Do you have to remove all refrigerant, just top it up if necessary.
No doubt about that .As for the recovery-yesterday i accidentally found that my discharge gauge is loosen (it was glued with something like liquid PTFE),so there is a chance some air was in the system,so after i fixed the gauge,i decided to evacuate again just to be sure that everything is fine .
Now at 24C ambient temperature and 2000 rpm my suction pressure is about 2 bar and discharge is about 16bar,when the fan is running,which i think are good readings
