Re: Vacuum Rise Test Misconceptions
These were Toshiba 3-Pipe heat recovery systems. The outdoor unit isolation valves are not opened until the the strength pressure test, the leak pressure drop test and the moisture indicating vacuum rise test are all complete.
The unit was put into operation on a Friday. They called me on the Monday.Only the dogmatist says he will never change his mind. We all know that some of our opinions are wrong but none of us know which they are for if we did then they just wouldn't be our opinions. - JS Mill.
