Replace the bearings
This job is to be done by the Technical Service centre after carefully inspecting the bearings. It is advisable
to replace the bearings after:
36.000 hours of operation if the compressor is used in normal conditions (ambient temperature up to 25°C).
20.000 hours of operation if the compressor is used in harsher conditions (ambient temperature up to 40°C).
6.1.9 Cleaning the filters of the electrical cabinet
Clean the filters (1) once a month by unscrewing and removing the guard (2) and blowing them with
compressed air.
If the machine works in a dusty environment, it is advisable to clean the filters more frequently based on
their condition.
Replace the filter after it has been cleaned five times or if the environment is particularly dusty.

The fan of the inverter and the supplementary fan above it are to be replaced every 20000 hours of
operation.The bearings of the radiator fan are to be replaced, in normal conditions of use, every 12500 hours,
whereas they are to be replaced every 6000 hours in the case of harsher working conditions (ambient
temperature up to 40°C). To remove the fan, contact an authorised centre for its replacement.
