What are the different pressure limits for a DualSun installation?
The inflation pressure of the expansion tank (which is not always mandatory :
Is it necessary to have an expansion tank with a DualSun SPRING installation? ) and the maximum pressure of the solar circuit at panel-level are given in the following table:
| Heigth between the panels and the solar station [m] | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 |
| Service pressure [bar] | 1,5 | 1,7 | 1,9 | 2,1 | 2,3 | 2,5 | 2,7 | 2,9 |
This tab follow the rule Pmax =1,5 + H/10
These pressures must not be exceeded in order for the warranty to remain valid.
