Service and limited warranty
All machines are factory-tested and guaranteed for 12 months as of the first start-up or 18 months as of delivery.
These machines have been developed and constructed according to high quality standards ensuring years of failure-free
operation. It is important, however, to ensure proper and periodical maintenance in accordance with all the procedures
listed in this manual.
We strongly advise stipulating a maintenance contract with a service authorized by the manufacturer in order to ensure
efficient and problem-free service, thanks to the expertise and experience of our personnel.
It must also be taken into consideration that the unit requires maintenance also during the warranty period.
It must be borne in mind that operating the machine in an inappropriate manner, beyond its operating limits or not
performing proper maintenance according to this manual can void the warranty.
Observe the following points in particular, in order to conform to warranty limits:
1.
The machine cannot function beyond the specified limits
2.
The electrical power supply must be within the voltage limits and without voltage harmonics or sudden changes.
3.
The three-phase power supply must not have un unbalance between phases exceeding 3%. The machine must
stay turned off until the electrical problem has been solved.
4.
No safety device, either mechanical, electrical or electronic must be disabled or overridden.
5.
The water used for filling the water circuit must be clean and suitably treated. A mechanical filter must be installed at
the point closest to the evaporator inlet.
6.
Unless there is a specific agreement at the time of ordering, the evaporator water flow rate must never be above
120% and below 80% of the nominal flow rate.
