7. Maintenance
Maintenance must be performed by qualified technicians.
•
Replacing the batteries with different powered batteries is not recommended. They should always be 12V and 18Ah.
•
We recommend checking the batteries at least once a year and replace them each 4 years.
•
If there is a failure or problem check the operation of the control panel with the indicators.
• The bearings are greased and sealed for life. Nevertheless, changing them about every 25.000 hours effective running
time is recommended.
• If the fan is not equipped with an air filter, the only maintenance required is to clean the impeller; this must be carried
out at least once every six months.
• Care must be taken when cleaning the impeller, in order not to affect its balance.
• Use of chemical cleaners or aggressive substances is not advisable, as they could damage the equipment.
• If a part must be replaced, consult the distributor.
