Maintenance Contract - Trane CGCN Installation Operation & Maintenance

Maintenance contract

These units 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 Trane Service in order to ensure efficient and
problem-free operation, thanks to the expertise and experience of our personnel.
It must also be taken into consideration that the warranty period requires maintenance, as well, as do the
warranty terms.
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 in particular, in order to conform to warranty limits:
1. The unit cannot function beyond the catalog limits
2. The electrical power supply must fall 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 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 bypassed.
5. The water used for filling the hydraulic circuit must be clean and suitably treated. A mechanical filter must be
installed at the point closest to the evaporator entrance.
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.
