SECURITY AND APPLICATION
• The fans are certified according to ATEX 94/9/EEC
and comply with ISO 14694, category BV-2, BV-3
and ISO 1940 quality factor G 6.3.
• Standards: SS-EN 50014:1997, SS-EN 50019, EN
13463-1 and parts of prEN 14986:2006.
• There are two versions of fan motors that have dif-
ferent rate data. See table 1.
• The fans are adapted to transport gas in explosion
environment.
• The fans must not be connected to a flue gas duct.
• The fans are powered by short-circuit 3-phase
motor.
• The fans are adapted for continuously operation S1.
• The fans must not be installed outside.
• The fans can only be used in zone 1 and are not zone
separating,i.e. transported air and ambient air of the
fan must be in the same zone.
• The environmental temperature of the fan and the
temperature of the media that is transported must
be in the interval of –20°C to +40°C.
• The fans must not be used to transport media (com-
pact or running) that can establish sediments or cor-
rosiveness on the impeller, motor or casing.
• Rust particles are not to occur in the airflow.
• The fan can be installed vertically or horizontally.
• At speed regulation the fans can be run by a trans-
former with a voltage of 25% up to 100% of the rated
voltage. See table 2. If the transformer is installed in
the same zone as the fan, it must have the similar
ATEX classification.
• The fans cannot be electronic regulated or regulated
with a frequency converter.
• The fans must be connected electrically via a re-
setting proof vertical discharge with a contact clea-
rance of at least 3 mm/pole.

ENGLISH

INSTALLATION
• Installation and maintenance according to the appli-
cable national rules. For members of CENELEC in
European countries should the national standards
based on EN 60079-14 and EN 60079-17 be take
into consideration.
• For the electrical connection see table 1 and wiring
diagram in fig. 1 to 3.
• Check possible transport damages of the fan. A
damage fan must not be installed in any circum-
stances.
• Check the distance between the impeller and inlet
cone and the distance between the impeller and the
casing.These distances must be a minimum of 4 mm.
• Installation and starting must be made by an autho-
rised electrician according to directions and require-
ments. Electrical installation must be made accor-
ding to EN 60079-14 that complies with the safety
requirements of high tension current.
• Installation according to appended wiring diagram.
• The fan must be grounded.
• An external motor protection must be installed (is
an accessorie, see fig. 4). If the motor protection is
installed in the same zone as the fan, it must have
the similar ATEX classification.
• Before starting the fans must be connected to duct
or equipped with a safety grill to preclude contact
of moving parts (EN 294).
• The fans are only intended for firm installation.
• The fans should be installed in a safe way,not risking
to fall off, to be expose for or cause vibrations.
• If installation cause vibrations, the fans must be con-
nected to duct via a flange.
• Precautions must be taken to prevent material to be
sucked or fall into the fan, when vertically mounted.
Minimum IP 20 <_ Ø12,5 mm at the inlet side and
IP 10 <_ Ø 50 mm at the outlet side.
• The fan must be installed according to the air direc-
tion label.
• The fan should be installed in a way that makes ser-
vice and maintenance easy and safe.

The stated current on the marking sign must not be exceeded. If the fans are speed regulated by a transformer the current can be
exceeded for some of the fans, but only if the rated power is not exceeded.

OPERATION
Before starting, make sure that:
• the fan is installed and electrically connected in the
correct way with ground and a motor-protection.
• no foreign objects are in the fan and no noise appe-
ars when starting the fan.
• the rotation direction are according to the label. If
the fan rotates in wrong direction, change place of 2
phases and rotation direction will be right.
• the current does not exceed what is stated on the
label.
MAINTENANCE
• Before service, maintenance or repair begins, the fan
must be tension free and the impeller must have
stopped.
• Consider the weight of the fan when removing or
opening larger fans to avoid jamming and contu-
sions.
• The fan must be cleaned when needed, at least once
per year to maintain the capacity and to avoid unba-
lance, which may cause unnecessary damages on the
bearings.
• When cleaning the fan, also check if the fan has any
damages in a way that can cause a change of the dis-
tance between impeller and inlet cone or the dis-
tance of impeller and the casing. If so, the fan needs
to be exchange.
• The fan bearings are maintenance-free and have a
lifetime of about 30.000-40.000 operation hours or
5 years. Contact the fan supplier to renew the bea-
rings.
• When cleaning the fan, high-pressure cleaning or
strong dissolvent must not be used. Cleaning should
be done without dislodging or damaging the impel-
ler.
• Make sure that there is no noise from the fan.
• The screws tightening capacity of the service lid:
M6=9,8 Nm; M10=45 Nm.
• Components in ATEX-approved products must not
be repaired or change.
HOW TO HANDLE
• The fans must be stored in a dry place.
• If the fans have been stored for a long time, the ball-
bearings of the fan must be checked before starting
so it operates properly.
• Avoid storage longer than one year.
• The fan must be transported in its packing until
installation. This prevents transport damages, scrat-
ches and the fan from getting dirty.
• Use an adequate cable lift when handling the fans to
avoid damages of fans and people.
• The fans must not be lifted in the motor cable,
impeller or inlet cone.
• Attention, look out for sharp edges and corners.

FAULT DETECTION
If the fan has stopped or do not start.
1. Make sure that there is tension to the fan.
2. Cut the tension and verify that the impeller is not
blocked.
3. Check the motor protector. If it is disconnected the
cause of overheating must be taken care of, not to be
repeated.
4. If nothing of this works, contact your fan supplier.
5. At possible complaint, the fan must be cleaned, the
motor cable undamaged and a detailed nonconfor-
mity report enclosed.
CONDITIONS ACCORDING TO CERTIFICATE SP06ATEX3127X
1. The thermal PTC-circuit of the motor must be con-
nected to a thermo-contact relay, (Certified accor-
ding to directive 94/9/EC) which cut the motor-
supply when motor tempe-rature is to high.
2. Connected fan to duct system must be installed with
requirements of rate IP 20 on inlet side and IP 10 on
outlet side. The parts that are included in these IP-
protections must be constructed in an appropriate
way, in strength and material.
3. To avoid explosion hazard, the connection cable of
the fan must be rigid connected, mechanically pro-
tected and protected from other environmental
influence. To protect from explosion the free cable
end must be connected according to installation
requirement.
4. The stated current on the marking sign must not be
exceeded. If the fans are speed regulated by a trans-
former the current can be exceeded for some of the
fans according to the table in the certificate.But only
if the rated power is not exceeded.
