What is the proper measurement to charge with?
I always thought you use SH to charge with fixed orifice or distributor and SC for TXV. But even the Sporlan instructions that come with a TXV talks about charging to SH.
One of the guys I work with went on an interview yesterday and the guy asked him the proper way to charge a system. He said SH and the guy said he was wrong. He said you charge to SC. The guy didn't specify the metering device. I told the guy I work with what I said in the first paragraph and that the guy he interviewed with didn't know what he was talking about.
