I have PayPal, you can forward the amount in the upper right hand corner of the ducument. :D
About 10 years ago, I worked for a company that did a lot of work on AEC chillers. I remember that the quantity of refrigerant stamped on the nameplate did not reflect the actual charge in the unit in many cases. You can't just weigh in that amount and walk away, need to check operation, subcooling, ect.
They were usually in a filthy environment too, plastic molding plants. Condensers would get coated with oil from the air. Open chilled water reservoirs would get plastic dust in them and it would end up fouling up the chiller barrels.

thats where this one is located at in a plastic molding factory, everything in there is dirty, not a fun place to work in, but when its cold outside and snowing, it makes that dirty and warm area where the chiller is look a little better

If it was easy, Grandma would be doing it. Right?
The other night I was out late working on a chiller for a Trumpf laser cutting machine.
Production is down. They don't ask how much. They ask how soon.
That attitude makes process chillers one of my good friends.
