SERVICE AND LIMITED WARRANTY
All units are factory tested and guaranteed for 12 months as of the first start-up or 18 months as of delivery.
These units have been developed and constructed according to high quality standards ensuring years of failure free operation. However,
the unit requires maintenance even during the warranty period, from the time of installation and not just from the
commissioning date. We strongly advise stipulating a maintenance contract with a service authorized by the manufacturer to ensure
efficient and problem free service, thanks to the expertise and experience of our personnel.
It must be borne in mind that operating the unit 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, to conform to warranty limits:
1.
The unit 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 an unbalance between phases exceeding 3%. The unit 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.
