(seal on the return flow meter, seal) 

2.  Is there a suitable installation kit available?  

(ball valves, installation parts, seals) 

3.  Is the installation kit in the right place?

4.  Is the heat meter dimensioned correctly? 

(flow qi / qp / qs, pressure, temperature)

5.  Are the geometrical connection conditions of the flow sensor, the 

temperature sensor and the immersion sleeves if appropriate suitable 
for the installation location?

6.  If immersion sleeves are used:  

Are the immersion sleeves suitable for the heat meter with regard to 

country-specific and national regulations?

7.  Are all the installation parts required available?  

(seals, screw fittings)

8.  Are all the parts required for sealing available?

9.  Is the installation manual for the heat meter available?

10. Has the system been flushed properly? 

 

(clean filters and screens)

Heed national and country-specific regulations!
