For technical data please see the product label.
Before starting, make sure that:
• the current does not exceed more than +5% of what
is stated on the label.
• the connecting voltage is in b6% to –10%
of the rated voltage.
• no noise appears when starting the fan.
The warranty is only valid under condition that the
fan is used according to this “Directions for use” and
a regular maintenance has been made and record. The
warrantor is responsible only for the operation if app-
roved accessories are used. The warranty does not cover
product failures caused by accessories/equipment from
other manufacturers.
• Before service, maintenance or repair begins, the fan
must be tension free and the impeller must have
stopped.
• Attention, look out for sharp edges and corners.
• Consider the weight of the fan when removing or
opening larger fans to avoid jamming and contu-
sions.
•
Attention!
Temperatures up to 85°C can be pre-
sent on the controller housing (only for EC motor).
•
Waiting period of at least 3 minutes!
(only for
EC motor) Because of internal capacitors, danger of
death exists even after switching off the device
through directly touching the energized parts or due
to parts that have become energized due to faults.
The controller housing may only be removed or
opened when the power line has been switched off
and a period of three minutes has elapsed since swit-
ching it off.
• When cleaning and maintaining, the fan always have
to be secured when open, so it can’t fall down and
cause injury.
• The fan must be cleaned when needed, at least once
a year to maintain the capacity and to avoid unba-
lance which may cause unnecessary damages on the
bearings.
• 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.
• The fan bearings are maintenance-free and should
be renewed only when necessary.
• Notice the weight of the fan when closing after
inspection/cleaning.
• Mount back all details in reverse order. Check that
the fan is closed and locked before starting.
• Make sure that there is no noise from the fan.
1. Make sure that there is power to the fan.
2. Cut the power and verify that the impeller is not
blocked.
3. Check the thermal contact (for AC). If it is discon-
nected the cause of overheating must be taken care
of, not to be repeated.
To restore the manual ther-
mal contact, cut the power for a couple of
minutes. If it has automatic thermal contact the
resetting will be done automatically when the
motor has cooled.
4. Make sure that the capacitor is connected according
to the wiring diagram (for AC).
5. If the fan still does not work, the first thing to do is
to change the capacitor (for AC).
6. If nothing of this works, contact your fan supplier.
7. If the fan is returned to the supplier, it must be
cleaned, the motor cable undamaged and a detailed
nonconformity report enclosed.
