• 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.

Before starting, make sure that:
• the fan is installed and electrically connected in the
correct way grounded and with 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.

• Before service, maintenance or repair begins, the fan
must be tension free (re-setting proof vertical dis-
charge) and the impeller must have stopped.
• Consider the weight of the fan when removing to
avoid clamping and crushing or deformation that
may damage the fan.
• 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. The fan should be inspected with regular
intervals with regard to noise, abnormal tempera-
tures or vibrations.
• Clean the inside of the fan via the fan inlet and out-
let openings. The impeller may not be loosened from
the shaft. Also clean the grill for the motor cooling
fan and motor cooling fins should be done.
• 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 exchanged.
• The fan bearings are maintenance-free and have a
lifetime of about 10.000-20.000 operation hours.
Contact the fan supplier to renew the bearings.
• When cleaning the fan, high-pressure cleaning or
strong dissolvent must not be used. Cleaning should
be done without dislodging the balance weights on
impeller or damaging the impeller.
• Make sure that there is no noise from the fan.
• Components in ATEX-approved products
must not
be repaired or changed.
• When destruction, materials such as copper and gal-
vanised steel can be recycled. Please follow the rele-
vant legislation, how this should be handled.
