Carrier 30 XA high pressure

[Palkoper]

Hi Guys just want make sure if I am right with High Pressure diagnose on CARRIER 30 XA water chiller . So all fans are Ok ambient temperature is 10 degrees and after 5 - 6 hours chiller stop working cos of HP . All condenser and fans are OK but I found small leak on pressure relief valve see picture ...


It could be problem with refrigeration or not really ....

BTW chiller when is starting is so NOISY with hissing noise .



Thanks 4 any advice


Cheers
