good morning, I have a doubt about how to know if a minisplit york lacks refrigerant, the thing is that the minisplit is installed correctly, it was emptied, but the detail is that it freezes only at dawn, if it cools well but then it freezes, I already check the low pressure with pressure gauges and it is at 55psi, the refrigerant is r22 I also want to know about the data plate that brings what amperage to take to know if it is working well since in the condenser it brings two plates of data and I don't know which amperage to take from both. otherwise I suspect that it is a lack of refrigerant because when it was installed in minisplit at the time of removing the blue hose from the condenser a lot of refrigerant was fired since at that time the unit was turned off and then if it was something that was voted on and does not have leak because he emptied if it was done correctly and the needle never came back. I leave a photo so they can tell me about the amperage. it was objected that in one it says 9.05 A and in the other it says 11.43 A

How much amperage does the reading you did give?
