have you dealt with the expansion pressure as described in the FAQ on this site?

Its essential to do it properly with the system open.

Also charge it to 0.9 Bar and then pressurise to 1.5 Bar.

I suggest you follow the FAQ instructions on this site.

Manufacturer's instructions are intended for service engineers who know what they are doing!
