CLEANING AND MAINTENANCE
CAUTION! Before carrying out any cleaning or maintenance work, disconnect the unit
from the mains electricity supply!
ROUTINE MAINTENANCE
The user is duty bound to have all maintenance operations carried out by trained and qualified personnel only. If the
unit has to be dismantled, protect hands with work gloves.
Monthly checks:
- Ensure that the fan impellers are clean. If they are dirty, clean them by suction so as not to damage them.
- Check the whole of the electrical part and in particular that the electrical connections are tight.
Yearly checks:
- Check the whole of the electrical part and in particular that the electrical connections are tight.
- Check the tightness of all the bolts, nuts and whatever else may be loosened by the constant vibrations of the unit.
- Check the motor for dust, dirt or other impurities. Periodically check that the motor works without unusual vibrations
or noise and that the fan inlet is not obstructed, which could otherwise leading to overheating of the windings.
- Check the fans for dirt or any foreign matter.
CLEANING THE AIR FILTER
The unit is fitted with an air filter on the fan inlet. During normal operation the filter holds back impurities in the air.
The filter should be cleaned periodically to keep its filtering properties and the airflow to the fan unchanged.
It is advisable to clean the filter at least once a month, proceeding as follows.
1. Take out the filter.
2. Place the filter on a flat, dry surface and remove the accumulated dust with a vacuum cleaner.
3. Wash the filter with water and detergent (no solvents).
4. Leave the filter to dry in a ventilated place in the sun.
5. Replace the filter when it is perfectly dry.
Clean the filter at the beginning and end of every season.
N.B.: the filter may also be taken out from the side or from the top.
