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.
FAULT DETECTION
1. Make sure that the power is connected to the fan.
2. Disconnect the power and verify that the impeller
is not blocked.
3. Check the thermal contact (for AC). If it is triggered
the cause of overheating must be investigated and
taken care of. To restore the manual thermo-
protector the power must be disconnected for a
couple of minutes. Larger motors than 1,6 A may
have manual reset of the motor.
In case of automatic thermo-protector the resetting
will be done automatically when the motor has
cooled down.
4. Make sure that the capacitor is connected, (AC/
single phase only) according to the wiring diagram.
5. If the fan still does not work, the first thing to do is
to replace the capacitor (for AC).
6. If the previous steps doesn’t solve the problem,
contact your fan supplier.
7. If the fan is returned to the supplier, it must be
cleaned, the motor cable must be undamaged and a
detailed fault description must be enclosed.

MAINTENANCE
• Before service, maintenance or repair, disconnect
power and wait until the impeller has stopped.
• Attention, look out for sharp edges and corners.
• Consider the weight of the fan when removing or
opening larger fans to avoid injury and damage.
• 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 regularly, at least once
a year to maintain the capacity and to avoid unba-
lance which may cause unnecessary damage of the
bearings.
• When cleaning the fan, high-pressure cleaning or
strong dissolvent must not be used. Cleaning should
be done without displacing or damaging the impel-
ler.
• The fan bearings are maintenance-free and should
be replaced 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.
