Cleaning and maintenance
Accumulation of dust and dirt at the back of the device will negatively influence the performance
of the fan. Cleaning the backside of the fan at least once a week is required for an optimal
performance. This fan is very safe and easy to clean:
1.
Switch the device off and pull the plug
2.
If used continuously (24 hours/day) under normal circumstances, we advise that the
accumulated dust is cleaned once a week from the air inlet at the back of the device and at
least once a month at the air outlet. Clean once a month the outer surface with a cloth.
3.
If necessary clean the rotor gently with the vacuum cleaner on a low level. You first have to
loosen one screw with the screwdriver and take away the grid at the back.
Attention: put the grid back in place before using the device again.
4.
If necessary you can use a soft cloth with a neutral cleaning product dissolved in warm water
(below 50°) to clean the outer side of the fan. Dry carefully.
5.
If the fan is not used for a longer period of time, we advise to clean the device carefully and let
it dry. The device has to be stored in a cool and dry place.
