hi guys
currently working on a mitsi pury-p500 connected to 13 indoor fan coils mix of splits and cassetes and im doing the full works pressure test -vac- charge, and as i am not familiar with this system need some advice as to wether power needs to be kept on to allow valves to stay open on bc box and lev etc . i am told that all indoor units power needs to be isolated but then i am told that disconnecting the transmission wires on the outdoor unit will do the job with the condenser left on is this normal practice ? and if so is this sort of procedure just done on mitsi's? any feedback appreciated i dont want to mess this up with a simple but tedious mistake.
cheers .
