6. MAINTENANCE
Proper maintenance is crucial for durability of the machine in operation and optimum performance and to ensure
the security provided by the manufacturer.
For reliable use in time of the group it is necessary to make a limited number of routine maintenance operations.
For this follow the instructions of the booklet Maintenance 0MDL178 (provided with the documentation supplied
with the unit) to which we give the maintenance schedule based on hours of operation:
Service Road mode program (Abbreviation SEr)
Working hours 100 800 1600 2400 3200 4000 4800 5600

To ensure consistent performance of the machine, it is recommended to clean the condenser at least every six
months. This operation can be performed by compressed air (directed from the inside towards the outside), with
the help of a brush with soft bristles and taking care not to damage the fins. If the condenser presented residuals
removable with the operations described above, may be recommended her washing. A suitable product is the DEK
34 Alluter by Unison or equivalent. Always be sure to follow the specific instructions of the manufacturer.
