4.4.12. Installation diagram 

The installation of the plant is carried out in accordance with Hoval's specifications. 
All plant and electrical supply lines must be placed and installed in accordance with the 
installation plan or Hoval's specifications. 

An open area (working area) is required for all work on the CHP plant, in particular 
installation, maintenance and service. For work in front of the CHP plant (front), a larger 
clearance is required in order to be able to remove and insert the equipment set (engine 
and generator). The room height should be at least 2,000 mm. Deviations from the 
specified minimum dimensions may involve additional work and are only possible after 
consultation. 

Please also refer to the 

Figure 6: Installation diagram

 for the defined dimensions for 

determining the total space requirement. The dimensions and weights of the individual 
plant components can be found in the manufacturer's specifications in the technical 
documentation. 

 

Figure 6: Installation diagram 

The  dimensions  are  given  in  "mm"  and  depend  on  the  external  dimensions  of  the  CHP 
plant.
