what should i charge to when replacing the TXV
long story short lennox unit bad txv wouldn't adjust 30 degree superheat found brass shavings inside the txv.
I ended up flushing the lines changing the filter dryer and txv. i used an Emerson txv instead of another lennox txv. now my question is, do i charge the system to the condenser requirement of a 6 degree approach and 3 subcool or what Emerson wants a 10 degree subcool?
