fan housing.
Locked impeller
Check that the bearing in
the motor is working.
Motor winding
Check for resistance between
windings.
Debris
Check that there are no
foreign objects in the fan
housing.
Incorrect direcon of
rotaon
Check the direcon of
rotaon.
Connecons
Check that connecons and
duct roung are correct.
