TROUBLESHOOTING GUIDE
The fan does not start
The fan is newly installed and has never been started
• Check that the fan impeller runs freely by spinning it.
• Check the position of the safety switch.
It should be in position I, which corresponds to On.
•
Remove the cover and disconnect the power supply to
the fan by moving the safety switch to 0. Then return the
switch to 1.
•
Check that there is voltage at terminal block L. (May only
be performed by an electrician.)
•
Check that neutral is properly connected by measuring
the voltage across L-N. (May only be performed by an
electrician.)
If the fan still fails to initiate the startup sequence, which in-
volves the LEDs lighting up in sequence and the motor starting
after a short time, you can return the fan as long as it is within
the warranty period and you have a receipt. See Guarantee on
page 15.
The fan has been in use for some time
• Check that the fan impeller runs freely by spinning it.
• Remove the cover and restart the fan by turning the safety
switch off and then on again. Leave the fan switched off
for about 3 seconds before switching it back on.
• Perform a factory reset by holding the SPEED minus button
for at least five seconds.
If the LEDs light up in sequence but the motor does not start, you
can return the fan as long as it is within the warranty period and
you have a receipt. See Guarantee on page 15.
The fan has been cleaned
• Check that the fan impeller runs freely by spinning it.
