Hi David, thank you for your collaboration, I am going to try with the equipment in progress to loosen the valve plug because what could happen to me is that this valve loose because it had locked me before, and if I have this loss I will have to pack, get me a doubt, in order to recharge R410 to a team, should I do it on the go? thanks greetings.
Usually it is done with the equipment in progress but you are adding it little by little ((from squirting)) since you are loading by low pipe and it is the one that sucks and goes directly to the compressor in case of opening the valve of the container and blow gas can suck in liquid form. This r410 gas is loaded with an inverted container (legs up) as it is a mixture of 2 components. It is called charging gas in liquid phase. With equipment running you have better control of the load and looking at the pressure you do not go over refrigerant
Yes, the R410 allows recharging without having to take out the gas that is inside the equipment
