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.  

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 

BPHE

 inlet. 

6. 

The value of the 

BPHE

 water flow must be included in the declared range for the unit considered, refer to the 

CSS

 selection 

software.
